Analysis will show that all major criticisms of the book hinge essentially on its brevity. The teacher has constsntly the feeling that the treatment, if not inadequate, is certainly sketchy; that too much is left unsaid. Yet how much can be said in just275 pages of large type (12point)l But remember, Csrswell's purpose is an "Introduction," a. hook for the non-specidist. Operating within this framework, he keeps it simple, and acquits himself well. WILU~M H. JONES E m ~ University y Atlanta, Georgia
In general the author has presented a satisfactory outline of the reactions of free radio&. T h e n are, however, many sections wherein the discussion should be treated with reservation. For example, the discwion of 1,Zhalogen migration does not even mention the alternate, and often preferable, elimination-addition mechanism. GLENA.

This hook is a corrected printing of the 1964 edition. I t is part of a series aimed at first- and second-year college students and presents a concise qualitative account of chemical honding and structure. Ten chapters of the book cover the development of quantum chemistry, the periodic table, ionic and covalent bonding, molecuIm geometry, transition metal and electron-deficient compounds, electronic structure and chemical reaxtions, and structure and honding in crystals. The last three chapters discuss various methods of strncture determination. A short bibliography, a set of 67 problems (which are referred to in appropriate places in the text), a table of fundamental constants, tluswers to ahout hdf of the problems, and an index are appended. While muoh of the hook covem items usually encountered in freshman ohemistry, the broad spectrum of topics, especially the chapters on structure determination, and the level of presentation make the book suitable as supplementary material for a high school or freshman course. The wealth of illustrative material, lucidity of presentation, and reasonable cost will be welcomed by students. The book is ruggedly constructed and lasts through handlings by several people. JOHNR.
