book reviews now and is regularly consulted. There are only a few minor objections which have turned up. Most important, there is no single section on sample introduction and reagent handling techniques. One must flip through each chapter to collect this information. Some of the original electronic circuits are badly out of date; block diagrams would better illustrate the signal processing involved. Finally, there is no author index. This book will certainly become the standard against which future texts on automated and mechanized methods of chemical analysis will be measured. J.

This is a beautiful and, to my knowledge, unique book. It is not merely s compilation of equilibrium constants; it is a thorough and insightful introduction to the study of relative reactivity with collections of equilibrium constants used to illustrate its points. Major emphasis is given to the Hammett equation and its variants, and to the effect of solvent and structure on pro-

ton transfer equilibria. Less extensive treatment is given to Lewis acidity, conformational changes, cyclizations, reactions of multiple bonds, and radical forming reactions. Hydrogen bonding is covered as a suhtopie under proton transfer reactions, sterie effects appear in a number of places, and the idea of hard and soft acids is discussed in the section on Lewis acidity. The book begins with two chapters of general considerations, including a particularly well done discussion of the application of thermodynamics to relative reactivity. Electrostatic calculations are discussed briefly, but the important results are given and the line of thought leading to them is nicely sketched in. Quantum mechanical calculations are only alluded to, hut leading references are given. This appears to be the only weak spot in an otherwise very comprehensive discussion. While the author makes no claims to completeness, his tabulated material is very extensive. Six hundred and sixty references are given. The introduction is dated May, 1974, and some citations to 1974 papers appear. Only for acid-base equilibria and hydrogen bonding are better compilations of data available. This hook should be very time-saving for the chemist with a new theory to test. It will make even less excusable the use of a small, subjectively chosen, body of data. The book was developed as a teaching text for advanced undergraduates and heginning graduate students. It should be readily understandable by anyone who has a reasonable grasp of the material of firstyear organic chemistry and physical ehem-

The analyst, particularly in industry, often needs to know not only the total amount of an element present in a substance hut also the amounts in various oridation states or in certain combined or mineralogical forms. This hook is a sunmary of the puhlished methods for making these differentiations quantitatively by chemical means for 34 elements. The author has also added suggestions for practical manipulations based on his own experiences in the field. While primarily for the industrial analytical chemist, the book would be a handy reference work for students and their professors. I t contains en index and an author index of literature citations.
