the text was $12.50, but recently it was $15.75 a t our local university bookstore. The original text sold ataprice far beyond practicality for course assignment.

The appearance of a modern version of C. A. Coulson's book "Valence" is long overdue, and the revision, appearing with the title "Coulson's Valence" under the authorship of Roy McWeeny is certainly welcome. I n providing a current exposition McWeeny has maintained the style and clarity so prized by Coulson. The frequent use of diagrams is continued and although certainly not a mathematical treatment, elementary mathematical statements are used when aooroorinte. Rouehlv half the book is eswnt~nllyas Caulson left i t , lmt McWeeny has nlw undertaken strhrtantiol reorganizatiun and expansion ot many \ertions. Two new chapters, several long sections, a selection of problems, and three appendices have been added. The first three chapters, which carry the reader quickly from a glimpse of the foundations of quantum mechanics through ta the notion of an electron wavefunction, are, as might be expected, largely unchanged from Coulson's second edition. The fourth chapter, an introduction to the elements of molecular orbital theory, is modernized and retains the streneth of the earlier versions.

In the last third of the book McWeeny, as did Coulson, attempts to cover a number of rather major but less connected topics. The first of these is Chemical Reactivity to which MeWeeny devotes an entire chapter. The application of molecular orbital concepts to reactivity has grown enormously since the last edition and indeed McWeeny's exposition is still rather soarse when one considers the impart on contempnmry work of Woodward Hoffman rules.

separate treatment of metals and nonmetals. An expanded treatment of band theory is a sienificant and welcome feature of this c v h a p ~ ~ r .In the penultlmnte chapter. McWeeny treats weak intrmctions and un. usual bonds (hydroten bon~lr,rnre gas cum pounds and the like) a contemporary version of topics of current interest which continue to intrrgue. The final chapter reviews, rather cursorily, the enormous scope of modern self-consistent field theory applications. McWeeny has also included appendices on probability, angular momentum, and group theory which complement the material in the body of the teat. Over 5090 of the literature cited hy McWeeny has appeared since Coulson's last edition. However, most of these citations are from the sixties and early seventies-there are none more recent than 1977 and indeed only a dozen are from the 1975-77 period. As a result some recent developments have not received the discussion one might have exnected. This is true not onlv of the mare esanteria: topics-the phcr*phmitriles, for example, I,ut also of mow fundamental areas such ns transition metal rhcmirtry. Netertheless, as an elegant contemporary statement of our understanding of chemistry, "Coulson's Valence" has very much to recommend it. Chemists will continue toanswer questions by saying-'% is in Coulson." W. G. LAIDLAW Univwsily of Calgary Calgary. Alberta

Application of Zeolites in Catalysls G. K. Boreskovand Kh. M. Minachev, (Editors), Akademiai Kiado, Budapest. 1979. 179 pp. Figs. and tables. 24.5 X 17.2 cm. $15.00. "Application of Zeolites in Catalysis" edited by G. K. Boreskov and Kh. M. Minachev contains plenary reports given by Soviet scientists a t the First All-Union Conference on Application of Zeolites in Catalysis held in Novosibirsk in 1976. Therefore, this book is unsuitable as a text a n zeolites but makes a useful reference especially on the subject of Soviet advances in the area of the utilization of zeolites in the oil-refining industry before 1976. There are eight chapters in this book. The first chapter, Zeolites and Catalytic Syntheses by Kh. M. Minachev is a general review of the types of reactions involvingzeolites in catalysis. Reactions of paraffinic, olefinic. and aromatic hvdrocarbons in the presence of zeolites arc discussed. Other resrtions included in thi* rhnpvr are olefin hydnhrmylatmn, synthesis of acrylates, preparation of esters, isoprene syntheses and many other types of reactions. None of the reactions are discussed in detail. Examples of the selectivity of zeolites are given in this chapter but no details are given in explaining the causes for such selectivity in any reaetion. The second to fourth chapters deal primarily with the role of zeolites in the oil refining industry. These chapters include: "Soviet Zeolite-Containing Catalyst for the Cracking of Petroleum Fractions," "Catalytic and Acid-Base Properties of Zeolite Systems," and "Factors Determining the Activity and Selectivity of Zeolite-Containing Cracking Catalysts."
