This volume is the sixth in a series edited by Professor Paul Delahay and Charles W. Tobias. The present volume, edited by Professor Delahay, at the very least maintains the high standards of excellence established by its predecessors in the series. All of the five chapters were written by authors of eminent qualification and reknown in their respective fields. In this reviewer's opinion, all but one of the chapters must be considered distinctive on one or more counts.
The reader is assaulted with a tour de force of the first magnitude in the opening chapter by C. A. Barlow, Jr., and J. Ross MacDonald on Theory of Discreteness of Charge Effects In the Electrolyte Compact Double Layer. The subject in question is both difficult and specialized, yet highly important to most areas of electrochemical science. The Barlow-MacDonald review and treatment of this frontier area is masterful indeed. One has to admire the authors for the supreme effort they must have devoted to organizing this 199-page manuscript from the many difficult-to-read, often contradictory publications in the area. This chapter is likely to be heavy going to most readers, particularly the mathematically weak-at-heart. However, the authors have generously mixed much eminently readable prose between mathematical arguments to inform the reader of the underlying reasoning and conclusions. This reviewer must confess to being unqualified to judge the soundness of most of the quantitative treatments, but the quality of the qualitative presentation is above question. As a review, critique, and presentation of original concepts, this work must be considered first class.
The Oxygen Electrode on Noble Metals by J. P. Hoare distinguishes itself in the thoroughness with which it reviews one of the most extensively investigated subjects in modern electrochemistry. By good organization and a concise style, the author managed to compile, discuss, compare and render incisive judgment on a vast body of information dealing with the oxygen electrode reaction utilizing just 87 pages. The coverage encompasses contributions dating back to the turn of the
century, but emphasis is placed on the more up-to-date research.
The chapter on Electrochemical Kinetics of Metal Complexes by Jiri Koryta is the only contribution in this volume which this reviewer does not consider distinctive. The subject in question is of sufficient scope that it easily could have been accorded a 100-200 page treatment, particularly if the author considered the many exciting developments in relevant methodology and theory. Instead, Dr. Koryta chose to confine his discussion to a short (38 pages) treatment of certain important recent developments. In fairness to Dr. Koryta it should be mentioned that this subject has been reviewed extensively of late and Dr. Koryta has contributed in excellent style to these recent reviews. With this in mind, the fact that he decided to confine the present chapter to discussing just the most recent developments in certainly defensible. The lack of scope of the chapter prevents one from considering it distincth'e, but it is otherwise well done.
The fourth chapter on Electrochemical Response of Porous and Rough Electrodes by Robert de Levie deals
with a subject whose importance to users of solid and porous electrodes is exceeded only by its mathematical intransigence. Professor de Levie has a well-established flair for attacking such difficult electrochemical mass transfer problems with delightful elegance and sophistication (at least by this reviewer's standards). The present chapter is no exception. Basically, it considers in detail the general theoretical problems associated with calculating the current-potential distributions at electrodes whose geometry for mass transport is irregular, with emphasis on the obvious cases ; the porous and rough electrodes. However, even the polar-ographer who recognizes only the dropping mercury electrode will find something of interest in this excellent chapter.
Insulator Electrode Reactions by W. Mehl and J. M. Hale was probably the most intriguing chapter to this reviewer, simply because it deals with a rather new area which is quite foreign to most electrochemists, yet eminently interesting as presented by the authors. Mehl and Hale have treated this subject in a manner which makes readily understandable the basic principles and
