use more initative; more unknowns and experimental problems. New experiments included in this edition include those on elution and paper-strip chromatography, enzymatic and spontaneous resolution, formation of geometricalisomers, and cost cslculatiotions. In this reviewer's opinion, the text will serve admirably for the undergraduate organic chemistry lahoratory. It may be used also as a constant source of help for graduate students in research. The Instructor's Manual (23 pp., available for 406) will prove especially helpful in planning organic laboratory work as it has a rather complete list of chemicals needed, suppliers, and up-to-date prices. Also included are many helpful suggestions wit,h regard to the experiments included in the text.
is extremely well covered. But the principal value of the book lies in its particularly appropriate method and plan of presentation and in its lucid style. The reader soon feels that an attempt is made to help him solve his problems, rather than to force upon him artificial problems for which statistical solutions happen to exist. The introductory first chapter is followed by one entitled The Planning of Simple Comparative Experiments, which is an excellent, though brief, exposition of the main principles underlying the st.atisticd method. Chapter 3, entitled Sequentid Tests of Significance, while interesting and important, can be omitted in s. first study of the subject. Beginning with Chapter 4 the reader i8 gradually led into experimental designs of increasing complexity.

THISbook, which is the joint work of George E. P. Box, Lewis R. Connor, Wilfred R. Cousins, Owen L. Davies, Francis R. Himsworth, and George P. Sillitto, marks animportant milestone in the application of statistics to the phyeical sciences. With a single exception, noted helaw, the field of statistical design
SOMEproduction methods for producing small parts are discussed-e. g., castings, forgings, extrusion, powder metal parts, spinning, electrofonning, bonded, molded plastics, and formed, nonmetallic materials. Cost, production, and design factors are discussed.
