New (4th) Edition

Hadley's Veterinary ScienceThe New (4th) Edition of this standard work is completelyup-to-date in every way. It discusses all phases and aspectsof veterinary science in thorough and understandablefashion. The first part describes the structure and functionof the animal body, while Part II explains the nature, causes,symptoms, treatment and control of the more commondiseases, plus immunity and livestock sanitation.

In this New (4th) Edition the emphasis is on dairy cattle,and there is new information on meat and milk hygiene,animal breeding, etc.

By FREDERICK B. HADLEY, D.V.M., formerly Professor of Veterinary Science, Uni-versity of Wisconsin. 614 pages, 51" x 75", with 100 illustrations. some in color.

Sisson's Anatomy of AnimalsOne reviewer said of this book: "No description ofSisson is called for. It is one book that stands withouta competitor...

That is high praise, but merited, because the usefulnessof this book extends to the entire field of mammaliananatomy. It covers the anatomy of the horse, ox, dog,pig, sheep and chicken. The 770 illustrations virtuallycomprise an atlas.

CHEMICAL INSECT ATTRAC-TANTS AND REPELLENTS

By Vincent G. Dethier, Ph.D., Associate Professorof Biology, The Johns Hopkins University.The role played by chemicals in attracting and re-

pelling insects is of vast economic importance. Here,

for the first time in book form, is the story of testsdeveloped and employed during the war by the Amer-ican, British and Russian armed forces. Botanical,chemical and physiological aspects are fully con-

sidered. A valuable book for the health officer, theindustrial chemist and the worker in pure science,the experiment station and in the field.

LECTURE EXPERIMENTSIN

CHEMISTRYBy G. Fowles, M.Sc., F.C.S., Latymer Upper School,Hammersmith, London.

No science teacher can read this book without a

surge of appreciation, almost gratitude, toward theauthor. In it are distilled the results of a lifetimeof experience, years of writing labor. The book isunique in its recognition of the cultural value ofchemistry. Using only the simplest of apparatus,found in every laboratory, the book presents 607demonstration experiments which can be concludedin a 45-minute lesson period. A basic and inspira-tional book for the teacher of high school students,older students in vocational courses, and students inagriculture, domestic science, biology, mining andrelated subjects.

andEdgar P. Slack, Professor of Physics

both of thePolytechnic Institute of Brooklyn

PHYSICS, the widely used textbook for college students majoring in science,technology or engineering, has admittedly led the field for more than tenyears. Though much new material has been added and many revisions made,this new Third Edition still retains the splendid clarity and teaching featuresof the earlier editions.

What's New in This NEW Edition-New Material has been added on the gasturbine, electric circuit analysis, the betatron, frequency modulation, radar,effect of compressional waves on aircraft, vapor lamps, the sniperscope,Schmidt optical systems, and nuclear reactions. Furthermore, nineteen topicshave been revised to conform to the latest scientific information.

RADIOLOGY PHYSICS(In the NEW Second Edition)

byPROFESSOR JOHN KELLOCK ROBERTSON

Head of the Department of PhysicsQueen's University, Kingston, Canada

FOR MEDICAL AND PRE-MEDICAL STUDENTS and RADIOLOGISTS, hereis a book which clearly explains the relation of nuclear physics to radiology and abook which provides a standard text for a second physics course for such students.With the increasing importance of the release of nuclear energy to the medicalsciences, there is recognition of a need for more physics courses for all medicalstudents. As a text for such courses, RADIOLOGY PHYSICS (Second Edition)would seem indispensable.

IMPORTANT REVISIONS AND ADDITIONS:- New material on isotopes and their energy absorption, and the use of

separation, infra-red and ultra-violet Geiger-Muller tubes and photographictherapy, the betatron and pair pro- emulsions for examination of radiations.duction. - Careful, but understandable explana-

- Explanation of the Rutherford and tions of uranium fission, atomic piles,r.h.m. units in radio-activity.

only inches of sound!

When you talk by telephone, far or near,the actual sound travels much less than whenyou talk across the room!

That's because the telephone system car-ries not sound itself but an electrical facsim-ile ofsound. When you speak into a telephonetransmitter your voice is converted intoelectrical vibrations which are not changedback into sound until they reach the receiverdiaphragm.

Conversion of sound into its electricalequivalent, through the invention ofthe tele-phone, opened the way to the measurementof sound by accurate electrical methods. Indeveloping means to make the telephonetalk farther and sound clearer, the scientistsof Bell Telephone Laboratories had to de-velop the tools for sound-wave analysis andmeasurement.

The condenser microphone, the wavefilter, the amplifier-each the product oftelephone research-have helped to revealthe structure of sound as never before. Eachhas helped to build the world's finest tele-phone system.
