.F.FUNDAMENTALPRINCIPLES OF,

PHYSICAL CEHMISTRYBy Prutton & Maron

Case School of Applied Science

This text provides a thorough moderntraining in the essential principles ofphysical chemistry, their effective use,:and their correct application. Its aimis to give the student the sound trainingin the fundamentals of physical chem-istry which will enable him to under-stand the science both in a general andqualitative way and also in its more ex-perimental and quantitative aspects. Itis intended primarily for a full year'scourse inphysical chemistry for studentsof chemistry and chemical engineering,but is readily adaptable to any one-semester course for students in otherbranches of science.

PRINCIPLES OFCHEMISTRY

By Joel H. HildebrandUniversity of CGal f nia

The student is here given a knowledgeof the fundamental concepts of chemis-try without being confused with any

more related matter than is necessary

for his grasp of the subject. The textforms a sound basis' for laboratory work'but does not duplicate information more

easily acquired in the laboratory or lec-ture room.

THE CHARACTERIZA-TION OF ORGANIC

COMPOUNDSBy Samuel M. McElvain

Professor of Chemistry,University of Wisconsin

Prepared both for students and forresearch workers in organic chemistry,this book 'teaches the methods of identi-fication and characterization of organiccompounds and includes laboratory ex-ercises. It contains extensive discus-sions of the chemistry involved in organicreactions used for the identification oforganic compounds. It gives practicalprocedures for carrying out these reac-tions in the laboratory, and includes ex-tensive tables of the physical propertiesof the various classes of organic com-pounds and their characteristic deriva-tives.

SEX AND THE SOCIAL ORDERBy GEORGENE H. SEWARD, Assistant Professor of Psychology, Connecticut College. 295 pages,5 x 8. $3.50

A comprehensive book, filling a serious gap in the litera-ture of the biological and social sciences. Presents a

comparative study of the part played by sex in repre-sentative social organizations from fish to man. Sex isconsistently viewed within the framework of the society

as a whole. Progress from lower to higher forms of lifeis shown to be associated with a shift in the balance be-tween biological and social determiners of sex behavior.Based on experimental data, supplemented by clinicalcases and anthropological field studies.

Exploring and inventing, devising and per-fecting for continued improvements and

economies in telephone service.

TINY GIANT WITH A HISTORY

Long before the war, the men who design yourBell Telephone System were looking for anelectron tube with frequency capabilities neverbefore attained. With it, they could transmitwide bands of telephone messages-hundreds ofthem simultaneously through coaxial cable -economically, and over long distances.They developed a tube which set a new standardin broad-band, high-frequency amplification.So minute that its electrode system had to beinspected under a magnifying glass, the tubecould amplify either the voices of 480 peopletalking at the same time, or the patterns oftelevision. Long-distance, broad-band trans-mission became a commercial reality.

When war came, this tube excelled all others asan amplifier in certain military equipment. Itthen grew into the 6AK5, one of the great littletubes of the war. Besides producing 6AK5'sin large quantities, the Western Electric re-sponded to emergency needs of the Army andNavy by furnishing design specifications andproduction techniques to other manufacturers,of whom at least five reached quantity produc-tion. On every battlefront it helped our shipsand planes to bring in radio signals.Developing electron tubes of revolutionary de-sign has been the steady job of Bell Labora-tories scientists ever since they devised the firstpractical telephone amplifier over thirty yearsago. Now tubes like the 6AK5 will help speedthe living pictures of television, as well as hun-dreds of telephone conversations simultane-ously over coaxial highways of the Bell System.

IMPROVEDEastman Spectroscopic Plates, Type I

The Type I emulsion for Eastman Spectroscopic Plates with Class 0, J, H, G, T, D, B, C,and F sensitizings has recently been improved. The new Type I plates have greatly

increased sensitivity and slightly lower contrast compared with previous plates, with approxi-mately the same granularity.By way of example, SA speeds* are shown in the following table for the new Type I-0 and

1-F Spectroscopic Plates in comparison with previous coatings of these plates. The valuesgiven in the table are on the same basis as the values published in Table I of the booklet Photo-graphic Plates for Use in Spectroscopy and Astronomy (5th Edition, 1943).

One of the most colorful figures in the his-tory of chemistry, Robert Wilhelm Bunsen,was born March 31, 1811 at Gittingen.

The discovery, by Bunsen, of two new alkalimetals (Cesium and Rubidium) in the min-eral water of Diirkheim, was one of the firstresults of the application of the spectroscopeto chemical analysis. He had a genius fordevising apparatus to suit a particular need.Among the pieces of apparatus devised byhim may be mentioned his burner, batteryand filter pump.For over fifty years this genius at Heidelbergproduced researches of the highest order andassisted in the education of numerous chemi-cal leaders.Bunsen 's interests lay entirely in the fieldsof inorganic, analytical and what is nowknown as physical chemistry. His study ofthe cacodyl derivatives extended over sixyears and cost him the sight of one eye. Hewas without equal in the inorganic field.

He lived happily in retirement for about tenyears and died on August 16, 1899 at Heidel-berg.

* Each new development in laboratoryglassware pioneered by Corning Glass

'HWorks has not come as the result ofchance. On the contrary, the knowledgeand skill accumulated over the years-the "know how" in glass technology, indesign and in fabrication techniques-have inevitably resulted in progressiveadvancements and refinements in labora-tory glassware.Trained technicians and highly

skilled craftsmen at Corning are ever onthe alert to apply their ""know how" to produce labo.ratory glassware of uniformly high quality to meet

the demands of industry and science. These men

understand laboratory glassware- the balance ofproperties obtainable in specific compositions-thethermal and mechanical endurance which can bedesigned into the ware-and fabrication techniqueswhich assure high quality, enduring performance andeconomical costs.

Users and Laboratory Supply Houses have playedan important role in helping Corning to apply its"know how" to the development of new and finerlaboratory glassware. Their constant interest andcooperation have been extremely helpful in steeringCorning's efforts into fields of development whichmight otherwise have been overlooked. Their enthu-siasm and encouragement have generously benefitedboth industry and science.
