JOURNAL OF CHEMICAL EDUCATION ment department of the du Pont Company, whose book on Chemical Engineering Economics has been used widely since 1926. Dimensional Analysis (9 pages), a subject of importance to chemical engineers, was prepared by D. Q. Kern, director of the process engineering division, Patterson Foundry and Machine Company. Electroplating (36 pages) was discussed by C. L. Faust, Battelle Memorial Institute, who is the new president of the Electrochemical Society. Electrostatic Precipitation (17 pages) was prepared by L. M. Roberts, assistant technical director of the Research Corporation. Organic Electroayntbesis (6 pages) is the special field of Sherlock Swam, Jr., of the University of Illinois, whose papers in this field are well known. Electrochemistry (55 pages), as the physical chemist prefers it, was the speciality of G. C. Akedof, formerly of Yale University and now of Mellon Institute. Electronics (51 pages) is the everyday field of G. A. Morton and M. L. Sehultz of the R.C.A. Laboratories. Dielectrics (25 pages) was prepared by E. B. Baker and W. C. Gogginof the plasticsdivisionaf the Dcw Chemical Company. Of interest to every organic chemist will he the chapter on Eatcrification (42 pages) by C. E. Leyes, head of the development and research department of the plastics division of the Celanese Corporation of America. Organic esters (27 pages) are discussed by T. E. Jordan, now a research supervisor for the Barrett Division of Allied Chemical and Dye Corporation. A goup discumion of Ethers (18 pages) h d s Mary Magill, of Chemical Abstracts, coopersting with J. G. Park and C. M. Beamer of the Enjay'Company, Inc. The preparation of that basic organic raw material, Ethylene (18 pages), is discussed by John Happel, previously of Socony-Vacuum Oil Company and now professor of chemical engineering a t New York University. Ethylene Amines, by John Conway, of Carbide and Carbon Chemicals Division, and Ethylene Oxide by R. S. Aries and H. Schneider, consultants, and K. Gerzon of Eli Lilly and Co., are products of the ethylene group. The lengthy section on Dyes, intermediates, application, and evaluation (119 pages) is the combined effort of eleven workers mainly from General Aniline and Film Corporation's General Aniline Works Division and General Dyestuff Corporation. One exception is Calco Chemical Division's August Mere, a man whose long experience in the dyestuff industry eminently qualifies him to write on the history of the industrv. A name not to be overlooked bv orertnic chemists is Oliver &mm, of Parke, Davis, and company, wio prepared the section on Eoineohrine. ~i&hekistswill be partioulerly interested in the sections on Enzymes (28 pages) by A. K. Balls, of the U. 6. Bureau of Agricultural and Industrial Chemistry, and on Eggs (13 pages) by A. L. Romanoff, of Cornell University. The Theory of Explosions and Gaseous Explosions are discussed by G. B. Kistiakowsky, professor of physical chemistry a t Harvard University and H. F. Coward, one time of the U. 8. Bureau of Mines and now of the British Safety in Mines Research Board. The reviewer again wiehes to stress the importance of all sections and all authors and express the regret that space limitations prevent mention of all. Certainly all have contributed handsomely to making a worth-while volume and set of E.C.T. KENNETH A. KOBE

THIS book provides an excellent survey of atomic physics. The author is concerned with ideas rather than with experimental or mathematical techniques. Equations are wed, and the proofs, sketched, as they are needed to develop the ideas. Experiments are likewise given in outline. The book, after a brief introductory chapter, review subjects like Dalton's laws much as is done in a good course in general chemistry, but this doesn't prevent the author from discussing the relativity correction to electron mass as it is needed. All theories and experiments which illuminate our ideas on atoms, ions, electrons, nuclei, and protons are drawn on in this chapter. In the very readable 124 pages devoted to spectroscopy, there is much use of vector addition. The outlook here is not unlike that in Sornmep feld's classical book. Quantum mechanics is developed briefly with considerable attention to the uncertainty principle, Fermi statistics, and the general philosophical implications. Nuclear physics gets crowded into 100 pages. The intimate connection between nuclear reactions, the heat of stars, and the birth of the universe are duly examined. Next, we have a treatment of molecules--largely diatomicand a final chapter on solids. These are good introductions to the fields treated. "Atomic Physics" deserves to be read widely by those seeking an overview of this fascinating field. HENRY EYRING

MANUAL OF 5TANDARDlZED PROCEDURES FOR SPECTROPHOTOMETRIC CHEMISTRY
Harold I. Fister, Director, Viola Mae Fister Memorial Reaearch Laboratory. Standard Scientific Supply Corporation, New York, 1950. 728 pp. Illustrated. 26.5 X 29.5 cm. Tms is a voluminous, practical laboratory manual containing detailed directions for carrying out some 200 clinical analytid methods, on urine, blood, feces, etc. It is intended to be a suitable set of instructions to laboratory workers with limited experience in spectrophotometry. Printed clearly, on heavy paper, and bound in a heavy loose-leaf binder, it is well designed for use on the laboratory desk. The author lay8 great emphasis upon use of calibrated glassware, careful preparation and preservation of reagents, and strict adherence to the details of techniques. He gives assurance that when all this is done othera will he able to duplicate his own results with these methods. He gives calibration curves for practically every method, prepared with standards in the Colemn Universal Spectrophotameter. Although it is intended that these shall be used by others only as guides, nevertheless the author is confident thet if proper precautions are observed they will serve within the limits of routine clinical work. Thia manual will certainly he valuable to any clinical labomtory. NORRIS W. RAKESTRAW S o s r p ~ sI ~ a ~ ~ r m OF r oO n em~oosa~ar La Jozr,~,C ~ l ; r r o a w ~ ~
