AIRMETERS OR ANEMOMETERS
No. 210 No. 212
AIRMETERS AND ANEMOMETERS
Airmeters and anemometers are for the measurement of air currents in mines, tunnels,
sewers, ventilation of hospitals, public buildings, etc. The indications are obtained by
means of a delicately poised fan-wheel, the recordings being commenced by the long or
central hand, which traverses the outer circumference of the main dial, showing the passage
of 100 feet of air in a complete revolution. The enumeration can be continued to 10,000,000
feet by a series of six dials, but we strongly recommend the 4-dial instrument, reading to
100,000 feet, with a patent zero setting attachment, similar to illustration No. 210. A
disconnector projects from the band of instrument, so that the mechanism can be thrown
in or out of gear at the will of the user.
The usual way of taking a test is to place the instrument in the current in a number
of different positions; take the number of feet that have passed during a certain time, for
instance, say one minute; then divide the total by the number of readings and obtain the
average; multiply that by the square of the opening or channel, and the result is the velocity
of air, in feet, passing in a given time.

THE MINE AND SMELTER SUPPLY CO.
HEUSSER BALANCES
Manufactured exclusively for The Mine and Smelter Supply Co.
The selection of a fine assay balance requires that more than one feature, namely
sensibility, be considered. There is no single point in any balance that makes it perfect,
while all parts collectively are what comprise an instrument that is permanently accurate
stable in adjustment, and adapted to all climatic conditions.
In the building of the “Heusser Balances” each single feature has been so designed
and constructed that standing alone, it would make the balance a desirable one to purchase,
and in the whole, we offer what we know to be the most reliable line of balances made.
BEARINGS
Special attention has been given to the grinding and setting of the edges, or bearings,
which is the first principle of balance construction. Nothing but the finest “Cornelian
Agate” is used throughout, the principal being a flat surface on a knife edge which allows
the very minimum of friction, thereby increasing the speed and sensibility; all bearings are
relieved when the balance is at rest.
BEAMS
Our beams are constructed of solid rolled brass heavily gold-plated. The style on our
Type 1000 balance being a perfect mathematical truss which allows the minimum amount
of weight, retaining the greatest rigidity; such a beam is absolutely necessary where extreme
accuracy, speed and sensibility are essential. Through this construction, we have reduced
the time of oscillation to less than “thirteen seconds,” which is remarkable in balances
even less sensitive. In our other types, namely 2000, 2000-B, 3000 and “Special Mint,”
being less sensitive, they permit the use of a heavier beam which is of the same dimensions,
carefully drilled, and adjusted perfectly for the sensibility required. The distance between
the outer knife edges is 5 inches on all beams, and the upright pointer, or index, 5 inches
long. Star wheels are provided for adjustment.
RIDER DEVICE
In our rider attachment we have endeavored to construct it to reduce the time of
operating the balance to a minimum. The position of the rider on the beam is indicated
by the means of a white celluloid scale, mounted behind the beam, with sharp black gradua¬
tions upon it. The pointer is of the same material, perfectly coinciding with these
graduations on the scale, which greatly facilitates the reading, and is not so tiresome on the
eyes. The rider scale is divided into one hundred parts, for one milligram rider ten divis¬
ions corresponding to one-tenth milligram.

HEUSSER BALANCES
RIDER LOCK
Our Types 1000, 2000, 2000-B, and “Special Mint” are all provided with a rider lock,
which is attached to the main column, the intention being to have a means of locking your
rider on the hook to protect it from becoming unseated, when the balance is not in use.
RAISING AND LOWERING DEVICE
The raising and lowering mechanism of these balances is of absolutely perfect con¬
struction, being designed to allow no swing to the beam upon releasing same, and is pro¬
vided with patent permanent lubrication. They are mounted on a solid black glass plate,
which extends to the outline of the case; all metal work above this base is heavily gold-
plated.
PAN HANGERS AND PANS
The pan hangers bear upon knife edges by jeweled bearings which are brought to place
at each lowering of the beam. The pans are of silver, oxidized inside, so that the least
particle of dust can be easily detected. The beam and pan hangers are the only parts
removed for shipping, which greatly simplifies the setting up of the balance.
CASE
One of the striking and practical features of our instrument is the construction of the
case, which is of brass oxidized, and heavily lacquered, making it impervious to all laboratory
fumes, and will not corrode. It is known that a wooden case is not satisfactory under all
conditions, being greatly affected by climatic changes, either shrinking or swelling, as the
case may be. Therefore it cannot be dustproof or work satisfactorily under these con¬
ditions. This is not true with ours. Its construction renders it absolutely non-warpable
and unaffected by all climatic changes. It is as nearly dustproof and airtight as is practi¬
cal; the door slides smoothly in pressed oil board channels and is on a perfect counterpoise.
The sheave wheels are set in paraffined wood, which furnishes permanent lubrication.
Owing to the metal construction of the case it admits an unusual amount of light, and is,
furthermore, of considerable protection against disturbing electrical influences. Regard¬
less of it being in a metal case, the balance, complete, is comparatively light, weighing only
20 pounds.
Remember our balance was awarded the “First Grand Prize,” a “blue ribbon,” at the
Alaska-Yukon-Pacific Exposition. This was the very “highest award” and given after
a thorough test. We guarantee our entire line to give perfect satisfaction, according to
their various ratings and sensibilities. If they fail after fifteen days trial they can be
returned and we will cheerfully refund your money. We recognize No Equal in the
balance line, and invite comparison at all times. If you are interested we will supply,
upon request, enlarged original photographs of every type, to enable you to study in detail
the construction of each balance.

HEUSSER BUTTON BALANCE, TYPE 1000
Sensitive to 1-500 Mg.
This balance is perfectly constructed and in every feature the result of highest class
workmanship. It is acknowledged by leading assayers as the best instrument of its kind
ever manufactured. For the comparatively short time it has been on the market it has made
an enviable record and in competitive tests has proven its superior qualities beyond doubt.
The features that go to make up this splendid instrument are rapidity of weighing,
facility of reading, stability of adjustment and great ease of manipulation.
A new departure, you will note, in the manufacture of our balances, is the metal
case, which affords absolute guarantee to maintain its form and permit smooth working
under all atmospheric conditions, prohibiting it from warping, shrinking, or swelling, being
permanently rigid, which aids materially in retaining its adjustment.
Contrary to general opinion, the case is unaffected by electrical disturbances, many
users claiming that they find it a protection against electrical influences. The beam is
hand cut and finished, heavily gold plated, and a perfect mathematical truss, allowing the
minimum amount of weight and inertia for the required rigidity, thus reducing the time
of oscillation to less than 13 seconds.
Price.Net, $300.00
We pack it in a felt padded box simple in construction, requiring only a moment to

BUTTON BALANCE, TYPE 2000 -B
Also known as the Universal Balance
Three Sensibilities. 1-100, 1-250, 1-500
In this balance we have to offer a most practical and accurate one, built in duplicate of
type 1000 with the exception of the beam, which is drilled instead of hand cut. However,
the adjustment of this beam is perfect and although it is rated with an initial sensibility
of 1-100 mg. it is capable of accepting the sensibility of 1-250 or 1-500 mg. This change
is accomplished instantaneously by our patented idea of raising or lowering the center
of gravity at will. Unquestionably for an all around assay balance it is superior to any.

BUTTON BALANCE, TYPE 2000
Sensitive to 1-250 Mg.
With the exception of the beam, the balance is identical with the No. 1000 type. The
sensibility of 1-250 mg. is chosen in order that four divisions on the rider scale may corre¬
spond to one division on the index scale. The beam furnished with this instrument is of
perfect construction, the only difference being that it is drilled rather than hand cut, the
reduced sensitiveness not requiring the truss beam.
The balance is packed in felt padded box, simple of construction, requiring but a

BUTTON BALANCE, MINT TYPE
Sensitive to 1-200 Mg
Constructed in exact design of our Types 2000 and 2000-B, yet to conform to the
ideas and requirements of the United States Assay Offices and mints. We have equipped
this balance with the enlarged pan hangers to aid the handling of larger buttons in weigh¬
ing, which is necessary in the work at these offices. The rider bar is especially graduated
0 to 5 instead of 0 to 10, this being designed especially according to the government system
of weights used in their work. It is equally practical in mine work where these features
appeal to the user.
This balance is provided with locks on each drawer as means of protection to their
contents.

To supply the demand of a high grade balance of a lesser sensibility we have been
prompted to build Type 3000, which in beam and rider attachment is a duplicate of our
Type 2000. We have departed slightly in the general construction making our base of a
solid casting with the glass plate countersunk and covering to the inner dimensions of the
case. Owing to the open construction of this base, all working parts and raising and
lowering device are above it, and enclosed in the main case as protection against dust, etc.
Every part is designed with the same care as our finest balances and a guarantee of satisfac¬

AINSWORTH’S IMPROVED MULTIPLE RIDER
320 The above illustration shows Ainsworth's Improved Multiple Rider Carrier, as
adapted to button balances, for weighing without the use of the ordinary weights as
used in the pan.
The riders maintain their original accuracy even after months of constant use, and
not being subjected to the continual handling with tweezers, do not become bent or broken.
Each rider is carried on a separate arm a short distance above the bar on the stirrup
and it is only necessary to move the number on the lower rod until it stands opposite
the index pomter, and then revolve the rod slightly, which transfers the rider from the
arm to the stirrup.
Each rider has its individual arm for manipulating and cannot become misplaced,
thereby causing an error in the following weighing.
Buttons weighing up to 42 milligrammes can be weighed with the regular carrier
and for larger capacities additional arms may be added.
When weighing a button at or near the capacity of the carrier, all of the riders may be
shifted to the stirrup simultaneously, and those not needed transferred back to their
respective arms. The figures on the iront of arms down indicating the combined weight
of the riders on the stirrups.

THOMPSON’S MULTIPLE RIDER ATTACHMENT
322 This attachment and the riders used in connection with it take the place of all flat
weights on button balances for weighing up to 72 milligrammes, and on analytical bal¬
ances up to 720 milligrammes. The attachment is very simple, being operated from the
outside of the balance case. It consists of a movable wheel or carrier with seven arms,
each arm carrying a rider of different weight.
On button balances the riders used are 1, 2, 3, 5, 10, 20 and 30 milligrammes, and on
analytical balances 10, 20, 30, 50, 100, 200 and 300 milligrammes. The end of each rider
is formed to indicate its weight.

BUTTON BALANCE, STYLE No. 5
5 -inch Beam. Sensibility 1-500 Mg.
324 This balance is designed and built for the most delicate assaying, and has
advantages of superior durability and extreme accuracy. It is of the non-column type,
with upright pointer. This principle of construction gives plenty of room for a long pointer,
plainly indicating the slightest movement of the beam and greatly reducing the length
and weight of hangers, thereby tending to concentrate the movable mass near its central
axis, and so creating the greatest possible stability of poise with the least possible resistance
to the most minute Toad in the pan.
The scientific construction of the beam will appeal to the engineer. It is of the truss
type and is so constructed that all trusses are in tension, the lower chord alone being in com¬
pression.
Special attention is called to the fact that the graduations are on the beam. In this
balance we use an etching process, which in no way affects the density of the metal, and the
readings being taken direct from tne position of the rider on the beam, there is no possibility
of error through any difference between the relative position of the rider and the graduations.
The agate edges and bearings are of the finest quality and workmanship, and in this
balance we spare no time or expense in bringing the various adjustments to the highest
point of perfection.
The rider apparatus, having fine felt bearings in contact with polished metal surfaces,
gives a smooth and noiseless action, and is very sensitive to the touch.
The balance has a star wheel balancing device, skeleton hangers, fall-away pan-rests,
rider rod locks, levels and leveling screws. The beam and index are provided with special
ground cylindrical reading glasses, and all exposed metal parts are gold plated.
The case is of mahogony, thoroughly seasoned and finely polished, and has counter¬
poised door. A black glass-plate extends over the entire bass.

Beam, 7-inch (17.7 cm.). Sensibility, 1-20 (.05) Milligram.
Capacity, 200 Grams (8 ounces).
382 The beam is made of cold rolled aluminum, alloy having more than three
times the tensile strength of pure aluminum, and being rolled (not cast) under high pressure
rolls, all the invisible defects in the mass are eliminated and a great uniform density is
secured throughout the sheet. From this sheet the beam is “ Jigged,” and this gives to
the finished beam great stability, so that it will maintain its adjustment over a wide range
of temperature change. The beam is then oxidized black with a non-corrosive preparation
and divided into fifty parts each side of the center knife. These divisions, for legibility,
are white, the beam is unobstructed on the top and the rider can be placed at any point.
The case is old, well seasoned mahogany, French polished; the top of base is covered
with a black plate glass; the front sash is counterpoised, opening up the full width of the
case; the rear sash also slides up, allowing the weighing of long subjects extending beyond
the outside lines of the case; the top and ends are also fitted with glass sash, thus securing
plenty of light from all directions. Size, 19x19x11 inches (48x48x28 cm.).

PULP BALANCE, STYLE No. 35
7-inch Beam. Sensibility Mg.
400 Special attention is called to the construction of the center bearing in this
balance. It is an agate plane, instead of a groove as in most balances of this class, the
advantage being that the contact with the knife edge can be easily kept clean, and when the
balance is not in use, the knife edge does not rest on the bearing. In all pulp balances that
have a grooved center bearing it is necessary to have a plate cover each end of the groove
in order to keep the beam in place. This forms a corner in which the dust from the pulp
collects, surrounding the knife edge, and preventing free oscillation.
The balance has steel edges and agate bearings, adjustable pan-rests, three-inch metal
pans, fly balancing device, level and leveling screws. Mahogany case with counterpoised
door. Dimensions, 17 x 8 x 15 inches.
Price. $35.00

MOISTURE SCALES
No. 602
502 Used at smelting and similar plants for determining the percentage of
moisture in ores, etc. The ordinary capacity scale is made to weigh a sample of 50 ounces,
but special scales are manufactured to order, of other capacities as described, below. The
scale beam has two rows of graduation, the upper row giving the weight in ounces, or pounds,
and fractions thereof; the lower row giving the percentages. The percentage row on all
scales is figured 100 to 0 per cent, by 1 per cent, and thus the reading gives the direct per¬
centage of loss. The given amount of ore is first weighed, then dried or roasted, and re¬
weighed to note the loss of moisture or sulphur. From 50-oz. to J^-oz. capacity.

ANEROID BAROMETERS
Fig. 2 Fig. 3
ATMOSPHERIC PRESSURE
The atmosphere surrounding the earth may be regarded as an “Ocean” of air, ex¬
tending upwards from the earth’s surface about ten miles above sea level. Its greatest
density is nearest to the earth’s surface, by reason of having to support the weight of its
whole depth; and it gradually becomes less dense as the distance from the earth increases.
This law of decrease in pressure being known, is used as a means of measuring the height
of hills and mountains.
ANEROID
The word Aneroid is a Greek compound, expressing “without fluid.” Aneroid
Barometers are frequently termed “holosteric” barometers, but this is merely a fancy
name to distinguish our present form of flat spring (“D ”) instrument from the older and less
perfect spiral spring form.
CONSTRUCTION—VACUUM CHAMBER, “A”
The illustration (Fig. 1), shows the general construction of the movement with its
elastic metallic box, called the vacuum chamber, “A.”
This chamber is constructed with two circular discs of thin corrugated German silver,
firmly soldered together at the edges, forming a close box, as shown in Fig. 2. The air is
exhausted from this box, which causes the top and bottom discs to close together, as shown
in Fig. 3. The pressure of air upon the outside surfaces of an ordinary size chamber is equal
to a force of about 60 pounds.
The vacuum chamber, “A,” is firmly fixed to the circular metal base, “B,” by a post
upon its center, projecting through the base plate.
BRIDGE, “C”
An iron bridge “C,” spans the chamber, resting upon the base plate by means of the
two pointed screws, c'c'. (These screws are used to finely regulate the tension upon the
chamber, “A”.)
To the bridge “C,” is fixed the mainspring, “D,” which is forced down by mechanical
means sufficient to insert the knife edge piece, “E.”
Digitized by v^ooQle
THE MINE AND SMELTER SUPPLY CO.
ANEROID BAROMETERS
As this knife edge is fastened (by means of a central pillar) to the top disc of chamber
“A,” the mainspring, “D,” when released, lifts the upper part of the chamber, drawing the
two discs asunder so that the box again has the appearance as shown in Fig. 2.
As this forms a perfect balance (the power of the mainspring opposing the atmospheric
pressure upon the vacuum chamber), any variation in air-pressure will now be shown by a
movement up or down of the elastic chamber. A decrease in pressure will allow the main¬
spring to overcome the power of the vacuum, the action then being upwards, and an increase
of air-pressure will produce the contrary result.
INDICATING HAND SHOWS RESULTS
This vertical action of the vacuum chamber is multiplied and converted to a horizonta
movement of the indicating hand by a series of mechanical movements as follows:
Being attached to the mainspring, the lever. “F,” is actuated by the movement of the
chamber. It is attached to the short lever, “G, and again to the long lever, “H.” From
it, a fine chain extends to the center of the movement, passing around a central arbor or
spindle, “I,” upon which the indicating Hand, “ J,” of the Barometer is fixed, now having a
horizontal motion, parallel to the Dial. The projecting arm, “K ” carrying two small pil¬
lars, with a cross piece, “L,” supports the central arbor or spindle.
The short lever, “G,” projects from regulator, “M,” and is provided with an adjusting
screw, “ N.” This, being capable of lengthening or shortening the lever, provides an adjust¬
ment by which the indicating Hand of the Barometer may be set to the correct position upon
the Dial. This is done by turning the adjusting screw which passes through the base plate
at the extremity of the bridge, (“O”).
ADJUSTMENT
As there is sometimes a settlement of some of the metal parts and springs which alters
the position of the indicating hand, it is advisable, whenever an opportunity offers, to com¬
pare the readings of an Aneroid with a standard Mercurial Barometer. If they do not agree,
the Aneroid may be adjusted by turning the small adjusting screw until the indicating hand
on the dial coincides with the height of the mercury column.
COMPENSATED
In the best made instruments the main lever, “G,” is made of a composite bar of two
metals, steel and brass, the quantity of each metal being altered until it is correctly com¬
pensated, for any change in temperature. This averts the necessity of making allowances
for changes in temperature, as is necessary in reading a Mercurial Barometer.
IN GENERAL USE BY OBSERVERS
The Aneroid, owing to its portable form and great sensitiveness in responding to
changes in pressure of the atmosphere (it will denote*a change much quicker than the Mer¬
curial Barometer), is to-day in more general use by observers of meteorological changes than
any other form of Barometer.
ADVANTAGES
The Aneroid is indispensable to the navigator, as the motion of a ship renders a Mer¬
curial Barometer so unsettled. In measuring altitudes, owing to its portability, sensitive¬
ness and the ease with which approximate results may be obtained, it is highly valuable to
the Engineer and Surveyor, while the Tourist, with the Aneroid, notes his gain in elevation
foot by foot, as well as plans his excursions in accordance with prognostications from its
readings.

EDISON-BSCO PRIMARY BATTERIES
Edison-Bsco Cells are equally suitable for open circuit (intermittent discharge) or
closed circuit (continuous discharge). It is important that the proper number of cells be
used to furnish the necessary working voltage and that the type selected be large enough
to deliver the current required. In cases where the flow of current will be comparatively
high (3 to 5 amperes) or where the circuit will be closed continuously at other than very low
current rates, cells of high capacity should be selected, as the larger types have low internal
resistance and long life, thus giving best results at lowest maintenance cost.
The open circuit, or initial voltage of all cells is .95 volt per cell; but in all batteries the
initial voltage is higher than the effective or working voltage on continuous closed circuit.
The high initial voltage is effective for work only when cells are discharged at an extremely
low current rate, and in some cases, such as with ordinary dry cells, even at low rates of
discharge it is available only for intermittent contacts of short duration.

SUGGESTIONS FOR SETTING UP BUNSEN CELLS
The zinc should be well amalgamated, the porous cup filled with diluted nitric acid,
and the glass jar with water to within one cm. in.) of the top of the porous cup. For
stronger action, a small amount of sulphuric acid may be added to the water in the jar,
using not more than one part of sulphuric acid to twelve of water

SUGGESTIONS FOR USING CROWFOOT CELLS
In this cell, after placing the elements in position, fill jar nearly full with water, then
drop in crystals of copper sulphate, about 500 grams to each cell. The elements should be
connected for a short time before using until a distinct separation is seen in the fluid of the
cell, the lower part being of a deep blue coloration, and the upper colorless. If it is desired
to hasten this action, add a saturated solution of zinc sulphate to the upper liquid. The
line between the blue and the colorless solutions should be about midway between the zinc
and the copper; when it is lower than this a small amount of sulphate of copper should be
added to the cell. If higher the cell should be put on a short circuit until this mark is
reached, or a portion of the copper sulphate solution may be drawn out, and the cell re¬
filled with water.

SUGGESTIONS FOR USING DANIELL CELLS
After placing elements in position fill the porous cup with a diluted solution of sul¬
phuric acid, one part acid to 20 or 25 parts of water, or with a 25% aqueous solution of
zinc sulphate. The glass jar outside the porous cup to be filled with a saturated solution of
copper sulphate, and the pocket of the copper should be filled with copper sulphate to
keep the solution saturated.

JENA LABORATORY GLASSWARE
The Jena Laboratory Glass Appliances are made of a material which possesses a
greatly increased power of resisting sudden changes of temperature and the action of
corrosive chemicals. This glass is therefore much safer and more reliable for labora¬
tory use in chemical and physical research than any other glastf hitherto employed for
the same purpose.
Tests made at the Physical Institute of the University of Jena have shown that the
Jena Laboratory Glass may be employed without hesitation for heating liquids over a
powerful Bunsen flame without wire-gauze. This, as compared with the same flame
used with wire-gauze, represents a saving of approximately 58 per cent of time and 60 per
cent of gas.

