BOOK REVIEWS inevitable exponent of wrong sign and dsngling participles does occur (pages 116 and 158, for example). Considerable recent work ia included in most chapters as evidenced by the number of references since 1950. Suggestions as to the course of future work enhance the value of this volume for workers in the general field. There are numerous references to Volume 1, few specific in nature. In general, each chapter is self-contained, often with repetition of material, a feature justified by the editor on the basis of completeness of s subtopic. Volume 2 will, therefore, stand complete as a useful reference book without Volume 1. If Volume 1 was purchased, this volume ought to be used also. EMERSON E.

Val. 11, Organic Applications." The fifth English edition of the latter appeared in 1956 as "Spot Tests in Organic Analysis." In %pot Test8 in Inorganic Analysis," the fifth English edition, more than a hundred new tests and applications have been added and many old tests have been improved. The hook contains much new material published for the first time, most of it being experimental work conducted in the author's own laboratory. Experimental details and explanation of the chemistry of the tests have been brought up to date. The arrangement of the material and the description of tests is the asme as in the previous edition. The book contains seven chapters: Chapter 1, Development, Present State and Prospects of Inorgrtnie Spot Test Analysis (26 pp.); Chapter 2 (by P. W. West), Spot Test Techniques (30 pp.); Chapter 3, Tests for Metals, Cations and Anions of Metallo Acids (201 pp.); Chapter 4, Teats for Acid Radicals: Anions (103 pp.); Chapter 5, Tests for Free Elements (22 pp.): Chapter 6, Systematic Analysis of Mixtures by Spot Reactions (45 pp.); and Chapter 7, Application of Spot Reactions in Tests of Purity, Examination of Teohnioal Materials, and Studies of Minerals (88 pp.). At the end of each chapter is an extensive list of references to the literature, the total being more than eleven hundred. Chapter 7 is followed with a tabular summary (18 pp.) of the limits of identification attained by spot testa for (1) c& ions, (2) anions, and (3) free elements.
If a. reaction can be carried out in different ways, the limit of identification is given for the most sensitive procedure. Author and subject indexes conclude the book. R. E. Oesper, well-known tranalator of Feigl's books, is to he congratulated far making "Spot Tests in Inorganic Analysis" available in clear and concise English. Printing and paper are good and the book has an attractive flexible cloth binding. This volume, together with its companion volume on "Spot Tests in Organic Analysis" (1956), is s. useful and uptodate source of information not only to analytical chemists but also to organic chemists, phclrmilceutical chemists, biologists, and mineralogists, as well rte t o advanced students in r.hemist,rv. Re. sesreh workers in analytical ohemistry will find these two volumes stimulating and helpful. JOHN H. YOE Uniuersity of Virginia Chadottesville Nouveau Trait; de Chimie Minirale. Volume 4
