Book Reviews COMPREHENSIVE BIOCHEMISTRY, VOL. 26, PART C: EXTRACELLULAR AND Sue- PORTING STRUCTURES (Continued), Edited by Marcel Florkin and Elmer H. Stotz. Elsevier Publishing Co., Amsterdam, Netherlands, 1971. 898 pages, indexed. The volume is characterized by clear and precise writing. The reader, whatever discipline he ascribed to in the natural sciences, can well appreciate the manner in which the materials are presented. The chapters on "Chitinous Struc- tures" and "Resilin" are presented, respectively, by Charles Jeuniaux and S. O. Andersen, in a very compre- hensive style. Less comprehensive, but nevertheless interesting and in- formative, is the manner in which Carl Franzblau writes of "ElaNtin." The information on elaNtin, however, would have been more apropos in Part B of this volume. There, with chapters on other fibrous proteins, it would have made Part B more comprehensive. As it is, one is aware of an interruption between Chapters IX and X and the rest of Part C. Margaret Jope's chapter, "Constit- uents of Brachiopod Shells," and John Eastoe's "Dental Enamel" are 591 a treasure for those seeking to fa- miliarize themselves with these sub- jects. Their presentations are com- plete and for those interested in further detail, the writers give ample references. Unfortunately, the same cannot be said of Rend Defretin's "The Tubes of Polychaete Annelids." In many instances the lack of refer- ences prevents one from further pur- suing a point. Apart from the disadvantages men- tioned, the volume is well worth its acquisition.--AscmL CARRmLo--The Gillette Company Research Institute PROBLEME DER LOKALEN STEROIDBE- HANDLUNG, by Wolfgang Raab.

This monograph is an unmistak- able sign of a major difference be- tween cosmetics in Europe and in America. The fact that "Problems of Local Corticosteroid Treatment" should be the title of the first vol- ume of a series of books devoted to cosmetics is a clear indication that there is a much larger interface be- tween dermatological and cosmetic