Illustration shows rotary flame combination furnace No. 40 with gas burner and
combination motor and blower.
COMBINATION MOTORS AND BLOWERS
The combination motor and blower shown in illustration is especially designed for use
with the Braun Gas Burner. It is made in the most substantial way possible. The motor
will develop more power than is required by the blower, which insures it a long life and free¬
dom from overheating.
This combination motor and blower will easily operate three gas burners. The cost
of operating is very low, being practically the same as that of a sixteen candle power electric
light.
These blowers are made to operate on either 110 or 220 voltage for both alternating
and direct currents.
In ordering please state voltage if direct current is to be used, and the voltage and
cycles if the alternating current is to be used.

and air, requiring only a slight motion of a small lever to obtain instantly any flame from
the smallest to the largest. It is made for coal gas only.
All automatons have the delicacy of the best mouth blow pipe used with the utmost
skill, with the power and advantages obtained with a mechanical blower.
Price..each $4.00

824 Blow Pipe, Fletcher’s Patent No. 42 . The arrangement of the Fletcher Blow
Pipe (No. 42) is totally different from that of any other made. The ordinary form has
been entirely discarded, and every detail has been specially designed from practical
experience as to the requirements of users. The Mouthpiece is, of all, the easiest to use, and
the heaviest continued blowing causes no strain on the lips, whilst the tongue has the
necessary control over the opening. The blow pipe proper is held as a pencil. The chamber
on the stem stops all condensed moisture and prevents the heat traveling up the shaft.
With Cold Blast and Hot Blast, Two Jets, Nickel-plated Mouthpiece.$1.50
826 With folding stand adjustable at any height or angle. It can be used either with
the mouth, or the small hand-blower can be attached and tne blowing done by pressure of
the fingers. With this blow pipe is supplied one jet with and one jet without the hot blast
coil, to enable a large variety of flame to be obtained. The lamp or a weight should be
placed on the stand when in use.

1166 Burner, Bunsen. Self-adjusting Bunsen Burner, for burning gases of various
qualities.
The special features of this burner are the following:
By turning the knurled part, you can increase or lower the flame, the flow of gas and
air being regulated automatically, and therefore the burner will always retain a blue flame.
The supply of air is regulated by inserting the screw into the next slot, either to the
right or to the left. Care must be taken that the screw is not inserted into the slot too
tightly, as this will interfere with the turning of the burner.
If a yellow flame should be desired, separate the set-screw from burner-tip, allowing
the gas and air to be regulated separately. This is the best self-adjusting Bunsen burner
made, and we can recommend it to give entire satisfaction. Height 6 inches, diameter of
tube, V 2 inch.

leakage of gas, as on others. From a delicate pointed jet to a large
powerful flame can be obtained by a movement of the lever which
adjusts both air and gas automatically. When the lever is turned
to the right a small flame is produced; to the left a large flame, and
when in the center the gas is turned on, allowing only the pilot light
to bum. The pilot light may be kept burning continually if desired,
it being unnecessary to light the burner every time it is to be used.

CENTRIFUGES
FOR THE EXAMINATION OF URINE, BLOOD, AND MILK
For hospitals, colleges and
laboratories where the electric
current is to be had, the Purdy
Electric Centrifuge is the greatest
possible convenience. By means
of the electric current a uniform
speed can be maintained for any
length of time desired, and deli¬
cate tests can be made which
cannot be easily gotten from a
handpower machine where the
speed varies.
These new centrifuges are
provided with a lever for regu¬
lating the speed.
We furnish this centrifuge
to work on either the direct or
alternating current. In order¬
ing please state the current it
is to be used upon, giving also
voltage, cycles, etc. When cen¬
trifuge is to be used on 220-volt
current, add $10.00 to prices

MINER’S COMPASS OR DIPPING NEEDLE
1454 In the hands of the prospector the Miner’s Compass or Dipping Needle
proves a serviceable guide to the discovery and location of magnetic iron ore. In this in¬
strument the magnetic needle is carefully balanced upon a horizontal axis within a graduated
circle, and in which the needle will be found to assume a position inclined to the horizon.
This angle of deviation is called the inclination or dip, and varies in different latitudes, and
even at different times in the same place. Hence, in reading the dip for the suspected
presence of magnetic iron ore, the observer must not only be governed by his instrument,
but must also draw into requisition his knowledge of the general geological formation of the
place of his survey; and dependant on his experience, he will be enabled to approximate as
to the probable mass and depth of the ore from the surface. When used for tracing ore the
observer should hold the ring in his hands and keep the needle north and south, standing
with his face to the west. The inclination of the needle as read off on the graduated scale
will show the dip. If the compass is held horizontally it serves of course as an ordinary
compass.
Price, with 3-inch Dip Needle in Velvet Lined Case. $12.00
Same as No. 1454 Norwegian pattern needle gimballed. 20.00

GRAPHITE CRUCIBLES
THEIR CARE AND USE
Many foundrymen do not fully appreciate the importance of keeping and handling
their crucibles in a manner which will insure the greatest number of heats with the least
danger of accidents, and this is published to emphasize this point.
The importance of the subject seems to be underestimated, and crucible users will
find it to their advantage to give the matter more thought and attention, and instruct
their furnace men, melters and other employees accordingly.
As any defect in, or accident to, a crucible is an exceedingly annoying as well as an
expensive matter, and as such occurrences are in most cases due to improper or careless
methods in the annealing or handling of crucibles, the suggestions embodied on this page
should prove valuable, as they are the result of long experience and the best thought and
knowledge on the subject.
It is very important that the crucible should be properly annealed in a temperature
of at least 250 degrees Fahrenheit before using.
Concerning a proper method of annealing, there can be no fixed rule, as conditions differ;
but it is the general practice to anneal on the top of the furnace, although some foundries
are equipped with a furnace used exclusively for this annealing purpose, and it is an interest¬
ing fact that such foundries never have “scalped” crucibles.
Whether annealing in a special furnace or on top of the crucible furnace, there are four
points that must be observed:
First: The temperature must go above 250 degrees Fahrenheit.
Second: This temperature should be reached gradually.
Third: This temperature must be held a sufficient time to allow the moisture to
thoroughly disappear.
Fourth: • The crucible must go in the crucible furnace with a temperature above 250
degrees Fahrenheit.
For example, with a No. 200 crucible it should take at least ten hours to bring it up
to this degree. It should “soak” in the heat fully ten hours and then be charged and go in
the furnace at about this heat.
Some foundries practice the first, second and third rules perfectly and “fall down”
entirely on the fourth by hurriedly and carelessly taking the crucible from the furnace and
placing it on damp sand or a cold furnace floor and allowing it to stand there indefinitely
before charging.
A failure to comply with this fourth rule counteracts all that the other three have
accomplished, and the crucible maker may be informed that his pots are “no good.”
Unless the annealing is carefully done, however, hidden cracks, flaws or fissures may
be present which, under strong heat, may cause pin holes and similar defects to make their
appearance.
Pin holes are one of the chief difficulties that the user of crucibles meets. Crucibles
do not usually show this defect until they have been in use for some time. It seems to
require a number of heats to develop this defect.
Pin holes are usually discovered by metal dropping down into the furnace pit, and when
the crucible is removed a stream of metal will be found trickling down its side.
Pin holes are probably small fissures developed either during the drying or the anneal¬
ing of a crucible, and there seems to be no way of avoiding an occasional defect of this
kind.

COLORADO CLAY GOODS
Colorado Clay Goods, for which we are sole agents, are manufactured from the
highest grade clay by expert clay workers of many years of experience, making use of many
experiments upon all different makes, as well as their own. We can say with confidence
that the “Colorado” Crucibles, Scorifiers and Muffles will give the assayer entirely sat¬
isfactory service, and reduce his expense for these items to a minimum.
These crucibles are not excelled for cleanness of pouring and evenness of cutting; as the
bottom is small, the lead button is not spread out over a large surface and in danger of a
portion being lost.
Crucibles are subjected to the most severe service imaginable. The abrupt heating
induces strains due to expansion which are hard to withstand. In addition to this, they are
subjected to a chemical action on account of the charge within. Our crucibles will meet
these most exacting necessities, but in order to reduce the strains to a minimum, we wish to
state the following:
MAXIMS FOR THE CARE OF CRUCIBLES
1. Crucibles, on account of the texture necessary, must be more or less fragile, and
despite the utmost care in packing, there is bound to be some breakage, or at least cracking
in transit. It is well, therefore, to examine crucibles before use for such cracks, tapping
them to hear the clear ring of sound crucibles, as otherwise a crack too small to be noticed
casually may cause considerable annoyance, loss of time and patience and damage to the
muffle.
2. Crucibles should be dry before use. In putting crucibles into a furnace, it is well
to bring up the heat as evenly as possible. Clay is a very poor conductor of heat, and the
crucible may be very hot in one spot and considerably cooler on the inside or on the other
side, thus producing a very severe strain. This is especially true of open crucible furnaces
where the gasoline flame strikes the crucible directly. In the Colorado Furnace, this
objection has been overcome.
In putting crucibles into a hot coke fire, it is well to put on a little fresh fuel and then
set the crucibles in this green fuel.
3. Remember that the flux may not only act upon the ore, but also upon the crucibles,
and sometimes a slight change in the flux will not make the slag less liquid and yet may
reduce the corroding effect upon the crucible considerably. The introduction of a little
silica often protects the crucible, and makes the slag more fluid.
By not going ahead heedlessly, and by observing the few suggestions given above, the
wear and tear on crucibles is considerably reduced, and an assayer can often get several
more melts out of them, and furthermore save himself time and annoyance through loss of
work.

This crucible is made for making oxygen from Mn0 2 , calcination of chalk with recovery
of the expelled C0 2 , manufacture of soda from cryolite, preparation of ammonia, destruc¬
tive distillation of coal, wood or other organic substances, or for any use in which the
materials employed or evolved do not act destructively on hot iron.
The cover is clamped air-tight to the rim by means of a strong clamp F and an asbestos
packing ring. The exit tube B enters by a straight run at A, which admits of the ready
removal of tar or other material which might obstruct the outlet. The delivery tube D,
which is used when a substance is to be treated in a current of gas or special atmosphere,
enters the head of a screw plug, C, and is extended, when desirable, to the bottom of the
interior by a short tube which screws into the bottom of the plug. When the delivery tube
is not wanted, C is removed and the solid plug G inserted instead.

No. 1560
1560 For laboratory and assay office use, the No. 00 Samson Laboratory Crusher is
one of the best machines of its kind on the market.
It is extremely simple, has a large capacity, requires only a limited amount of power,
and can be operated either by hand or with a belt.
It can be easily cleaned, as shown in the cut, by pulling down the eye bolt on the front
oscillating journal seat. This allows the front journal to drop down, the swinging frame
that holds the stationary jaw plate to be turned up as shown, exposing the stationary as
well as the movable and side plates for cleaning. No tools are required to open and close
this crusher, and the time required is but an instant; it can be opened and cleaned while
running at full speed.

In the improved chipmunk crusher herewith presented many changes have been
made from the original pattern as formerly supplied. The height of the steel frames has
been reduced and broadened so as to give the machine greater rigidity. Vibration is re¬
duced to a minimum.
A New Feature. In the 1911 model we have improved the adjusting device. This
consists of an eccentric bolt passing through the adjusting block. By moving the lever
at the side of the machine backward it decreases the opening between the jaws; by mov¬
ing it forward or towards the operator, it increases this opening. A safety clamp is placed
in one of the notches which prevents the stationary jaw being brought in contact with the
movable jaw.
All bearings are fitted with grease cups.
The vibratory jaw is mounted upon an eccentric at its upper end and rests against
a toggle near its lower end. The eccentric imparts a circular or gyratory movement to the
upper end, while the toggle compels the lower end to describe an arc of a small circle. This
motion is both forward and downward and impels a discharge.

The frame is made of steel, each side being made in one piece, and both rigidly secured
together with strong studs. Strength, durability, and lightness were secured by the em¬
ployment of steel frames.
No. 3 IMPROVED CHIPMUNK CRUSHER
This is one of our latest designs, being much larger, stronger, and of larger capacity
than the types formerly offered. The steel frames have been shortened and widened, and
when mounted on the special blocks furnished with each machine there is very little vibra¬
tion. It is fitted with heavy flywheels, which reduces the power required for operation to a
minimum. It has the largest capacity of any crushing device with jaws of similar size;
when hand fed it will reduce rock from about 2 inches down to mesh and smaller at the
rate of 1000 to 1500 pounds per hour, and when fed through a hopper, from 1500 to 2000
pounds per hour. In repeated trial runs we have found it impossible to choke this machine.
The peculiar motion of the rear jaw which is both forward and downward (a rubbing mo¬
tion) impels a discharge.

BRAUN SIMPLEX CRUSHERS
HAND MACHINE
Nob. 1570-1572
SECTIONAL VIEW
AN IDEAL LABORATORY CRUSHER FOR HAND OR POWER
(Patented April 15, 1902)
The simplex ore crusher is designed for crushing small samples of ore by hand.
We manufacture the same machine with broad wheel for belt for those desiring to use
power.
Important features of this machine are: The ease with which it may be opened for
cleaning and the simplicity of its adjustment.
One blow of a hammer loosens the wedge holding the non-vibrating jaw in place,
allowing this jaw to be lifted out. thereby giving sufficient access for ordinary cleaning;
to further expose the interior of tnis crusher, the vibratory jaw can be swung clear of its
chamber without removing a bolt, screw or nut, and without the use of a tool or wrench
of any kind.
The complete opening and closing of this machine for cleaning does not take one
minute, not including the time occupied in cleaning.
The fineness of the product obtained is regulated by increasing or diminishing the
size of the discharge or lower opening of the jaws; this can be accomplished by a few turns
of two regulating screws, which havehand wheels, obviating the necessity for use of wrench
or tools.
This machine can be adjusted to crush ore to a fine powder or the size of a coffee bean.
When very fine crushing is desired, time will be saved by running ore twice through the
machine, the first time set as wide as possible, and the last time at its maximum fineness.
The parts of the simplex crusher which bear the strain are all sufficiently strong
for the purpose. The steel jaw plates are reversible and can easily be removed for renewal
when necessary.
A motor of H H. P. is sufficient to operate this crusher. The best results are obtained
if the machine is speeded to about 200 revolutions per minute.
Capacity, per hour, to }i inch and smaller, 100 pounds.

TAYLOR ROCK CRUSHERS
1574 A most powerful hand crusher, suitable for prospectors as well as assayers for working
specimen ores, crushing old crucibles, etc. This small machine will enable a person to
quickly and easily bring the hardest ores to a fine powder, and to readily crush a larger
sample than can be done in a mortar. The construction of this crusher is such that the
size of the discharge opening does not vary when the machine is operated, consequently
when the jaws are set close together a product of uniform fineness is obtained. It is possible
to pulverize an entire sample to a very fine mesh with one feeding through this machine.
The adjustment for a coarse or fine product is instantly made by turning the knob
shown in the above illustration directly under the hand.
The straps are made of steel, the stationary and vibratory jaw plates are chilled iron,
the frame and hand lever are made of cast iron; all parts of this crusher are sufficiently
strong to withstand hard usage.
Each machine has a cover (not shown in illustration) to prevent pieces of ore from
flying out, and is furnished with a wrench and dust brush.

McCOOL PULVERIZERS
The Mine And Smelter Supply Co., Sole Agents
(Patents Pending on Machine, Its Discs and Pabts)
NOS. 1584-1586
THE McCOOL PULVERIZER fills a need long felt by assayers for a machine which will
grind a sample of either hard or soft ore quickly to a very fine mesh, and which is easily
cleaned; and moreover a machine which is so perfect in mechanical design and workmanship
that it always works satisfactorily, and requires a minimum of care. They are practically
noiseless in operation.
The GRINDING is accomplished by a compound movement between two plane discs, one
being stationary and the other having a double movement—a revolution on its own shaft
and an eccentric rotation due to the revolution of a hollow shaft in which the disc shaft has
an eccentric journal. This gives a rubbing action which reduces the ore quickly, and which
keeps the disc free from corrugation and in perfect condition until worn out.
The discs may be changed in less than two minutes, and are the only wearing part
necessary to replace; their cost being low, the cost of repairs is negligible. They are made
of a composition determined after very careful experimenting to give the greatest durabil¬
ity consistent with rapid grinding. The rotating disc is attached to its shaft, so that it is free
to adjust itself to the plane of the stationary disc, and the annoying period which occurs on
other machines while the discs are wearing to a fit for proper grinding is avoided. This is
accomplished by a ball and socket joint which takes the thrust of the grinding.
The ADJUSTMENT for fineness of grinding may be made when the machine is
running, by simply turning a handwheel which automatically locks in position.

McCOOL PULVERIZERS
OPEN FOR CLEANING AND REMOVAL OFJSAMPLE
Nos. 1584-1586
The CLEANING and removal of the ground sample is easily and quickly accomplished,
as the machine is opened or closed by one operation: being held closed by a lever cam clamp,
The sample drawer is attached to the front case, which is hinged, and anything adhering to
the case or stationary disc can be brushed into the pan. The rotating disc is entirely ex¬
posed for cleaning, and all the surface of the grinding chamber is machined smoothed. It is
dust-tight, and samplers report no loss of value through dust, nor is there danger of salting,
even with ordinary care after rich ore.
The CAPACITY of the McCool Pulverizer is especially large. The small size will reduce
an 8 ounce sample to 100 mesh in 30 seconds; the large size will reduce a one pound sample
to 100 mesh in 30 seconds. The capacity, of course, is dependent largely upon the char¬
acter of the ore, the size and the mesh of the feed, and also upon the desired mesh of the
product.
The MECHANISM is not complicated, being only the application of old standard devices
to a machine for a special purpose. The belt pull is taken by a journal on either side of the
pulley which is of large diameter and ample width. The tight pulley drives the hollow
shaft, which in turn drives the disc shaft, which is eccentric in it, through a set of cut gears
similar to the back gears on a lathe. In designing the machine, particular attention was
paid to the lubrication, which is automatic and very similar to that of a high speed en¬
gine. The joumals’and the loose pulley are served by ring oilers, and the gears run in oil
noiselessly in a closed chamber. It is only necessary to see that the proper level is kept in
this chamber, which serves as a reservoir, and the machine will last indefinitely, being
practically FOOL-PROOF.
The machines are sold strictly on their merits, and any one acquainted with machinery
will on first sight be convinced of their superiority.

BRAUN SAMPLE GRINDERS
THE PLANETARY PULVERIZER
CLOSED
No. 1088
The simplicity of construction to obtain the planetary movement with the assurance
that there are no expensive parts to be replaced, combined with the fact that it is almost
as noiseless in operation as the regular Braun Pulverizer with which nearly every laboratory
operator is acquainted, will commend the Braun Planetary Pulverizer to those in need of
a machine for grinding all classes of material, whether hard, soft or talcy.
The planetary movement prevents soft material from caking on the plates and insures
proper discharge. It also eliminates grooving of the discs which sometimes occurs when
grinding hard ores in the regular Braun Pulverizer.
All of the claims made for this machine have our unqualified guarantee and have been
substantiated by actual tests. CAPACITY
One pound of ordinary quartz rock can be ground to 80 mesh in forty seconds or at
the rate of 90 pounds per hour. Can be instantly adjusted to pulverize to any fineness
while the machine is in operation or at rest.

THE BRAUN PULVERIZER
No. 1590
This machine has a world-wide reputation. Its increasing demand is attributed
solely to quality. In no apparatus are the requirements for efficiency and quality more
important than for the reduction of laboratory samples.
This machine will pulverize any material that can be reduced to pulp on the old style
bucking board, and will produce a finer powder in less time than any other type on the
market.
CAPACITY
The capacity of the pulverizer depends on the fineness to which the material has been
previously crushed. If the product fea into the pulverizer is 34 mesh, it will be slower than
if this product were crushed finer before being put through the machine. In several test
runs we found that if the material has been crushed to about 10 mesh, the pulverizer will
easily handle from 80 to 90 pounds per hour to 100 mesh. If it has been crushed to 34 mesh
and smaller (the majority being smaller) it will easily handle 60 pounds per hour to 100
mesh. If laige quantities are to be pulverized it will be accomplished in less time if the
product is first ground to about 10 mesh and then refed through the machine, grinding this
to 100 mesh.
This machine is fed through the spout in the door, and will take ore 34 mesh and
smaller (which product may be obtained from any of our laboratory crushers) and reduce
it altfwith one grinding to any desired mesh.

THE BRAUN PULVERIZER
NO. 1590
Cleaning. One of the most striking features in the Braun Pulverizer is the accessibility
of all the interior portions for thorough cleaning. The one objection to all mechanical
pulverizers has been the danger of salting samples. In the Braun Pulverizer this danger
is entirely eliminated as all the interior parts are either enameled or machine finished, allow¬
ing the material to be easily brushed into the pan. The manner in which the cover and door
of the machine are opened insures all of the pulp being brushed into the pan, and this
feature alone places it far in the lead of other grinders on the market.
Bearings. The bearings in this machine are babbitted and extra long. Grease cups
are furnished, and if proper attention is given to the oiling there is no danger of these bear¬

BRAUN SAMPLE GRINDERS
No. 1692
This machine fills a long felt want for a hand power laboratory grinder. It entirely
replaces the “old drudge,” the bucking board.
Like all our other machines, this grinder has been designed to meet laboratory re¬
quirements. The adjustment may be altered instantly. It is dustproof, and there is no
loss of material. The gears are enclosed, obviating all danger. The vertical shaft runs in
ball and roller-bearings, and there is little or no friction. The bucket is suspended from
two screws and fits closely, making an absolutely tight receptacle which insures the dis¬
charge of material into the pan.
The feed chamber is provided with a cover which has a small feed spout fitted with
a hinge door. This prevents the loss of any material and makes the machine absolutely
dustproof. The entire cover may be removed in a second.
CLEANING
The ease with which this machine can be cleaned will readily appeal to the operator.
The revolving disc is lowered and all portions are readily accessible for thorough cleaning.

