THOMAS COMPANY HIS copyright protects all the copy- rightable component paris of the cata- logue, including the text and illustrations. Electrotypes of the woodcuts used in this catalogue are loaned, on request, to authors for tllustration of their text. Electrotypes of our wholesale specialties are furnished dealers for use (without mutilation) in the preparation of their catalogues. Electrotypes of all other items are made for our own use and are not loaned to dealers, nor is their reproduc- tion in any way without our authority permitted by us. PRINTED BY THE FRANKLIN PRINTING COMPANY, PHILADELPHIA-NEW YORK PREFACE PRICES—The prices in this catalogue are subject to change without notice and, with the exception of original package discounts indicated, are mostly net. In unity with the practice of some manufacturers, we also allow a special institutional discount to colleges and hospitals on Microscopes and accessories. Our prices are subject to daily control and on all trade-marked or branded items they are identical with those established by the manu- facturer. On all other items they are in accord with market conditions, being computed upon our net costs by means of definitely established formulae. Our prices are always identical on open orders and competitive pro- posals. Where time permits and exact advance information as to expenditure is required, we submit upon request an itemized Statement of Current Prices for the items selected. TERMS, DOMESTIC—Prices are f. 0. b. Philadelphia, boxing included except where otherwise specified in the catalogue and our terms of payment on open accounts are net cash thirty days from date of bill. Individual and commercial customers having no account with us, and regarding whom credit information is not readily ob- tainable through the usual channels, are requested to remit with order or send satisfactory credit references. TERMS, EXPORT—Prices are f. 0. b. Philadelphia, with special export packing charged extra at cost. Delivery is free alongside in overseas shipment where steamer sails from the port of Philadelphia. Payment for export shipments is preferred by means of a banker’s confirmed letter of credit in par New York funds, drawn in our favor on a Philadelphia or New York bank, available upon presentation of invoice and shipping documents. Where small amounts are involved, advance payment is suggested in par New York funds. To foreign firms and institutions whose credit and other responsibility are known to us or readily ascertainable in the U. S., we ship with draft at sight with documents attached for delivery against payment with interest and banker’s collection charges included. All terms of payment for export shipment are subject to change without notice because of war or political conditions. STOCK—All current items listed in this catalogue are carried in our own stock for immediate delivery with the exception of a very few items, of which prompt factory shipment is usually possible. The maintenance of so large and varied a stock is to be understood as subject to certain interruptions beyond our control in the way of manufacturer’s and transportation delays, strikes, war, etc. RETURN OF GOODS—Customers are requested not to return goods for any reason until after communi- cation is had with us. When the return is arranged, suitable tags are sent which, when attached_to the articles in question, insure prompt credit, repair or exchange, as indicated. The time involved in such preliminary ar- rangement is insignificant compared with the time and labor required to establish the identity and disposal of goods sent us without such precaution. BREAKAGE AND SHORTAGE—Although our shipments are checked and packed by experienced em- ployees under rigid control, breakages and shortages occasionally occur because of defective packing or of our mistakes. When such claims are clearly and promptly presented to us it is our custom to adjust them without undue argument, as we subordinate literal terms of contract to an underlying spirit of fairness and retain our interest in each transaction until our customer receives full satisfaction and value, no matter where or when our technical responsibility may end. We further assist in presenting established claims against the transportation companies from which we hold receipts for shipments. Customers will greatly facilitate the adjustment of such claims by refusing to receipt for goods received in damaged condition until they have been examined and con- dition noted by the local freight or express agent. SHIPMENTS— Where no instructions are furnished with order we exercise our own judgment as to method of shipment, i. e., via freight, express, boat, parcel post, etc. All shipments are made in accordance with the regulations of the Interstate Commerce Commission. All parcel post shipments are automatically insured against both loss and breakage under a blanket policy, the small charge for which is included on bills. AGENTS AND REPRESENTATIVES—We have no special agents or territorial representatives and all our traveling is done by members of our permanent staff in Philadelphia. Our wholesale specialties are obtainable throughout the world from regularly established and recognized dealers in laboratory apparatus. SPECIAL ORDER SERVICE—We maintain classified information and prices of many items required for laboratory work and not listed in this catalogue. This information is always available to our patrons upon request. Where it seems more desirable to purchase directly from the original source rather than through our medium, such recommendation is promptly offered. Philadelphia, U.S. A., September, 1921.

