BOOK REVIEWS MICROWAVE SPECTROSCOPY, by Benjamin P. Dailey and fifteen authors. Volume 55, Article 5 of Annals of the New York Academy of Sciences, 2 East 63rd Street, New York 21, N.Y. Paper, 222 pages, illustrated. 1952. Price $3.00. This monograph consists of 16 papers, each of which deals with the present status of an aspect of this comparatively new and rapidly growing subject. Each chapter is written by a qualified author. The book is in no sense a text or an in- troduction to the subject, and will be of far greater value to one al- ready acquainted with the field than it will be to a beginner. Most of the book is devoted to theoretical and technical considerations, with many indications of the course of future developments. Microwave spectroscopy has been, and for some time will continue to be, of greatest usefulness in elucidating molecular and nuclear structure. However, it is uniquely suited to rapid, highly specific, qualitative analysis of ex- tremely small amounts of certain substances. It is capable also of quantitative work with the same materials, but the difficulties in- volved in this are considerable and are likely to impose strict limitations on this application. One chapter is devoted to qualitative and quanti- tative analysis with the microwave spectrograph. There are few er- rors in the book, and there is sur- prising little repetition in the vari- ous chapters.--A. K. PRESUELL, The Andrew Jergens Co. THE LIPIDS, by Harry J. Duel, Jr., Volume I, 982 pages, 6 X 9 inches, indexed, illustrated. Interscience Publishers, Inc., New York 1, N.Y. 1951. Price I/ 18.50. The first of two volumes deal with the chemistry of the lipids. It at- tempts to correlate the available in- formation on the subject. The author has a logical sequence in his division of the subject matter which makes it easy to follow him. Thus the general characteristics of the fats are first considered, followed by the chemistry of the fatty acids, then the chemistry of neutral fats, waxes, phosphatides, carotenoids and finally the distribution and properties of the vitamins of the A, D, E, and K groups. Tables are clearly conceived and generously used throughout. The presence of squalene in hu- man sebum and the U.S. P. rec- ognition of tocopherols as antioxi- dants for mineral oil are not men- tioned, although the 23 pages de- voted to the treatment of antioxi- dants and fat and oil rancidity is a good condensate. It is obviously impossible to read all of the nearly thousand pages, but in a thorough perusal of the book, no errors were noted. One awaits with interest the second volume that will complete this series. The present one is an excellent collection of data from many sources, often especially adapted for this text. Each page is truely packed with information. 131
