This eye spc

When trouble is hidden in a blur of speedtoo fast to see, the cause is hard to find.Here's the way to get the answer in a hurrywithout costly, tedious cut-and-try experi-mentation or theoretical analysis.With the Kodak High Speed Camera,

you can take up to 3200 clear pictures asecond on 16mm film. When projected atnormal speed, the film shows action slowedas much as 200 times-makes visual analy-sis quick and easy. And the films are avail-able for study over and over.This high speed "eye" is daily solving

complex problems of design, production,and product performance-problemswhere usual methods of analysis would beslow and costly. One manufacturer pro-jects high speed movies within two hoursafter they are taken-the solution to aproblem is on the drawing board the samemorning it is discovered. We'd be glad tosend you, with our compliments, a foldershowing how this company uses the KodakHigh Speed Camera so effectively.

NICOTINIC ACID HYDRAZIDE

for investigational use

Smith-New York is a producer of fine chemi-cals for industrial laboratories, plants, univer-sities and government laboratories . . . special-izing in the production of chemicals not ob.tainable elsewhere. Smith-New York has pro-duced many new chemicals of wide interest.The association of some of our scientific per-sonnel with much of the early antibiotic de-velopment in this country has led to our deepinterest in the progress of Isonicotinic AcidHydrazide as an antibiotic. In consequence weare departing from our usual production pol-icy and are producing this material to advancelaboratory study while the supply is short.

YEARS OF RESEARCH by the statistical staff of the Metropolitan LifeInsurance Company have gone into the making of this 460 fact-packedencyclopedia on a whole variety of health problems. Here are abundantfacts about birth, marriage, health, longevity, and the factors influencingthem. The material is presented in convenient question and answer form.1951.-$4.95

A Course inCollege Chemistry

V. R. Damerell

HERE IS A COMPACT, LIVELY BEGINNING TEXT with a limited ter-minology, original and provocative analogies, and clarifying illustrationsdesigned to hold the interest of the non-chemistry major while giving hima solid grounding in the science. A few supplementary assignments, fur-thermore, will enable any preprofessional student to complete his profes-sional training at the freshman level. Dr. Damerell finds that the studentdoes much better with an approach grounded in concrete examples fromhis environment-his own body, his garden, and the materials he en-counters in everyday life. It is to give these students an understanding ofchemistry, and through it, of science, that he has written this text. Readyin May.