y The author’s arrangement for operation
COLD WATERY | includes a laboratory reducing gear 48:1 driven
by a } h.p. electric motor arranged so that the
shaft of the digester operates at about five r.p.m.
The author’s procedure in making sugar tests with
the Rotary Digester is as follows: 100 grams of
chopped bagasse is weighed in a tared cylinder; 1
liter of very hot water is added; the cover, with
the cock closed, is placed in position on the cylinder
and this is then locked on the hub. If ammonia is
used in preserving the material while collecting the
sample, no alkali is added to the digestion water,
otherwise sodium carbonate is added. The cover
is closed and, with the bottom drain open, steam
is turned into the casing. Very little steam is
needed. With the outlet to the drain open, the
pressure is that of the atmosphere. The cylinders
4474 are revolved for an hour in the steam and this is
; then shut off, and the drain is closed; cold water is
now admitted and the revolution of the hub is continued until the sample is cooled. The drain is opened and
the cylinder is removed, dried and weighed.

Metric quantity specifications for items listed and packed on the dozen basis, and vice versa, result
in unnecessary delay in shipment and tend to retard, rather than advance, the universal adoption of
the metric system in commerce and trade. We favor the use of the metric system wherever practica-
ble, but encounter many difficulties in the way of its rapid adoption because of the use of automatic
machines for the making of standard cartons and boxes, and long established practice in trades other
than those connected with the Laboratory Apparatus business and finally, because of many items which
pack better by dozens than by tens. For example, certain articles pack in a carton of satisfactory
shape in three rows of four, rather than in one row of ten or two rows of five pieces.

DIPPING REFRACTOMETER. This refractometer also depends on the observation of the border line
of total reflection in a telescope for method of measurement, but the range of the instrument as compared with
refractometers of the Abbe type is very much less, being nD 1.325 to nD 1.367. Measurements, however, can be
made to 0.2 of a scale division, and under favorable conditions to 0.1, and as the latter value corresponds to 34
to 4 units of the fifth decimal place of nD, the Dipping Refractometer excels in accuracy all other refractometers,
except those of the Interference type.
The Dipping Refractometer is used to determine the refractive indices of fluids, such as alcoholic and
weak acid solutions. In ordinary practical work, the divisions of the scale as read off the ocular give the desired
result of the measurement, although in some cases the reading may have to be converted by means of the tables
furnished with the instrument, into the exact values of the refractive indices. This method of measurement
applies particularly to the analysis of standard solutions and the exact and rapid determination of the concentration
of solutions.
In solutions such as ether, which evaporate quickly, the metal beaker which fits over the prism end of the
refractometer is used. The instrument is then held with the prism pointing up. The beaker, with the metal cap
removed, is securely fastened in place on the refractometer, and the liquid for investigation is poured into the
beaker until the latter is quite full. The cap is then replaced and locked in position. The solution for examination
is now air and watertight, and the refractometer is hung from the wire frame of the bath—with the rack for
holding glass beakers removed—with the metal beaker immersed in the tank bath.
For the investigation of solutions such as blood serum, obtainable only in small quantities, or solutions
such as molasses, too deeply colored to be measured by other means, an auxiliary prism is supplied, which in
connection with the metal beaker requires only a few drops of solution for investigation. In using the auxiliary
prism, care should always be taken to apply enough of the solution to fill completely the space between the two
prism surfaces.

copper bath is mounted in a box made of two layers of asbestos transite with a space of 33 inches
between, which is filled with asbestos air-cell insulation. The wire-wound removable resistance
plate is the same size as the bottom of the tank and serves as a heating unit. The Freas Regulator
controls the temperature of the bath from room temperature to boiling point, with a regulation
of 1 to 5°. When connected with ordinary 110-volt lamp socket, the temperature of the water in
the bath reaches 65° C, but heating plate is wound for 1500 watts and must be connected directly

