in the 810 pages of the volume. The book is not intended as a text and would not be suitable for that purpose. I t does, however, provide a n up-to-date (1976) survey of a variety of aspects of solid-state reactivity. Mast of the experimental methods currently used in investigations of solids are illustrated in one or more of the contrihutions. Overall, the book presents a good picture of the "state-of-the-art" and cites a number of areas where further investigation is needed. It is especially appropriate as a reference volume for libraries of institutions and individuals involved in solid-state resemh. Charles W . Owens Univwsity ot New hmpshire Durham, N.H. 03824

Physics meth~dologyin science overlaps with chemical methodulogy nhen solutionr to prohlema are suught by analogy and by approximation. The use of models and simplification become necessary when closed solutions cannot be obtained and provide not only useful qualitative and semiquantitative information-but help pave the way for imoroved theories. Since much useful information in chemistry can ire ubtaincd hy assuming the validity of simplified f u r m ~uf quantum mechanics muchattention haialw been given t o numerical analysis aided by digital computation. Still the need for qualitative approaches in chemistry will continue t o persist. This is due in part to limited computation technology and on a deeper level t o a lack of basic understanding of the real essence of chemical structure and reactivit."~ --, Migdal's book, written for physicists, presents basically the physics methodology for obtaining qualitative and semi-quantitative solutions to quantum mechanics problems. Chemists with interests in the areascovered will find the book quite useful. The first chapter entitled "Dimensional and 'Model' Approximations" forms an introduction to the remaining chapters by treating in separate sections purely mathematical estimating techniques (such as the method of steepest descents), model and dimensional approximations in atomic physics (such as the Thomas-Fermi method), and approximation techniques used when the radiation field is considered (such as quantum electrodynamics). Of the remaining five chapters the most familiar to the majority of chemists will he chapters two and three dealing with perturbation theories and the quasielassicsl approximation. Material related t o spectroscopy and scattering theory will be useful to those interested in these fields although the treatment is definitely physical rather than chemical. Further topics in scattering theory are developed in chapter four by investigating the analytic properties of the scattering amplitude. The last two chapters on methods

Three skipped years during the Depression and World War I1 caused t h ~ 50th s one to be delayed till 1976. Almost 500 people, close to a quarter of them from abroad, attended and over 250 papers were presented.