ADVANCE DISC SAMPLE GRINDER
These machines are intended for the use of assayers who realize the importance of a
properly ground sample.
The Advance Disc Sample Grinder consists of a main frame or support to which is
secured a stationary disc. A rocker-arm, carrying a driven shaft, to one end of which is
secured a grinding disc, and having driving gears at the opposite end, is pivotally journaled
to the main frame of the machine. When in operation, the disc on the driven shaft is given
a double motion, rotating and vibrating. The oscillating or vibrating motion is created by
means of an eccentric on the driven shaft, which by rotating against a roller, which is
journaled to the main frame of the machine, causes the rocker-arm carrying the driven disc
shaft to rise and fall.
The cam or eccentric is not keyed to the disc shaft, but is slowly rotated around the
disc shaft by means of gears so as to limit the oscillating motion of the rocker arm and disc
to a contracted orbit of travel. This double motion is very destructive to the ore particles,
which are fed between the discs from a hopper leading to an opening through the stationary
disc, and not only alters the position of the rolling particles between the discs, but prevents
the discs from becoming concentrically grooved, which would occur should the disc or discs
have a rotary motion only.
The rocker-arm carrying the driven shaft and disc may be lifted or swung over, clear
of the opposing disc, to allow both discs to be cleaned of any adhering particles of any sample
previously crushed, which might otherwise “salt” the succeeding sample.

IMPROVED ORE-SAMPLE GRINDERS
NO. 1098
1598 These machines are designed for the purpose of simplifying and economiz¬
ing the grinding of ore samples. Grinder No. 2 is simple in construction, compact and ex¬
tremely durable, and is extensively used by the leading smelters and sampling works. The
hopper and grinding ring may be swung open and the cone lifted out and cleaned after the
sample has been ground, and when the grinding ring and cone are worn they may be re¬
placed by new ones without difficulty. The grinding parts are made of a hard composition
metal and are very durable.
Grinder No. 1 is a lighter machine than No. 2 and about one-half the capacity. It is
suitable for mills and sampling works of moderate capacity.
The design varies somewhat from the No. 2 machine.

WEATHERHEAD’S CRUSHER PULVERIZERS
1600 It is easy to clean, as there are no joints or corners for pulverized material to
stick in.
It revolves easier when pulverizing material than it does when empty.
It is the only hand machine that discharges the material as soon as pulverized.
The working surfaces are tempered as hard as steel can be tempered, thereby minimiz¬
ing the wear.
The machine has been in constant use for over twelve years, so that the claims for it
have been thoroughly demonstrated.
The cover of the machine is made so it can be used for a small hand mortar, the ends
of the handles being rounded to form a pestle.

AUTOMATIC PATTERN
“ A boy can make 600 cupels in an hour with the Automatic Machine.”
No. 1610
No. 1610
A careful assayer is always a partic¬
ular one, and considers a perfect cupel as
necessary for an accurate assay as a good
balance. Our cupel machines always pro-
duce perfect cupels; are simple in con-
struction and easily operated. Hand
driven cupels are never uniform either in
size or compression, and a large percent¬
age fissure or check in the muffle. The
compressing power in our cupel machines
is obtained by a series of levers which
multiply the applied power about twenty
times. The pressure is steady, and by
adjusting, different degrees of compression are obtainable. This
overcomes the difficulty found in making cupels of same
absorptive powers of different grades of bone ash, and permits
the assayer to make cupels of any density he desires, Perfect
edges and smooth faces are obtained by expelling cupel
downward.
These machines are manufactured in three different styles to suit various operators.
Their convenience and efficiency make them a necessity in every assay office.
This machine consists of a hopper to hold the moistened bone ash, and a removable
disc with a number of holes which are automatically filled and brought into position under
the plunger. To operate, the bone ash is properly moistened and placed in the hopper in
which is a small wheel with a rubber rim that keeps the material stirred up and fills the
molds. Then raise the lever handle and grasping the handle on the lower disc bring the
filled mold beneath the plunger. The downward motion of the lever handle compresses the
cupel, and by pulling the disc handle in a reverse direction to that formerly given it, the
opening in the lower disc is brought beneath the cupel, and further pressure on the lever
handleDrings a new system of levers into action expelling the cupel which may be caught in
the hand. An automatic attachment stops the disc at the proper points, ana an adjusting
device is arranged for giving different degrees of compression.
Cupels of various sizes may be made by using interchangeable discs and dies, which
are easily adjusted to the machine. Perfect edges and a homogeneous cupel are always
obtained.

STERILIZATION UNDER STEAM PRESSURE
1686 Digester or Autoclav, for sterilizing under steam pressure. The
boiler is made of extra heavy copper, tin-lined, is 24 inches deep and
11 inches in diameter, with a perforated rack inside. The lid is made
of cast brass and nickel-plated. It is made with a ground joint no
washers being necessary to make it steam-tight; it is held in position
by six screw clamps. The apparatus is tested and guaranteed to stand
pressure of 50 pounds to the square inch, is provided with a pressure
gauge, thermometer and safety valve; the latter is set at 30 pounds,
but may be increased or decreased. There is a small pet valve which
must be kept open until the steam escapes, thereby forcing all the air
out of the boiler. The base is made of sheet iron and is 8 inches high;
extreme height of the apparatus is 40 inches.

The double walls are packed with asbestos to conserve the heat, and when the door
is closed it becomes an air-tight box. Within, at the top and the bottom of the oven, are
the two heating plates. As soon as the current is turned on, these at once become hot
throughout their whole area and give a steady, measured heat to every part of the oven,
a heat that comes from above as well as below; a heat that is the same every time with the
same position of the switch, and the effect can be measured by the clock.
The electric oven can be placed where it is most convenient to reach without stooping.
In use it will not affect the temperature of the room.

ELECTROLYTIC APPARATUS
NO. 1766
GUESS-HAULTAIN ELECTROLYTIC APPARATUS
1766 The increasing demand for greater speed and more accuracy in making a large
number of assays daily has caused the development of electrolytic apparatus for use in
determining lead and copper. The Guess-Haultain apparatus can be supplied in small sets
or sets of many units without the prohibitive investment for heavy platinum electrodes.
The corrugated form of electrodes permits of minimum weight and maximum surface
and furnishes the necessary strength and rigidity.
The anodes mav be either stationary or rotating. If the latter equipment is desired,
each one is supplied with its individual motor, so that any one or all may be rotated at
pleasure. The manner of attaching the electrodes to their respective circuits is quick and
convenient. The current may be either alternating, using a rectifier, or direct or by direct
current from a battery.
Prices upon application, being somewhat dependent on market price of platinum.
In writing for information state the number of units desired and whether for battery
or power current; if for power current, state voltage, direct or alternating, giving cycle and
phase.
We are prepared to furnish special equipment to educational institutions where it
is desired to have two-unit individual cabinets for the use of the students, or a larger num¬
ber of units in cabinets, each fitted with special devices so that the current is easily con¬
trolled, and insuring accurate results.
Outfits of any number of units can be supplied.
ROTATING ANODES
To facilitate the deposition of the metal, a rotating anode has been found most effi¬
cient, reducing the time to a minimum. Our form of installing rotating anodes is dif¬
ferent from those generally in use, as we supply a separate little motor for each electrode,
so that one or more can be run at a time, which makes a more satisfactory electrolytic
outfit than where the entire row of electrodes have to revolve when one is in operation.
Price of these motors, each.$1.00

of filter press. Each plate represents one square foot of filterating area and the chamber
has a capacity of one twenty-fourth of a cubic foot. There are six chambers, so that the
exposed filtering area is six square feet with a capacity for solids of one quarter cubic
foot. It is arranged so that the filtered material may be discharged through internal ports
without exposure to air or discharged into an open trough, and it is equipped with ports
for absolute washing or extraction. There is supplied with the press, when desired, a
specially constructed Mont ej us for feeding the press, which is much more convenient
where compressed air is available.

FILTERING APPARATUS AND PUMPS
FILTERING APPARATUS, FITZGERALD’S
CONSTANT LEVEL
1878 The apparatus works the same as inverting a
flask containing the liquid to be filtered over a funnel with its
filter paper, having the opening of the flask a little below the
edge of the paper, but does the work more conveniently and
accurately. When wanted for use it is set up as illustrated,
with the lower opening about three-sixteenths of an inch below
the edge of the paper. The glass rod is pushed down until
the ground stopper closes the opening. The rubber stopper
is then removed from the side opening and the liquid to be
filtered is poured in. The glass rod is then gently raised till
enough liquid has entered the funnel to close the lower open¬
ing. At this point the stopper is replaced in the side opening
and rod raised an inch or two. The level of the liquid in the
funnel starts to recede at once, exposing the lower opening,
allowing air to enter at this point, with the consequent re¬
plenishing of the liquid to the funnel. After a filtration is
made the precipitate may be washed in like manner with
distilled water.
A great variety of work can be done by this useful little
device and it is especially valuable when, as frequently hap¬
pens, the chemist has no time to complete a filtration by hand
before leaving for home at night and can put the liquid in the
apparatus before leaving the laboratory and find it filtered next morning.

FIRE EXTINGUISHERS
No. 1956 No. 1958
“DRAGON” FIRE EXTINGUISHERS
This fire extinguisher is the latest model and is approved by the National Board of
Underwriters.
It is built of heavy Lake Superior cold-rolled copper, and is, we believe, the strongest
fire extinguisher of its type on the market.
It differs from other extinguishers in that the method of attaching the dome end bot¬
tom to the body of the shell makes the joints the strongest part of the machine. The
main sheet of the extinguisher will rupture under heavy pressure before any of the seams
will yield.
The dome and bottom are spun, not stamped; the interior is lined by immersing the
extinguisher in molten metal; all soldering is done with blow pipe, insuring even heat (no
soldering irons used); so-called wiped joints are employed; the bottle holder is of cast
brass, not wire; a rawhide gasket is used at the top and a ground joint at the hose elbow;
the stopper is of heavy lead and unbreakable.
1956 .each $15.00
“QUICKOUT” FIRE EXTINGUISHERS
The “Quickout” fire tube contains a perfectly harmless powder. Put up in red color
lithographed tin tubes, 22 inches long, 2^ inches in diameter.
All you have to do is to catch hold of the fire tube and give it a jerk from the hook.
This pulls off the cap and you flirt the powder over the fire, which will be extinguished
immediately. The heat liberates carbonic acid gas in large quantities and that smothers
the fire.
The tube may hang unused for five years, and the powder will be just as good then
as the day you put the tube in place.
1958 .each $1.50

MUFFLE FURNACES FOR COAL, COKE, OOD OR OIL
SECTIONAL FIRE CLAY TILE LINING
2118 These tile-lined furnaces are to be recommended
over anything in the market for an assay office having a
sufficient volume of work to need a large furnace. They have
been in use for a number of years, and a great many having
been sold, there is no question as to the satisfaction and
durability. As they are adaptable for any fuel, they are
suitable for any region.
The lining of these furnaces is made of tiles, rabbetted
to fit together properly, each tile being lettered and its
location shown on the blue print which we supply with the
furnace. It does not require an expert brick mason to build
these furnaces, and they can be built much more quickly
than if lined entirely with brick; furthermore, there is noth¬
ing left to the judgment of the brick mason, which might
result in a very poor furnace if he is not experienced in furnace
building.
Fig. l Fig. 2
The general arrangement of these furnaces is shown in the sectional views, Figures
1 and 2, the cuts being of the two-muffle back-fire furnace. The furnace fired from the
back, that is, the side opposite the muffle opening, is to be preferred, as the distribution of
the heat is more even. We can, however, supply them to fire from either side. The
single-muffle furnace is identical with the two-muffle furnace, except for the omission of
the lower muffle. The three-muffle furnace has the muffles arranged two
below and one above in the centre. The regular pattern of this three-muffle furnace
fires from either side, but it can also be supplied to be fired from the back.

MUFFLE FURNACES FOR COAL, COKE, WOOD OR OIL

SECTIONAL FIRE CLAY TILE LINING
The coke furnace is only made in a single muffle size. The furnaces for wood and
for oil are quite similar to the coal furnaces, proper changes being made in the fire box to
adapt them to the different fuel.
These furnaces are jacketed with red brick, and the entire furnace is securely bound
with angle irons and tie rods. We recommend that the stack be built at the side of the
furnace, as it is not best to place the heavy weight of the stack on the furnace proper.
The stack should be fined for some little distance with fire brick, for the heat in the stack
may be too high for common brick, the fire brick for the stack, and the red brick for the
stack and furnace jacket, are not supplied; but the price includes everything else necessary:
The fire clay tile lining for the furnace and for the short diagonal flue leading to the stack,
grate bars with support bars, angle irons and tie rods, fire boxes and ash pit doors, an iron
shelf with brackets (for the front of the furnace), etc.

2120 Shows our furnace for the use of graphite or other crucibles in an open furnace
where coke is available and which will prove an exceedingly satisfactory furnace.
It is lined with fire clay tile, rabbetted and lettered so that the proper location of
each piece is readily found by reference to the blue print supplied with the furnace; thus
the erection of this furnace does not require a brick mason of special skill and experience.
The design is such that the crucible is easily lifted out of the fire, on account of the
front of the furnace being very low (only 28 inches above the floor). The top of the fur¬
nace is covered with a heavy cast iron frame and the door is formed by a fire clay tile
which is clamped in a skeleton frame, hinged on the furnace top, there being no iron work
exposed to heat.
The ash pit is below the floor level, but the grate bars are high enough, so that they
can be easily raked from the under side.
The price of the furnace includes the fire clay tile and the iron work necessary to erect
the furnace, in fact, everything necessary except the red brick jacket and the fire brick for
the stack.

COLORADO MUFFLE FURNACES
FOR GAS, GASOLINE OR OIL
No. 2134
Colorado Muffle Furnaces are designed to meet the needs of a furnace simple and
practical and giving an even heat, high or low, oxidizing, or reducing, as required. They
are heated quickly, and are convenient, clean and efficient in operation. The capacity
for crucibles and scorifiers is great, as the muffles are of the square high shouldered type,
with every bit of the space available, permitting the use of larger crucibles.
The Cary Burners (for gasoline), which we recommend to heat these furnaces, have
proven themselves to be very efficient, giving high heat with a minimum expense for fuel,
on account of the perfect combustion of the gases.
Sufficient space is allowed within the furnace for proper combustion, and as the walls
are thick, the heat is given to the muffle with small loss due to radiation, etc. The furnaces
are made of strong, thoroughly burned material, and have good lasting qualities.
More specific information concerning gas or oil furnaces will be given upon request.

Fig. B
WITH MUFFLE REMOVED
TO SHOW INSIDE ARRANGEMENT
A clear idea of the construction is given by reference to Figs. A and B.
The flame enters the furnace from the back, going into the central flame channel, or
flue. The ribs of this flue deflect the heat, apportioning it so that both the back and front
of the muffle are heated evenly. The flame channel is covered, its roof protects and
supports the muffle in the center, there being another row of supports on either side. If
the flame struck the muffle directly it would De heated unequally, resulting in a tendency
to crack it, but on account of the thorough supporting and the even heating, the muffles
are very durable.
The ventilation of the muffle is under positive control, by moving the handle which
slides the damper over the special vent flue, in or out. The main draft may also be regu¬
lated by a damper. All the furnaces (except the No. 1 or Prospectors size) are provided
with a hood which prevents the escape of lead fumes into the room.

and thorough

COLORADO COMBINATION FURNACES
FOR GAS, GASOLINE, OR OIL
No. 2136 SECTIONAL VIEW
Colorado Combination Furnaces are the Colorado Muffle and Crucible Furnaces
combined, embracing the essentials and the good points of each separate furnace.
The flame enters the crucible end of the furnace; a portion of it passes up through
the crucible chamber, heating the crucibles there, but not striking them directly. This
portion and the rest of the flame then goes through into the muffle end of the furnace, and
by the time the first fusion is completed in the crucible chamber the muffle is hot enough
for scorification or cupellation, after which both ends of the furnace may be worked at the
same time.
The furnace, therefore, has a large capacity, especially as the muffle is of the square,
high shouldered shape, and all of the room within it can be utilized.
A small special flue gives a good draft through the muffle, which may be regulated by
sliding the damper in or out. The main draft may also be regulated by a damper.

COLORADO CRUCIBLE FURNACES
FOR GAS, GASOLINE OR OIL
No. 2138 TOP VIEW
Colorado Crucible Furnaces have been designed with the same care that is put upon
the muffle furnaces.
The main objection to an open fire furnace has been overcome in ours, which is espe¬
cially easy on crucibles, as the flame does not strike them directly.
The flame enters the furnace below the plate, or bottom, of the crucible chamber,
there being room around the edge to allow it to go up into the crucible chamber proper.
The crucibles are set upon this plate, and as the flame does not strike them directly, they
are heated evenly and not subjected to the strains due to unequal heating, and are, there¬
fore, much less liable to crack, causing a loss of work, with the attendant annoyance, etc.

Nob. 41 TO 46 WITH RING AND COVER REMOVED
No. 2140
The Colorado Furnaces of the following sizes are especially suited to the melting of
cyanide precipitates, bullion, brass, etc., and to the retorting of amalgam. The flame is
thrown in tangentially and swirls around the crucible instead of striking it directly, thus
heating it more evenly and prolonging its life as it is relieved of the liability of cracking
due to uneven strains.
Sizes Nos. 41, 42 and 43 are made of three parts, viz.: The lower or main body; the
ring, which, when removed, exposes the crucible down to the bilge so that it is gripped
easily with tongs and removed; and the cover.
Sizes Nos. 44, 45 and 46 are made in two pieces: The main body and the cover. Suffi¬
cient room has been allowed around the crucible for the insertion of tongs and the ready
removal of the crucible.
The crucible is set upon a replacable stool, which exposes the bottom to be heated.

HINTS FOR FURNACE AND BURNER MANAGEMENT.
The burner should fit tight against the burner boss, which should be the right size for
the burner used. The generation of gas within the burner is dependent upon heat re¬
flected against the front, but the burner must not be too hot or it will bum. A leakage
of flame between the boss and the burner will overheat the burner head.
In shutting off the burner, it is better to close the valve in the supply pipe, and not
shut the valves in the burner at all, for if the latter are closed tight, when the burner is
hot, an injury to the seats may result due to contraction in cooling. Brass is very weak,
especially when hot.
When through firing, the furnace should be shut up and allowed to cool slowly, closing
the damper in the main pipe, and putting the muffle door or cover in place. The burner
should be swung away from the burner hole or else a piece of asbestos slipped in front of it.
The reflected heat against the idle burner might burn its head; when the burner is going,
sufficient cold air and gas are drawn through the burner to keep it at a relatively low heat.

and swirls around the crucible instead of striking it directly, thus heating it more evenly
and relieving it of unnecessary strains and prolonging its life. The crucible may be re-
moved readily, ample room for tongs being allowed. The larger sizes of the furnaces
consist of three pieces. The bottom or main body; the ring, which, when removed, ex¬
poses the bilge of the crucible to facilitate gripping it with tongs; and a cover. They are
made of a mixture to stand the severe strains of expansion and contraction and are sub¬

2150 This No. 5 combination furnace was especially designed to meet the demands
of such engineers and assayers who find it advisable or necessary to complete their tests on
the property under examination. Holds five 20-gram crucibles in the crucible chamber.
The muffle will accommodate 12 or more cupels at one time.
The amount of gasoline needed to operate this furnace to its full capacity will not ex¬
ceed one-half of a gallon per hour.
One burner furnishes ample heat for melting and cupelling simultaneously. The flame
from the burner is not, as in other assay furnaces, injected against the crucibles but is in¬
jected into the crucible chamber at a point tangent to the inner circumference and impinges
on the circular wall and swirls around the crucibles. This manner of firing saves the
crucibles; as any competent assayer knows that it is very destructive to crucibles to play a
hydro-carbon flame directly upon them.
Furnace measures 14 inches outside diameter and 20 inches high over all; the crucible
chamber is 8 inches inside diameter, 6 inches high in the clear; the muffle is 3x4$£x8 inches;

ROTARY FLAME COMBINATION FURNACES
Patented April i, 1902
The illustration shows Furnace No. 40 with Cary Hydrocarbon Burner and Tank
Outfit.
These furnaces are constructed in such a manner that the muffle is placed above the
crucible compartment, and in this respect differs from our other types of combination
muffle and crucible furnaces. In this furnace a large crucible compartment is obtained, and
the different portions of this compartment are, to a limited extent, of different temperatures.
The burner hole opening of the furnace is located in the centre of one side, and the
flame from the burner is forced toward the opposite wall of the furnace where it is de¬
flected to both sides of the chamber by a brick of special shape, which forces the flame in a
rotary motion around both sides of the crucible compartment. This brick is always in the
hottest part of the flame, thus saving the fire clay lining of the furnace, and, being separate,
can easily be replaced at a slight cost.
Each cover for the crucible compartment is made in two sections, so that they may
easily be removed. The draft for cupellation is obtained through an opening about 1 }\
inches in diameter made in the jacket and lining at a point opposite the hole in the rear end
of the muffle, and the amount of air admitted to the muffle is controlled by a slide fitted to
the jacket. An opening larger than the inlet is provided just inside of the jacket and direct¬
ly over the open end of the muffle. This outlet is opened and closed by withdrawing or
inserting the fire clay muffle plug. The heat rising from the crucible chamber creates by
suction a draft through the full length of the muffle when the inlet and outlet apertures are
open, thus securing rapid cupellation. The jacket of this furnace is made of sheet iron.

