THE SCIENTIFIC MONTHLY-ADVERTISEMENTS i

XI 7~~~~~~~~~~~~~~~~~~~~ RE,CENT WILEY BOOKS ELEMENTS OF QUANTUM MECHANICS

By SAUL DUSHMAN, PH.D., Assistant Director of the Besearch Laboratory, General Electric Company

The basis for this book was a series of articles by the author which appeared in the J'ournal of Chemical Education. It affords an introduction to the inathematical technique and physical interpretatio:n of quantum mechanics. The object of the book is to explain as fully as possible the steps involved in the solution of any problem, so that the reader is gradually introduced to the miathematies as a "tool."

452 pages; 82 illus.; 6 by 9; $5.00

ECOLOGICAL ANIMAL GEOGRAPHY From the " Tiergeographie auf oekologischer Grundlage" by RICHARD HESSE, Professor of Zoology, University of Berlin; translated and revised by W. C. ALLEE, Professor of Zoology, University of Chicago, and KARL P. SCHMIDT, Field Museum of Natural History, Chicago

Summarizes the existing knowledge of animal ecology in a comprehensive manner. The terminol- ogy and reference material have been adapted to English-speaking studeiits and obsolete matter has been eliminated. The work presents in one volume a synthesis of the facts of animal distri- bution as they depend upon various environmental faetors; it is the only book of comparably extended treatment in print in English which deals specifically with animal distribution.

597 pages; 135 illus.; 6 by 9; $6.00

CROP MANAGEMENT AND SOIL CONSERVATION (Wiley Farm Series, A. K. Getman and C. E. Ladd, Editors)

By JOSEPH F. Cox, Senior Agronomist in the Division of Pro- gram Planning, U. S. Departtment of Agriculture, and LYMAN E. JACKSON, Junior Dean, College of Agriculture, Ohio State Uni- versity

It is the primary object of this new book, in dealing with specific crops, to present in a simple way the major operations that will enable the grower to raise and market his crops successfully. Practices that are effective ill reducing the cost of production, improving crop qualities, maintain- ing fertility, and marketing effectively are given particular emphasis. The solid and lasting achievements of recent years in developing a national program directed toward the balancing of crop production. and the conservation of soils are given an important place.

610 pages; 199 illus.; 51 by 8a; $2.75

TEXTBOOK OF THERMODYNAMICS By PAUL S. EPSTEIN, Professor of Theoretical Physics, Cali- fornia Instititte of Technology

There are practically no books on thermodynamics which have been written in America by physi- cists, and probably none in England, of a scope comparable with this book. It constitutes a very successful attempt to combine the points of view of both chemists and physicists. The book should therefore be useful to workers in both fields. The style is clear; the presentation is well thought out and logical. The book applies the thermodynamic methods to many specific types of problems, as well as developing general formulas.
