BOOKREVIEWS

The jacket points out t h a t “the material contained in this book is, for the most part, the result of a series of lectures given under the Engineering Extension Program of the University of California in Berkeley during the summers of 1956 and 1957. This course, entitled ‘A Survey of Nuclear Engineering for Management,’ consisted of lectures presented by apprqyimately twenty guest speakers-all specialists in the field. A t least several of the eighteen chapters have been updated to about 1959. The presentation is directed toward the industrialist who has a n engineering degree but has not been actively engaged in engineering for five to ten years. Accordingly, the general level of presentation is relatively unsophisticated. This should not detract from its value to most non-experts in nuclear reactors. The book is divided into four parts, plus a n introductory history of atomic energy by Edward Teller. Part I , Nurlear Energy-Basics and Part 11, ?;ucleav Energy-Applications, are about one hundred pages each. Part 111, Nucleay Energy-Safety, which includes a chapter on medical aspects of radiation, and Part I V , iyuclear Energy-the Future, are each about fifty pages in length. More than half of Part 11- is devoted to a chapter on controlled-fusion power. Parts I and I1 include chapters on fundamental principles of nuclear reactors, breeder and converter reactors, the production and processing of nuclear materials, economics of nuclear power, research reactors, sodium-graphite and organic-moderated reactors, and industrial uses of isotopes. There is a chapter dealing specifically with the Shippingport Atomic Power Station. As a result of the multiplicity of authors there is some non-uniformity in presentation and some overlapping in coverage as well as areas of non-coverage. However, these are only minor drawbacks in a generally valuable book. CHEMISTRY DIVISION .%RGONNE KATIOXAL LABORATORY W. M. MASNING 9i00 S. CASSAVENUE ARGONNE, ILLISOIS

The following chapters describe for the most part semiquantitative observations on enzymes of questionable homogeneity and poor characterization: “Invertase,” “Cathezsins,” “Glutaminase,” “Plasmin,” “Other Glucosidases, “0-Glucuronidase,” “Hyaluronidases,” “Xeuraminidases,” “Fatty Acid Esterases of Low Eserine Sensitivity and Related Enzymes,” “Butyryl- and Propinylcholinesterases and Related Types of Eserine-Sensitive Esterases” and “Phospholipases.” The book is valuable in directing attention t o rich areas of research of varying complexity, suitable for both the physical scientist and the biologist. Volume IV of “The Enzymes” belongs in every biochemistry and chemistry library. It is recommended to all enzymologists, to thosc interested in the special topics covered, and to all students of molecular biology. DEPARTMENT OF BIOCHEMISTRY CORXELLUNIVERSITY GEORGE P.
