ANALYTIC GEOMETRYAND CALCULUS,by Harold J. Gay, edited by Raymond K. Morley. 524 pages, diagrams, 15 >( 23 era. New York, McGraw-Hill Book Co., Inc., 1950. Price, $5.00. A first course textbook in analytic geometry and calculus which correlates both subjects in such a way that the applications of each to the other are considered. Plane analytic geometry and differential and integral calculus are considered in the first half of the book, and in the second half, solid analytic geometry and calculus are added as well as elementary differential equations. The treatment is in part by kinds of equations. Numerous illustrative examples and exercises have been included. ECONOMIC MINERAL DEPOSITS, by Alan M. Bateman. Second edition, 916 pages, illustrations, 16 >( 24 cm. New York, John Wiley & Sons, Inc., 1950. Price, $7.50. Designed primarily as a textbook, this work has found use as a source of information for all those interested in mineral deposits. The general scope of the first edition has been retained, although rather extensive changes have been made in Part I dealing with the principles and processes of the formation of mineral deposits. The lists of selected references have been considerably expanded. The broad scope of the volume with its detailed treatment of foreign deposits as well as American, contributes greatly to its practicality and usefulness. KENTS' MECHANICAL ENGINEERS' HANDBOOK, in two volumes. POWER VOLUME, edited by J. Kenneth Salisbury; DESIGN AND PRODUCTION VOLUME, edited by Colin Carmichael. Twelfth edition, illustrations, 15 X 22 cm. New York, John Wiley & Sons, Inc., 1950. Price, $8.50 each volume. Any work which has been published as long (fifty-five years) as Kents' handbook needs little introduction to its potential users. This note, then, need record only the fact that a new edition has appeared and point out the major changes that have been made. Each volume has undergone considerable rearrangement of the order of sections, with both additions and deletions. In the volume on power, .considerable emphasis has been placed on the new developments such as atomic power, co mbustion gas turbines, supersonics, jet propulsion, heat pumps, panel heating and others. The volume on design bears a new subtitle Design and Production in place of the previous Design, Shop Practice, giving recognition to "the fact that design and production are becoming recognized as simply two phases of a single activity--the engineering of a product from the inception of an idea to the completion of the finished article at an economical cost." Both volumes show a large increase in the number of pages, and both have detailed indexes. Based on the contributions of a large number of authorities, Kents' in the new edition will continue to merit the esteem in which it is held. SEMI-CONDUCTEURS ]~LECTRONIQUESET COMPLEXES D~RIV]~, THI~ORIES--APPLICATIONS,by Stanislas Teszner. 96 pages, illustrations, 21 >( 30 cm. Paris, Gauthier-Villars, 1950. Price, 1200 fr. In this work on electronic semi-conductors, the author treats, in the first part, of the various phenomena of these substances and .discusses the theories which have been advanced to explain them. In the second part he considers the practical applications of the seml-conductors, such as rectifiers, detectors and thermistors. With a lengthy bibliography, this should prove a useful summary of both the scientific and technical information on a subject of increasing importance in electricity and radio. STRENGTH OF MATERIALS, by James E. Boyd. Fifth edition, revised by Samuel B. Folk. 417 pages, illustrations, diagrams, 15 >( 24 cm. New York, McGraw-Hill Book Co., Inc., 1950. Price, $4.25. A standard textbook on a basic phase of engineering now appears in a fifth edition in which the editor has made a conscious attempt to emphasize the fundamentals of the theory. Various changes have been made in the order of topics; Mohr's circle for the solution of simple stresses has been introduced early to give the student familiarity with its use, and new material has been included. Problems have been added to bring the total to over a thousand.
