Thé ; only work on electrolytes which covers both theory a n d experiment comprehensively! JL his is the new edition of an authoritative treatise on the theory and properties of strong and weak electrolytes. Recent advances in the field have been fully covered in a lengthy appendix. Among the subjects given particular attention in this appendix are the ionization of weak electrolytes in salt solutions, the dissociation of strong and moderately strong electrolytes, diffusion, conductance, ionic hydration, the extrapolation of apparent molal quantities, and extensive new data o n activity coefficients. Revised values of the physical constants (Birge, 1941) and new information regarding the temperature and pressure variations of t h e dielectric constant and density of water have been used t o revise and considerably extend the tables of theoretical coefficients and limiting slopes. Formulae and tables are presented for easy and accurate extrapolation of apparent molal quantities. The presentation of the theory is unusually complete, and includes the treatment of all of the thermodynamic properties of ionic solutions as well a s conductance, frequency and field effects, viscosity, and diffusion. T h e theoretical equations are reduced to their simplest forms, and numerous tables are given. Great emphasis is placed upon modern experimental methods and the most accurate results. Among the topics covered in detail are conductance, transference, viscosity, diffusion, ion association, frequency and field effects, thermochemistry, piezochemistry7, partial molal quantities, freezing points, boiling points, vapor pressures, and galvanic cells. T h e last five chapters deal with the properties of solutions of hydrochloric acid, 1-1 electrolytes, polyvalent electrolytes, mixtures of strong electrolytes, and weak electrolytes, respectively. Here is a book that's worth its price many times over as an important addition to your working reference library.

CATION EXCHANGE IN SOILS (ACS Monograph) By Walter P. Kelley This Ions-needed treatise explains how one of the most important phenomena of the soil—cation exchange—takes place and how the exchange process affects the soil. Every known phase of cation exchange is discussed, including origin and history, evolution of concepts, the several theories, basic principles ana their relationship to soil types, soil properties, fertilizers, soil acidity and alkalinity, plant nutrient and geological processes.

Monograph}
By Louis F. Fïeser and Mary Fïeser This book is addressed not only to chemists, biochemists, and medical investigators directly interested in this specialized field, but also t o workers in other fields, who now have easy access to a wealth of new techniques of experimentation, new schemes of synthesis, and new theoretical concepts that have resulted from the spectacular advances in the chemistry of the steroids and related products.
