TRANSCRIPT

• By an 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 to 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 that Goppelsroder began his work with spot tests (diffusion rings) as early as 1861. Clarke con- siders the more recent Tswett column work as an extension of this diffusion ring study. The chapter by XfarInnes and 1.ongworth on Elccrrophorctic Study of Protein, is esperially rlpar and 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 to 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.

  FORMALDEHYDE. I. Frederic Walker, Chemical Research Divi- sion, Electrochemicals Department, E. I . du Pant de Nemours & Company, Inc., Niagara Falls, New York. Reinhold Pub- lishing Corporation, New York. 1945. xii + 398 pp. 28 figs. 31 tables. 15 X 23 cm. $5.50. Formaldehyde is Number 98 of the A. C. S. Monograph

  Series. According to the author. 'the growing importance of formaldehyde as a commercial chemical, its many unique char- acteristics, and its varied applications have created a definite need for a systematic and critical account of formaldehyde chem- istry.' I t is the only current hook, in the English language, which is devoted exclusively to the chemistry of formaldehyde.

  The chapter headings are: Formaldehyde Production (17 pages), Monomeric Formaldehyde (10). State of Dissolved For- maldehyde (11). Commercial Formaldehyde Solution (9). Physical Properties of Pure Aqueous Formaldehyde Solution (10). Hadu cccam dvbviewer. Distillation of Formaldehyde Solutions (6). Formaldehyde Polymers (38). Chemical Properties of Formaldehyde (15). Re- actions of Formaldehyde with Inorganic Agents (21). Reactions of Formaldehyde with Aliphatic Hydroxy Compounds and Mer- captans (12), Reactions of Formaldehyde with Aldehydes and Ketones (12), Reactions of Formaldehyde with Phenols (29), Re- actions of Formaldehyde with Carboxylic Acids, Acid Anhydrides, Acyl Chlorides, and Esters (8). Reactions of Formaldehyde with Amino and Amido Compounds (28). Reactions of Formaldehyde with Hydrocarbons and Hydrocarbon Derivatives (17). Detec- tion and Estimation of Small Ouantities of Formaldehvde (11). - . . . Quontitattvr An~lyi is of F~rmalddlydc Solutioni and Polynwrs (?I I , I lcxamethyler~ctctr~mi~~e 121; .

  One expects a book of this type to be comprehensive in its scope, hut a consideration of the discussion on the reaction of fonnaldehvde with the 'nitro-hvdrocarbons' leaves the reviewer with the impression that the suivey is lacking in its coverage of the field. This hook is, nevertheless, indispensable to any worker in the field and should be found on the shelves of every library.

  THE FUTURE OF INDUSTRIAL RESEARCH. Frank A. Howard, Vice-President, Standard Oil- Company (N. J.), and Presi- dent, Standard Oil Development Company; George W. Lewis, Director of Aeronautical Research, National Advisory Com- mittee for Aeronautics; and Others. Standard Oil Develop- ment Company, New York. 1945. viii + 173 pp. 15 X 23 cm. This is a collection of the papers given at the Forum in Octo-

  ber, 1944, sponsored by the Standard Oil Development Com- pany on the 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 prin- ciples 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 de- velopment? (3) What place should industrial research and de- velopment organizations allocate to future work directed pri- marily toward national security?

  There are 13 papers presented by outstanding industrial re- search 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. Further information concerning the availability of the book may he obtained by writing to: Standard Oil De- velopment Company, 30 Rockefeller Plaza, New York 20, New York.

  OUTLINE OP THE AWINO ACIDS AND PROTEINS. Edited by Meluille Sahyun, Vice-president and Director of Research, Frederick Steams and Company, Detroit, Michigan. Rein- hold 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 biochem- istry of amino acids and proteins. There are 12 chapters and an appendix by 13 well-qualified authors, three of whom were can- tributors 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 con- tent 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 metabo- lism and nutritional value of amino acids and proteins. Core java mcq questions with answers. A list of 142 U. S. Patents on amino acids and related organic compounds is givenin the appendix.

  I t seems inevitable that all collaborative works shall have shortcomings and the present boak is no exception. The follow- ing 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 con- cepts 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 Chap- ters VIII to XII . 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 photographs 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 place- ment of their photographs that Fischer, Kossel, and Weyl were
