A feature of the book is the criticism of the naive psychology of Jeans, Eddington and Einstein in their more mystical speculations regarding the structure and control of the universe. The book is one of a series known as the Contemporary Library of Psychology which has been drawn up with a view to presenting a comprehensive and accurate perspective of contemporary psychology in a popular way without losing scientific accuracy. Its treatment is simple, clear cut, It is a book for serious general readers. Workers in all sciences whose frontiers are consistent, mature and emphatic. bounded by psychological

This is a revised and corrected second edition of the English-French technical dictionary, by Guy Malgorn. The vocabulary applies principally to various types of machine tools, the elements of the internal combustion engine, aviation, electricity, radio broadcasting and communication, naval construction, metallurgy and so forth. The front of the volume contains a number of conversion tables often of great convenience to technical men. T. K. CLEVELAND. ELECTROCHEMISTRY,PRINCIPLES AND PRACTICE, by C. J. Brockman, Associate Professor of Chemistry, University of Georgia. 348 pages, tables, 15 X 23 ems. New York, D. Van Nostrand Company, Inc. Price $4.00. This work represents a very worthy addition to the series of Industrial Chemical Monographs. Electrochemistry may not be still in its infancy but neither has it yet attained the stage of its fullest development. The author has undertaken to present his subject in a not too technical manner. As such, this book will appeal not only to the chemist but to the plant manager, manufacturer and executive as well. All types of chemical processes involving the use of electricity are described entertainingly and the extensive treatment of the subject makes the book a valuable addition to any chemical or general technical library. The author begins with a chapter on the Principles of Electrochemistry. This is logically followed by a description of oxidation reactions at the anode and reduction reactions at the cathode. The electrometallurgy of metals comprises a large section of the book and well it might, for such processes of metal winning and refining furnish the basis for many large modern plants. A study of the manufacture of bleaching agents is essentially a course in electrochemistry. The present-day low prices for such metals as aluminum, magnesium, sodium, calcium, cerium, and beryllium owe their existence to improved electrochemical technique. In many instances it is not the conductivity of substances that is
