Lastly, there is n list of supplemer~tary ~.eferences ill earlier voh~mesto those cited in volwnes 21 and 22. The reviewer finds this a. valuable index, serving t o pinpoint significant earlier references qnickly. Preceding the main section of the text is a six-page r.eview of most recent methods under the title, Trends in Synthetic Organic Chemistry. References are cited from 1967 (53%) and 1968 (45%), which is evidence of the effort the editors made t o keep abreast of new developments. The formal scheme of organization in the text is still somewhat of a deterrent t o wage of the Theilheimer series, but even browsing through the book is rewarding. T h e text is remarkably free from errors. The price of the book is steep in the reviewer's opinion, but who can evaluate the worth of chance associations? ERNESTI.

menbioned above on solvent extraction and fused salts. References follow each chapter, and after most chapters are some thonght-provoking exel.cises. Tho book is experimentally oriented; the aobhor refers to experimental mmip~dations,actual prncmes in the lnborator,~ and in industry, and gives drawings and diagrams of apparatus. At the same time the theoretical or conceptual fr.amework for understanding the snbject is well presented. Thus, early in t,hehook t,heauthor outlines and elucidate5 the ides. of "salvenl system" and the interrelation of the ionization process in the solvent t o the ident,ifieation of acids and b a s e in the system. However, he is careful to warn against the overextension of such guiding idea-, noting with an example from the phosgene system that the presumed neut,raliaation of calcium chloride with alominnm chloride in that solvent clearly involved other processes, as demonstrated by tracer studies. The general choice of topics used as illustrations in each chapter is good, the emphasis being less on mlvent system formalism and more upon exploring diverse chemical topics such as reaction mechanisms or upon less-conventional ideas such a? hydrocat.bons a< acids and baqes. Possibly becalm of t,heir greater unfamiliarity or because of the aut.hor's greater enthusiavn for the subjects of the Isst two chapters, the reviewer found these t o be the mast interesting and 1,esearehoriented. Among the topics discussed are spectra of metal ions in molten salts, and solutions of met,als in molten salts. The most recent reference the reviewer found was dated 1966. The boak has an adequateindex. For the reader who wants t o know somet,hing about fairly recent developments in non-aqueo~ts salutio~l chemistry but does not have t,ime or opportunity t o plough through detailed monographs, this book should open some new vistas and give him some ncw ideas for experimental work.

Zingaro's "Nonaqueous Solvents," a title in the Heat,h "Topics in Modern Chemistry" series, is similar in content and level t o Sisler's earlier (1961) "Chemistry in Non-Aqueous Solvents'' (Reinhold); there are enough differences and modern additions in the Zingaro book t o warrant a student or faculty member having both. The differences lie principally in the last two chapters, which treat liquid-liquid solvent extraction and fused salt systems. The chapter headings adequat,ely indicate the contents of the book. After a n introduction and some attention to the properties of water a q a solvent and to r l a d k a t i o n of solvents, the boak treats acid5 and bases and some theories dealing with t,he behavior of solntes in non-aqueoos solvents; liquid ammonia an a solvent,; anhydrous hy-

According to the preface, this hook is designed as a text for a first caumo in quantum mechanics. Because of its length (180 pages) i t seems particularly suitable to be used in the first term of a year course. I t is qnite good in discussing the postulates of quantum mechanics and the elementary standard applications such as a. particle in a. box, the harmonic oscillator, angular momentum, and hydrogen atom. As the book progresses into a~oroximate methods and the vsriow -~~~~ . pert,urbation theories, however, it becomes somewhat hrief for a text, in an inbrodoc-

Jlowever, this was meant lo he a brief text. 11,spite of the conciseness tho aulhnr has managed to at least introduce a number of modern concepts and teehniqoes. Ovel.all this hook is very enjoyable to read, seemingly quite free of errrm and very slraightforward and deal.. The most striking featwe, and one that differentiatw it fmm several other hooks nf this type, is the qnnlity of the p~.ohlems. Each chapter is followed by a set of pl.ohlems, slmust evelyme of which ia phwically interesting and illustrates and leaches some physics. ScvewJ of the problems even have references to recelll, literntwe, which is certainly not easy to du in a hook of this level. The author ha.; done a very fine job in the choice of the piddems. In summary then, this ia a bvief introductory text in qosntorn mechanics which packs s great ammmt of matel.ixl into 180 pages and if i t is too concise lo he a principle lext in a course, it is admirably suited as a supplemental.y text, pnrticw Inrly since there is a p n p e t h c k edition fov m l y 84.95.
