a new kind of annual volume...

1949 CURRENT THERAPYj |-HIS brand new annual volume is completely different from any

other medical book ever published-different both in concept andin content. It provides a detailed and unbiased report on the very

latest treatment-today's treatment-of every disease and condition likelyto be encountered in general practice, from abscess to yellow fever, fromthe common cold to multiple sclerosis.The material for 1949 Current Therapy is gathered in this way: the Boardof Consultants (listed below) selected 236 American authorities, each ofwhom is using (in the opinion of the board) the best treatment known tomedical science today for a given disease. Each authority thus selected thenwrote down-especially for this book-a concise and factual description ofthe method he is using. This is truly today's therapy!

Note that the information you get in 1949 Current Therapy is not ex-tracted from the literature, is not in any way biased or experimental. Everymethod of treatment explained here is being used today by the authority4'h/o describes it for you.

PRECISION REGISTER specially made forthe United States Navy . . . used for pre-cision propulsion measurements. Has -

inch dial, and indicates up to 100 im-pulses per second.

yclotron Specialties Impulse Registers wereoriginally designed to meet the exacting re-quirements of radio-activity research workers.Their outstanding performance has attainedfor them acceptance in nearly every scientificfield and today, many special types are in useby scientific workers throughout the world.

Cyclotron Specialties Registers are unique intheir ability to operate at exceptionally highspeeds with complete -accuracy and withoutadjustment or maintenance. They are unex-celled for high speed impulse recording andmechanical operations requiring counting inprecise quantities.

A NEW LINE OF PYREX HIGH VACUUM STOP COCKS

The answer to leakage in high vacuumoperations-these stop cocks have beendesigned and fabricated to meet the mostcritical requirements. They are ruggedlyconstructed with hollow stoppers and thelonger barrels and stoppers providegreater surface area reducing the possibil-ity of leakage. Special abrasives used forgrinding assure tight joints. The arms aremade of reinforced seals. Each stop cock

is individually tested. This all adds up todependable service under high vacuum.PYREX brand high vacuum stop cocks

are available in four different styles,oblique bore, oblique bore with vacuumcup, right angle side arms and offset sidearms with bore sizes of 2, 4 and 6 mm.Eliminate leakage problems by ordering asupply of PYREX brand high vacuum stopcocks today.

Wing vibration, nimbly controlled, keepsthe humming bird in flight, enables it to feedwithout alighting.

Electric vibration is the essence of tele-phone transmission. Voice, music, pictures,teletype - no matter what type of signalthe story is told by the frequency and strengthof not one, but many vibrations.

Learning how to control electric vibrationsto pin-point accuracy has been one of thebasic jobs of Bell Laboratories scientists intheir development of the "carrier" art whichenables the sending of many more conversa-

tions over existing wires. Among their inven-

tions have been oscillators, modulators,filters, coaxials, wave-guides, and radio lenses.

Constantly Bell Laboratories scientists dis-cover new and better ways to control andadapt electric vibrations by wire or radio tothe needs of the telephone user. Theirpioneer work in this field is one importantreason behind todav's clear, dependable andeconomical telephone service.

Of hard glass, nearly pure whitein color and guaranteed against

corrosion in any clixate.

7030. 7036-A.

MICRO SLIDES, Non-Corrosive, Red Label, A.H.T. Co. Specification. Of hardglass, nearly pure white in color and guaranteed against corrosion in any climate.Thickness varies between 1.18 and 1.30 mm, with an average of 1.23 mm.

The glass from which our Slides are made is of superior quality-particularly as to surface finishand uniform thickness-so that the two grades are identical as to stability, optical quality and plane-ness of surface, the following classification depending upon freedom from bubbles, pits, nicks and striaeand in the finish of the edges:

Special Slides. With polished edges, slightly beveled on the three-inch edge, and with rounded corners.Entirely free from bubbles, pits, nicks and striae. Individually selected and offered as, in- ourjudgment, the best micro slide now available.

Clinical Slides. With polished edges and rounded corners, i.e. identical with Special slides except forthe omission of the slight bevel on the three-inch edge and that selection is based upon the platefrom which the slides are cut, rather than upon the individual slide, so that an occasional slide maybe found with a slight defect. Offered as a superior slide for general work.

Some Micro Slides show cloudiness near the edge-and sometimes.throughout the usable surface-as a result of the deposit of powdered glass in solution from the edge-grinding process, with too rapiddrying and insufficient cleaning thereafter. Our Slides are free from this defect.

TWO IMPORTANTSPECTROGRAPHIC TOOLS FOR

HIGH VOLTAGE EXCITATIONWITH SAFETY* With the B&L Safety Arc & Spark Standyou can use high voltagefrom 2,000 to 5,000 at

2 to 10 amperes for excitation with safety. Allparts carrying current are enclosed in a cylin-drical chamber, thoroughly insulated andtotally inaccessible from the outside except

by one opening. When the door is open elec-tric current is automatically shut off. In addi-tion tocomplete safety,analysis by thecathodelayer type of illumination is facilitated.

POWDERS TO PELLETSIN A JIFFY

* Quickly turning granular materials, hack-saw dust, drill chips and the like-into solidpellets for spectrographic analysis is the func-tion of the B&L Briquetting Press. The use ofthis ruggedly built machine also makes pos-sible analysis of such substances as thin sheetmetals and fine wires, fireclay, coal ash, rocksand minerals, plant and animals tissue ash,etc. Pellets formed will withstand arc andspark excitation without loss of material.
