447 self why earlier books with the same titfe have required hundreds of pages to cover apparently the same ground. “Electrometallurgy” and “Corrosion” are dismissed in similar order and the book ends very lamely with a thin chapter on “Electroorganic chemistry”. To attempt to cover this in seven pages is little short of naive and the matter is further confused by the insertion of a few pages on both Fuel Cells and Industrial processes treating the inorganic as well as the organic aspects of the latter in precisely one smal1 page. This is perhaps the most inhomogeneous book one has seen for some time in the field. There are two chapters (3 and 4) which will be of much use to working electrochemists. But the beginning and the end, with its fairly deep (and yet not broad) electronic theory can only have Iimited appeal, while chapters 5-8 range from mediocre to pathetic. All of this will make it, for most readers, a book to borrow (to see whether there are any smafl “tips”” worth having) as opposed to the vade mecum which must be constantly at hand, A. T. K.

This book is part of a series on physical chemistry and chemical physics. The book contains material which to quote the author “are likely to resist the attacks of time”, or are “of general validity”, The result is an orthodox lay-out of subject material competently written. The Editors-in-Chief of the series have stated that particular importance should be given to the exposition of the fundamental bases of each topic and to the development of the theoretical aspects; and that experimental detaits of an essentially practical nature are not emphasized. This has resulted in a book impeccably grounded in logic and beautifuhy presented but which would be of much greater value to the student in the subject if the experimental methods were also given in more detail. The author however has a brief within which to work and this he achieves. The first chapter contains an introduction partly historical and partly a description in outline of important aspects of the subject. The remainder of the book describes these aspects in detail. The second chapter deals with the mechanics and thermodynamics of the interface. It then goes on to deal with the theory of Gouy, Equations of State and the Origins of the fnterfaciaf Tension. The remainder of the book deaIs with various systems. The AgI/soIn interface is an example of a reversible interface, the Hg/soIn interface can be considered as almost ideally polarizable. The treatment of double-layer systems formed in solutions of surfactants in water or in aqueous electrolytes is the subject of a separate chapter. The electrical double layer at semiconductor surfaces also rates a chapter and includes data from LEED and AES. This is a well constructed book and deals with the subject in a comprehensive manner.
