do with the thoo~ycovering the mechanism of induced nuclear reactions. This book, written by one of the foremost theoreticians on nuclear struotutt, includes the most recent thought,^ on the particular topics chosen, and the treatment is concise. I n addition, the fimt six short cha.pters (22 pages) provide an excellent descriptive treatment of general basic nuclear properties and processes. However the reading of most of the book will be most rewarding t o t,hose who have some facility with the mathematics and concept,s of quant,um mechanics. An l b p s g e appcndis consists of a "Table of Nuclear Species." I. PERLMAN U ~ r v e n s l ~OF r C*LIIORNI* Benmbsr. CAGIPORNI*

"POWDER METALLIIROY" i~ a book that, in the author's words,
"
. . . is not intended to give a. complete picture of powder metal-
lurgy." This is certainly truo. Chapters 2 and 3 (25 pp.) on principles and methods of manufacture leave much t o be desired in the discussion of the subjects indicated, chiefly because of extreme brevity and lack of numerical data. Chapter 4, Metalporders and their applicittions (11 pp.), is eatiemely brief and rives token coveraxe of the subieet. Chanters 5 t,hrounh -10 n-n ) - 11 ~ 17 - -rr-, give tabular and graphical correlrttion of product physical praperties with the principal manufacturing process variables such as particle siae, compacting pressure, sintering temperatuie, cold and hot working, and composition. These correlations, in most cases reproduced from current literature on the subject, represent a good summary for ready reference. Chapters 11 and 12 (130 pp.) constitute a fairly comprehonsive bibhography on the suhiect of ~ o w d e metallurev. r

THE PURPOSE of the author was to writ,e a short, easily understandable textbook which, in spite of its brevity, should not give a, too superficial survey of physical ehomistry. In this respect he has been wecessful, for alt,hough the book is much shorter than oomp&rahl.ble American texts, the treatment is usually very thorough. The mat,erial is divided into twelve sections with the following titles: Introduction (6 pages): Influence of Temperature on Physica-Chemical Systems (39 pages); First Law of Thermodynamics (32 pages); Second Law of Thermodynsmies (24 pages); Dr?terminat,ion of A,.,, in Chemical Reactions (31 pages); Dilute Solut,ions (42 pages); Electrolytes (71pages); Dcnendence of Chemical Eauilibrium on Temwrature (30 naeea):
