Bitumens are discussed in the light of their origin, preparation, distinctive characteristics and utilization. Special attention is given the manufacture of varnishes and lacquers with a view to anticipating any subsequent difficulties during and following application. Chapters on Paints and Enamels and, Cellulose Ester Products complete the roster. A number of useful Tables have been added. These classify the pigments according to their durability, composition, physical and chemical properties. Oils, solvents and resins also are tabulated according to their various characteristics. A Glossary of the pigments with their respective compositions is included and should prove a real help to those concerned with the manufacture of paint. T.

CHEMICAL ENGINEERING CATALOG, I934 (Nineteenth Annual) edition, collected, condensed and standardized catalog data of equipment, machinery, laboratory supplies, etc., with classified indexes of such equipment and materials, carefully cross-referenced and a technical and scientific books section . . . 779 pages, 2I X 29 cms. New York, Reinhold Publishing Corp., 1934. The 1934 (Nineteenth Annual) edition of the Chemical Engineering Catalog is now on the shelf. The new Catalog is positive evidence of its Committee's successful efforts to improve it in the face of prevailing unfavorable business conditions in the chemical industry. T h e work of persuading manufacturers to include complete catalogs of their products brings greater results each year. More and more data on the properties and applications of listed chemicals are to be found and the Committee expects to enlarge upon this yearly. A manufacturer or user of chemicals will find the Catalog practically indispensable. In the front (page IO) will be found a Trade Name Index telling the nature and maker of various types of equipment and manufactured products. Following the Classified Index of Equipment and Supplies are the individual catalogs of the manufacturers. Although the Section on Chemicals and Materials does not enjoy the magnitude of the one preceding, it nevertheless carries a complete list of the items industrially available today. It also is a great convenience to have the Laboratory and Reagent Chemicals grouped together. Every year the Technical and Scientific Books section is revised and brought up to date. We would like to see more publishers of technical and scientific books joining this section. T. K. CLEVELAND. FARADAY, by Thomas Martin, 143 pages, 12 )< I9 cms. London, Gerald Duckworth, & Co., 1934. Price 2 shillings. So often the biography of a great scientist is written by someone who has followed the same or a similar pathway. In such events, the scientific nature is apt to be stressed to the point of excluding other equally interesting phases of the character of such a great personage. We do not know whether the author of this book enjoys scientific pursuits, but if he does he has not permitted such propensities to bias an attempt to present a well-balanced appraisal of Michael Faraday. This pocket-size volume is number ~Q~ty of a series of Great Lives. It is written in a t-~an0eK that, r epfl~s k'~ e#t~rtsining to scientist and layman alike. °.e
