with the field will probably find aomething new; the reviewer was particularly intrigued with the estimation of the density of t,he mosquito population by isotope dilution of radioactive mosquitas, bred in P* and released to mix with wild ones. Besides the extensive discussions of the usual &tope techniques (with heavy emphasis on the tracing of genetic material, protein biosynthesis and metabolic pathways in general) there are sections on the chemistry and physics of isotopes, their methods of preparation, units of measure (curies, roentgens, atom percent excess), health hazards, and separation methods. Every single section of the book is highly recommended. Excellent references for further reading are appended to each chapter, and the material is right up-to-dateat least one reference to 1964, and many from 1962 were noted. Only one minor typographical error was observed. PETEROESPER Hahnemann Medieal College Philadelphia, Penmylvania
enoyclopedia particularly valuable since information of this type is difficult to find in the usual pure chemistry or chemical engineering literature. The topies range from scientific discussions of chromatography, colorimetry, and color photography to process descriptions of chlorine and industrial coatings to the mechanism of blood coagulation. The international flavor is retained, for example, in the extensive review of the properties and production of coal by a British author. Thus, the encyclopedia has continued its high standards of presenting valuable reference material and should he a standard item in a chemical library.

will save the researcher in the field many hours of literature searching. While this book was probrtbly not written primarily for use as s. college text, it is of sufficient value to be constant reference material, pmticularly on the graduate level. The rewewer feels that this work, especially section I, should be a part of the required readings for all advanced students of chemist,ry and should indeed be in the library of all chemists involved in analytical chemistry. From a nontechnical viewpoint, the book is well written with very few errata noted. While the latter section of the book is necessarily a compihtion of amperometric titration methods, and is not, therefore, the type of material which one sits down to read casually, the first section is a pleasure to read hoth casually and in depth. The aut,hor is to be commended for his contribution to the literature in the field of electroanalytied chemistry

This compilation of tables presents the stability constants of both inorganic and organic ligands as they are reported in the literature through 1960. A table for each ligmd lists the constant for each metallic ion, along with the method of determination, the temperature, the medium, and the original reference. An index of inorganic and organic ligands by name and an index of metals are included. An earlier version of this work was published in two volumes during 1957-58. This edition has been expanded to include some alder data omitted in the first publication and includes redox equilibria. and the extraction of inorganic ligands into nonbqueous solvents.

John Stock has produced a volume filling the gap which has existed for some time in the literature covering electroanalytical chemistry. The fields of polarography and potentiometry have been well covered in the various excellent books available in these fields. However, until the present volume, the field of amperometry in this country has lacked a single comprehensive source book covering hoth the theory and applications of this widely used and often underrated analytical tool. Dr. St,ock has succeeded in plvducing a hook which will be considered a "must" on the bookshelf of all analytical chemist,^. The book is divided into essentially two sections. Section I deals with t,he principles, apparatus and general techniques requisite to the intelligent use of amperometry. The aut,hor has succeeded in presenting the subject matt,er in a fashion understandable to the neophyte and yet in enough depth to make it of interest to the "pro" in the field. Of special interest is the presentation of amperometry in all its various f o r m and the manner in which the relationship of amperometry to its close cousins, pobrography and potentiometry, is shown both mathematically and dkscriptively. The second section of the book is devoted to the applications of this technique to analytical chemistry problems, divided somewhat arbitrarily into two parts; the first dealing with the various precipitation and eomplexometric reactions and the second with the oxidation-reduction re-
most comprehensive and thorough review of amperometric methods published to date. Pasta of this will be of special interest to organic and biochemists since techniques are described for the amperometric titration of s. variety of organic compounds. The bibliography is especially good with world-wide coverage up to and including 1963. This feature alone

Dr. Star$ has providedus with a volume on the liquid-liquid distribution of neutral metal chelate compounds and the factors influencing the formation and partition of these substances. The first of t,he six chapters is a very brief introduction to the Nernst distribution law and the properties of neutral metal chelates which make them subject to extraction. The second chapter treats the general association m d partition equilibria involved in chelate solvent, extraction, the treatment being patterned largely after the approaches of Rydberg and Irvins. The third chaoter discusses the influence of extraction system variables on the character of the extrsetions. Included artre the influences of acidity, of chelating agent concentration, acid dissociation constant, and partition coefficient, of the metal chelate diaeaciation constant and partition coefficient, of masking agents, of the organicsolvent, and of kinetic faotors. The fourth chapter describes severel analytical applications of the solvent extraet,ian of metal chelates. And the fifth chspter sets out the metal extracting charaeterist,ics of about 100 different chelating agents, some of them having been investigated with as many as 55 metsl ions. The sixth and final chapter claims to present the most selective prvcedures for the metal chelate solvent extraction isoletiom of 48 met,als. I n addition, there is an appendix giving acid dissociation constants and distribution eoefficjents for 51 ehelating agents. Over 1100 references are cited and the literature