L. & C. COMBINATION FURNACES
No. 2158
This furnace is intended for use with the Sunset Burner, and is mounted with a swivel
in the center, allowing it to revolve so that the burner may be inserted in the burner hole at
either end.
A dividing brick is furnished to be placed between the melting and muffle compart¬
ments, if but one is to be heated. We find, however, that in most cases sufficient heat is
obtained in the muffle by using the burner at the crucible end to make one melt, then re¬
volve the furnace and insert the burner at the other end. From then on the melting and
cupellation may be carried on at the same time without revolving the furnace. A small
trap door is placed in the bottom of the melting compartment, and in case of a spill it may
be opened, the bottom knocked out, and replaced with a mixture of fire clay and sawdust.
A great objection to nearly all types of muffle furnaces, namely, that they are poor
oxidizers, and for that reason cupellation is satisfactory in but a small part of the muffle, is
overcome in the L. & C. and Cary Furnaces by the use of our patent draft inducing at¬
tachment. This consists of a fire clay flue connecting the muffle through a hole in the end
with the pipe leading to the main flue. A damper is placed in this pipe, which may be used
to choke the draft when the buttons in the cupel are opening.
L. & C. Furnaces differ from the Cary in the fact that there is a small chamber around
the muffle, and also a smaller oxidizing bonnet. The burner hole is also shaped to permit
the use of the Sunset Burner. For these reasons it will be seen that the Cary Burner is not
entirely satisfactory when used with this type of furnace, as the flames will fire back and the
products of combustion are not carried away as they should be.

No. 8 IMPROVED SHAPE CRUCIBLE FURNACE
The interior shape of this furnace is entirely different from our other types, which
improvement consists of a contracted space near the outlet, wherein the two crucibles
nearest the outlet deflect the flame, enabling it to better perform the work before passing
out of the furnace. It can be operated with a small size Cary Burner (l^-inch), which
consumes less than one-half gallon of gasoline per hour, making it economical in operation.
It is also provided with a removable shelf, which will be found convenient when handling
hot crucibles or covers.
This type of furnace is largely used in the tin smelting industry, where it is recog-
nized as the standard for this purpose.

NON-TILTING FURNACES
2174 Pots lifted out and carried to moulds with or without “crane lift.” This
furnace is designed primarily for those who prefer to lift the crucible out with tonga, as of
the old coke method, and convey the crucible to mould by shank or crane. Sometimes it
is preferable to use a crucible which will hold a given quantity of metal for a certain casting,
therefore the makers have patented the non-tilting furnace and guarantee the same results
as obtained in the standard tilting.
DIRECTIONS
With cover swung aside fill crucible with regular charge of metal, beginning with that
which requires highest melting point, same as old style coke method. Anneal crucible
thoroughly and when pot is charged, put cover on firmly. See that burner flame is steady
and that combustion within is perfect. The furnace is a rapid melter and will produce
twice the metal of same size coke. When ready to pour, shut off air and oil or gas. Re¬
move cover by automatic lift, turn aside, and lift crucible by tongs and carry to moulds.
In order not to lose the heat in furnace, it is well to put another pot in same for annealing.

CARY HYDROCARBON BURNERS
ARRANGED FOR BURNING IN ENCLOSED CHAMBERS,
SUCH AS FURNACES, Etc.
Perfect combustion requires a mixture of carbon, hydrogen, and oxygen
in certain proportions, heated to the proper temperature. To obtain these
results it is neccessary that each individual burner may be adjusted in such
a manner that a correct mixture is made. The Cary Hydro-Carbon Burner
is the only one on the market with mechanical construction that admits of
this adjustment, and the only one that allows no air to enter the furnace
except through the mixing tube, where it is thoroughly mixed with the va¬
porized gasoline.
Owing to perfect combustion, the Cary Burner consumes more oxygen
than other burners, and therefore the products of combustion in the shape
of gases are greater. As this is the case, and as each burner is adapted in a
manner to attain the most satisfactory results with no air entering the fur¬
nace except through the burner tube, it will be seen that this burner is best
suited to furnaces having special burner holes and large chambers around
the muffle, such as the Cary Furnace. While it may burn with other types
of furnaces, it is not as satisfactory. ^
Perfect combustion means intense heat, and some users of the Cary
Burner claim to reach the melting point of platinum. The flame is clean,
gives off neither poisonous nor noxious fumes, and is almost noiseless.

CARY HYDROCARBON BURNERS
No. 2178
The difficulties encountered in generating in other burners are overcome in
this by use of a separate valve and trough. Generation is accomplished by
permitting a small quantity of gasoline to flow into this trough, and igniting;
the flame envelopes the burner, and quickly heats it to a temperature which
admits opening the main needle valve and allowing the flame to be thrown
into the furnace.
Another feature of this burner is the fact that the gasoline passes through
a filter consisting of a tube having a screen at each end, and filled with clean
gravel, to remove any solid matter which may be in the gasoline and prevent
clogging the burner face. The gasoline passes entirely around the interior of
the burner face, a feature which is found in no other assay burner except our
Sunset, and which insures entire vaporization of the fuel.
The clean flame resulting from perfect combustion does not eat away or
corrode the face of the burner. In this respect the Cary Burner is practically
indestructible.
The size of the burner is determined by the outside diameter of the mixing
tube.
FUEL CONSUMPTION
The fuel consumption of the different size Burners will vary according to
the air pressure used on the oil. When from 35 to 40 pounds pressure is used
the consumption will be as follows:
134 -inch burner, 34 gallon per hour.
l}4-inch burner, J4 gallon per hour.
1%-inch burner, % gallon per hour.
2 -inch burner, 1 gallon per hour.
234 -inch burner, 134 gallon per hour.

BURNER BOSS
This is a fire clay boss or ring, which we furnish with all the furnaces supplied by
us when it is known they are to be used with a Cary Burner. The function of this boss
is to obtain a burner opening in the furnace of the correct size for the burner employed,
and one which will have an even surface against which the burner may be adjusted. The
reason for using the following exact dimensions is that these sizes allow the greatest possible
area of the burner face to be exposed to the reflected heat from the interior of the furnace,
and yet are small enough to prevent the admission of the air to the furnace, excepting that
drawn through the mixing tube of the burner by the injected vapor.

♦For cement testing a 3-inch Cary Burner, when used in connection with a special
rotary kiln, will give the required heat (3000° F.), and gives perfect satisfaction. It is
used by several of the largest cement works in the West and delivers a product similar to
that obtained from the large kilns. These larger burners are not carried regularly in stock
but are made to order only.
LARGER SIZES
We are prepared to quote on larger sizes of Cary Burners to be used for special pur¬
poses. When writing for prices give us full particulars of your requirements.
The Cary Industrial Burner embraces all of the successful points employed in the
Carv Hydrocarbon Burner, but it has been slightly altered so that it will produce perfect
combustion in the open air.
In the Cary Industrial Burner all of the parts are made heavier and consequently
stronger, while an additional brace is placed around the mixing tube to prevent injury in
rough usage. It is very substantially made and will stand a great deal of hard work.
The mixing tube of the burner is of such shape and size that the air is drawn into it
by the jet of gas under pressure in exactly the right proportions to insure complete com¬
bustion.
The Cary Industrial Burner makes the most intense heat of any hydrocarbon burner
in the world, developing from fifty to seventy-five per cent more heat than others, and at a
less expenditure for fuel.
The greatest economy in using the Cary Industrial Burner is on objects where, with¬
out this burner, you would have to take down a machine and carry it to the forge. With
this burner you cany the forge to the work, and your fire is hotter, more intense, and under
better control than in any other forge or furnace fire.

SUNSET HYDROCARBON BURNER
NO.2182
SUNSET HYDROCARBON BURNER
This burner is constructed for those who desire an efficient yet low-priced burner.
It will be found to do entirely satisfactory work, and next to the Cary, is the best gasoline
burner on the market.
As in the Cary Burner, the gasoline is forced around the interior of the burner face,
which insures its being thoroughly vaporized before leaving the needle valve. The metal
used in its construction is a special alloy, which is auickly heated and does not chip off.
as is usually the case with other burners. With this burner a certain amount of air should
be drawn into the furnace around the burner face, as sufficient air does not enter through
the mixing tube, as in the Cary Burner. It will be seen at once that this makes it entirely
different in operation from the Cary Burner, and another difference is the fact that it may
be used with a furnace having smaller space around the muffle.
While the combustion is as nearly perfect as can be obtained with a burner where
it is impossible to adjust all parts, the flame is not as hot as that obtained with the Cary
Burner, but it will be found ample for assaying purposes.

GASOLINE BURNERS
No. 2184
2184 Challenge Hydrocarbon Burner. This burner is practically indestructible, the
main part of the burner consisting of one single copper casting. A straining and generat¬
ing chamber filled with small gravel extends entirely around and along the combustion tube
for half its length. The gasoline is admitted to this chamber at a point near the under
side of the burner and farthest from the face of the burner. There is an annular duct at
the face of the burner connected with the gravel chamber at the upper side of the burner
and having an outlet at its lowest point into the duct which leads to the jets of the burner.
This burner is provided with a sub-jet and a generating trough leading along under the
burner from the sub-jet to the face of the burner. When the burner is once heated prop¬
erly to the generating point, the sub-jet is to be closed.
Price.. $12.50
No. 2186
2186 “ Advance ” Hydrocarbon Burners. The acme of efficiency and simplicity;
one solid casting; no parts to work loose and twist out of alignment; equipped with an
auxiliary generating device; is beyond question or doubt the best assayers* burner on the
market.
The “ Advance ” Hydrocarbon Burner was designed with a view to giving the purchaser
a strong and efficient assay furnace burner of simple construction and at a low cost. It
is without a peer for assayers’ use, and has replaced many higher priced flimsily-con-
structed burners.

BRAUN GAS BURNER
No. 2188
FOR USE WITH ORDINARY ILLUMINATING OR FUEL GAS
There are many places where it is desirable to use illuminating or fuel gas in preference
to liquid fuel, and to supply this demand the Braun Gas Burner has been designed, which
permits the use of gas for assaying and melting purposes in an entirely satisfactory
manner.
The construction of the burner is such that air and gas are properly mixed in right
proportions after the recognized principles of Bunsen.
To obtain a sufficient amount of air for this burner it is necessary to employ a blower,
which may be operated by electricity or any other available power.
We furnish blowers which will supply sufficient air for from one to three burners,
that can be operated with belt power or can be attached to a small electric motor. These
require about K horse power to operate.
The simplicity of this outfit will be appreciated when it is considered that a mere
striking of a match and opening of valves controlling gas and air places the outfit in in¬
stantaneous operation.
Although this burner is described in connection with Combination Furnace No. 40,
it can be arranged to operate any of our furnaces. Best results are obtained from %-inch
gas supplyjpipe.
Weights (burner only): Net weight, 12 lbs. Shipping weight, 18 lbs.
Price (including air and gas valves).$15.00

HOT PLATES
ELECTRIC LABORATORY PLATES
These plates are specially designed and adapted for use in the laboratory, and are
extensively used by mining companies, chemical companies, and in the laboratories of
steel works and other industrial plants. They are used for heating sand baths, etc.
The surface of the plate heats to about 600° F., depending upon the watt consump¬
tion, length of time the current is turned on and the amount of work it is called upon to
perform. The plates are of cast iron with a finely polished planed surface, and are made
in various sizes, as listed below. They are equipped with the new steel-clad heating
elements, directly attached. They are light, durable and quick heating.

HYDROMETERS IN GENERAL
A Hydrometer is an instrument used to determine the relative densities of
liquids.
Pure water at a temperature of 60° F. is the standard of comparison.
A scientific Hydrometer scale uses this standard of comparison for the in¬
itial point of the scale, and graduates decimally above and below this initial
point to compare liquids heavier or lighter than water.
This scale is called the specific gravity scale and the initial point is marked
1 . 000 .
For example, a liquid whose density is 50 per cent greater than water
would read 1.500 upon such a scale, and one whose density is 25 per cent
lighter than water would read .750.
To place upon one Hydrometer, a scale covering these maximum ranges
would make the instrument (if of reasonable size) too sluggish for practical
use; hence these limits are covered upon a series of Hydrometer stems, placing
more degrees upon the less delicate and less degrees upon the more refined
ones.
Comparatively few Hydrometers are scaled with the specific gravity scale.
Most of them have arbitrary scales, note Beaum6, Brix, Balling and a
hundred minor ones.
It is fair to assume that the multiplicity of Hydrometer scales has arisen
because original investigators found that it suited their convenience to divide
the stems of their Hydrometers in other than the specific gravity divisions,
and their influence (note Brix and Balling upon sugar) has been strong enough
to continue the use of their arbitrary scales.
The chaos is caused by the fact that the originators of these arbitrary
scales left no clear and definite statement of the methods whereby they ar¬
rived at their scale values or their specific gravity equivalents.
Their general methods are known, but the niceties that constitute stand¬
ard conditions were not observed (no doubt they could not be at that time)
and to-day each civilized country possessing a Bureau of Standards gives its
own value in specific gravity degrees to the arbitrary standard Hydrometer
scales. (This is particularly noticeable in the Beaum6).
If of one of the less known scales, we find that custom has fixed upon one
value to a greater extent than upon another, we accordingly supply the
scale as the majority of interests have determined, but we do so knowing
that there are in use other arbitrary scales bearing the same name but of dif¬
ferent specific gravity value.

CHARGOMETER—SYRINGE BATTERY HYDROMETER
What is a Chargometer?
Briefly it is a gauge for determining the state of charge in storage batteries. By its
use the exact strength of batteries is known, and the inconvenience occasioned by ex¬
hausted batteries is overcome.
Its Construction
A glass tube enlarged at the upper end, to prevent the adhering of the instrument to
the sides, and also to bring to a minimum the distortion caused by reading the instru¬
ment through round glass walls. There are no rubber parts to dry up and drop out. All
parts are renewable if lost or broken.
Its Use
By inserting the pointed tube of a chargometer in the storage cell opening, withdraw¬
ing fluid by means of the bulb, the specific gravity is indicated by the hydrometer in the
cylinder.
2524 Specific gravity scale, 1150 to 1300. Best quality rubber bulb, rubber
buffer in end of cylinder to prevent breakage of hydrometer. Length over all, 19

HYGROMETERS
Various forms of this instrument have been devised for determining the
amount of moisture in the atmosphere, ascertaining the relative humidity, and
forecasting the probability of frost, but none with the same universal satisfac¬
tion (when the instrument is understood and proper observation taken) as the
form known as Mason’s Hygrometer. The construction of this instrument
consists of two thermometers as nearly alike as possible in range of scale,
mounted on either side of a block of polished wood with a cistern of water be¬
tween. The thermometer marked dry is exposed to the air, the other, marked
wet , has its bulb surrounded by a piece of silk, which passes down into the
opening in the cistern acting as a wick and keeping the bulb of the thermom¬
eter constantly moist. As evaporation causes a loss of heat, the wet bulb
thermometer will read lower than the other, provided there is any degree of
dryness in the air. When the air is very dry, the difference in their readings
will be great; if moist, the difference will be proportionately less, but if the air
is fully saturated, both thermometers will read alike as there can be no evap¬
oration.
By the use of tables, which we furnish with each Hygrometer, the point at
which the air would begin to deposit moisture, known as the dew point, and
the percentage of saturation of the air (humidity) are readily ascertained.
(No tables are required when the “Hygrodeik” is used.)
Dew is formed by the radiation of heat from the surface of trees, plants,
etc., consequently reducing the temperature of the air near the immediate sur¬
face of such objects to the point of complete saturation, causing moisture to be
deposited. The Hygrometer therefore becomes of the greatest value to the
farmer and florist, since in the hands of an intelligent observer the formation
of frost can be foretold with certainty, enabling him to take steps to prevent
damage to delicate plants exposed to the open air. If the temperature of the
air on a clear day at sundown be 50° and the reading of the wet bulb thermom¬
eter 40°, the dew point, according to the tables referred to, would be 27° and
frost would follow with certainty; but should the wet bulb thermometer stand
at 47° and the temperature of the air 50°, then the dew point would be reached
at 44° and no frost need be feared.
In the household for maintaining a degree of healthful humidity; in the
sick chamber, where by its use any degree of moisture will be indicated, in
many branches of manufactures, as cotton carding, incubating, in drying
rooms, malt houses and greenhouses, it is gradually being recognized as an in¬
dispensable instrument.

MILBURN LIGHTS
FOR CONTRACTORS, TUNNELS, MINERS, FOUNDRIES, ETC.
No. 2632 No. 2634 No. 2638
The Milburn Light is an improved gas light, generated from acetylene in so simple
and perfect a manner that, to obtain same, it is merely necessary to turn on the tap and
apply a light.
It adjusts itself immediately to any size flame, or any reasonable number of burners
used, and requires absolutely no attention until burnt out.
The apparatus mainly comprises three parts. An outer tank holding water, and an
inner receptacle holding the chemical, and a burner standpipe. The light closely re¬
sembles sunlight. It is fifteen times more powerful than coal gas, and is more penetra¬
ting and diffusive for the size of flame than any existing light.

Acetylene lamps are cleaner, more convenient, and cheaper to operate than candles or
oil lamps. Acetylene light resembles daylight and facilitates a more accurate examination
of veins and ores, especially their color. Notebooks, etc., are not soiled by grease nor the
air polluted by smoke—in fact, less oxygen is consumed by acetylene lamps than by oil or
candles. They will bum in places where candles and oil lamps go out.

BALDWIN ACETYLENE LAMPS
DESCRIPTION OF THE BALDWIN MINE LAMP
We show herewith, a sectional view of the Baldwin Mine Lamp. While at first sight
the many parts may lead you to believe that this lamp is rather complicated, a second
observation will show that but few of these various parts have to do with the actual work¬
ing of the lamp. The other parts are not subject to wear nor can they, in any manner,
get out of order. There are no springs nor regulating devices to cause trouble. Anyone
can successfully operate the Baldwin the first time they try.
Viewed as a whole, the lamp consists of four parts, a carbide container, a water-tank,
burner and a wire agitator. A pipe or tube projects from the water-tank, into the carbide
container. In this pipe there is a wire agitator. There is just enough free space between
the wire agitator and the sides of the tube to permit the proper amount of water to get to
the carbide. This wire is also used to free the tube from any stoppage or sediment which
might collect in same. This is indicated by the flame burning low. A turn or two of this
wire clears the tube and immediately the flame assumes its normal size and the lamp again
bums brightly. Sudden jars or a fall will not injure the lamp or affect the light. It will
bum perfectly, for a time, if laid on its side or even held in an inverted position.
The names of the various parts indicated by numbers above are given below.

While this lamp is fitted with a positive shut-off valve, it operates under
the well-known “Baldwin” method, which insures a steady and uniform
flame. It is the most substantial valve made, but we do not recommend
valve lamps in low mines, as the first blow against the roof will put a
valve lamp out of commission.

“How to Read a Magnifier.”
For satisfactory results magnifier should be held at about the distance from the eye
a spectacle lens is ordinarily worn. If this rule is disregarded, the size of the visual field is
limited and the marginal definition is likely to be indistinct.
2700 Magnifiers, Globe. The Globe lens is a perfect sphere, consisting of a
hollow flint glass globe, made in halves, and enclosing a solid crown
glass globe. By the principles of its construction the aberrations
are corrected to a higher degree than has heretofore been obtained
by any other construction. This lens has an optical axis in any
direction, hence the field is perfectly flat and distinct to the outer
edge; and what is true of no other lens, the field is always the
largest possible. Pocket magnifiers made on this principle are
furnished as follows:
No. 290—1-inch focus, nickel-plated brass mount, magnifying 11
diameters. $4.00
No. 291—%-inch focus, nickel-plated brass mount, magnifying 14
diameters. 5.00
No. 292—J^-inch focus, nickel-plated brass mount, magnifying 21

2704 Tripod Magnifier. This Magnifier is of sufficient power for elementary bio¬

in a mounting which screws up and down in the brass frame for focusing.

Too much emphasis can scarcely be laid upon the quality of these reading glasses.
They are unsurpassed, we believe, in optical properties, design and workmanship.
The lenses are accurately ground of clear, white optical glass and highly polished.
While giving comparatively low magnifications, they cover a wide field. Rims are
nickel-plated of sufficient width to protect the lens surfaces. The handles are of ebonized
wood.

STYLE No. 66
2720 The No. 66 microscope has proved so popular that we have improved it
to give our patrons the advantage of a larger instrument. The stage of No. 66 is now the
same size as that of No. 46, there being a free distance of 55 mm. from the optical axis to
the base of the arm.
The vulcanite covers the whole of the top of the brass stage and the edges as well.
It is vulcanized directly to the brass, which has been claimed and recognized for years as
being superior to stages where the vulcanite plates are simply screwed to the stage. This
makes a more durable stage and better finish. The iris diaphragm in the stage is operated
by a knurled ring, which can be reached from any side.
♦
Provision is made for easily attaching a substage ring for condenser when so desired.
The base and pillar are strong and rigid and are provided with inclination joint.
The tube, rack and pinion, new circular nosepiece, mirror, optical parts, etc., are the
same as used on our higher-priced instruments.

