906 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS finally a brief treatment of the cap- sular antigens. The final chapter on Calcified Shells by Wilbur and Simkiss com- pares particularly the biochemical development of avian eggshells and molluscan shells. Considerations of the organic matrix, inorganic com- position, crystal structure, and elec- tron microscopy combine to make a unique treatment of the subject. Volume 26B continues with four chapters discussing collagen, car- tilage, silk, and keratin. The chapter "The Nature of Collagen" by Allen J. Bailey, Cambridge (115 pp., 403 refs.), is a thorough digest of a com- plex subject, ranging from the bio- logical to chemical aspects, including short sections on experimental lathy- rism, immunochemistry of collagen, and aging. The various theories of collagen structure are developed and critically examined. "Cartilage" by A. J. Barrett (40 pp., 346 refs.) provides a succinct and factual review of the subject, pro- viding particularly information on the protein-polysaccharide complexes of cartilage, structure and properties of the matrix, and biosynthesis of the matrix components. The third chapter by F. Lucas and K. M. Rudall on Extracellular Fibrous Proteins treats the general subject of silks, their production, amino acid composition, structure, and conforma- tion. In the chapter by K. M. Rudall en- titled "Intracellular Fibrous Proteins and the Keratins" (31 pp., 73 refs.), the general subject of keratins and keratinization is reviewed. Of par- ticular interest is the role of Vitamin A in keratinization, the cellular organization responsible, and the proteins of the epidermis.--BERNARD !Dso•--Hoffman-LaRoche, Inc.
