Book Reviews Trace Elements in Food. By G. W. MONIERWILLIAMS. John Wiley and Sons, New York, 1949. viii 511 pp. 13.5 x 21.5 cm. Price $6. The trace elements in food are defined by the author of this book as those elements in food which are present to the extent of 0.005 per cent or less. This includes iron which, while not a trace element in the body, is a trace element in food. Trace elements in food are important because they may be toxic or injurious; they may aid in the catalytic destruction of other vital substances, i.e., copper and vitamin C; or they may aid in causing off -color and off -flavor in food. A few of the toxic trace elements, like selenium, may actually occur in the natural foodstuffs occasionally. Other elements like arsenic, lead, tin, and mercury are more a p t to get in by way of industrial processing or spraying for insects and rodent control. The toxicology, biochemistry, and analytic chemistry of these elements are extremely important t o the food technologist. It is fortunate that the author has seen fit t o bring all these data together in one book. Since the pharmacist must deal frequently with natural substances, he will often find a lead here in the control of his products, when trace elements may affect stability, color, or flavor. In this book, each chapter discusses one element. If the element is essential for life, this fact is brought out with as much detail as is practicable or available. In such cases biological availability, minimum requirements, absorption, retention, excretion, and similar properties are brought out. The toxicity and its mode arriving in the foodstuffs are next taken up. The ability of foods t o corrode metals is discussed if such action is of significance. The effect of the element on taste and color of individual foods is discussed when pertinent. Analytical methods (which are, by their nature, micro) close the chapters. References appear a t the end of each chapter. To those interested in any phase of food tecnology, this is a n important and useful book.

New Gould Medical Dictionary. First Edition Edited by DRS. HAROLDWELLINGTON JONES, NORMANL. HOERR,and ARTHUROSOL. The Blakiston Co., Philadelphia, 1949. xxviii 1294 pp. 17 x 25 cm. 252 illus. Price $8.50. The New Gould Medical Dictionary is the excellent answer to a long-felt need. It is the first completely new unabridged medical dictionary issued in the last thirty-eight years, and the first medical dictionary t o be built on modern lexicographic methods. Planned from the beginning as a new entity, this book is the product of a n editorial board and distinguished staff of more than one hundred contributors. Thousands of new entries from all branches of medicine and allied sciences are presented. New terms, as well as changes in usage, are given and pronunciation is indicated by a simple system of phonetic respelling. Much of the illustrative material is entirely new and in full color, and the tables of hormones, vitamins, enzymes, etc., are in a section of their own for the first time. Legibility is of a high degree of excellence, due to careful choice of type styles, and subentries are aligned for the first time. All entries are presented in a single inclusive alphabetical list. This book should mark a new era in medical dictionary making. Dr. Arthur Osol, one of the editorial trio, represents the pharmaceutical and chemical field, and because of the meticulous attention given t o entries in this area by him, members of the pharmaceutical profession will find the dictionary particularly valuable. The book is sturdily constructed and will stand up under long continuous use. The paper, binding, and printing are of the usual high degree of excellence found in books published by the Blakiston Company.

Industrial Toxicology. By LAURENCE T. FAIRHALL. Williams and Wilkins Co., Baltimore, 1949. xi 483 pp. 15 x 23 cm. Price $6. Industrial Toxicology is a reference manual describing the toxicity of both old and new substances used in industry. The author describes, under each listing, the characteristics, industrial uses, toxicity and analysis and includes a carefully selected list of pertinent references. Many of the substances covered are of interest pharmaceutically-iodine mercury, acetone, benzene hexachloride, carbon tetrachloride, chloroform, dibutyl phthalate, 2,4-~-ethyIacetate,ethyl alcohol, ethyI chloride, formaldehyde, methanol, nitroglycerin, oxalic acid, phenol, picric acid, isopropyl alcohol, methanolamine, and turpentine to mention a few. The conciseness of its organization makes this reference a valuable book t o industrial hygienists and t o all who have occasion t o refer t o this kind of information.

Radioactive Measurements with Nuclear Emulsions. By HERMANYAGODA.John Wiley and Sons, New York, 1949. lx 356 pp. 13.5 x 21 cm. Price $5. The detection of radioactive particles by means of exposure to photographic emulsions is a very useful technique in the radioactivity field. Dr. Yagoda has reviewed and brought together the methods of applying such techniques. Specialists in radioactivity will find this book a very useful guide to such methodology. The bibliography contains about 700 items making up a nearly complete list of publications in this field. Since this is an era of elaborate electronic recording apparatus, many will be pleased to note the value of such a “primitive” device as a photographic plate.
