I n the preface to this hook the author states his approach " . . . a course in quantitative analysis is foremost, a course in rhemistry, . . . the suerepsful pursuit of the suhjert requires an understanding of the chemical principles and reactions, as well as of the numerical relationships serving as the basis for caloulations from the anlybical data." The author has followed the indicated path well and has presented a hook which i r eleilrlv a course in ohemistw as indicated by t,he' number of ionic equations and chemical formulas presented, and is a strldy of the numerical relationships as indicated by the number of problems (apI,'arimately 400)included. The book consists of five parts. Part I on Fundamental Principles consists of 15 r h a ~ t e r s204 , pages, covering scope and a i m , the balance, mass action principles, reliability of measurements, separation methods, and ~recipitation phenomena. Part I1 on Gravimetrie Methods consists of 10 chapters, 81 pages covering the chemistry and calculations of a number of different gravimetrie methods. Part 111 on Titrimetric Methods consists of 11 chaptew, 200 pages, covering measurements of volume, calculations of titrimetric snalypis, neutralization theory, redox theory, and the chemistry of neutralization, redox. precipitation, and complexation titrations.

It will he diffioult to understand how anyone owning the earlier version of Professor Lingme's outstanding moncgraph will he able to resist this second edition. The material which made the first volume invaluable to students and teacher8 of modern analytical chemistry is still present and well revised. In addition, the present book is truly enlarged and the new topics src treated in a thorough and comprehensive manner. It is hardly fair to callit s. second editionthis is s, new hook and one whioh should he on every analytical chamist's shelf. I n fact, quite a wide variety of chemists, student and graduate, could profit from Lingane's lucid and forthright interpretation of the emf of galvanic cells, controlled potential methodology, etc. Among the new material, Chapter 2 on common electrical measurements is a welcome addition. Straightforward and simple in approach, it nevertheless serves well as a background for those interested in the experimental techniques of electrcanalytical work. The section on polaragmphy fits its intended purpose as an introduction to the esrdinal principles of this subject. The chapter on amperVolume 36, Number 7, July 1959
