O&TANYAn Introduction to Plant Science. By W. W. ROBBINS and T. E. WEIER, bothat the University of California. Covers the basic facts of plant science and theirrelationships to agriculture, medicine, and many other fields. Nearly 500 illustra-tions are used to clarify details in the reading matter. The authors empha.izerecent discoveries in plant anatomy, photosynthesis, respiration, genetics, Awterrelations, growth substances, chromosome structure, and many other subjects.They avoid highly controversial viewpoints and follow the generally accepted sys-tem of classification.' Ready in April. Approx. 418 pages. 490 illus. Prob& $5.00.
PRINCIPLES ofIONIC ORGANIC REACTIONSBy ELLIOT R. ALEXANDER, University of Illinois. Presents the reaction mech-anisms which seem plausible for a number of the most important ionic organicreactions together with the chemical facts which support these ideas. This book.sets down the fundamental processes from which a number of seemingly different-organic reactions can be constructed. It explains their scope and limitations and thenillustrates these principles by a number of common examples. In accordance withits stress on the organic chemist's point of view, Principles of Ionic Organic Reac-tions is non-mathematical and non-physical in presentation. Ready in May. Ap-prox. 286 pages. 212 illus. Prob. $4.50.
EXPERIMENTAL DESIGNSBy WILLIAM G. COCHRAN, The Johns Hopkins University, and GERTRUDE.,M. COX, University of North Carolina. This new book presents a. full accowut &:experimental design: the ways to plan and conduct comparative experiments so. theywill provide specific answers to the scientific questions under inwstigation. Earlychapters cover the logical principles that govern sound experimestation; later ones'contain a detailed'account of the experimental designs that have'been developed.A book in the WILEY MATHEMATICAL STATISTICS SERIES, Walter A. Shewhart,Editor. Ready in March. 454 pages. Prob. $5.25.
FUNDAMENTALS of PHYSICAL CHEMISTRYfor.PREMEDICAL STUDENTSBy H. D. C1IOCKFORD and SAMUEL B. KNIGHT, both at the University ofNorth Carolina. Designed for a one-semester course without mathematics, thisbook gives an. understanding of seven main aspects: 1) the physico-chemical methodof approach; 2) the gaseous and liquid states of matter; 3) solutions-electrolytesand nonelectrolytes; 4) the mass law, with particular reference to solutions ofelectrolytes; 5) electrochemistry sufficient to teach the theory'and use of electricalmethods for determining hydrogen ion activity; 6) the colloidal state; and 7)atomic structure, radioactivity, and nuclear chemistry.

An Atlas of
Cat AnatomyBy HAZEL E. FIELD d MARY E. TAYLOR. A mod-ern laboratory visual aid which demonstrates throughphotographs and drawings the structures which the stu-dent will dissect. It shows the animal as the studentactually sees it before him. The book is so arrangedthat the illustrations may be propped up in front of thestudent as he dissects the specimen. A brief text relat-ing directly to the plate appears opposite each illustra-tion. Particular attention is paid to correct terminologyand the relatioxips of part to part. Intezde4 foz use
in all courses in which the cat is used for dissection-primarily comparative anatomy, human anatomy, andother biology courses.

OF MICE AND STRAINSA major problem in experimental chemo-
therapy of tuberculosis has been to find a strainof mice not only of high susceptibility, but alsoas uniform in response as possible.
For the past few years the Squibb Institutefor Medical Research has carried on studies di-rected toward this end. The results of thesestudies were published in a recent report.*Of seven strains tested, Carworth Farms'
strain of albino mice, the CF#1, was selectedas being the most suitable for use in a standard-ized test for the anti-tuberculosis activity ofcompounds.
It.- has always been a fundamental aim -ofCarworth Farms to aid in the advancement ofmedical research. We take pride in the smallpart our CF# 1 strain of mice has played inassisting in the fight against tuberculosis.

Pocket Encyclopedia OfICTpt -OMI ENERGY
By FRANK GAYNOR
THE PURPOSE of this book is to present a comprehensive collection of brief ex-l planations and definitions of concepts and terms in the field of Nuclear Physics andAtomic Energy to the scholar, reseacher, teacher, librarian, student and intelligent lay-man.
Also included are thumbnail biographical sketches of outstanding nuclear physi-cists and chemists-in itself a pocket Who's Who of atomic science. Another supple-mentary feature is the listing of German equivalents for a great many of the terms dis-cussed.
Over two thousand entries, with numerous charts, tables and illustrations."The book is well planned, well executed, and it reveals a profound knowledge of
the subject covered. It is a must for every physicist as well as every intelligent laymaninterested in atomic science."-Dr. Sydney Baruch, Consulting Engineer of the SpecialWeapons Division, U. S. Air Force; Inventor of the anti-submarine depth bomb.
