electricity was discovered, nor when a loadstone was used for the first time in navigation, and we may wonder whether they were new a t the time of Prometheus. And so it goes throughout the "Introdue tion" which culminates in a. call for ". . . one great effort for more effective utilization of man's recorded knowledge. . . This is a worthy cause but perhaps we should first acquire the knowledge. Upon boarding the galactic conveyance and before admission t o the company of the select we are to pass through a purgatory where we are to be cleansed of such archaic impediments as grammar, syntax, etymology, etc., and then iustmeted in "language engineering." This new form in which the wise will commune is defined on p. 330 in "phrastie elements" whioh I do not understand. Whatever i t does, the article is certainly phrssy. If we still persist in using that obsolete tool there ia no hope for us. Page 93 warns us to "keep in mind that the basic struetural features of modern language were developed long before the dawn of our modern industrial era." Do we not realize that dealing with our grocer or butcher, or when ordering a double bourbon in our favored bar, we are doing so in the language of Beowulf? Such othera, as Mendeleev, Planek, or Einstein did formulate their ideas in the existing languages hut for "documentation" these me inadequate. On page 197 we find, "The lihrmian of the future. must he a creature of many muts, tions. . ." What does this mean? There are more questions of this kind that we could ask if space permitted. However, the hook contain8 several papers of value and interest, such as those by Adkinson, Fano, and Bernier, hut these presentations are too "earthy" and of little use in the stellar realm of manage ment, executives, decision makers, and other Olympians. The problems of gathering, recording, storing, and dissemination of scientific information are very important and need solution. The problems are not new; they existed a t the time of Hammurahi and they will exist after wire recording will become archaic. Kent (pp. 2741) outlines the problems clearly and presents the cause for s cooperative effort very effectively. We ehould work for the best possible solution of these problems. But whatever these may he, I do not believe that they will stem from "language or engineering," "conceptualization," "semantic factoring."

THEmajor portion of this volume, eonsisting of eight chapters, constitutes a eoncise introduction to the pertinent nn-
clear engineering arising in reactor design and operation. The opening chapter gives the necessary nuelear physical background and is followed by two chapters, totaling 91 pages, whioh develop reactor criticality conditions and hoth steady state tend transient neutron distributions. Chapter Four covers radiation shielding, Chapter Five, reaotar materials. Only the three final chapters, totaling 65 pages, are primarily related to the question of power production, and here are covered thermal stress, power extraction, and thermal power cycles. This hook is recommended to the reader with a background in differential equations who desires familiarity with quantitative considerations of thc neutron reaetor. R. A.

PHYSICAL TECHNIQUES IN BIOLOGICAL RESEARCH. VOLUME 2: PHYSICAL CHEMICAL TECHNIQUES Edited by Gerald Oster, Polytechnic Institute of Brmklyn, and Arthur W. Pollister, Columbia University. Academic Press Inc., New York, 1956. xv 502 pp. 15.5 X 23.5 cm. $12.80.

BIOLOGICAL research is distinguished by the complexity both of the systems investigated and the methods employed. Few biological scientists tare familiar with all the techniques that could he used to advantage in their work. On the other hand, methods are sometimes developed and refined by scientists who are unaware of specific systems for their novel applioation. Unfortunately, a scientific method is generally reviewed in detail far the expert active in the field or outlined superfieidly in a. brief qualitative descrip tion. Neither approach satisfies the real need of the research worker. In the present volume, the editors and authors are to he complimented for maintaining a balanced diseu~sion that indicates the limitations and advantages of many physical chemieal techniques. This hook, the second in a three-volume series edited hy Gerald Oster and Arthur W. Pollister, reviews physical chemical methods commonly used by biochemists, cytochemists, and biophysicists. The nine chapters include: Tracer Techniques: Stable and Radioaetive Isotopes (Jacob Saeks); The Measurement and Properties of Ionizing Radiation (J. S. Kirh,vSmith); Sedimentation, Diffusion, and Viscosity (A. G. Ogston); Surface Film Techniques (Alexandre Rothen); Adsorption and Chromatography (Norman Applesweig and Thomas F. Cleary); Electrophoresis and Ionophoresis (Kurt G. Stern): Electrical Potential Differenees (K. S. Spiegler and M. R. J. Wyllie); Magnetic Methods (Scott Rlois); and X-Ray Diffraction and Scattering (Gerald Oster). The value of m y measurement is limited by the modifications in the experimental system that result from the measuring process, and the assumptions necessaF for the interpretation of the
