RETARDATION OF EVAPORATION BY MONOLAYERS: TRANSPORT PROCESSES, edited by

Unbelievable as it seems, this volume contains the proceedings of a symposium held in April, 1962, and its publication date was the same month. If all proceedings of symposia could be made available to the public this quickly, there would be more market for-them. Twemy three authorities have contributed papers to the volume. After two introductory chapters covering the evolution, purposes and procedures of taxonomy, the papers fall into two major categories--current approaches and synthesis--with a concluding chapter entitled "The Microbial Species--a Macromyth?" In the first category, five contributions cover the taxonomy of protozoa, algae, microfungi, bacteria and viruses, grouped under the sub-head "Morphological," five papers (under non-morphological) deal with biochemical aspects, antigens, and pathogenicity of fungi, and one paper covers genetical aspects of microbial classification. The six papers in the second category deal with the construction of taxonomic groups, the systematics of actinomycetes, the phylogenetic concept, virus classification, nomenclature and identification. Each contribution is self-contained. The volume as a whole reflects facts and uncertainties of present-day microbial classification, both theoretical and practical, in a way which does credit to the authors and editors.

Nineteen papers consider the properties of various monolayers, the physical processes involved in evaporation and retardation, and the interrelationship between these processes and monolayers. Originally presented at a September 1960 symposium, the papers reflect the state of the art at that time.

ULTRA-VIOLET AND INFRA-RED ENGINEERING,

by W. Summer. 300 pages, diagrams, plates, 5½ x 8½ in. New York, John Wiley & Sons, Inc., 1962. Price, $7.50. In developing the engineering aspects of uhra-violet and infra-red radiation, the author first devotes 92 pages to a theoretical introduction covering sources, filters, harmonization, detectors, etc. His next section deals with equipment, including generators, heat transfer, control gears and phosphors. Under "Engineering Applications," thirty six sections cover individual applications, for example, photocopying processes, infra-red heating, carpet drying, health lamps. A short fourth part deals with the health hazards involved and suggests protective measures.

REGULAR SOLUTIONS, by Joel

H. Hildebrand and Robert L. Scott. 180 pages, diagrams, 6 x 9 in. Englewood Cliffs, Prentice-Hall, Inc., 1962. Price, $7.00.

This book brings together all the quantitative aspects of regular solutions and defines the present status of the theory. Omitting topics treated in detail elsewhere (such as hydrogen bonding, high polymers), the authors cover, for example, thermod~,namic relations, entropy of mixing, intermolecular forces, liquid-liquid mixtures. CODING THEOREMS OF INFORMATION THEORY,

byJ. Wolfowitz. 125 pages, 6 x 9 in. Englewood Cliffs, Prentice-Hall, Inc., 1962. Price: $9.35 (trade); $7.00 (text). The purpose of this monograph (first given as a lecture course on information theory at Cornell in 1958-59) is to provide an easy introduction to the ideas and principal theorems of coding theory. It is written for mature mathematicians, but it presupposes no prior knowledge of information theory. Some of the topics discussed are the discrete memoryless channel, compound channels, the discrete finite-memory channel, discrete channels with a past history, general discrete channels, the semi-continuous memoryless channel, continuous channels with additive Gaussian noise, and mathematical miscellanea.

Main emphasis is on physical principles; an undergraduate knowledge of calculus is sufficient for the mathematics involved. One of the special features is the chapter on helium in rotation.

F. W. Hutchinson, with thermal tables and numerical examples by M. O. Cotter. 494 pages, diagrams, 6 x 9 in. New York, The Ronald Press Company, 1962. Price, $12.50.

This text for advanced undergraduates and graduate students combines the atomistic and classical thermodynamic approaches. Thus, the author hopes to bridge the gap between the physicist's and the chemist's approaches to the subject. The first part of the book covers basic thermodynamic concepts (the three laws, entropy, etc.); in the latter part, defects are treated. The book covers all important classes of crystals and solids including metals, semiconductors (elemental and compound), and insulators. Both atomic and electronic defects in crystalline solids are treated. AGGLOMERATION~edited by William A. Knepper.

1109 pages, diagrams, illustrations, 6 x 9 in.

This book is concerned primarily with the problems of accurately determining the design load necessary for maintaining a selected temperature and humidity within a structure. Four main divisions of the book cover: (1) definition of a system (physiological, psychological and climatological influences); (2) the effectiveness of the thermal barrier represented by the structure (including basic equations for mass transfer and application of the steady-state heat-transfer relationships); (3) special design problems (panel heating, solar heating, etc.); and (4) methods for investigating transmission load under transient or periodic conditions. Extensive thermal tables are included.

Price, $25.00. This volume contains the thirty-six papers presented at an international symposium held in April 1961, together with the prepared-inadvance discussions and on-the-floor discussions which the papers evoked. Contributors from nine countries cover many phases of sintering, pelletizing, nodulizing, briquetting, powder metallurgy, etc., for ferrous, non-ferrous, metallic and non-metallic materials. Abstracts for each paper are printed in English, French and German, but the papers themselves (and the discussions) are in English. This is the most comprehensive work to appear on the subject.

SHIp HULL VIBRATION, by F. H. Todd. 364 pages, diagrams, 5] x 9 in. New York, St. Martin's Press, 1962. Price, $22.50. The author brings together in one volume the scattered data on ship hull vibration, in a practical book written with the needs of the naval architect and shipbuilder in mind. After describing the types of vibration and their causes, the author presents the mathematical bases needed for the solution of vibration problems. Methods of prevention and cure are set forth, and the use of computers in the solution of vibration problems is discussed. MODULATION AND CODING IN
