" S u l f a Bondinz." the Ronald Preri company, New YO& 19621 deals with valence, orbitals, divalent sulfur, sulfones, sulfoxides and sulfanium salts, but changes in the field since 1962 certainly warrant this more extensive coverage. Many other books that cover special or purely research topics have usefulness in graduate m u m s requiring specialized rather than general emphasis. Among those with some overlap of topics are "Mechanisms of Sulfur Reactions" [Pryor, W. A,, McGraw-Hill Book Company, Inc., New York-San Franciseo-Toronta-London, 19621 and "Organosulfur Chemistry" [Janssen, M.

The 28 chapters of this hook represent as many lectures given a t an International Symposium on Electrochemistry honoring the accomplishments of Professor J. O'M. Bockris, held a t the Imperial College, London, April 3-61975. The plan for this symposium, and hence for the book, was unusual in that it featured pairs of invited addresses, one t o summarize the "state of the science." and the other to suggest directions for future research in particular aspects of electro-
chemistry. In most topics, a third speaker has attempted to integrate or summarize the material presented by the first two, perhaps adding some thoughts of his own. The last (and longest) chapter is a "Synopsis" by Professor Bockris, in which he summarizes the many important contributions from his laboratories, which were successivelylocated s t the Imperial College, the University of Pennsylvania, and the Flinders University of South Australia. The topics covered are: electrochemical energy conversion, bioelectrochemistry, electrocatalysis, kinetia of electrode processes, semiconductor electrodes, corrosion, electra-organic chemistry, electrometallurgy of aluminum and other metals, mineral processing, and high-temperature electrolytes. In addition to these more-or-less conventional subjects, is a series entitled "Electrochemistry for a Better World," concerned with energy conversion and storage in a post-fossil fuel society. As one might expect, there is considerable variation from one author to another in stylistic matters as well as in depth of coverage; some chapters are much easier reading than others. same are hiehlv .. ,theoretical while
