HANDBOOK OF MATEEMATICAL TABLESAND FORMULAS.Rkhard Stevens Burington. Ph.D., Dept. of Mathematics, Case School of Applied Sdence. Handbook Publishers, Inc., Sandusky, Ohio, 1933. iv 251 pp. 57 Figs. 13.5 X 19.5 cm. $2.00. Special price to students and teachers-$1.25. Burington's handbook aims "to meet the needs of students in mathematics and other subjects requiring mathematical computations" . and "to supply the mathematical requirements of the workers in other fields of science, such as chemistry, physics, and engineering." The detail with which the mathematical formulas and the explanations of the tables are presented should assure the fulfilment of this aim. The material in part one may serve as an outline for a general review of the elementary branches of mathematic;, including vector analysis. From a chemist's standpoint, however, there is little useful information in this handbook that is not already available in chemical handbooks. TBBUNIVBPISIN OR WISCONSIN PAUL C. CROSS MADISON.

Twenty other no less distinguished chemical engineers write on a quarter century's trends in their particular fields which range all the way from chemical engineering education t o water, sewage, and trade waste treatment and from acids and heavy chemicals to sugar, paper, glass, and paint making. As a broad and fascinating portrayal of the whole development of chemical engineering in America in its myriad forms, this volume has a place in the library of every chemical engineer, in the plant and laboratory reference room, and in the schools and colleges where the embryo chemical engineer first envisions the career that lies ahead in his elected profession.
