I t is larger by a third, despite the elimination of an entire chapter on Production and Consumption occasioned in part by the inzdequacy of recent world-wide statistical data. A greatly expanded and correspondingly mare useful table of contents is now provided, and further improvement has been effected in s. number of places by rearrangement of subject matter into more logical order within the chapters. The hundreds of literature references are carried as footnotes to the text and numbered serially within each chapter. Both author and subject indexes are provided. The book is of pleasing design and sturdy construction, conforming in all its physical features to the high standard set by the publishers far the series of monographs on Fsts and Oils of which this volume is one.

The remainder of the book is devoted to method8 of isotopic analysis of heavy water. Save far background material, this consists almost entirely of reports of original work. Experimental and computational procedures are presented in considerable detail. Nearly one half of the hook is devoted to irrotopie analyses by the mass spectrometer. In view of the current commercial availability of mam spectrometers, the considerable space devoted to construetionsl details of the mass spectrometers whioh were employed will probably be of little interest to those primarily interested in isotopic analyses. However, the procedurespreparation of samples, computations, edibrations, ete.-will still be of value.

FOR this beginning book in quantum mechanics, the author pruwpposes a knowledge of elementary mathematical physics, including mch things as vector analysis and electromagnetic theory. After a brief historical introduction he pmceeds, in the third chapter, to develop Schr6dinger's equations, including the effect of an eleetromttgnetic field. The problems that mu be solved exactly are then taken up. Perturbation theory and the variation method ttre followed by spin theory, one electron spectra, and two electron spectra. Collision problems then precede the electron theory of solids. The book ends with applications to electromagnetic theory. The book is well written and will he enjoyed by those who have the preparation which a. good graduate student in physics should have. Chemists will not find even the hydrogen molecule treated, but will find the book a valuable treatment of the fundamentals with many interesting physical examples.

THIS volume is one of the National Nuclear Energy Series (Manhattan Project Technical Section). Most of the volume is occupiel by description of original research which was performed during the war and which has now been declassified. The first chapter presents best values of an extensive list of physical properties of heavy water. Theseare based upon a critical survey of the literature supplemented by further experiments in cases where previous work appeared inconsistent or inaccurate. The second chapter presents values of equilibrium constants for hydrogen-isotope exchange reactions between hydrogen and water, hydrogen and ammonia, and oxygen-isotope exchange between carbon dioxide and water. The constants are computed by statistical mechanics from spectrosoapic data and checked experimentally. The last chapter deals with the natuml abundance of hydrogen and oxygen isotopes. Previous literature is critically surveyed and further experimental work is presented.

THIS volume eummsrizes the theoretical work of tbe SAM Laboratories during the period from 1940 to 1945 relating to the centrifugal, electromagnetic, electrolytic, chemical exhmge, thermal diffusion, and distillation methods of separating isotopes. In the first five chapters, the theory of cascades is developed in as general a way as possible to permit extension to other types of separation prohlems. A discussion of application has been somewhat hamoered bv existine securitv restrictions. The book is entirely m'athematical a n d i n a te&nology that is strange to chemists. The obvious importance of the subject, however, makes it mandatory on departments of chemical engineering to become familiar with the theories of separations, and t o extend them to new developments. This book will be of aid in making this extension. LAURENCE S. FOSTER B s ~ ~ o m M ~, s s A o n n s e ~ ~ s
