formulas are all that an organic chemist could desire. The yield is frequently given in the reactions outlined. The too few diagrams of apparatus are well done. Thought-provoking questions and reading references are given a t the end of each chapter. Cross referencing is good. Quotations from the literature and the nationality of authors are given frequently. Interesting historical notes, explanations of the derivations of chemical names, the names of authors of important reactions together with the year, the addition of commercial names and processes, are advantageously mentioned. There are a great many useful tables of compounds with their structures and physical constants. and there is a very good index. In a hook of this type one might look for a feature not usually found, if a t all, in any textbook, and that is how to pronounce chemical names. It is hoped the authors will consider such an opportunity in later editions. I t is interesting t o note that the authors in some cases follow the older method of the Geneva system of nomenclature by using terms like butene3 and butanol-2 instead of following the later American Chemical Society procedure, 2-hutene and 2-butanol. The only typographical error found in rather extensive reading of this excellent and authoritative book is the spelling of ethylidine for ethylidene (p. SO)! HARRYL. FISHER U.S.

PLASTICHORIZONS (Science for War and Peace Series). H. B. Wcil and Victor I.Anhorn, Gulf Research and Development Company, Pittsburgh, Pennsylvania. The Jaques Cattell Press, Laucaeter, Pennsylvania, 1944. 161 pp. 16 figs. 13.5 X 19 cm. $2.50. The emergence of plastics into the realm of everyday life has necessitated the publishing of a book that would bring plastics out of the status of magic and mystery and put them into the class of realism. "Plastic Horizons" fills this long-felt need for s comprehensive, yet general book, sufficiently nontechnical for the general public, but detailed enough to be informative. From house numbers t o kitchen sinks, our homes of the futuse may he plastic dwellings. "Expandable water pipes which do not burst when water freezes in them, window screens which can be mounted and rolled like window shades, and coated wall paper which can be cleaned with a damp cloth, are some of the intriguing possibilities offered to tomorrow's America. The authors do not predict a wholesale and immediate conversion to plastics, hut a gradual utilization and substitution of plastics where their superiority has been scientifically established. Conclusive evidence is being demanded by both the plastic manufacturers and the consuming public before heretofore readily accepted articles are discarded for the relative newcomer, plastics. The subject matter in "Plastic Horizons" is divided into five sections; the first chapter is an interesting, well-balanced, technical and semitechnical discussion entitled "What Are Plastics!" Interwoven around a slight historical introduction and chemical discussion is a well-written chapter on the types of plastics. Included are the early plastics, hakelite, and phenolic resins, the newer plastics such as the vinyl resins, polystyrene, saran, acrylic resins, and many others. The chapter is augmented with diagrams illustrating compression molding, injection molding, extrusion, and lamination. The second chapter, "Plastics and Our Modern World," discusses the astonishing increase in plastic and resin production during the period from 1927 t o 1941. Figures that would bring the production record up t o date come under the category of military secrets. We can imagine, however, that these figures would he phenomenal, for the growth during the "test tube" era of peace was staggering, while under the "pilot plant" era of war

it would be astronomical. The raw products used in plastic manufacture, among them wood and cotton, can largely be grown in our forests and on our farms. The science of "chemurgy" where the farmer works hand in hand with the manufacturer is made possible by plastic manufacturers. Current interest in plastics is well brought out in Chapter 3, "Plastics I n A World At War." Uses of plastics in ordnance, sea, and air are some of the timely subjects mentioned. A fine chart pointing out the plastic parts on airplanes clearly indicates the role of plastics in the Air Corps. Corsage boxes have given way to windshields of trainer planes, shower curtains t o cable coating, and radio cabinets to bomber d w r s and even entire plane bodies. The importance of plastics in warfare is clearly indicative of American ingenuity and scientific leadership. This section is well worth reading if only to find the tremendous part plastics is taking in defeating the Axis. A text on plastics wouldn't be complete without a discussion of synthctic rubber. In a brief manner, the authors present in Chapter 4, "Synthetic Fibers and Synthetic Rubbers," the progress in the synthesis of rubber, familiarizing the reader with the highlights of one of war industry's biggest projects. I t has been said, "When the minute man returns to his plow, it will have plastic handles!" The fifth and last chapter "Plastics and the Future," allows one's imagination to envision a dream home; I should say, a transparent dream home, with every modern convenience from a sewing machine that will "spot weld" elastics. to a transoarent chest full of nvlon shirts for men.. ~~~~~.

A SHORTER HISTORYOF SCIENCE. Sir W i l l i ~ mCecil Dampier (jormerly Whetham), Fellow and sometime Senior Tutor of Trinity College, Cambridge, Fellow of Winchester College. 189 pages. The Macmillan Company, New York, 1944. x 14 figs. 9 plates. 12.5 X 18.5 cm. $2.00. The purpose of this hook according to the author's preface is "firstly, to help the general reader, who wishes to know how science, which now affects his life so profoundly, reached its present predominance, and secondly, t o meet the needs of schools. Those older schoolboys whose chief subjects are scientific should look a t them also from a humanist standpoint, and realize their setting in other modes of thought, while those studying literature need some knowledge of science before they can he said t o he well educated." In spite of its inaccuracies and inadequacies the hook will fulfill these two purposes. It will give to the older schoolboys and to students of literature a taste of those interesting and tremendously important things of which a narrow specialization would be likely t o deprive them. I t s value will have been achieved if it is used as a first book in t h e subject, an introduction to more extensive reading by which gaps are filled in and misunderstandings are corrected. The book suffers from the necessity of being brief. I t fails t o mention many of the facts and factors which ought to be included in the barest outline of a history of chemistry. Conclusions are set down in too summary a fashion, and interpretations are couched in language which sometimes misleads. But t h e small hook is interesting t o read and contains many revelations for the student who has specialized narrowly either in literature or in science. TENNESL. DAVIS
