JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS 493 SPICES, by John W. Parry. Chemi- cal Publishing Co., Inc., New York 10, N.Y. 1962. 226 pages, illus- trated and indexed. Price $8.75. About 185 pages of this interest- ing book are devoted to the anatomy of plants used as spices. The balance of the work considers the chemical composition of the spices. The first part of the book is ar- ranged by botanical morphology and histology. The second portion is arranged alphabetically starting with allspice and ending with tur- ineric. One does wonder how dill, garlic, onion, parsley, peppermint and spearmint, to name a few flavoring materials, are considered as spices. The book is a thumbnail sketch for the busy but interested reader on the general subject of spices and natural flavoring products.--M. G. I3 E •-N, • ' PRINCIPLES OF ORGANIC CHEM- ISTRY, by T. A. Geissman. W.H. Freeman and Co., San Francisco 4, Calif. 635 pages, illustrated and indexed. Price $7.00. The author concentrates on prin- ciples eliminating much often in- cluded general information. The subject is presented in terms of chemical "groups" rather than of compound classes. Thus the hy- droxyl group is considered in place of alcohols. Typical of textbooks, short exercises are found at the end of each chapter. As a result, the author feels he has produced a text adequate for a one year course in organic chemistry. The author uses a number of sketches which seem so popular these days in teaching chemistry. Some explain the text well but others would be confusing. The book is well written and the subject is clearly presented. It is a good refresher for those out of school for awhile.--M. G. DEN. ORGANIC PEROXIDES, by E.G. E. Hawkins. D. Van Nostrand, Inc., Princeton, N.J. 1961. 434 pages, indexed. Price $12.50. There are at least two good books on hydrogen peroxide available to chemists. Rieche's ALKYLPER- OXVDE UND OZONmE was pub- lished in 1931 and the Tobolsky and Mesrobian, ORGANIC PER- OXIDES, appeared in 1954. There are an increasing number of articles on organic peroxides ap- pearing in scientific and trade }ournals. Hence the publication of this work fills a need. In twelve chapters the author summarizes all the work up to the present day including reactions of peroxides, kinetics, analysis, appli- cations and autoxidation Although "the method of classification used may not be ideal," it must suffice until a better one is worked out. This book is for advanced stu- dents of the subject--M G. DEN.
