BOOK REVIEWS 409 of definitions dealing with the many facets of color and coloring. It is interesting to note that nylon is not a trade mark name. The addenda are also useful in this compilation. A good book, not overpriced and generally useful.--M. G. D•.- •rAVARRE. DICTIONARY OF MICROBIOLOGY, by M. B. Jacobs, M. Gerstein and W. G. Walter. D. Van Nostrand Co., Inc., Princeton, N.J. 1957. 276 pages, size 6 X 9 inches, illus- trated. Price $6.75. Over five thousand entries cover every phase of microbiology. Many unusual words are defined culture media are described, methods and apparatus are mentioned. The material appears complete. The definitions are concise. The book fills a need and will find a place on the reference shelves of many cosmetic libraries.-- M. G. r)ENAvARRE. DAS HAAR, by Anton Hopfl. Bay- erischen Schutbuch Verlag, Munich 19, Germany. 1955. 76 pages, size 6 X 8, illustrated (in German). A compilation of over 100 illustra- tions of various facets of the micros- copy of hair. Covered are: skin, hair growth, hair waving and dyeing and a very brief chapter of three pages on nails. The text describes the illustra- tions. An excellent reference book. --M. G. •ENAvARRE. COMMERCIAL WAxr. s, edited by H. Bennett. Chemical Publishing Co., Inc., New York 10, N.Y. 1956. 699 pages, size 51/g X 81/g inches, illustrated and indexed. Price $15. A revision of an earlier edition, bringing up to date the data covered previously. A hundred thirteen pages are devoted to petroleum and hydro- carbon waxes. The section appears to be well done. The vegetable waxes include the main commercial ones. The material is not intended to be as extensive and thorough as Warth's "Chemistry and Technology of Waxes," but it is adequate. A few pages are devoted to fatty acids, which seem out of place since they are not waxes in any sense. The data on fatty acids can be misleading since there are so many types within one source of supply and there are quite a few sources. The same comments apply to fatty acid esters described. In addition it is unfortunate only one brand of these esters is described in detail when others are widely used. --M. G. DENAVARRE.
