second edition the author admits that the field has grown so greatly that it is difficult to present an adequate review and discussion of it. If one wishes to obtain a general picture of the present state of petroleum chemistry or the industrial processes for the manufacture of various products from petroleum and natural gas, then this book should be very useful. There are numerous references to the literature, including the patent literature. Some parts of the book are not as up-to-date as others, for example, the chapter on oxidation of paraffins. In addition, this reviewer fiinds an occasional misquotation of the literature, for example, in referring to a paper of Walsh on page 152, the incorrect statement is made that cool flames appear in the oxidation of methane. One cannot find detailed critical discussions of the mechanisms of the thermal decomposition nor of the oxidation of paraffin hydrocarbons nor of the action of catalysts in this book, but one can find information as to the types of processes used in the utilization of petroleum. In general the book is a review of the chemistry of the nonbenzenoid hydrocarbons with the emphasis on industrial processes and as such has a definite place on the reference shelf of anyone working in the petroleum field. There are good subject and author indices which aid one in referring to the original literature. WILLIAM E. SCOTT PUBLIC HEALTH ENGINEERING, by Earle B. Phelps and others. Volume 2,213 pages, illustrations, 14 X 22 cm. New York, John Wiley & Sons, Inc., 1950. Price, $4.00. This second volume devoted to public health deals ostensibly with food and the principles of sanitation in food production, handling, and distribution. Actually the text material is not at all so general. Of the eight highly descriptive chapters, four are given over to the subject of milk production, pasteurization, milk plant processes and equipment, and plant inspection and control; one to shellfish and their live storage facilities; one to public eating and drinking places; and one to garbage disposal from the point of view of rodent control, and one to food control administration. To this reviewer, the book seems shallow and void of statements of basic principles of public health sanitation as applied to food. It is felt that fully one half of the material could have been omitted with no loss. On the other hand, perhaps a more appropriate title indicative of the emphasis placed on milk would be more satisfactory. S. CHARP
BOOK NOTES INDUSTRIALSOLVENTS, by Ibert Mellon. Second edition, 758 pages, diagrams, 16 X 24 cm. New York, Reinhold Publishing Corp., 1951. Price, $12.00. With information on some 380 solvents, this second edition provides a useful source of information on industrial solvents. The text covers physical data and commercial uses and applications with numerous graphs and tables for specific and comparative figures. A new chapter has been added on the safe handling of solvents while chapters on plasticizers and graphic expression and interpretation have been omitted. THE IDENTIFICATIONOF MOLECULARSPECTRA,by R. W. B. Pearse and A. G. Gaydon. Second edition, 276 pages, 20 X 28 cm. New York, John Wiley & Sons, Inc., 1950. Price, $8.50. Much new material has been added in this practical work on the identification of molecular spectra in the wave-length region from 10,000 to 2000 Jl. Generally, new data have been included up to 1947 and in some cases as late as November 1949. More references have been given in view of their usefulness for other purposes than identification. Four new plates containing twenty-six enlargements have also been added. BYPRODUCTS FROM MILK, by Earle O. Whittier and Byron H. Webb. 317 pages, 16 )< 24 cm. New York, Reinhold Publishing Corp., 1950. Price, $6.00. The authors have gathered together in one volume the material relating to the use of dairy byproducts, available in such varied sources as Federal and state bulletins, patents,
