by all gasphase experimentalists. The format of the first edition has been largely maintained, except that the discussion on the control of pressure and temperature has been separated and enlarged into two chanters. as has the discussion on the preparation and analysis of gases. The remaining three chapters, as previously, comprise a summary of the principal formulae, laws, and data pertaining to the kinetic theory of gases, a full account of photochemical techniques including a new section on flash photolysis, and a chapter on further experimental methods of investigating gas reactions, detailing methods which have been developed for the study of specific systems. The brightest feature of the book is that it is replete with references a t the end of each chapter (totalling over 1500), plus an extremely up-to-date bibliography of more than 50 monographs, hooks, and articles. The litersture is comprehensively oovered, rtnd references as late as 1963 may be found. I t is thus especially suited for beginning research students in gas-phase kinetics and photochemistry, and to a lesser degree for those interested in general vacuum techniques and the handling of volatile materials. I t d l , as did its predecessor, find a n invaluable place in the lithoriltaries of all gas-phase kineticists; the binding appears to be average for this kind of use. I t is unfortunate that the price of 517.00 will dissuade most students from purchasing the book, and its ready aveilability to them in the laboratory will

This section of the cobalt supplement contains the chemistry of the complex compounds of trivalent cobalt. Literature references M recent its 1962 are included and the bulk of the material has been published since 1930. The volume is divided into two main parts and a reference section. The major portion deals with the compounds of Co(II1) with neutral ligmds and the polynuclear structures. The %mines(1-6 ammonia, hydroxylamine, or organic neutral ligands) are covered in approximately 100 pages. The octahedral configuration of all Co(II1) co. .plena leads to many cases of optical activity which are thoroughly documented. A second section describes the inner complex compounds-those that have ligands bound to Co(II1) simultaneouely

Isotopio kinds of water are the principal subject of this volume. Other topics iucluded are the electrochemical behavior of water, systems of water with oxygen and organic solvents, and water ions. Literature is reviewed through 1949, and mare recent unevalusted references are included. Eighteen isotopic farms of water are mentioned; however, D1O is the only type extensively covered.

This book, whieh is the eighteenth in the Pergamon series of monographs on t,opics in analytical chemistry, is a concise and coherent presentation of all aspects of precipitation kinetics, a specialty in which the author is an acknowledged authority. Most textbooks of analytical chemistry give brief diaoussions of nucloation and crystal gmwth, hut these discussions tend to he shallow, if not wrong. Therefore Nielsen's hook should be of interest to teachers of analytical chem-

where such growth is controlled by diffusion, surface nucleation, or screw dislocations, or by certain combinations of these mechanisms. Chapter 7 discusses the complicsted general case of precipitation as a, result of homogeneous nucleation. Chapter 9 deals with the kinetics of Ostwald ripening and of coagulat,ion of colloidal precipitates. The other four chapters are rather brief, and are concerned with precipitation with a generating process (wch as precipitation from homogeneous solution), the effects of seeding and the kinetics of dissolving, t,he influence of the crystal growth meohanism an the finalshapeof the ~ s t a l sand , the effectsof adsorption. The author also provides an excellent bibliography of hooks and papers, whieh covers the literature through 1961. The author derives chronomals, or chronometric integrals, relating time to the fraction precipitated, for the various growth mechanisms; these chmnomals may then be applied to experimental results to determine which mechanism is raie controlling. A number of charts and tables are included, to aid in the curve fitting. The nature of the material covered, and the depth of the coverage, would have justified a. much larger volume, and the major flaw of this hook is its brevity. The derivations and discussions are too condensed to be followed easily by one who is not already a. specialist in the field. More detailed discussion of bhe ttpplicetion of theory to experimental results would also have been helpful.
The hook contains a few minor printing el(*ors. Nielsen's book will probably be of litt,le use to undergraduates, but should prove to he extremely valuable to people with advanced training who are interested in this quite difficult ares. af analytical and/or physical chemistry.