2722 An inexpensive, but exceedingly well-made instrument, especially intended
for the examination of any substances that do not require a very high power, as, for example,
starches, drugs, earths, cements and other commercial articles, such as fibers and fabrics,
meat for suspected parasites, paper-making materials, prints, etc. It will be found exceed¬
ingly satisfactory for work in elementary zoology and botany as taught in common schools
and for examination of insect and plant life. No better gift can be placed in the hands of
an inquiring boy or girl who is beginning the study of animal or plant life.
For all commercial, household or elementary school purposes this microscope affords
a wide field of usefulness and pleasure.

MICROMETERS
2724 Micrometers. For measurement by thousandths up to 1 inch. Has lock¬
nut and ratchet stop. . $6.00
In leather case. 6.50
HOW TO READ A MICROMETER
The spindle C is attached to the thimble E at the point H. The part of the spindle
which is concealed within the sleeve and thimble is threaded to fit a nut in the frame A.
The frame being held stationary, the thimble E is revolved by the thumb and finger, and
the spindle C being attached to the thimble revolves with it, and moves thru the nut in
the frame, approaching or receding from the anvil B. The article to be measured is placed
between the anvil B and the spindle C. The measurement of the opening between the
anvil B and the spindle C. The measurement of the opening between the anvil and the
spindle is shown by the lines and figures on the sleeve D and the thimble E.
The pitch of the screw threads on the concealed part of the spindle is 40 to an inch.
One complete revolution of the spindle therefore moves it longitudinally one fortieth (or
twenty-five thousandths) of an inch. The sleeve D is marked with 40 lines to the inch,
corresponding to the number of threads on the spindle. When the micrometer is closed,
the beveled edge of the thimble coincides with the line marked 0 on the sleeve, and the 0
line on the thimble agrees with the horizontal line on the sleeve. Open the micrometer
by revolving the thimble one full revolution, or until the 0 line on the thimble again coin¬
cides with the horizontal line on the sleeve; the distance between the anvil B and the spindle
C is then or (.025) of an inch, and the beveled edge of the thimble will coincide with the
second vertical line on the sleeve. Each vertical line on the sleeve indicates a distance of
A of an inch. Every fourth line is made longer than the others, and is numbered 0, 1, 2,
3, etc. Each numbered line indicates a distance of four times of an inch, or one tenth.
The beveled edge of the thimble is marked in twenty-five divisions, and every fifth
line is numbered, from 0 to 25. Rotating the thimble from one of these marks to the next
moves the spindle longitudinally ^ of twenty-five thousandths, or one thousandth of an
inch. Rotating it two divisions indicates two thousandths, etc. Twenty-five divisions
will indicate a complete revolution, .025 or 4 \ of an inch.
To read the micrometer, therefore, multiply the number of vertical divisions visible
on the sleeve by 25, and add the number of divisions on the bevel of the thimble, from 0
to the line which coincides with the horizontal line on the sleeve. For example, as the tool
is represented in the engraving, there are seven divisions visible on the sleeve. Multiply
this number by 25, and add the number of divisions shown on the bevel of the thimble, 3.
The micrometer is open one hundred and seventy-eight thousandths. (7X25 = 175-1-3 =
178.)

MICROTOMES
Automatic

Table
No. 2728
AUTOMATIC
2726 In this microtome the main supporting frame has a heavy clamp at the
back by which it is securely fastened to the laboratory table. As will be seen by the cut,
the upper part of this frame forms a support to which the two laterally swinging arms are
attached by steel pivot screws with check nuts.
The knife carrier is held by these swinging arms at their outer ends, attached thereto
by similar pivot screws with check nuts, and in order to give the proper movement, relieved
from any pressure or strain, a detachable flexible lever handle is attached to the axis
fastened to the longer arm on which the arm swings.
The extreme ends of the knife rest in the holder, and as the lever moves the swinging
arms the blade describes the flattened curve, corresponding to the double movement in
the free-hand sectioning. By this manner of holding the knife by arms which are not
parallel, the entire length of its cutting edge is utilized, insuring uniform wear and per¬
mitting the cutting of larger sections than has heretofore been possible, except by using a
very much larger blade. The swinging arms and knife holder are sufficiently rigid to avoid
any deflection of the knife in its movements, thereby assuring an absolute uniformity of
thickness in all the sections.
Price, without Freezing Attachment.$45.00
TABLE
2728 As will be seen from the engraving, this may be firmly attached by a screw-
clamp to the laboratory table or other support. The round shank of the object clamp for
paraffin blocks sets in a vertically movable socket, held by hardened steel pivot screws in
two vertically swinging arms which are similarly attached to the main frame, thus provid¬
ing a movement upon the parallelogram principle regulated by a micrometer screw with
graduated disc and index plate by which any desired thickness of sections may be cut. Glass
surface plates provide traveling ways upon which the knife slides. These are extra long,
so that the knife will not be drawn off from the ends, thereby endangering its edge.

WAGNER MOTORS
SINGLE-PHASE
A few salient points regarding these motors, and single-phase in general:
1. High starting efficiency.
2. The current demands at starting may be regulated in accordance with the actual
load requirements.
3. Minimum maintenance cost.
4. Control is simplicity itself, a double-pole switch being all that is required.
5. The motor may be operated (started and stopped) a considerable distance, a mile
or several miles, from the place of location.
6. Polyphase generation and single-phase distribution is now recognized as modern
practice.

MUFFLES
Our muffles, manufactured by the Colorado Crucible & Clay Company (for whom we
are sole agents), are the very highest standard for these goods. They are made of Colorado
Clay, (renowned throughout the world) by skilled ceramists of years of experience.
We have no hesitancy in recommending them, and will stand behind their quality to
the utmost.
In ordering, please give the designating letter and the number; and it is also wise as an
additional precaution to give the outside dimensions.
The list on the following page gives the standard sizes, and no difficulty should be had
in selecting one to meet the requirements of everyone. Besides this list, we have many
special muffles in stock. Moreover, we are glad to make special muffles according to
special ideas or requirements as reasonably and quickly as possible. In ordering such
special muffles, be careful to give complete information; not only dimensions, but the shape
of the opening into which the muffle is to fit is needed. Also give the particulars as to the
ventilating holes.
MAXIMS FOR THE CARE OF MUFFLES
1. See that the muffle has a bearing on all supports, as otherwise very disastrous
strains are put upon the muffle.
2. Muffles should be dry before being put into the furnace.
3. Considerable additional life may be gained from muffles by avoiding cold air
draughts striking the muffles, either in front or outside through the fire box.
4. The muffle should not be heated or cooled more rapidly than necessary. It is well
to shut up the furnace after the day’s work is done, allowing it to cool slowly. These pre¬
cautions are also good for the furnace.
5. If anything is spilled in the muffle, put bone ash on the spot quickly.
The Colorado Muffles will stand a great deal of abuse and radical changes in tempera¬
ture, but by avoiding them and the strains incident thereto, the life of the muffle will be
prolonged.

CENTRIFUGAL OIL TESTING APPARATUS
No. 2900
Braun’s Oil Centrifuge—For the determination of sediment and water in crude oils.
In the determination of sediment and water in crude oils, the experience of chemists through¬
out the country has demonstrated beyond a doubt, first, that a centrifugal machine is an
absolute necessity, and second, that the small hand, water or electrically driven centrifuge,
suitable for physicians’ use, is entirely inadequate and useless when a thick, viscous sub¬
stance is to be dealt with.
After a long series of experiments, in which we have made and discarded many types
of centrifuges, we have at last a machine to offer, which will meet with the approval of the
most exacting.
SPECIAL FEATURES
Roller bearings, reducing friction to a minimum, and necessitating oiling only about
once in six months.
Adjustable friction clutch, permitting a variation of speed between the limits of 1000
and 2000 revolutions per minute, while motor or shaft runs at a constant velocity.
Arrangement for maintaining speed constantly at any desired velocity.
Massive construction, first-class material and perfect balancing permit machine to be
run at high speed without vibration or danger.
Four tubes on heavy cross arms enable four determinations to be made at one time.
Tubes of a special shape, graduated in 1-10 cc. for the first cubic centimeter, and in
2-10 cc. for the next two cubic centimeters permit a rapid and accurate reading of results.
Glass tubes are arranged to be surrounded by water in aluminum shields; this acts as a
cushion and reduces the danger of breaking to a minimum.
Special arrangement for transmitting the power permits of gradually increasing the
speed from rest to the desired speed, thereby eliminating all slopping of oil out of the tubes.
The arrangement of power transmission permits the motor or shaft to be mounted
with axis in horizontal position.

CENTRIFUGAL OIL TESTING APPARATUS
No. 2902
WITH MOTOR
With this machine a complete separation of oil, water, sand and B. S. in any sample
can be effected in about fifteen minutes. Experience has shown that a tube of less capacity
than 100 cc. is not satisfactory.
The machine is made in one size only, but can be furnished mounted on base, directly
connected to any standard motor for either alternating or direct current; or, if preferred,
can be furnished with tight and loose pulleys, to be operated by belt from countershaft.

NOTES UPON THE USE AND CARE OF
PLATINUM WARE
It is important to remember that, although platinum is not oxidized in the
air at any temperature, nor attacked by any single acid, yet there are many
substances that attack and combine with it at comparatively low tempera¬
tures.
The caustic alkalies, the alkaline earths, nitrates and cyanides, and es¬
pecially the hydrates of barium and lithium, attack platinum at a red heat,
although the alkaline carbonates have no effect at the highest temperatures.
Sulphur in the absence of alkalies, has no action, but phosphorus and arsenic
attack platinum when heated with it.
Direct contact of platinum with burning charcoal should be avoided,
since the silicon reduced from the charcoal ash unites platinum, making it
brittle and liable to fracture.
Also contact with compounds of the easily reducible metals is especially
dangerous at high temperatures, as alloys with platinum having a low fusing
point are readily formed. This is especially true of lead.
Heating of platinum with spirit lamps is preferable to the use of ordinary
gas. When gas is used, care should be taken to have the supply of air suffi¬
cient to insure complete combustion, since, with the flame containing free car¬
bon, the platinum suffers deterioration by the formation of a carbide of platin¬
um, which, oxidizing later, blisters the metal. For this reason, also, the inner
cone or reducing flame should not be in contact with the metal.
The loosening effect of the Bunsen flame upon the surface of platinum ex¬
posed to its action produces the familiar gray appearance which can not be
removed except by burnishing. Platinum triangles often become gray and
very brittle from the same cause. Systematic application of moist sand to all
articles affected in this way, after use, will keep them in prime condition and
materially prolong their life, with but a trifling loss in weight.

CLEANING PLATINUM WARE
Every careful analyst of necessity uses clean utensils. A habit of clean¬
ing and polishing platinum dishes immediately after using is easily formed,
and repays the user with increased confidence in his work as well as in the pro¬
longed life of the article.
Rubbing the surface of platinum with moist sea sand (round grains only),
applied with the fingers, seryes to remove most impurities and to polish the
metal without material loss.
Fusing bisulphate of potash or borax in the dish and then boiling in water
and polishing as above with sand is recommended by Gmelin. When it is
desired to clean the outer surface of dishes in this manner, they must be
placed in dishes of sufficient size to allow the fused flux to completely envelope
the article to be cleaned.
Sodium amalgam possesses the property of wetting platinum without
amalgamating with it, even when other metals are purposely added to the
amalgam. This substance is, therefore, useful for effecting a quick and thor¬
ough cleansing of platinum. The amalgam is gently rubbed upon the metal
with a cloth and then moistened with water, which oxidizes the sodium and
leaves the mercury free to alloy with foreign metals. The mercury is then
wiped off and the dish cleaned and polished with sand, as above described.
If the existence of a base metal alloyed with the platinum is suspected, im¬
merse the article in question first in boiling HC1 for a few minutes, then, after
thorough rinsing with clean water, immerse in boiling HN0 8 acid free from
chlorine.
If the dish is unaffected in weight or appearance, and the acid baths fail
to give reaction for the base metals, their absence in appreciable quanties is
assured.
We handle only the Platinum Ware of the best manufacturers.
The purity is guaranteed and the shapes are of the latest designs.
The Crucibles and Dishes are hammered. Special apparatus is made to
order.
Weights given are approximate only.
List prices are not given on account of the fluctuation in the market, but

3116 The plates illustrated above are for use with our furnaces when it is desired
to use an iron retort for distilling mercury. Everyone who has done this work has noticed
the difficulty experienced in propping up the retort in such a manner that it will remain in a
stable condition, and yet allow the bottom to receive the greatest amount of heat.
As will be seen in the illustration, with the plate in position in the furnace, the greatest
possible amount of surface is exposed to the action of heat, and this causes distillation to
proceed with great rapidity. These plates are made of the best cast iron and well finished
m several styles and sizes to fit our various furnaces; they will be found of great use in an
assay laboratory.

CHEMISTS' SLIDE RULES
No. 3164
The performance of multiplication and division was greatly simplified by the intro¬
duction of logarithms by Briggs. It was attempted as far back as the beginning of the 17th
century to represent logarithms graphically, and this attempt led to the invention of the
slide rule. The logarithmic method transforms multiplication into addition and division
into subtraction.
It is the purpose of this instrument to effect a reduction of the time required for the
calculation of chemical analysis to a few seconds, and at the same time to increase the
accuracy of the results. The calculations for which it serves include multiplication, divis¬
ion, and the determination of various powers of numbers. The extraction of roots is also
possible, but being somewhat more complicated and not being required in a chemists’
ordinary work, omitted from this pamphlet.
CALCULATION OF ANALYSIS
This involves the use of proportion and may be expressed by the equation —g——
percentage, in which F is the factor, P is the amount of substance found, and S is the quantity
taken. As the factors are constant numbers they have a fixed place on the slide rule,
and are indicated by a mark on the scale. Certain elements are determined in different
forms of combination and have consequently different factors. The marks corresponding
to the factors are placed above the logarithmic divisions in order not to cause confusion.
In the calculation the runner must always be employed. In the case of elements or atomic
groups, which are always determined in one and the same form of combination, for example
carbon as CO 2 , hydrogen as H 2 O, there is entered in large letters along with the factor the
symbol of the element or atomic group. In the case of elements which may be determined
in different forms of combination the symbols of these different forms are expressed by
smaller letters. The fact that the factors appear distributed both on the rule and on the
slide promotes clearness and facilitates the readings.

SILICA WARE
The manufacture of articles of fused silica or quartz has engaged the
attention of many experimental workers during the past few years, owing
to the remarkable properties possessed by the material and the possibility
of utilizing it for scientific and technical purposes, for which platinum or
similar costly materials have only been available.
Vitreosil is unaffected by acids with the exception of hydrofluoric, and
at high temperatures phosphoric. The action of phosphoric acid on silica
only commences above 400° C., so that for all ordinary purposes it can be
safely used with this acid.
Sulphuric, nitric, and hydrochloric acids, or a mixture of acids, such as
aqua-regia, have absolutely no action on the material.
As an electrical insulator vitreosil is superior to glass, porcelain, and
similar materials, the resistance decreasing much more slowly with rise of
temperature.
It also possesses the further advantage that moisture does not condense
on its surface, and in consequence the surface leakage is much smaller than
is the case with glass and materials of a ceramic nature.
Pure fused silica ware possesses the following valuable properties:
It is very refractory, melting above 1500° C.
It possesses a low coefficient of expansion, about ^th of that of glass,
and is therefore unaffected by sudden and extreme changes of temperature.
It is not attacked by acids (excepting hydrofluoric).
It has high electrical insulating properties, which are retained to a large
degree even at high temperatures.
Quotations for any special sizes and shapes will be given on application.

THE RALSTON NEW-PROCESS WATER STILL
3330 Is a device for purifying water by distillation and is intended for operation
upon the kitchen stove or a small gas burner. You don’t have to learn to run it because
there is nothing to run. Fill it to the proper level with water and place it over any heating
apparatus and it will distill at least one quart per hour. Under similar conditions of opera¬
tion, we guarantee it to furnish a larger amount of pure water than any other still made.
Price. $12.00
3332 Stills. For making distilled water by steam heat. Made of heavy copper with

Success in operating an incubator depends more upon the accuracy of the thermometer
and the proper control of temperature than upon any other feature. Thermometers are
scientific instruments, and are accurate or inaccurate, reliable or unreliable, according to the
intelligence and honesty of the manufacturer. The qualities which count most for accuracy
and reliability are hidden to the eye, and the lack of these qualities is not apparent.
It is not a well-known fact, but nevertheless true, that glass shrinks with age, after
extreme heating. This shrinkage is a factor of the most vital importance in the permanent
accuracy of a thermometer.

3590 Tongs, Scorifier. This is a decided improvement in tongs for scorifiers, roast¬
ing dishes, etc. It is made in such a manner that one pair of tongs will
handle all sizes of scorifiers and roasting dishes from 1 to 6 inches. They
are made in the same manner as an ordinary cupel tong, but differ from the
old style scorifier tong in that they grasp the scorifier from above, holding
it in such a manner that there is no danger of its slipping. As they are
applied from above, it is possible to remove a scorifier or roasting dish from
the back of the muffle without disturbing those in front of it. This also
permits the ready change in position of either scorifiers or roasting dishes,
and one side of the tip is shaped in such a manner that the contents of the
vessel may be poured through it without releasing the grip of the tongs.
We believe they will be found extremely convenient in muffle work, and
will replace several sizes of tongs always required for this purpose.

Depth.11-13 in.
Length of. Sight Arm when opened . 5H in.

This instrument combines the useful
features of Abney Level, Prismatic Com¬
pass, and Clinometer. Designed by a min¬
ing engineer of practical experience in the
use and possible application of the various
forms of instruments intended for pre¬
liminary survey.
The distinguishing feature of the in¬
strument is that, owing to its novel con¬
struction, only one observation is necessary
to obtain both the magnetic bearing and the
No. 3610
vertical angle of any distant point. It is also
No. 3612
specially adapted for use in difficult positions, such as are
always liable to occur in filling in the rougher details in a
mining survey. For rapid topographical work and working
in constrained positions, the fact that half the labor is saved
should be of interest to those who have to use this class of
instrument.
Another important point is that its efficiency is not
determined by the length of the diameter of the compass, as
is the case with the ordinary prismatic compass. With
even a small instrument the same length of sight is obtained
as would be obtained with a 6 or 7-inch prismatic compass.
As a thoroughly serviceable instrument it is worthy of
special notice.
It is not a complicated delicate instrument liable to
derangement or deterioration.
There are no reflectors or mirrors used other than the
prism, which is protected and fastened in a secure manner.

USED ON THE TRIPOD FOR VERTICAL ANGLES
While the transit is designed to be used principally as a hand instrument, it is some¬
times desirable to utilize the advantages of a fixed support and an attachment is furnished
which permits the operator to use for this purpose the light telescoping camera tripod
which most engineers include in their traveling equipment. The above illustration shows
the instrument mounted on such a tripod and tilted over so that it may be used either as a
level or for taking vertical angles.

DESERT WATER BAGS
Desert water bags are now regarded as indis¬
pensable by thousands of miners, prospectors, farmers,
sheep and cattle range/nen, campers, motor-tourists,
boatmen, vineyard and orchard hands, millmen, con¬
struction crews, hunters, surveyors, timbermen, R. R.
section men, etc., etc., also for household use.
A specialty of recognized superior merit.
If you have used a desert water bag you know the
exceptional worth of them, and would not deprive your¬
self of the luxury or satisfaction of enjoying a cool
refreshing drink of good water, at any time and any
place that your thirsty desire may demand it: but if
you have not as yet used one, let us tell you about it.
All desert bags are guaranteed.
They are durable, portable water coolers and con¬
tainers that keep water cool and palatable for several
days, even when exposed to a blazing mid-summer sun,
without the use of (unhealthy) ice.
Cooled by the air—the warm properties are drawn
to the outer surface by capillary attraction and evaporate.
No other water carrier has the same merits; they
cannot be broken, will stand rough handling, are very
handy when filled and can be folded when empty.
The material is pure (imported) flax woven into a
durable fabric especially for Desert water bags.
The side and bottom seams are double-
stitched and the seams are on the inside,
entirely protected—outside seams are not safe
or practicable.
At the top (inside) is a brace or spreader
made of strong, flexible water-reed—cheaper
constructed bags do not have this—it is very
essential.
The sanitary, strong white-enameled vitreous
spout (and the secure way it is bound in) is a
decided improvement and unequaled.
This is the only brand that offers you a
complete assortment—four sizes and two
styles in the two larger sizes.

bag. Easy to fill, easy to handle, easy to cleanse
(but seldom necessary), and they are worth to
anybody many times the moderate price.
Hang one on the harness of a field
team, on a wagon, or harvesting machine,
on an automobile, riding or pack-saddle,
on a fence, on a tree—anywhere in the
open air.

Capillary attraction and evaporation do the work.
Water in these bags will become very cool and remain
cold, especially when hanging on a machine exposed to
the intense draught of air created by speed.
Auto-motor bags are usually hung at the left of
front seat (outside). When empty can be folded; very
convenient and there is no water container that can take
their place; for radiator supply and drinking purposes.

THE « QUICK-HOT ” ELECTRIC LIQUID HEATER
The engraving shows the “Quick-Hot” in a glass of water be¬
fore turning on the switch.
The “Quick-Hot” Electric Liquid Heater is a handy little device
beautifully finished in nickel, six inches long, weighing only ten ounces.
It may be easily carried in the pocket.
When the plug is screwed into an ordinary lighting socket it is
ready for use, using either direct or alternating current.
The current does not come in contact with the liquid.
Liquids may be boiled in an ordinary drinking glass without
breaking.
It is made of absolutely the best material that money can buy
and is guaranteed against defects in material and workmanship for six
months. Properly used in accordance with directions, it should last a
life-time. As the heater is placed in the liquid, all heat generated
must be utilized, hence it is very economical. Contrast the method
with the old way of heating from the outside. Its shape renders it easy to clean. It is
as cleanly as a spoon.

