JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS 243 The author has selected a repre- sentative group of patents in the fragrance field. Consequently, the book should be especially useful to anyone who wants to inake a quick survey of the recent developments in the fragrance technology covered by patents. No comments are made on the industrial importance of the patents, nor are there any references to the scientific literature. The book is, therefore, only a compilation of selected patents with summaries of inventions and examples taken tom the specifications. A table of contents at the kont lists each patent and serves as a sub- ject index. This book is also indexed by company, inventor, and U.S. Patent number. This arrangement should facilitate the locating of a patent in the book. A similar voluine authored by M. Gutcho was published in 1970 by Noyes Data Corporation under the title, "Chemical Process Review No. 45, Synthetic Perfumery Materials." It is essentially the same in organi- zation and scope as the present vol- ume, but covers an earlier period (1951-1970). A number of patents are included in both volumes. The basis for selecting patents for either volume is not clear to this reader. It would seein that a small supplement would havc sufficed to update "Re- view No. 45," rather than this new volume.--NoRMaN L. GaE•--Givau - dan Corporation. THE PHYSIOLOGY AND PATHOPHYSI- OLOGY OF THE SKIN . Vol. III, Edited by A. Jarrett, Acadeinic Press, New York, 1975, Price $34.50. Voluine I of this series was on the epiderinis and Volume II was on the nerves and blood vessels. This series of books is aimed at bringing to- gether contemporary knowledge and thinking on normal and abnormal skin physiology in a form such that the practicing dermatologist, biolo- gist, and other scientists can relate it to some of the clinical problems each encounters. This volume concerns itself with the dermis and the dendritic cells of the epidermis. The first section, on the dermis, gives an account of the chemistry of collagen and elastic tissues. The physical nature of the dermis in the living skin is dis- cussed in some detail. Diseases af- fecting collagen and elastic tissue are described froin the standpoint of their pathogenesis and pathophysi- ology. There is also a chapter on the comparative physiology of the der- mis and the relationship between its function and physical characteristics in different animals and body sites. Special reference is made to melan- ocytes and its pathology in pigmen- tary disorders of huinan and animal skin. Some of the sections of particular interest to the cosinetic chemist are those on the chemistry and molec- ular biology of collagen the physi- cal nature of the dermis and the elastic tissues in living skin dermaI cell populations and their pathologi- cal responses melanin and melan- ocytes and the biochemistry of pig- ment formation. The chapter on ageing of the der- mis is of special interest. This chap- ter reviews skin thickness and an in- strumental technique of charting it the physical and physiological changes that occur with age the

SAan, Ph.D.- American Cyanamid Go. HANDBOOK OF MOISTURE DETER- MINATIONS AND CONTROL, PRIN- CIPLES, TECHNIQUES, APPLICATIONS, Vol. 2, by A. Pande. Marcel Dekker, Inc., New York, 1975. XV + 318 pages. Price $33.50. This volume constitutes four of 15 chapters (5 through 8), which will appear in four volumes utilizing con- tinuous pagination. The index will appear in volume 4, thus limiting ac- cess to specific items without the availability of the set. This reviewer has not had access to these other vol- umes. The four chapters of this volume are titled "Electrical and Electronic Methods .... Spectroscopic Methods and Techniques .... Nuclear Methods and Techniques " and "Automatic Control of Moisture." All pages are photo-offset from the original typewriter prepared manuscript. There is no attempt to relate to any specific industrial area, but rather, the examples are taken to illustrate the procedure without concern to the material in which the water is present. Each method description is well-written and explains the princi- ples and procedures without exces- sive detail. For those who want a basic understanding of the multitude of instrumental techniques available, this is very readable and informative. Indeed, solutions to unique indi- vidual problems may become obvi- ous to the reader. Unfortunately, few references after 1965 are to primary sources, but are rather to books or reviews after this date. The extensive refer- ences are mostly earlier than 1965. As stated, this book is an excellent source for any scientist who desires to obtain a good background in all principles of nonchemical water de- termination. It is especially com- mended to anyone having a problem in finding a suitable assay for a sys- tem not amenable to routine pro- cedures.-Jo•N H.

Chapman & Hall, London and John Wiley & Sons, New York. 381 pages. Price $24.00. If this book is not the Bible of the perfume industry, it is at ]east one of its important chapters. This 8th edition of "Poucher's" is a com- plete revision of the earlier perfum- er's classic. It is in consonance with the modern world of the cosmetic. Many new materials have been add- ed, and older obsolete materials have been deleted. A system of cross-referencing links the accepted chemical nomenclature to the terms of present usage. A considerable number of formu- las are presented for floral scents and bouquets. Processes are de- scribed. A few illustrations are pre- sented. All in all, this new edition is rec- ommended as a useful up-to-date reference book.--CI-mSTEa J. DE ZEro --Valjean Corporation, Florida.
