BOOK REVIEWS c d are given in the hack of the hook. Unfortunately, the author nowhere makes any mention of significant figures and is not consistent about them in the answers t o hi8 problems. He also is careless about the inclusion of dimensions and units in his otherwise good examples. The appendix contains nine tables of useful information and data. The L i t of suggested readings supplied in t,he 1958 text has been dmpped from the newer book. Probably the students do not miss this, hut their professors might. Theoretical sections are up t o date and used as an admirable means to demonstrate the productivity of logical reasoning based on valid principles. While not technically incorrect, one wonders why the author deviates from the usual usage in reference to the hydrated proton. He seems to prefer to consider i t s protonated water moleculr, calls it the oxonium ion, and writrs i t OH8+. This book will he quite satisfactory as s. text in introductory courses where the application of common sense reasoning is stmssed and emphasis is placed on major chemicnl principles rather than on the chemical propertips nf t,he clrments and their compounds.