WAY’S POCKET SMELTERS
TESTING ORES
The basis of the process is a small slotted
tablet the size of an ordinary playing domino,
which serves as fuel, furnace and crucible. In
composition, the smelter tablet is carbon, with
other reducing agents and fluxes in just the
proper proportion to free the metals from their
base associations and yet not fuse all into an
alloy as in blow piping or fire methods. As a
result, several different metals are often brought
down and detected in one operation, impossible
in any other method.

JOHNSON RAPID ZINC SHAVING LATHES
(Patented)
No. 3880
The experience gained in this work, together with some of the problems connected
with the rapid and economical production of the highest grade of zinc shavings for cyanide
work has resulted in the production of a machine that most fully answers all requirements
and is now in use in some of the largest mills in the country.
The development of this new and successful machine has been based on the experience
of many months spent in the production of zinc shavings for the market.
The lathe, as shown in the engraving, is of the type in which the shavings are cut from
commercial sheet zinc, taking sheets 36 inches in width, which are wound on an arbor
under pressure, the shavings being cut by a side tool fed automatically.
This process is not new, and is sometimes used by adapting an ordinary engine lathe
to the service, but at best this is makeshift, as compared with a properly designed machine
made for this purpose especially. For instance, the tool post arrangements are not suit¬
able for attaching the pressure winding device; also the heat generated by the cutting
expands the arbor, and if not attended to is likely to destroy the center. Again, there
bemg no provision in the construction of the ordinary lathe for a clear fall for the shavings
from the arbor, they are apt to become tangled or wound again, thus causing frequent
stoppage.
THE WATER COOLING DEVICE
This important feature is worked out in a very simple and effective manner, the
arrangement requiring no stuffing boxes and no parts subject to’wear, and having capac¬
ity to maintain the arbor in a perfectly cool condition. This prevents the zinc from
becoming heated, so as to produce a poor quality of shavings.
Among the advantages of this lathe we may note:
1. The use of plain commercial sheet zinc.
2. The exceedingly small percentage of waste.
3. The uniformity of product which can be maintained indefinitely.
4. The approved quality and strength of shavings produced, owing to the perfect
cooling arrangements.
5. And last, but not least, the large capacity, the product per day of nine hours
being from eight to nine hundred pounds of shavings cut to thickness of two and a half
thousandths of an inch.

HAMPTON IMPROVED ZINC LATHES
No. 3
Nos. 3882-3884
The working parts of No. 3 Lathe are on the front part of the machine, enabling
the .cutting tool to be easily adjusted. The mandrel is 6 inches in diameter, cast
with a (hollow center, allowing a free circulation of fair, preventing Ithe zinc from over¬
heating. The shavings, when cut, fall by gravity from the cutting tool^to the floor. The
machine is designed to cut three (3) thicknesses of shavings, 500,800 and 1600 to the inch.
This is accomplished by adjusting the eccentric so that the pawl will take 1,2 or 3 notches
in the ratchet wheel.
Capacity, 150 pounds shavings, 8 hours. Height to center of mandrel, 36 inches.
Speed, 120 revolutions per minute. Size of pulleys, 10 x 4-inch face. Size of zinc
sheets, 18 x 84 inches. Floor space, 25 x 45 inches.

DIRECTIONS FOR INSTALLING AND OPERATING THEJHAMPTON IMPROVED
ZINC LATHE
Upon receipt of Lathe, unpack and attach legs (which in case of No. 3 Lathe are shipped
in separate package) to the bed plate of Lathe by inserting 4 draw bolts through the legs and
into the bed plate.
Fasten legs to floor, which should be rigid and as free from vibration as possible.
Lathe should be set so belt will pull from side, and a good length of belt should be used.
The Lathe should be elevated so the shavings will have a vertical drop of about 6 feet;
in other words, set the Lathe on the second floor, or platform, and cut a hole for shavings
to drop to receptacle below. This weight of shavings will prevent them from winding around
the mandril.
After the Lathe is in position and ready to run, thoroughly oil and allow same to run
for a short time before winding on supply of zinc.
When Lathe is in good running order and well cleaned, wrap a piece of heavy paper
around the mandril and insert the first sheet of zinc in slot, winding it tightly, and just before
the end of sheet is reached insert another sheet under the end of the first, continuing this
until 8 or 9 sheets have been placed on the mandril. Hold zinc in place by binding with two
(2) pieces of wire.
The machine is now ready to operate, and care should be taken not to allow the cutting
tool to come in contact with the mandril. If the lathe chatters, the power should at once
be turned off and cutting tool re-ground. One or more tools should be ground and kept
ready to take the place of a dull one.
After loading the mandril, be sure and set the safety spring at the left-hand side of ma¬
chine so the trip will throw the pawl out of the ratchet wheel and prevent the tool from cut¬
ting into the flange at end of mandril.
Be careful and grind the cutting tools on same angles as those furnished with machine.
Do not let your machinist experiment with the Lathe, with a view of improving same, as we
have already done this; and as zinc is very hard to turn into shavings, we believe the ma¬
chine, as now constructed, is as good as a zinc lathe can be made.

SUMMARY OF MINERAL COLLECTIONS
The following summary is intended to list the different mineral collections which we
offer for sale. It does not cover all of the collections which we prepare; but should enable
the purchaser to determine more readily what collection is best suited to his (or her) needs
than would be possible without hunting through our numerous catalogues in which most
of the collections are described in detail.
Any form of mounting that is desired can be used with any of the collections; and the
price will vary accordingly. If the method described is not suitable we will submit es¬
timates for any other preferred. We recommend our improved tray for collections kept
in table cases or drawers; as being cheaper than wooden blocks, and at the same time being
a very neat method of display, the label always being in sight without the necessity of
removing the specimen.

USEFUL INFORMATION
HELP IN CASE OF ACCIDENTS
Drowning. 1 . Loosen clothing, if any.
2. Empty lungs of water by laying body on its stomach, and lifting it by the middle
so that the head hangs down. Jerk the body a few times.
3. Pull tongue forward, using handkerchief, or pin with string, if necessary.
4. Imitate motion of respiration by alternately compressing and expanding the lower
ribs, about twenty times a minute. Alternately raising and lowering the arms from the
sides up above the head will stimulate the action of the lungs. Let it be done gently but
persistently.
5. Apply warmth and friction to extremities.
6. By holding tongue forward, closing the nostrils, and pressing the “Adam’s apple”
back (so as to close entrance to stomach), direct inflation may be tried. Take a deep
breath and breathe it forcibly into the mouth of patient, compress the chest to expel the
air, and repeat the operation.
7. Don’t give up! People have been saved after hours of patient, vigorous effort.
8. When breathing begins, get patient into a warm bed, give warm drinks, or spirits
in teaspoonfuls, fresh air and quiet.
Bums and Scalds. Cover with cooking soda and lay wet cloths over it. Whites of
eggs and olive oil. Olive oil or linseed oil, plain, or mixed with chalk or whiting. Sweet
or olive oil and lime water.
Lightning. Dash cold water over a person struck.
Sunstroke. Loosen clothing. Get patient into shade and apply ice-cold water to
head. Keep head in elevated position.
Mad Dog or Snake Bite. Tie cord tight above wound. Suck the wound and cau¬
terize with caustic or white-hot iron at once, or cut out adjoining parts with a sharp knife.
Give stimulants, as whiskey, brandy, etc.
Stings of Venomous Insects, etc. Apply weak ammonia, oil, salt water, or iodine.
Fainting. Place flat on back; allow fresh air and sprinkle with water. Place head
lower than rest of body.
Tests of Death. Hold mirror to mouth. If living, moisture will gather. Push pin
into flesh. If dead, the hole will remain, if alive, it will close up. Place fingers in front of
a strong light, if alive, they will appear red; if dead, black or dark. If a person is dead
decomposition is almost sure to set in.

ANTIDOTES FOR POISONS
First. —Send for a physician.
Second. —Induce vomiting, by tickling throat with feather or finger; drinking hot water
or strong mustard and water. Swallow sweet oil or whites of eggs.
Acids are antidotes for Alkalies, and vice versa.
Acids—Muriatic, Oxalic, Acetic, Sulphuric (Oil of Vitriol), Nitric, (Aqua Fortis).
Soap-suds, magnesia, lime-water.
Prussic Acid. Ammonia in water; dash water in face; give solution cobalt nitrate.
Carbolic Acid. Flour and water, mucilaginous drinks.
Alkalies—Potash, Lye, Hartshorn, Ammonia. Use vinegar or lemon juice in water.
Arsenic—Rat Poison, Paris Green. Use milk, raw eggs, sweet oil, lime-water, flour
and water.
Bug Poison—Lead, Saltpetre, Corrosive Sublimate, Sugar of Lead, Blue Vitriol. Use
white of eggs or milk in large quantities.
Chloroform—Chloral, Ether. Dash cold water on head and chest; artificial respira¬
tion.
Carbonate of Soda—Copperas, Cobalt. Use soap-suds and mucilaginous drinks.
Iodine—Antimony, Tartar Emetic. Use starch and water astringent infusions; strong
tea.
Mercury and its Salts. Use whites of eggs, milk mucilages.
Opium—Morphine, Laudanum, Paregoric, Soothing Powders or Syrups. Use strong
coffee, hot bath; keep awake and moving at any cost.
ANTIDOTES FOR CYANIDE POISONING
All Cyanides are deadly poisons, but the aqueous solutions used in practice are so dilute
that there is little or no danger from the prussic acid evolved from them if the buildings are
properly ventilated.
Acids react on Cyanides, liberating Prussic Acid gas 2 which causes almost instant death
when inhaled in a pure state. When diluted with air, it causes faintness, dizziness and a
depressing frontal headache.
Even very dilute solutions of Cyanide are poisonous when taken internally, and, when
they come in contact with the skin, produce in some persons an eruption of painful red boils.
In cases where the hands and arms must be brought into contact with the solutions, rubber
gloves, reaching over the elbows, should be provided for the workmen. Kaffir workmen
are said to suffer no inconvenience whatsoever from the contact of their skin with Cyanide
solutions.
If the poisoning is the result of inhaling Prussic Acid gas, it is advisable to make the
patient inhale a small quantity of chlorine gas, ammonia or ether. The chlorine gas can be
quickly made and applied by sprinkling a httle bleaching powder on a piece of flannel
moistened with Acetic Acid, ana then holding the flannel to the nostrils of the patient.
Emergency Treatment In Cyanide Poisoning
This remedy consists, first of grins, of Ferrous Sulphate, dissolved in 30 cc. of
water; second, IK grms. of Caustic Soda dissolved in 300cc. of water; third, two grms. of
magnesia. The first and second are to be kept in hermetically sealed bottles.
These three remedies, with a rubber stomach tube and a mouth gag, should be kept in
a tin case 5 inches in diameter, and 7 inches high. There should also be a filtering shelf of
finely perforated metal. The case serves as a vessel for the mixture for its ready use, and
its cases should be in numerous handy places.
Everything Depends Upon Prompt Action
The bottles containing the antidotes can be broken over the filter shelf and emptied
into the tin case, the shelf excluding any broken glass. The magnesia is added and the
mixture given the patient as soon as possible. If already unconscious, the gag is put in the
mouth, the stomach tube inserted and the mixture poured into the stomach.
Before or after the dose the stomach tube may be inserted and about half a pint of
water poured down and then syphoned out by lowering the end of the tube. The stomach
should be thoroughly washed out and vomiting induced either by mustard or by tickling the
throat with a feather, should the tube not be at hand.
As soon as the antidote has been given and the tube withdrawn artificial respiration
should be resorted to as much as in the case of partial drowning or suffocation.
For skin trouble, cuts and bruises, bathe with hydrogen peroxide, and cover with vas¬
eline.

LINEAR MEASURE, U. S. STANDARD
The standard unit of the United States and British linear measure is the yard. It
was intended to be exactly the same for both countries, but in reality the United States
yard exceeds the British standard by . 00087 inch. The actual standard of length for the
United States is a brass scale 82 inches long prepared for the Coast Survey ana deposited
in the office of weights and measures at the U. S. Treasury Department, Washington.
The yard is between the 27th and 63d inches of this scale. The temperature at which this
scale is designed to be standard, and at which it is used in the U. S. Coast Survey, is 62°
Fahrenheit.

USEFUL INFORMATION
RULES FOR CALCULATING THE SPEED OF PULLEYS
The diameter of the driven being given, to find its number of revolutions: Rule
— Multiply the diameter of the driver by the number of revolutions and divide by the
diameter of the driven; the quotient will be the number of revolutions of the driven.
The diameter and revolutions of the driver being given, to find the diameter of the
driven that shall make any given number of revolutions in the same time: Rule — Mul¬
tiply the diameter of the driver by its number of revolutions and divide the product by
the number of revolutions at which the driver is to run; the quotient will be the diameter.
To ascertain the size of the driver: Rule — Multiplv the diameter of the driven
by the number of revolutions you wish to make and divide the product by the revolutions
of the driver; the quotient will be the diameter of the driver.
In ordering pulleys, give first the diameter, then the face, exact bore, whether key
seated or set screwed, and whether flat face for shifting belt or crowning for non-shifting
belt.
HOW TO ASCERTAIN HORSE POWER OF BOILERS
Standard adopted by American Society of Mechanical Engineers is 30 pounds of
water evaporated into dry steam per hour from temperature of feed water 100° Fahren¬
heit, into steam of 70 pounds pressure.
Compound engines will develop a horsepower on 15 pounds of water.
Single condensing engine will develop a horsepower on 18 to 22 pounds of water.
Automatic non-condensing engines will develop a horsepower on 28 to 32 pounds
of water.
Slide-valve throttle-governing engines will develop a horsepower on 40 to 60 pounds
of water.
STEAM MEMORANDA
A cubic inch of water evaporated under ordinary atmospheric pressure is converted
into one cubic foot of steam (approximately).
The specific gravity of steam (at atmospheric pressure) is .411 that of air at 34° Fah¬
renheit, and .0006 that of water at same temperature.
27.222 cubic feet of steam weigh one pound; 13.817 cubic feet of air weigh one pound.
Locomotives average a consumption of 3,000 gallons of water per 100 miles run.
The best designed boilers, well set, with good draft, and skillful firing, will evaporate
from 7 to 10 pounds of water per pound of first-class coal.
On one square foot of grate can be burned on an average from 10 to 12 pounds of
hard coal, or 18 to 20 pounds of soft coal, per hour, with natural draft. With forced
draft nearly double these amounts can be burned.
Steam engines, in economy, vary from 14 to 60 pounds of feed water, and from
to 7 pounds of coal per hour per indicated horsepower.
Condensing engines require from 20 to 30 gallons of water, at an average low tem¬
perature, to condense the steam represented by every gallon of water evaporated in the
boilers supplying the engines — approximately for most engines, we say, from 1 to 1J^
gallons condensing water per minute, per indicated horsepower.
WATER
Note. —These figures are all for water at its maximum density, that is, at a temperature
of 39.2° Fahrenheit.
1 cubic foot of water = 62.425 pounds, =28.3153 kilos, =7.48 gallons.
1 cubic inch of water=0.036125 pounds, =252.88 grains, = 16.386 grams.
1 ton of water=32.038 cubic feet, =239.665 gallons.
1 pound of water=0.016019 cubic foot, =0.47933 quart, =27.681 cubic inches, =0.45359
liter.
1 gallon of water=8.3448 pounds.
1 cubic meter of water=2204.6 pounds.
1 kilo of water, or 1 liter = 2.2046 pounds, =0.035317 cubic foot, =61.027 cubic inches, =
1.0567 quarts.
1 cubic centimeter of water = 1 gram, = 15.432 grains.

USEFUL INFORMATION
Rust-Joint Cement —(Quickly setting.)— 1 sal-ammoniac in powder (by weight),
2 flour of sulphur, 80 iron borings made to a paste with water.
Rust-Joint.— (Slowly setting.)—2 sal-ammoniac, 1 flour of sulphur, 200 iron borings.
The latter cement is the best if the joint is not required for immediate use.
Case-Hardening. —Place horn, hoof, bone-dust, or shreds of leather, together with
the article to be case-hardened, in an iron box subject to a blood-red heat, then immerse
the article in cold water.
Case-Hardening with Prussiate of Potash. —Heat the article after polishing, to a
bright red, rub the surface over with prussiate of potash; allow it to cool to dull red and
immerse it in water.
Case-Hardening Mixtures. —3 prussiate of potash, 1 sal-ammoniac. Or, 1 prussiate
of potash, 2 sal-ammoniac, 2 bone-dust.
Glue to Resist Moisture.— 1 pound of glue melted in 2 quarts of skim milk.
Marine Glue. —1 of India rubber, 12 of mineral naphtha or coal tar. Heat gently,
mix, and add 20 of powdered shellac. Pour out on a slab to cool. When used, to be
heated to about 250 degrees.
Glue Cement to Resist Moisture.—1 glue, 1 black rosin, 34 red ochre. Mix with least
possible quantity of water. Or, 4 of glue, or 1 oxide of iron, 1 of boiled oil (by weight).
To Remove Rust from Steel. —Steel which has been rusted can be cleaned by brushing
with a paste compound of 34 ounce cyanide potassium, ounce castile soap, 1 ounce
whiting, and water sufficient to form a paste. The steel should be washed with a solution
of 34 ounce cyanide potassium in 2 ounces water.
To Preserve Steel from Rust. —1 caoutchouc, 1*6 turpentine. Dissolve with a gentle
heat, then add 8 parts boiled oil. Mix by bringing them to the heat of boiled water; apply
to the steel with a brush, in the way of varnish. It may be removed with turpentine.
To Clean Brass.—1 roche alum and 16 water. The articles to be cleaned must be
made warm, then rubbed with the above mixture, and finished with fine tripoli.
Cement to Resist Fire and Water and Harden Quickly. —Two parts finely sifted
unoxidized iron filings; one part perfectly dry, finely powdered loam. Knead the mixture
with strong vinegar, into a homogeneous plastic mass, to be used as soon as made.
For Turned and Bored Joints. —One part white lead, one part red lead. Mix with
boiled linseed oil to the proper consistency.
For Stopping Joints, etc.— White lead in oil, mixed with enough white sand to make a
stiff paste. This grows hard by exposure, and resists heat, cold and water.
Glycerine Cement. —A valuable cement for general use, stopping leaks in tanks, join¬
ing chemical apparatus, such as glass and brass; in fact, closing cracks and stopping leaks
in almost everything, may be made by mixing commercial glycerine and litharge to the
consistency of dough. It may be somewhat improved by using Portland cement and
litharge, equal parts, when the joints or cracks are large.
Eighty parts of sifted cast iron turning, two parts of powdered sal-ammoniac, and
one part sulphur, made into a thick paste with water and mixed fresh for use, makes a
good cement for stopping holes in castings.
Asbestos is one flexible substance that electricity will not bum.
Wood ashes can be used to assist in keeping amalgamated table plates in good working
condition where the mill is not run nights. After shutting off the power at night and brush¬
ing up the plates, wood ashes freely sprinkled over them, and wet to form a paste, can be
left on them till morning. The potash of the wood ashes cleans the plates of all grease and
tends to soften and liven up the amalgam.

To compute the circumference of a diameter greater than any in the above table:
Rule. —Divide the dimension by 2, 3, 4, etc., if practicable, until it is reduced to a
diameter to be found in table. Take the tabular circumference of this diameter, multiply
it by 2, 3, 4, etc., according as it was divided, and the product will be the circumference
required.
Example.—What is the circumference of a diameter of 125? 125-s-5=25. Tabular
circumference of 25=78.54; 78.54X5=392.7, circumference required.

WHY ONE OUNCE OF FINE GOLD IS WORTH $ 20.67
One dollar in gold coin weighs.25.8 grains Troy
Ten per cent, is alloy (copper). 2.58 g rains Troy
Therefore the weight of pure gold in a gold dollar is.23.22 grains Troy
There are 480 grains in a Troy ounce. Therefore 480-^23.22 = 20.67, or the value
per Troy^ounce is $20.67.
As an example: $800.00 in gold coin weighs 43 ozs. Troy; 90 per cent, is fine gold,
or 38.7 ounces; $800.00 divided by 38.7 gives a value of $20.67 per ounce.

REFERENCE TABLES
TABLE FOR ESTIMATING THE VALUE OF SILVER PER TROY OUNCE AT
DIFFERENT DEGREES OF FINENESS, BASED $ 0.50 PER OUNCE 1000 FINE.
U. S. Currency.
To find the present market value of silver at any given time, add 2% for every lc
above 50c. Example: To estimate the value of 1 ounce of silver 750 fine, presuming the
market value of silver is 63c. per ounce for silver 1000 fine, which is 13 cents, or 26% above
the computed value in table below, thus: One ounce of silver 750 fine is worth 37J£c+26%
= s 47J<£c.

