geties, n.hirh is devoted largely to a diecussion of high energy phosphate and srdfur compounds, is supplemented by an appendix in which methods of calculating free energy changes are presented. This book concludes with chapters on energy metabolism in man and on chemical kinetics. This baok is well written and rovers quite thoroughly the topics considrrpd. The style is pleasing and the tent seems to be quite free from errors. Exercises are given a t the ends of the chapters in thc first half of the book. This should be a useful text for mpdir:d students n h o desire a more thorough mrdwstanding of the phy~ieslchemical basis of biochemistry- than is found in many medical school biochemistry texts. In addibion it might well serve aa a text f w sn undergradi~atecourse in physical chmmistry for ptwmdical students. l R T H U R H. LIVERMORE R r r o COL,.~*E P o R T L * ~onzoos ~,

THE stated purpose of the authors of t,his survey is to consolidate the entire fipld of organic analysis from one point. of v i e r , to describe the available tools, their fundamental principles and techniques, their correlation, bheir application and thp interpretation from the viewpoint of thp organic chemist. A list of chapter titles gives the subjects covered: Elemental Anslysis, Ftlnrtion8.1 Group Analysis, Patentiomet,rie Tit,ration, Ahsorption Sprrtroscopy, Freezing Point, Polsrographir Analysis and Amperomctric Titrstions, X-Ray- Difisetian, Refractive Index a n d Density, Methods of S~paration,Speciaised Appraneheh. Each chapter contains a very brief discussion of theory, some applicstions s n d nn experiment illrtstrltting one of the terhniqoes. In addition t,here are references t o standard texts and procedures c a v e r ~ d The authors achieve their purpose in surveying the entire field but do not discuss the topics thoroughly. For examplc, both Kjeldahl and Ilumas methods nr? mentioned, hut no indication as t o the compitretiv~advantages and general applienhility of each mpthod is given. I f this baok were t o bp used as a. text, thr inst.ructor would find i t necessav to snpplement thc theory and to obtain adilibional exp~rimentsfrom other sourrrs. The illristrrttive problems are of considerable vnhw as examples but no adriitional prohlems with experimental data are supplied. This book is recommended as a supple ment t o the organic analyst's library, hut i t will not serve as a rourse t,ext. J. D. R E I N H E I M E R C O L L E ~OEF n-OOSTFR WOasvEn. O"l0
