ELECTRONIC STRUCTURE AND CHEMICAL BINDING, WITH SPECIAL REFERENCE TO INORGANIC CHEMISTRY, by Oscar Knefler Rice. First Edition, 511 pages, New York, McGraw-Hill Book Company, illustrations, tables, 16 X 24cms. Inc., 1940. Price $5.00. Although this book was the outgrowth of a course of lectures entitled “Adgiven by the author at Harvard, it bears little vanced Inorganic Chemistry,” resemblance to the usual text on Inorganic Chemistry. The book, in the words of the author, “. . . has become essentially a discussion of the chemical bond as exemplified in inorganic compounds.” The object of the first part of the book is to give the reader an insight into This is done by means of an abridged the properties of electrons and atoms. quantum mechanical treatment, in which the author gives the ideas lying behind the theories, rather than all the mathematical detail. This discussion moves logically into the consideration of theories of valence, and then various types of chemical bonds. A large portion of the book is devoted to study of types of binding in crystals. The last chapter considers water, hydrates, and aqueous solutions. Although the emphasis in the book is largely on the side of inorganic chemistry, it is nevertheless required reading for the organic chemist. The book is well written and well printed, and represents a good job very well done. G. S. GARDP~RR PRINCIPLES OF ELECTRICAL ENGINEERING SERIES. ELECTRIC CIRCUITS, A FIRST COURSE IN CIRCUIT ANALYSIS FOR ELECTRICAL ENGINEERS, by Members of the Staff of the Department of Electrical Engineering, Massachusetts 782 pages, illustrations, 16 X 24 ems. New York, Institute of Technology. Price $7.50. John Wiley & Sons, Inc. Evidences of technological development in electrical engineering are plainly seen everywhere. Acceleration of applications is also very apparent. There is Yet, seldom any question raised beyond the mere acceptance of these facts. aside from the basic reason-the urge to greater accomplishment-human mechanics angle must of necessity be considered as a very large contribution to More men with advanced knowledge are enincreasingly rapid development. gaged in the work, there is more efficient coordination of activities and thought, and most important of all there has been a constant and progressive evolution in Without these, it is doubtful the methods of imparting knowledge to the workers. that progress could have been made on such a broad front. This book is an illustration of progress sought and accomplished in teaching Dr. Karl T. Compton methods at the Massachusetts Institute of Technology. states, in the foreword, that the Department of Electrical Engineering has for some years been engaged in an extensive program of revising as a unit substantially its entire presentation of the basic technological principles of electrical engineering. 673