USEFUL INFORMATION
WATER.
Doubling the diameter of a pipe increases its capacity four times. Friction of liquids
in pipes increases as the square of the velocity.
To find the pressure in pounds per square inch of a column of water, multiply the
height of the column in feet by .434. Approximately, we say that every foot elevation
is equal to 14 pound pressure per square inch; this allows for ordinary friction.
To find the diameter of a pump cylinder to remove a given quantity of water per min¬
ute (100 feet of piston being the standard of speed), divide the number of gallons by 4,
then extract the square root, and the product will be the diameter in inches of the pump
cylinder.
To find quantity of water elevated in one minute, running at 100 feet of piston speed
per minute, square the diameter of the water cylinder in inches, and multiply oy 4.
Example—-Capacity of a 5-inch cylinder is desired. The square of the diameter
(5 inches) is 25, which, multiplied by 4, gives 100, the number of gallons per minute (ap¬
proximately).
To find the horsepower necessary to elevate water to a given height, multiply the
weight of the water elevated per minute in pounds by the height in feet, and divide the
product by 33,000 (an allowance should be added for water friction, and a further allow¬
ance for loss in steam cylinder, say from 20 to 30 per cent).
The area of the steam piston, multiplied by the steam pressure, gives the total amount
of pressure that can be exerted. The area of the water piston, multiplied by the pressure
of water per square inch, gives the resistance. A margin must be made between the
power ana the resistance to move the pistons at the required speed, say from 20 to 40
per cent, according to speed and other conditions.
To find the capacity of a cylinder in gallons, multiply the area in inches by the length
of stroke in inches, will give the total number of cubic inches; divide this amount by 231
(which is the cubical contents of a U. S. gallon in inches), and product is the capacity in
gallons.
One cubic foot of water when converted into steam expands to 1728 cubic feet at
atmospheric pressure.
The mean pressure of the atmosphere is usually estimated at 14.7 lbs. per square inch,
so that with a perfect vacuum it will sustain a column of mercury 29.9 in., or a column
of water 33.9 ft. high.
TO COMPUTE ALTITUDE BY BOILING POINT OF WATER.
517 (212°—T) + (212°—T) a = Height.
Illustration — What is the height of an elevation, when boiling point of water is
182° F.
517 X (212°—182°) -f (212°—182°) 2 = 517 X 30 + 30* = 16,410 feet.

to the amount of impurities contained in the samples experimented upon, and also due
to the slight inaccuracy of the instruments or methods used in determining high tem¬
peratures, as well as to errors in observation.

ASSAYING
SUver.—The assay for gold and silver is not a very difficult task under ordinary con¬
ditions, but there are some ores which require considerable patience and possibly greater
familiarity with chemical reactions to successfully obtain correct results.
For silver ores the method that is generally practiced is known as scorification, or the
oxidising of the metal in a clay dish, called a scorifier. The ore is weighed out (say A of
an assay ton) and placed in a scorifier and test lead (about 25 to 40 grammes, according
to the character of the ore) is placed in also. The ore and about one half of the lead are
mixed in the bottom of the scorifier, and the rest of the lead poured over the mixture so
as to form a cover. A pinch of borax glass is now thrown on the top and the scorifier
E laced in the muffle. A strong heat is maintained at first to melt the lead; this is effected
y closing the muffle door and increasing the draught. As soon as the lead is fused the
muffle door is opened. When the fusion is complete clear white fumes of lead arise from
the scorifier. The borax glass plays an important part just here by giving liquidation to
the slag so that it can be thrown to the side as fast as formed, exposing the lead for oxida¬
tion. When fusion is complete the ring of slag which is continually growing smaller closes
over the lead, the heat should be raised for a minute or so and then the sconfier is removed
from the muffle with suitable tongs, and the contents poured into a mould. When cold
the lead button is hammered into a cube shape, and during the operation the slag is loosened
from the button which is now ready for the next step, which is called cupellation, or the
separation of the silver from the lead. This operation consists in oxidizing the lead of
the lead button. The litharge formed by the neat being partly absorbed by the cupel,
and partly driven up the chimney, leaving the gold and silver together as a bead upon the
surface of the cupel. Other metals that may have remained injthejlead button from the
scorifier are also oxidized and so gotten rid of.
A cupel is a small, saucer-shaped vessel, made from pulverized calcined bones, or bone
ash. The ash is moistened with water and moulded into the required shape, after drying
thoroughly they are ready for the muffle.
When the cupel has been in the muffle a few minutes, and consequently becomes the
same temperature of the muffle, the lead button is placed in the cupel by means of suitable
tongs ana the muffle door closed. If the muffle has been of the proper temperature, in a
minute’s time or less the lead button will have quietly fused, and on opening the muffle
door will appear as a little lake of molten metal on the surface of the cupel, from which arise
fumes of oxide of lead. The closing of the muffle door at first is simply in order to melt
the lead button by increased heat and absence of air. The muffle door is now taken down
and cupellation allowed to proceed. Do not have the muffle too hot, the right degree
of heat for correct cupellation can only be acquired by experience.
As the operation continues the button gradually gets smaller and smaller, by oxidation,
and volatilization and absorption of the oxide, and this reduction continues until a point
is reached when the last of the lead leaves the bead; finally, a film passes over the Dead
and then no more action is visible. The cupel is now moved to the hottest place in the
muffle for a minute or so, and gradually brought out; do not remove the cupel too quickly,
as it is possible the bead might “spit,” that is, throw off minute particles of silver, occa¬
sioning 1088 .
When cool the bead is grasped by a pair of pincers, thoroughly cleaned and weighed,
by using the assay-ton system of weights (which is described in another part of this book) r
no calculation is necessary to find ounces per ton of gold or silver contained in the ore.
As an illustration, suppose we use ^ assay ton (A. T.) and the resulting bead weighs
U^miffigrammes, we would know at once that the ore contained 170 ounces silver per ton,
provided the ore did not contain any gold. In case the ore does contain gold, the button
is placed in a test tube or parting flask, and a small quantity of dilute C. P. nitric acid
poured in, heat gently, and if the proportion of silver to the gold is more than three to one,
the silver will dissolve, leaving a brown residue of metallic gold. The dissolved silver is
washed several times with pure water from the gold and the residue dried and heated in
a porcelain crucible, when the characteristic yellow color of the gold will be plainly seen,
this is now weighed, and the weight deducted from the original silver button, the difference
will represent the actual silver present in the pre.

ASSAYIN G— CONTINUED
Gold.—Gold assays are usually conducted by the crucible method; this process is
rather more complicated than the scorifier method. One advantage the crucible method
has, however, is that more ore can be used for assay, and on low grade gold ores this is a
necessity, as in a ^ A. T. scorifier assay, the gold might be so light as to be impossible to
weigh with accuracy.
The chemical changes in the crucible method are usually reducing, and that of scorifica-
tion (as already stated) oxidizing.
The kind and quantity of fluxes vary considerably in the crucible method, so that it
would be impossible to suggest a flux that would suit all ores. The character of the ore
determines what fluxes should be used, whether acid or basic. This selection of fluxes can
only be made by experience, for what might be termed an ordinary ore, a silicious one, with
iron, and oxidized, little lime, and little or no sulphur, the following charges might give good
results:
Ore. y* assay ton.
Bicarbonate of Soda.30 grammes.
Carbonate of Potash.15 grammes.
Litharge.25 grammes.
Argols or Flour.1 to 2 grammes.
Mix thoroughly and place in a crucible; now sprinkle considerable borax glass on the
top, and the crucible is ready for the furnace. If the ore contains much sulphur, such as
iron pyrites, or concentrates with little or no silica, the following charge might give satis¬
faction:
Ore.H assay ton.
Bicarbonate of Soda. 30 grammes.
Carbonate of Potash. 15 grammes.
Litharge.25 grammes.
Silica.15 grammes.
Borax Glass. 5 grammes.
Mix well and put in crucible three iron nails. If much lead is in the ore reduce the
amount of litharge accordingly; a covering of borax and the charge is ready for the furnace.
Have the muffle fairly hot and place crucible inside, close the muffle door and keep the heat
regular. Crucible assays should be allowed to be in the furnace from thirty to forty min-
utes; when fusion is complete the flux will be seen perfectly still. Now remove crucible and
pour contents into a mould; when cool clean the button and hammer into shape; it is then
ready for cupellation. The method from this on is exactly the same as in scorincation.
In some low grade ores, or ores containing no silver, it is a good plan to add a small
quantity of pure silver to the lead button before cupelling; this will serve to collect the gold
and have a larger button for subsequent treatment with nitric acid.
RAPID ASSAY METHODS
In the quantitative determination of elements in ores, rocks and metallurgical by¬
products, delicate but laborious schemes are used to obtain a careful and complete analysis.
When, however, the principal constituents are required, with results reasonably accurate
for practical metallurgical purposes, the tedious gravimetric processes have been replaced
in smelting works by quicker volumetric schemes, which enable the chemist to turn out a
large number of determinations in a day; moreover, by continued daily use of these methods
the chemist has been enabled to approach, and even to equal in accuracy, the more elaborate
schemes before mentioned. The following processes have given satisfaction:
Silica. (SiOj.)—Charge 0.5 gramme. Run to dryness with 5 cc's hydrochloric acid
and 3 cc’s nitric acid (replace hydrochloric acid by nitric acid according to the amount of
sulphides present), take up with hydrochloric acid, add hot water, boil and filter, wash with
hot water, and once with ammonia acetate, dry first in annealing cup or porcelain crucible
before muffle, ignite, and weigh as silica.

ASSAYIN G —CONTINUED
Barium Sulphate. (BaS(> 4 .)—When the chemist has reason to suppose that the ores
contain barium sulphate, the silica, after weighing as above, is fused in a platinum crucible
with about 5 grammes of a mixture of equal parts of sodium and potassium carbonates,
dissolved in hot water, filtered, and washed; then dissolve the barium carbonate through
the filter in dilute hydrochloric acid, add water, then sulphuric acid, boil hard, filter, ignite,
and weigh as barium sulphate, which subtracted from the original weight gives silica.
Iron. (Fe.)—The filtrate from the silica is boiled, reduced while hot by the addition of
a few drops of strong stannous chloride (made by dissolving metallic tin in hydrochloric
acid), allowed to cool, mercuric chloride added in large excess, and titrated with a standard¬
ized solution of bichromate of potassium, (4.39 grins, to the litre of water), using a very
weak solution of ferri-cyanide of potassium as indicator. (1 cc. bichromate solution equals
0.005 grms. iron.) Instead of reducing the iron as above, if it is desired to determine lime,
the iron is precipitated by ammonia water, boiled, filtered off, dissolved through filter by
dilute hydrochloric acid, reduce and continue as before, and the filtrate from the iron is
treated for lime by immediately adding oxalate solution as below.
Lime. (CaO.)—Charge 0.5 grm. Dissolve in 5 cc’s hydrochloric acid and 3 cc’s
nitric acid, neutralize with ammonia water without adding great excess, re-dissolve the iron
by adding a very hot solution of oxalic acid, boil hard, settle, decant twice on filter and wash
until washings fail to discolor a drop of permanganate of potassium in dilute sulphuric acid.
Wash precipitate through filter into a beaker containing hot sulphuric acid, boil, titrate hot
with a solution of permanganate of potassium (5.7 grms. to the litre of water). Iron
standard of permanganate of potassium multiplied by 0.5 gives the standard for lime, or in
other words 1 cc. permanganate equals 0.005 grms. lime.
Magnesia. (MgO.)—The filtrate from the lime is treated with large excess of ammonia
and a solution of sodium phosphate added, about 5 grammes dissolved in water; the mixture
is allowed to stand twelve hours in a cool place, filtered, washed with dilute ammonia and
cold water, ignite in assay muffle and weigh as magnesium pyrophosphate, from which
magnesia is obtained by multiplying the result by 0.36036.
Zinc. (Zn.)—Charge one gramme in covered casserole, add 20 grms. ammonia nitrate
salt and 5 cc’s nitric acid, run to dryness, cool, and add 20 cc’s hot water and 15 cc’s am¬
monia, boil four minutes, filter, and if filtrate has a brownish tinge (due to manganese) add
10 cc’s more ammonia, boil with cover off and refilter, make acid with hydrochloric acid and
add 7 cc’s excess, also 30 grms. granulated lead, or less according to the amount of copper
present as indicated by blue color; let stand until the solution clears, or place filtrate and
lead in a small flask, and shake to precipitate the copper. Let cool, titrate with solution of
ferro-cyanide of potassium (45 grms. to the litre of water), using acetate or nitrate of ura¬
nium as indicator. 1 cc. of solution used equals 0.01 grm. of zinc.
Manganese. (Mn.)—Charge 0.5 gramme. Dissolve in 5 cc’s hydrochloric acid, add
5 pc’s nitric acid, neutralize with emulsion of zinc oxide, filter into a large flask, dilute with
water to about 400 cc’s, boil hard and titrate quickly with permanganate ot potassium,
shaking the flask vigorously after each addition. The iron standard multiplied by 0.294
gives the standard for manganese.
Alumina. (A1 2 0 8 .)—In fire clays, etc., not soluble in acids. Fuse 0.5 grm. in a plati¬
num crucible with 5 to 7 grms. of mixed alkaline carbonates, dissolve in hydrochloric acid,
run to dryness, take up with hydrochloric and nitric acids and filter off the silica (this scheme
applies to any substance insoluble in acids in which silica is desired. The chemist should be
careful in testing lead ores to dissolve out the lead with nitric acid before fusing in a platinum
dish). The filtrate is neutralized and boiled with caustic potash. The iron is filtered off
and determined if desired. Add hydrochloric acid very slight excess to the filtrate, and add
ammonia, boil, filter ignite precipitate, and weigh as A1 2 0 8 .

Lead.—Weigh % to 1 grin, in covered casserole, add 10 cc. nitric acid, warm until red
fumes are off, add 10 cc. sulphuric acid and boil to white fumes, cool, add 30 cc. water, boil
and filter into 500 cc. flask, washing with cold water.
Wash residue back into casserole, add 5 grm. C. P. ammonium chloride and 1 cc. C. P.
HC1, boil until dissolved, add 5-10 cc. ammonium sulphide, boil and filter through the
original filter. Rinse lead sulphide back into casserole, add 7 cc. (1-10) sulphuric acid,
shake to break up clots, add 25 cc. strong hydrogen sulphide water and filter.
Put filter with contents into casserole, add 5-10 cc. HC1, boil out hydrogen sulphide
add few drops nitric acid, then 25 cc. cold water, then slight excess ammonia, and then
make distinctly acid with acetic acid. Boil, dilute to 200 cc. with hot water and titrate
with ammonium molybdate solution using, tannic acid (.1 grm. in 20 cc. water) as indicator
until a yellow tinge shows on spot plate.
The ammonium molybdate is made by dissolving 8.5 grms. in one litre water; 1 cc.
equivalent to about .01 grm. lead.
To standardize, weigh .4 grm. C. P. lead foil, add 3 cc. nitric acid and 6 cc. water and,
after solution, boil just to dryness. Dissolve in 30 cc. water, add 5 cc. sulphuric acid,
agitate, settle a short time and filter. Put ppt. and paper into beaker and boil with 10 c.c.
HC1 until paper disintegrated, add 15 cc. HC1, 25 cc. cold water and then 25 cc. or so am¬
monia to alkalinity. Distinctly acidify with acetic acid, dilute to 200 cc. with hot water,
boil and titrate.
Copper. (Cu.)—To the filtrate in 500 cc. flask from lead precipitate (see previous
paragraph), is added 5 grammes of powdered or granulated metallic zinc, or sheet aluminum,
and the whole allowed to stand until the copper is precipitated from the solution, as in¬
dicated by testing a couple of drops of the clear liquid with sulphuretted hydrogen. Ten
cc’s sulphuric acid are added to dissolve the excess of zinc used, the flask is then thrice filled
with hot water and decanted. (These combined decantations can be immediately titrated
for iron with permanganate of potassium.) The moss copper is dissolved in 3 cc’s nitric
acid, red fumes boiled off, 10 cc’s ammonia water added and titrated with a solution of
potassium cyanide, 25 grms. to the litre of water, (1 cc. equals about 0.005 grammes copper),
until the color is nearly bleached, dilute 100 cc’s and titration completed. Dissolve about
0.200 grm. of pure copper in about 3 cc’s nitric acid, and add 10 cc’s of ammonia water, titrate
with the cyanide solution, and note the number of cc’s required to decolorize. Make cal¬
culations accordingly. As cyanide of potash solutions do not remain of constant strength
the solution should occasionally be standardized by pure copper as before stated. Some
metals interfere in a measure with this method, but is exact enough for practical purposes.
Sub-Iodide Method for Copper.—Digest. 5 to 1 grammes of ore with 5 cc’s nitric acid,
5 cc’s hydrochloric acid, 10 cc’s sulphuric acid, boil until white fumes, add 40 cc’s water, boil,
and filter through a 9 cm. filter to get rid of lead sulphate, bismuth sulphate, etc., wash with
water acidulated with sulphuric acid, do not get over 75 cc’s of solution in a No. 2 beaker.
Put in solution a piece of aluminum foil or sheet and boil, when effervescence commences
boil for about five minutes afterward, decant on a 9 cm. filter and wash, add a little nitric
acid to the filter to dissolve any copper that may have been retained, and add to the copper
in the beaker, dissolve with nitric acid, care being taken not to have too much solution,
transfer into an 8 oz. pear-shaped flask, add Yi grm. potassium chlorate, and boil down to
about 2 cc’s or until it gets thick; care must be taken not to boil to dryness, take up with 5
cc’s water, then add 5 cc’s ammonia, boil about a minute, add 6 cc’s acetic acid, and 40
cc’s water and titrate. Standard solution of hyposulphite of soda: 19 grammes of hy¬
posulphite to 1 litre. One cc. equals about 0.005 grm. copper.
Put in a flask 3 grammes potash iodide, and add at once hyposulphite of soda solution
until solution turns yellowish, then add starch solution and titrate, tne end reaction being
very distinct. Weigh out pure copper and treat same as above and estimate strength of
hyposulphite of soda solution (as in the case of cyanide of potash method.)

Copper (by Battery.)—Weigh out from H to 1 gramme of ore in a No. 2 beaker, just
moisten with a drop or two of water, then add from 10 to 15 cc’s of strong nitric acid, and
5 to 8 cc’s. of sulphuric acid; heat until white fumes of sulphuric acid are given off. Be sure
that all of the ore (which is soluble in acids) has been dissolved, then dilute to about 30 cc’s,
heat again, just to boiling, to disintegrate the mass, filter off residue in which the lead and
silica may be determined if desired. Filter solution into a No. 2 beaker, add one or two
strips of heavy aluminum foil, and boil for 10 or 15 minutes, which is generally sufficient to
insure complete precipitation of the copper. Pour off the solution and wash three times
by decantation with hot water. Then add 3 or 4 cc’s of strong nitric acid to the contents of
the beaker, allowing the acid to flow over the aluminum. Boil to expel the nitrous fumes,
decant into another beaker (which should be narrow) and rinse the aluminum with a few
cc’s of water, just neutralize the solution with ammonia, and add about 15 cc’s of 1 to 10
sulphuric acid. Place platinum cylinder into the solution connecting it with the negative or
zinc element of the battery; inside of the cylinder place a platinum wire spiral reaching
almost to the bottom of the beaker, being careful not to allow the spiral to touch the cylin¬
der.
A very good battery for this purpose is a Bunsen cell; about eight hours is usually re¬
quired for a total precipitation of copper. To determine if all the copper has been precip¬
itated, dilute solution in beaker so as to raise it over the precipitated copper on the cylinder }
and if all the copper has been precipitated there will be no further deposition of copper on
the cylinder after an hour. Another test is by removing a drop or two of the solution and
testing it with hydrogen sulphide. If test shows that all copper has been removed, then
without turning off the current, remove the cyfinder and place immediately into a beaker of
warm water so as to wash off as quickly as possible all acid from the cylinder. It is always
advisable to have two beakers of water so as to give the cylinder two washings, thus insuring
a quick and absolute removal of all acids and salts. After cylinder has been thoroughly
washed, place into a beaker of alcohol which removes the water; then dry as quickly and
carefully as possible, avoiding the oxidation of the copper on the cylinder. The precipitated
copper should be a bright rose-red color.
In case the ore contains only a trace of arsenic, antimony or bismuth, the precipitation
of the copper on the aluminum, oil may be dispensed with. In that case after the ore has
been dissolved; and the mass disintegrated, add enough ammonia to just neutralize this
solution; and add H gramme ammonia nitrate and 15 cc’s of 1 to 10 sulphuric acid, place
on battery same as before.
j&Tin. (In alloys.)—The alloy is oxidized with moderately strong nitric acid, the mass
mixed with an excess of ammonia and sulphide of ammonia, and digested for some time in a
closed flask. In this way the tin is entirely dissolved as a sulphide. The solution is filte red
off from the other sulphides, which are then washed with very weak sulphide of ammo.nia,
and dried. From the solution the bisulphide of tin is precipitated by dilute hydrochloric
acid, filtered off, washed and dried. It is then gradually heated together with the filter, in a
porcelain crucible, with free access of air, at first gently, then ultimately to redness, then
cool and moisten with nitric acid and heat to redness, so that it may be entirely converted
into binoxide of tin, and weigh as such. A fragment of ammonium carbonate is held in the
crucible at the end of the operation to remove any sulphuric acid that may have been
formed.
Tin. (In ores.)—Dissolve ore in aqua regia, filter off solution containing lead and cop¬
per. Dry residue and place in a porcelain crucible and ignite; after all carbon has been
burned off, add 3 parts of sodium carbonate and 3 parts of sulphur, then fuse, dissolve this
mass in water and filter off silica, acidify filtrate with hydrochloric acid, and pass in hy¬
drogen sulphide; this precipitates the tin sulphide. Filter this sulphide and treat same
as above, (in alloys).

