By a n interference method they found the thickness of the film to be 12.5 mm." The discussion of inflammation by Valy Menkin can well be applied to capillary permeability in shock. He compares the conflicting theories as t o the role of histamine and leukotaxine and pronounces in favor of the latter as the effective agent in increase of capillary permeability. He describes in detail his preparation of leukotaxine and its properties. In such great dilution as 1:10,000,000 i t shows an appreciable effect on capillary permeability. The molecular weight is about 5000. Beverly Clarke points out t h a t Goppelsroder began his work with spot tests (diffusion rings) as early as 1861. Clarke considers the more recent Tswett column work as a n extension of this diffusion ring study. The chapter by XfarInnes and 1.ongworth on Elccrrophorctic Study of Protein, is esperially rlpar a n d hrll,ful. Rheology is given theoretical treatment. Hickman records the development of his molecular still and its present uses. notably the concentration of fish liver oils for the vitamin A market. I t may seem that this volume stresses tools and methods of physics but colloid chemists need t o consider the possibilities of such tools in their own field. Alexander and his numerous associates deserve high praise for putting into a single large volume a small library of invaluable and stimulating information, Scientists in all fields will profit by reading it.

"the growing importance of formaldehyde as a commercial chemical, its many unique characteristics, and its varied applications have created a definite need for a systematic and critical account of formaldehyde chemistry." I t is the only current hook, in the English language, which is devoted exclusively t o the chemistry of formaldehyde. The chapter headings are: Formaldehyde Production (17 pages), Monomeric Formaldehyde (10). State of Dissolved Formaldehyde (11). Commercial Formaldehyde Solution (9).

THEFUTURE OF INDUSTRIAL RESEARCH. Frank A. Howard, Vice-President, Standard Oil- Company (N. J.), and President, Standard Oil Development Company; George W. Lewis, Director of Aeronautical Research, National Advisory Committee for Aeronautics; and Others. Standard Oil Development Company, New York. 1945. viii 173 pp. 15 X 23 cm. This is a collection of the papers given at the Forum in October, 1944, sponsored by the Standard Oil Development Company on t h e occasion of its silver anniversary. The general subject of the Fomm was "The future of industrial research." Three themes were used: (1) What should be the guiding principles and objectives for the commercial PCOgranIS of industrial research and development organizations? (2) How can small business serve itself and be served by industrial research and development? (3) What place should industrial research and development organizations allocate t o future work directed primarily toward national security? There are 13 papers presented by outstanding industrial research men, several of which were published in the News Edition of Indudrial and Engineering Chemistry. I n addition, there is the discussion by 22 others. The hook is attractively hound and printed, and isvery worth-while readingfor teachersand students of chemistry.

OUTLINEOP THE AWINO ACIDS AND PROTEINS. Edited by Meluille Sahyun, Vice-president and Director of Research, Frederick Steams and Company, Detroit, Michigan. Reinhold Publishing Corporation, New York, 1944. 251 pp. 16 tables. 8 figs. 15 X 23 cm. $4.00. According to the preface and the foreword the purpose of this book is to outline the essentials of thechemistry and the biochemistry of amino acids and proteins. There are 12 chapters and a n appendix by 13 well-qualified authors, three of whom were cantributors to Schmidt's compendium on amino acids and proteins. Six chapters (102 pages) are devoted to the discovery, isolation, synthesis, and analysis of amino acids and to the occurrence. properties, structure, analysis, hydrolysis, and amino acid content of proteins. Six chapters (84 pages) are concerned with the relation of amino acids to immunity and biologically important products, the role of amino acids in detouication, and the metabolism and nutritional value of amino acids and proteins. A list of 142 U. S. Patents on amino acids and related organic compounds is givenin the appendix. I t seems inevitable t h a t all collaborative works shall have shortcomings and the present boak is no exception. The following examples illustrate this point. The mechanism of protein hydrolysis, the racemization of optically active amina acids, the resolution of racemic amino acids, the nomenclature of natural amino acids, and other concepts employed in the text are inadequately explained. The accepted symbols for the natural amino acids are given on page 37, yet natural valine is designated on thispage as 1(+)- and on page 22 as d-. Duplication of information occurs throughout Chapters VIII t o X I I . Some key topics (such as transmethylation) discussed in the book do not appear in the subject index. There is no indication that foreign patents may be as important as those issued in this country. Some of the information in the tables on pages 67 and 131 is less reliable than that published in the 1944 literature. The introduction of photopaphs of 13 classical workers is a pleasing innovation but it could be inferred that Curtius, Drechsel, Ehrlich. Ellinger, Sorensen, and certain other individuals made less important contributions to the field of amino acids and proteins. I t might be assumed from the placement of their photographs that Fischer, Kossel, and Weyl were

authorities on amino acid metabolism. No hint is given concerning the origin, fundamental characteristics, or intended purDoses of the drawinas of amino acid crystals reproduced in Chaoter I . Important references t o the literature have been omittid particularly in Chapters 111, IV, and V. An essential amino acid is one required for nomal growth according to the definition on page 225. What is normal growth? Hegsted [ J . B i d . Chern., 156,247 (1944) I has defined an essential amino acid as one essential for life. Our views on this subject need clarification. Peptides, enzymes, physical properties of the amino acids, amino acid periodicity in proteins, structural models of protein molecules, microbiological assay of amino acids, and other topics have been neelected or have been treated too brieflv.

The more important materials are discussed in considerable detail as to: (a)industrial incidence, (b) physiological response and toxicity, (c) detectionand estimation. Theanalytical procedures are taken from the original sources without critical comment or suggested preferences. No information regarding antidotes or treatments is given. There are numerous references t o the literature. The final chapter (40 pp.) is devoted t o chemical i warfare agents. The appendix contains a number of useful tables in which are assembled data on limits of inflammability and explosive ranges, physiological responses, probable safe concentration limits of exposure to gases. The mechanical make-up of the book is attractive. This text is a good buy. RALPHE. OBSPER UNIVERSITY OX
