amount of material to which this statement does not apply. We believe the reviewer has lost the point of view from which the bulletin was prepared-namely, the purpose and intent to place under one cover information and data on this subject that might be of use t o the general public, particularly t o the users of powerplant equipment. We feel that if we should take the stand that no material except that which includes only new facts should be published there would be a material reduction in the technical literature. We are not sure but that such a step would he desirable, though, beyond question, it would materially handicap many engineers and scientists who wish to familiarize themselves with various fields beyond those in which they maintain acute interests. We do feel, however, that the book has added new facts. It has advanced a theory explaining stability of metals at elevated temperatures; it has developed the mathematical relationship between stress, temperature, deformation, and time; and it has given data on a considerable number of new alloys

Ignition Temperature of Carbon BisulfideCorrection Editor of Industrial and Engineering Chemistry: It has been brought to my attention that the work of Masson and Hamilton [IND. ENG CHEM., 19, 1335 (1927)J was incorrectly quoted in my paper entitled “Auto-Ignition Temperatures of Flammable Liquids,” Ibid., 21, 134 (1929). The value of 343 O C. quoted as the ignition temperature of carbon bisulfide is acknowledged t o be an error. FACTORY MUTUALLABORATORIES N. J. THOMPSON BOSTON, MASS. April 1, 1929

BOOK REVIEWS International Critical Tables of Numerical Data, Physics, ChemW. WASHBURN, istry and Technology-Volume V. EDWARD Editor-in-Chief. Prepared under the auspices of the International Research Council and the National Academy of Science by the National Research Council of the United States of America. ix 4- 470 pages. McGraw-Hill Book Co., Inc., New York, 1929. To be published in 7 volumes. Price, $84 per set on orders per set only; payable a t the rate of $12 per volume as issued. Volume V of International Critical Tables treats the following subjects: viscosity and fluidity; kinetics of physical processes ; mechanical equivalent of heat; specific heat; thermal effects accompanying physical and chemical processes; thermal conductivity; radiometry; spectroscopy; photometry; mechanical equivalent of light; photography; and properties of soaps and their aqueous solutions. An index for Volumes I to V is included. The completeness of the data is somewhat variable; thus, the viscosity data include only a few pure liquids (the remainder to appear in a later volume), but the data on viscosity of solutions, aqueous and non-aqueous, seem quite complete. The thermal data seem to be the most important part of this volume, and appear to be quite up to date, as the reviewer found data published as late as 1929! The full bibliography of absorption spectra of solutions will also be welcomed. A number of short chapters on highly specialized subjects, such as “electrically exploded wires,” “pole effect,” “emission of light by spark discharges in liquids,” contain data not usually included in books of tables, and which will be useful only t o the specialist. Naturally, International Critical Tables becomes increasingly valuable as each new volume appears, and a final index will certainly double the usefulness of the series to the average consultant, since the system of arrangement of data is not always simple t o the uninitiated.-GruHAM EDGAR

This book fills a definite place in the literature of rapid and micro methods. It is in the latter field that so much has been accomplished with so little material. The use of such methods has resulted in important contributions to our knowledge, especially of biological processes; nevertheless one stands in awe of the possibilities of error in manipulation. The value of this book is enhanced by the particular appreciation of the possibilities of technical error.-PAuL E. HOWE Heat Transmission. BY MARGARET FISHENDBN AND A. F. DUFTON. Department of Scientific and Industrial Research, Building Research, Special Report 11. H. M. Stationery Office, London. Price, 9 d. net. The report is a well-presented resume of the present status of our knowledge of the basic factors influencing the rate of heat transmission through walls. A limited amount of data gathered from various sources dealing with thermal resistance of various walls, heat transfer between surfaces, and effect of meteorological conditions on these surface coefficients is presented. The general principles developed are applied to a discussion of heat losses from buildings under natural weather conditions. Further experimental work is being done to gain more systematic information on the effect of meteorological conditions on the rate of heat losses from hui1dings.-E. C.
