Methods of preparation of all reagents are either given in detail or the original reference to the literature is given. Compounds are listed conveniently in tables in order of increasing boiling point or melting point, and the arrangement of homologous series is that used as the order of study in most argttnic textbooks. In general, although marc derivatives are listed than in American texts on identification of organic compounds, fewer compounds are included. For example, one prominent text lists 10 derivatives of 146 alcohols while Wild has 14 derivatives of 57alcohols; in the same book are 98 phenols and 13 derivstives while Wild has 58 phenols and 18 derivatives. The author index includes all men whose papers on idontifiosr tion are included in the text. There is an adequate subject index. This hook will he placed on our reference shelves at once. LEALLYN B.

title of book) are omitted. The "new" method of producing phenolic resinoids is illustrated by a. flowsheet reproduced from an article published in 1927. Some of the details relating to east, phenolic resins rare inaccurateat least for the major produetion of this type of resin. In general, this book is characterized by the uninhibited mthusiasm of the author for the marvels and potentialities of plastics rather than by a clear, scientific presentation of the chemiaal and mechanical processes of the industry. The author's expression often suffers from loose construction and his meaning is frequently obscure. Much of the material found in this volume is excellent for reference or instruction. Its reliability is limited by the presence of numerous inaceuraoies or the lack of adequate proofreading. Glaring evidences of the latter are the impossible structural formulas, p. 201 (final), p. 231 (both), and the footnote on p. 221. H. A. NEVILLE

T ~ r is s another textbook resulting from a course in plastics for workers in World War I1 industries. It is organized in the usual pattern for a comprehensive survey of the subject: sections on thermosetting, thermoplastic, and cellulose plastics; chapters on synthetic rubber, resin-bonded plywood, and mold design and equipment. This hook includes, or is largely based upon, technical data, information, and photographs supplied by manulacturers in the plastics field. The author, in his acknowledgments, refers to this cooperation as the release of new and restricted material. However, for example, the "release" on "Cycleweld," covering

LABORATORY EXERCISES IN INORGANIC CHEMISTRY
W. Norton Jones, J r , Professor of Chemistry, Colorado State College of A B M Arts, Fort Lewis Branch, Hesperus, Colorado. The Blakiston Co., Philadelphia, 1947. 315 pp. 20 X 28 cm. 20 figs. THE paper-covered manual includes 50 exercises which, as the author states, are not original and which are, for the most part, those generally used in freshman work. The last 208 pages are devoted to problems for each exercise. Many of the experiments to be performed by the student would duplicate those seen by him in tho demonstrations normally performed by the teacher during the lecture period. 8. 1884 L ~ R BCINYO~P L BO~EVABD'
