BOOK REVIEWS section on molybdenum. is treated by
J. Auhry. Chretien and Freundlich have contributed the section on tungsten, but a n additional section by Malaprade appears in it on the heteropolyacid derivatives of molybdic and tungstic anhydrides. It is felt that the latter should have been separated by the editor so that several pages on compounds of molybdenum would appear under that element rather than in the section under tungsten. This volume has none to rival it in comprehensive modern treatment of the three elements under one cover. ROGERV. KRUMM University of Florida Gainsville

This book is a supplementary volume to Volume 2 of the third edition of the camprehensive four-volume treatise on "Colorimetric Methods of Analysis (194854)." It covers the work that has appeared since the date of publictttion of Volume 2, "Inorganic Determinations" (1949) up to January 1956 (plus a few important later ones) and includes for the first time flame photometry with improvements in burners, the application of photomultiplier tubes, and detailed procedures on this important extension of "colorimetry" to include the color of flames. The authors' deoision to bring the third edition up to date by the additions of supplementary volumes is a wise and practical one, in view of the vast amount of new material that is appearing in the literature. Even so, Volume 2A is almost as large as Volume 2, though it covers a period less than a decade and ai necessitv must lae several wars he-
them containing only one or two pages because of lack of new or improved methods dealing with the respective topics. The treatment of subject matter is the same as in Volume 2, namely, beginning with lead (Chapter 1) the metallic elements are taken up individually acoording to their analytical chemistry grouping and ends with magnesium (Chapter 45). Then follows chapters an the nonmetals and their radicals, the last three chapters dealing with oxygen and water, peroxides, and ozone. Each chapter begins with a, brief introduction on the new or improved methods, followed by directionsfor preparing the samples, the reagents, and the standards. Details of procedures include the means of removing interfering suhstitnces, avoiding errors, and methods of calculation. In order to avoid unnecessary duplication, frequent page references are given to Volume 2. In addition, there are

BOOK REVIEWS more than 3100 references t o colorimetric 2nd photometric methods of inorganic analysis that have appeared in the litemture since the publication of Volume 2. The hook is replete with formulas, tables, and illustrations that make d e a r the details of procedure and calculrttion. There is a complete suthor index nnd a detailed subject index. Printing, paper, and binding are good. This volume plus the four t h a t comprise the third edition of "Colorimetric Methods of Analysis," presents a n exhaustive and authoritative compilation of great value to analytical chemists, both aa a. r~ference work and a s a guide to the literature.

This is the second edition of s. very excellent biochemistry text. The review of the first edition may be consulted for further details. (J. CKEM. EDUC., 31, 50 (1954).)The second edition includes the advances in biochemiatry dwring the fiveyear period since the publication of the first edition. This material is not presented in encyclopedic form, hut is evaluated by the authors in exoellent fashion. This continues to he one of the outstanding textbooks of chemistry for instruction in biochemistry a t the graduate and advanced undergraduate level. ARTHURH.

Dendritic Crystallization
D. D. Saratovkin. Translated from the Russian by J . E. 8. Rradle?~. Consultants Bureau, Inc., New York, 1959. 120 pp. Figs. and tables. 15.5 X 23 cm. $6. This Russian translation adheres olosely to its title and has, in. general, a more practical rather than a theoretical emphasis. The translation is not always even, but the rough spots do not detract appreciably from comprehen~ibility. There are many illustrations, both photographic and line drawing, including a large number of photographs through stereoscopic microscopes. The book seems t o he a rather thorough review of the Russian contributions t o the observstion and interpro tabion of dendritie crystsllisatian.