WATER BATH, ELECTRIC, DeKhotinsky, for constant temperatures, consisting of a copper container
¢'mm thick, heavily nickel plated inside and out, lagged with 25-mm magnesia asbestos, and protected outside by
a sheet of Russia iron. The bath is attached to an enameled cast-iron base, supplied with three nickel-plated rods,
to which may be attached laboratory clamps for supporting flasks, ete. Each bath is fitted with four electric
heating units, three of which may conveniently be added one by one, by means of the switch constituting part
of the bath. The fourth unit is electrically connected to the relay, which is automatically operated by a thermo-
regulator.
OY The thermo-regulator consists of a solid drawn steel tube, brass covered, nickel plated, filled with mercury,
with a platinum contact attached to a regulating cap, by means of which the bath can be regulated and set to the
desired temperature, ranging from the temperature of the surrounding atmosphere to the boiling point of water.
Should a temperature higher than the boiling point be needed, the water may be replaced by ‘‘Crisco,” which
can be used up to a temperature of 165° C, or even higher. For temperatures within 2° of room temperature and
lower, the cooling cell must be used.
A constant water level attachment is furnished with each bath, by means of which the water level can be
regulated within a range of 35 mm, and maintained within 1 mm of the level at which it is set. This bath has a
very good natural circulation, as heat is supplied inside the bath 25 mm from the bottom. When experiments or
research demand a more vigorous circulation and regulation closer than 75° C, a small high-speed Turbine Type
Stirrer No. 9240 can be attached to the bath. This stirrer of 18-mm diameter takes water from the bottom of the
bath at the rate of 5 liters per minute, and delivers it at the top with an energy expenditure in the motor of 15
watts. On the shaft of the circulation turbine is an extra pulley to connect with the glass stirrer in the flask.
9926. Water Bath, DeKhotinsky Electric, as described above; without cooling cell, and high speed turbine
stirrer, but with thermo-regulator, constant water level, 5 ft. of cord and plug, and relay for

diameter, each with copper concentric rings and a support with four clamps. This bath is designed
for use in digestions, as in fertilizer work, and for distillation of inflammable volatile materials, and
similar work. It is intended to accommodate flasks and dishes only, and is not suitable for use with
beakers, test tubes, or other vessels requiring deep immersion. Dimensions, 13 x 13 x 9 inches high.

CONSTANT TEMPERATURE BATH as developed in the experimental laboratories of the Leeds & North-
rup Company, is a simple type of bath without automatic regulation, intended for use with a Beckmann
thermometer reading to 0.01°C. This bath consists of a glass jar enclosed in a polished metallic jacket which
provides an air insulting space around the jar. The removable lid is insulated with cork and carries the thermom-
eter holder, adjustable support for the incandescent lamp and stirring device. A holder A for two test tubes is
also provided. These tubes are partially filled with mercury and in them are placed the amalgamated ends of the
lead wires for connecting to the bridge through the binding posts B. Two insulated connectors run from these
tubes to the mercury tubes of the conductivity cell. This method of making connections is convenient and re-
duces the passage of heat between the cell and the room since both ends of the connecting wires are at the temp-
erature of the bath. Support for the conductivity cell C is suspended across the top of the jar and the cell is held
in place by spring clips. The stirring device is provided with pulley for belt drive, as this method keeps the motor
away from the bath vapor and permits regulation of speed by means of cone pulleys.
4010. Constant Temperature Bath, as above described, consisting of a glass jar 83 by 122 inches, with a capacity
of about 33 gallons, polished metallic jacket, insulated wooden top with binding post connectors,
hangers and tubes for mercury contact, support for electrolytic cell, stirring device, and heating
lamp for 110 volts, with cordjand plug, but not including Beckmann thermometer, electrolytic cell

CONSTANT TEMPERATURE BATH, Freas Automatic. This is sometimes referred to as the ‘‘Small Sen-
sitive Freas Thermostat.” It consists of a glass tank, covered on the outside with horse-hair felt to a thickness of
about one inch and on the outside of this felt insulation is placed a cover of linoleum. A portion of this tank con-
sisting of a strip about three inches wide extending from top to bottom is not covered with insulation and serves
as awindow through which the operator can observe his work. Regulation is by means of the Freas mercury
thermo-regulator consisting of a Pyrex glass regulator tube filled with mercury working through a thermal relay.
Heating is by means of two electric lamps. The stirring device is operated by an electric motor suspended by
means of two springs as shown in illustration. This stirring device keeps the water in the tank in constant and
thorough agitation. The regulator is sensitive to a range of 0.01°C, but in practical work under fair conditions
a regulation within + 0.02°C over a period of five minutes and within 0.05°C for periods of an hour or longer is
easily attained.
4014. Constant Temperature Bath, Freas Automatic, as above described, consisting of a glass tank 15-inch
diameter by 14-inch depth, ten gallons capacity with Freas mercury thermo-regulator with thermal