ASSAYING— CONTINUED
BLAST-FURNACE SLAGS
To obtain a sample slag which shall be soluble in acids, an iron rod is dipped into a pot
of molten slag and the adhering slag quickly cooled in a jet of water. A small portion, 3
grammes, is pulverized exceedingly fine in an agate mortar and the elements determined as
follows:
Silica and Lime.—Half gramme charge in porcelain evaporating dish and 2 cc’s hot
water, stir, add 3 cc’s hydrochloric acid and run to complete dryness, stirring meanwhile to
prevent spitting, cool, take up with 3 cc’s hydrochloric acid, stir, and add hot water, boil
and filter, weigh up residue as silica, and determine lime in filterate as described in method
for lime assay after adding about 4 cc’s nitric acid to oxidize the iron.
Iron.—Dissolve half a gramme charge in a beaker by adding 25 cc’s hot water, stirring,
and then adding 10 cc’s hydrochloric acid, boil ; reduce with stannous chloride, add excess
mercuric chloride, and titrate with potassium bi-chromate, as in the method of iron assay.
Manganese.—Treat half a gramme charge in a porcelain evaporating dish using in¬
verted funnel for cover, with 5 cc’s nitric acid, 2 cc’s sulphuric acid, and 1 cc. hydrochloric
acid, heat just to pasty condition, take up with water ana 2 cc’s nitric acid, neutralize with
zinc oxide, and proceed as in the method for manganese assay.
Slags have been repeatedly analyzed for silica, iron, lime and manganese by the above
methods, in forty minutes.
ARSENIC AND ANTIMONY
(L. B. Skinner and R. H. Hawley)
Solutions.—Copper, Zinc Chloride. To one pound C.P. stick zinc add 500 cc. water
and then gradually add 1200 cc. C.P. hydrochloric acid. Boil this solution until the boiling
point reaches 108* C.
Dissolve 300 grams C.P. cupric chloride in one litre C.P. hydrochloric acid and mix this
solution with the zinc chloride made as above.
Standard Iodine. Dissolve 75 grams potassium iodide in the smallest amount of water
possible and to this add 34 grams of iodine. After the iodine is all dissolved make up to two
litres, which should give a solution such that one cc. is equivalent to .005 grams arsenic.
Weaker standard solutions may be used for more delicacy.
To Standardize. Take 300 milligrams C.P. arsenious acid (AsjOs), dissolve in about 2
grams caustic soda in water, dilute to 200 cc., acidify faintly with hydrochloric acid, cool
thoroughly, add 2 grams sodium bicarbo'nate and then some starch solution, titrating to a
permanent blue color.
300 milligrams arsenious acid multiplied by .7576 gives .2273 grams arsenic. This
weight divided by the number of cc. used gives the value per cc.
Run a blank on the zinc copper chloride solution by dissolving 300 mgrm. arsenious acid
in caustic soda acidifying with HC1, precipitating with hydrogen sulphide and distilling as
outlined in the scheme following. This on the same amount of arsenic may show a higher
burette reading owing to impurity in the copper chloride used. Deduct the number of cc.
over the standard from all regular determinations.
Ores.—For heavy sulphide ores low in arsenic weigh in 25 grm. of finely ground pulp,
digest with 100 cc. C.P. nitric acid in a 6-inch porcelain dish (the acid being added slowly),
boil out red fumes, add 75 cc. C.P. sulphuric acid and boil to copious white fumes. Cool
the dish, add about 150 cc. water, 50 cc.HCl (10 grm. tartaric acid, if Sb is to be determined),
and carefully boiljto dissolve’all salts.
Filter into a No. 6 beaker, nearly neutralize the filtrate with ammonia, heat to about
70° C. and add slowly, with stirring, a mixture of 15 cc. ammonia bisulphite and 30 cc. am¬
monia until almost all the red color has disappeared, showing a thorough reduction. Add
a little HC1 to decompose all the sulphite and boil until there is no odor of sulphurous acid.

ASSAYIN G— CONCLUDED
While hot, pass sulphuretted hydrogen in a lively manner for about 30 minutes or until
precipitation is complete; filter through 11 cm. paper and test filtrate with hydrogen sul¬
phide. The washed ppt., with paper, is put into distilling flask and 50 cc. of the copper zinc
chloride solution is poured in through a funnel reaching below the side opening. If the ppt.
is too bulky to get in with ease, it may be dried some.
The distilling apparatus is a 6 or 8 oz. flask with the side arm bent down to fit into a
Liebig condenser set vertically. Heat is supplied by a small flame such as that from an
alcohol burner. The lower end of the condenser just dips into about 40 cc. of water in a
No. 1 beaker. A thermometer is inserted through a rubber stopper fitting the neck of the
flask so that the bottom end is K-inch from the bottom of the flask.
After charging the distilling flask, heat is applied and the distillation proceeded with
until the thermometer registers 115° C. This should take about 15 minutes and the arsenic
should be all over; to make sure, the stopper may be removed, 10 cc. HC1 added and a
second distillation made. Some elementary sulphur distills over, but this does no harm.
Pour distillate into No. 3 beaker, add excess ammonia, just acidify with HC1, cool
thoroughly, add sodium bicarbonate and starch solution and titrate with standard iodine
solution to first permanent blue color, deduct the excess found in the blank and calculate the
arsenic.
Antimony. —Add about 50 cc. saturated zinc chloride solution to the residue in the
flask, replace the thermometer by a glass tube reaching nearly to the level of the liquid and
through this tube pass hydrochloric acid gas generated by sulphuric acid, dropping from a
separatory funnel into liquid HC1 at the rate of about two drops a second.
The condenser is sealed as before with cold water and heat is applied to the flask until
the mass is about dry, removing the beaker from the condenser every few minutes to see if
the antimony has ceased coming over. To these beakers is added a little tartaric acid to
keep the antimony in solution, ammonia is added to nearly neutralization and hydrogen
sulphide passed through to precipitate the orange red sulphide. When the beaker last re¬
moved shows only a small amount of precipitate, stop heating the flask, combine the distil¬
lates, thoroughly ppt. with H 2 S, filter on a tared gooch crucible, heat about one hour at 255°
C. to constant weight and multiply by .714.
Do not heat too strongly or copper will come over which may be told by the darkening
of the orange red ppt.
This scheme may be most satisfactorily used for 1 grm. charges on high arsenic ores by
using the usual amounts of acid for casserole work, not filtering off gangue where the amount
is low and not neutralizing the filtrate before the reduction with bisulphite.
Sulphur. (S.)—Charge one gramme in iron dish with about 10 grammes of a mixture
of 5 parts of carbonate of soda and 3 of nitrate of potassium, heat slowly in a muffle until the
mass swells up; cool, dissolve in hot water, filter, make acid with hydrochloric acid, add so¬
lution of barium chloride, boil hard, settle, decant, filter, ignite, and weigh as barium sul¬
phate, multiply the result by 0.1374 to obtain sulphur. Or the ore may be treated with
nitric acid, boil nearly to a dryness, take up with hydrochloric acid, boil until the nitric acid
is entirely evaporated, dilute with water, filter, add water to about 300 cc’s, warm, and add
excess barium chloride, filter, wash precipitate well, ignite, and weigh as above.

CYANIDE
HOW TO DETERMINE PURITY OF POTASSIUM CYANIDE
Take a sample of the KCN to be tested across the thickness of the cake. Reduce
this sample by crushing to a fine powder. To one gram of this reduced sample add 100
c.c. of distilled water. Take 10 c.c. of this solution and titrate it with standard Silver
Nitrate. The number of c.c. of Silver Nitrate reauired to produce a permanent precipitate
multiplied by five will give the percentage of KCN contained in sample.
The above is not a determination of actual Cyanogen present, but a simple test to
give working value of Cyanide.
STRENGTH OF KCN SOLUTION
To 1000 c.c. of distilled water add 6.535 grains of c.p. Silver Nitrate andsta ndard-
ize with a known strength of Cyanide solution.
For determining the amount of Cyanide in solution, take 10 c.c. of the solution
(measured in a pipette) and place it in a small beaker: titrate this with the Silver Nitrate
solution, until an opalescent precipitate appears. The number of c.c. of Silver Nitrate
used in tritration will then equal the number of pounds of Cyanide in one ton of the solution.
TESTING CYANIDE
The standard test in use is the so-called Nitrate of Silver test. This test is based on
the fact that Cyanides form with Nitrate of Silver, when both are in solution, precipi¬
tates. In practice, a given quantity of Cyanide to be tested is dissolved in distilled water
and titrated with one-tenth normal solution of Nitrate of Silver. As the curdy white
precipitate, Cyanide of Silver, readily dissolves, as long as there is a surplus of Cyanide
m the solution present, sufficient Nitrate of Silver solution is added until a permanent
milky appearance is obtained. The addition of a small quantity of Chloride of Sodium or
Iodiae of Potassium will help to give a more distinct reaction to the eye. Each cubic
centimeter normal solution of Nitrate of Silver is equal to 0.013 grams pure Cyanide,
so the exact strength of the Cyanide is easily ascertained. It is obvious that the strength
of the Nitrate off Silver solution may be so adjusted as to save all further calculation.
This formula is also useful for estimating the strength of Cyanide solution.
ACIDITY TEST
Place fifty grams of pulp in a bottle suitable for agitating; add 25 c.c. of a deci-normal
(N/10) caustic soda solution (as described further on) and 75 c.c. of water; agitate for
an hour and filter off the solution. Titrate 20 c.c. of this filtrate with a deci-normal (N/10)
solution of Sulphuric Acid, using as an indicator Phenolphthalien or Methyl-Orange.
Five minus the Burette reading, multiplied by 2, will give the number of pounds of
lime necessary to add to each ton of ore to keep the Cyanide solution at the proper point
of alkalinity.
In connection with the above, lime is presumed to be 65° pure.
It is advisable before making above acid test to agitate fifty grains of ore with 100
c.c. of water, filter and try the filtrate with litmus paper. If this shows a strong reaction,
there is a quantity of free acid present, which may De removed by a water wash.
PREPARATION OF N/10 SULPHURIC ACID SOLUTION
Add 30 c.c. concentrated c.p. Sulphuric Acid to a litre of distilled water: make de¬
termination of Sulphuric Acid and correct until solution is absolutely normal j each c.c.
of this solution then contains .049 grains of H2SO4J add 100 c.c. of this solution to 900
c.c. of distilled water, and we have the N/10 solution, each c.c. of which contains .0049
Sulphuric Acid.

CYANIDE— CONTINUED
PREPARATION OF N/10 SODIUM HYDRATE SOLUTION
Dissolve about 66 grains of pure Caustic Soda in 1000 cc. of distilled water (this
will give a solution slightly stronger than normal). Titrate this with the normal Sul¬
phuric Acid solution, using Litmus or Phenophthaiien for an indicator; make corrections
and titrate again until one cc. of this solution is equivalent to one cc. of Sulphuric Acid.
Add to 100 cc. of this solution 900 cc. of distilled water and one cc. of this N/10 solution
will neutralize one cc. of N/10 Sulphuric Acid solution.
DETERMINATION OF SULPHUR IN H*S0 4
Place in weighed platinum dish two grains, approximately, of recently heated Sodium
Carbonate. Dissolve with a small amount of distilled water, cover and carefully add 25
cc. of Sulphuric Acid to be tested.
Evaporate to dryness on water bath. Remove cover and dry at 180° in air bath to
constant weight.
In this process S0 4 =96 has displaced CO*—60; the difference in weight of platinum
dish and contents before and after adding Sulphuric Acid is proportionate to amount
of HsS 0 4 in the 25 cc. Then (96—60) : 98 :: difference in weight : x (HaS0 4 in 25 cc.).
x^25 = .049.
DETERMINATION OF OTHER CONTENTS OF ORE WHICH WILL DECOMPOSE
KCN
Place 500 grams of the ore in a percolator and add 1000 cc. of 10 pounds solution,
allowing it to stand for 12 or 16 hours, and then drain slowly. Titrate the drained solution
to determine Cyanide contents and note loss in strength.
Make another test with a sample to which lime has been added, as determined by
acid test. Note the difference between the two tests, which will represent the loss due
to the presence of other decomposing contents of the ore than the acid.
If this loss is heavy, a determination must be made to ascertain the cause.
TO DETERMINE ALKALINITY OF CYANIDE SOLUTION
Take 10 cc. of solution in a small beaker, and titrate it with Silver Nitrate for
Cyanide. Add as much more Silver Nitrate as used in the titration, then add an excess
of Potassium Ferro-Cyanide; add a drop or two of Phenophthaiien and titrate with N/10
Sulphuric Acid solution.
If the solution contains much zinc, it will be necessary to filter before titrating.
The Burett reading multiplied by .0112 will give the percentage of protective
alkalinite of the Cyanide solution, which should be about 2%.

Alfred Chiddy’s Method
Add to four assay tons (or more) of the solution 10 cc. of 10% solution of lead acetate;
then 4 grains zinc shavings; boil a minute; and 20 cc. HC1 (strong). When action has
ceased, boil again and decant from the ball of spongy lead, which has been decanted a
little with a glass rod, and wash same by decantation. Transfer to a piece of filter paper,
roll into a compact ball and place (without drying) on a hot cupel in the muffle.
It is best to transfer the compact ball from the filter paper to a piece of c. p. lead foil
and then cupel directly or scorify first, then cupel.
Do not add all of the 20 cc. HC1 at once, as zinc may break up on account of violent
action.
Another Method
Take a piece of c. p. lead foil and form a tray about 5 inches long, 2 inches wide and
% inches deep, and evaporate in this tray from one to three assay tons of the solution
until dry, and then cupel the lead.
It is seldom necessary to scorify the lead before cupelling, unless the solution is very
foul.

STANDARD SOLUTIONS
An Empirical solution is a standard solution, 1 cc. of which contains sufficient of the
active reagent to neutralize 1% of the substance to be estimated, when M or 1 gramme of
sample is weighed out.
A Normal solution is a standard solution containing in one litre the Hydrogen Equiv¬
alent in grammes of the active reagent.
By Hydrogen equivalent in the case of acids and alkalies is meant the acidity or
basicity of the substance, as:
Hydrogen Equivalent of H Cl, 36.4-5-1-36.4
Hydrogen Equivalent of H*S0 4 , 98.0-5-2=49.0
Hydrogen Equivalent of NaOH, 40.0-5-1 =40.0
In case of a precipitation the Hydrogen Equivalent would be the yalence of the atom
precipitated.
In case of the oxidation or reduction, ascertain the atoms of oxygen absorbed or given
off by molecule of the active reagent.
Indicators used are Litmus, Methyl Orange, Cochineal and Phenolphthalein. Methyl
Orange cannot be used in the presence of vegetable salts and acids. Cochineal cannot be
used m the presence of iron salts. Phenolphthalein cannot be used in the presence of NH*

mine the exact amount of H 2 S0 4 in this solution by precipitation with Ba Cl 2 . From this
result figure the exact amount of H 2 S0 4 in 1 cc. of solution. The reason 50 grammes
are weighed out instead of 49 grammes, the calculated amount, is that C. P. sulphuric
acid contains about 97.5% H 2 S0 4 (the balance being water).
The amount of H 2 S0 4 in one cc. of a normal solution is 0.049 grammes. Suppose it
is found that one cc. of acid solution contains 0.0539 grammes of sulphuric add instead of
0.049, showing it to be too strong, therefore to make it just normal it must be diluted.
0.049:0.539: :1000 cc.
( cc’s taken out to )
l determine H 2 S0 4 )
S No. cc’s solution )
should contain. )
Therefore dilute solution to the number cc’s it is found that it should contain.
STANDARD NORMAL SODIUM HYDRATE SOLUTION
Hydrogen Equivalent of NaOH, =40-5-1 =40.
Weigh out 42 grammes NaOH, dilute to 1 litre. Take an exact number of cc’s of
this solution, place in a flask, dilute to 150 cc. and add a few drops of Methyl Orange as
indicator. Titrate this with standard sulphuric add. This will give the exact wdght
of NaOH in sample taken.
49:40::Wt. of sulphuric add neutralized: Wt. of sodium hydrate neutralized. Divide
this result by the number of cc’s taken gives weight of NaOH in each cc. of standard
solution.
Figure the volume of exact normal solution as above in sulphuric acid. Accurate
adjustment to make the solution just normal in this manner is difficult and in most cases
it is better to determine factor by which readings must be multiplied in order to correct
the difference between the real strength of solution and normal strength.

STANDARD SOLUTIONS
STANDARD DECINORMAL KMn0 4 SOLUTION.
To make a solution of KMn0 4 such that 1 cc. shall equal 0.0056 grammes of iron.
2 KMnO 4 +10 FeS0 4 +8 H&Oi-KSOt+S Fe, (SOOt+2 Mn S0 4 +8 H,0.
2 KMn0 4 -K|0+Mn 2 07
Mnt0 4 -2 MnO+5-O.
One atom of oxygen will oxidize 2 atoms of iron, therefore KMn0 4 will oxidize 5 atoms
of iron.
Molec. Wt. of KMn0 4 -158+5 -31.6.
A decinormal solution will be 31.6 grammes-*-10=3.16 grammes.
Therefore weigh out 3.16 grammes KMn0 4 .
Make an empirical solution of KMn0 4 such that 1 cc. of solution will equal 1% of
iron when one gramme is weighed out.
From the above equations:
31.6 grammes KMn0 4 in one litre of solution 1 cc. of which =-0.056 grammes iron.
To make 1% solution 1 cc. will have to equal 0.01 gramme Fe.
Therefore 31.6 : 0.056 :: x : 0.01.
31.6x0.01
-—5.64 grammes KMn0 4 .
0.056
5.64 grammes KMn0 4 are required to make 1 litre of solution equal to 1% of iron for
1 gramme sample weighed out. Standardize the above solution with a known iron solu¬
tion. Dissolve .25 grammes of clean piano wire, which contains 09.7% iron, in dilute
hot sulphuric acid in a flask, being careful to exclude air from the flask as much aslpossible.
Expel air from flask by adding a small quantity of sodium carbonate. WhenTail iron is
dissolved and hydrogen boiled off, dilute to about 150 cc.’s and titrate with KMn0 4 solu¬
tion.
STANDARD DECINORMAL K 2 Cr 2 0r SOLUTION.
Make a solution of KiCriQr such that 1 cc. =0.0056 grammes Fe.
K*Cr 2 07+6 FeCli+14 HC1-2 KCl+Cr 2 Cli+7 H a O+3 Fe s Cl#.
K 2 Cr 2 07 —K 2 0-f -2 CrO*-*-2CrOi —Cr 2 0*-f-3-0.
Three atoms of oxygen will oxidize 6 atoms of iron.
Molec. Wt. of K 2 Cri07 -296.56+6 - 49.4 grammes.
Weigh out one-tenth of 49.4 grammes—4.94 grammes for decinormal solution equal
0.0056 grammes iron.
« Make empirical solution, such that lcc. will equal 1% of iron when 1 gramme of
sample is taken.
Therefore as above for permanganate solution, we have:
49.4 : 0.056 :: x : 0.01
_ 49.4x0.01
-- —8.82 grammes :K 2 Cr 2 07 required to make 1 litre of solution of above
0.056 strength.
To standardize these solutions dissolve .25 grammes of clean piano wire in hydrochloric
acid. Treat this the same as in method for the determination of iron by KiCriOy solution
given under the head “Rapid Assay Methods. 1 ’
As 4 before stated it is difficult to obtain an accurate normal or empirical solution,
therefore it is best in most cases to determine factor. This is figured the same as under
Standard Sodic Hydrate solution. The Permanganate solution cannot be used in the pres¬
ence of hydrochloric acid, arsenic or antimony,
j JThe Bichromate solution is equally effective in both sulphuric and hydrochloric acids.

QUALITATIVE TESTS FOR IMPURITIES IN
AQUA AMMONIA
Sulphates.—Dilute the aqua ammonia with distilled water, acidify the solution with
strictly chemically pure hydrochloric acid and add a few drops of a solution of barium
chloride. If a white precipitate forms, sulphates are present.
Chlorides.—Dilute the ammonia with distilled water, acidify with chemically pure
nitric acid and add a few drops of silver nitrate solution. A white precipitate, which
redissolves upon the addition of more ammonia, indicates the presence of chlorides.
Carbonates.—Dilute with distilled water, add clear lime water and allow to stand
a few minutes. A white precipitate indicates the presence of carbonates.
Organic Matter.—Dilute 10 cc. of aqua ammonia with 10 cc. of distilled water, add
20 cc. of C. P. nitric acid (Sp. Gr. 1.42) very slowly so as to avoid raising the temperature
appreciably. A distinct organic odor and a very slight reddish color should develop if
organic matter be present.
SOLUBILITY OF METALS IN AQUA AMMONIA,
in the order of their solubility:
Copper — quite soluble.
Zinc,
Nickel,
Cobalt,
Lead,
Iron — Very slightly soluble, if at all.
Aluminium — Very slightly soluble, if at all.
Magnesium — Very slightly soluble, if at all.
IMPURITIES IN C. P. ACIDS
and Tests foe Same.
Hydrochloric Acid.
For Iron. — Dilute, and add KSCN; if it shows a red color there is iron present.
For Arsenic. — Dilute, pass in hydrogen sulphide gas; if a distinct yellow precipitate
is obtained it would indicate traces of arsenic; also try by the Marsh test.
For Sulphuric Acid. — Dilute, add barium chloride; a white precipitate would be
obtained if sulphuric acid were present.
Nitric Acid.
For Chlorine. — Add silver nitrate, if slight opalescence occurs/it shows presence
of chlorine.
Sulphuric Add.
For Arsenic. — Dilute and pass in hydrogen sulphide gas; if a distinct yellow precip¬
itate is the result it shows the presence of arsenic; also try by the Marsh test.
For Iron. — Dilute, add KSCN; if red color appears it shows presence of iron.
In making these tests extreme care should be taken that all of the glassware and
apparatus used in the tests are absolutely free from the impurity tested for; also make
tests on the distilled water to be used in the examination, so as to be sure the water is
perfectly pure.
Always pour acid into water, and not water into acid, to avoid explosions.
Never grind potassium chlorate and sulphur together. It is very explosive.
Formula for Blue Prints:—
Potassium ferricyanide.150 grms.
Ammonia, citrate of iron.150 grms.
Water.600 cc.
Dissolve each of the salts in half the water, mix and coat one side of the paper, dry
in dark room. Expose to light and develop by floating in water.
