40 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS Analytical Chemistry is reviewed under the classical inorganic/organic headings. In this field the most notable features are the expanding use of instrumental techniques and of automation, particularly in the control of industrial products, and the prominence of the several forms of chromato- graphy. Finally two reports deal respectively with the crystallography of in- organic and organometallic structures and of organic structures. Comprehensive author and subject indexes conclude this excellent little volume which is an essential reference book for every chemist who wishes to keep abreast of new developments. R.P. REEVES. SCIENCE AND THE SKIN. A. Jarrett. Pp. xv + 167 + Ill. (1964.) The English Universities Press, London. Paperback: 12s. 6d. boards: 21s. It is a special pleasure to review a book written by a fellow-member of the Society and the more so when the author is a British dermatologist who is also a keen research investigator. This is not a treatise, but a fairly simple exposition aimed at those who work on the fringes of the skin field. Part One presents the elementary facts of morphology and physiology, which are developed in Part Two as an excursion through present-day research this is naturally concerned to a large extent with frankly pathological conditions but nevertheless sheds a good deal of light on the problems encountered in cosmetic science. Jarrett does not draw a hard and fast distinction between the proper sphere of cosmetics and the realm of the dermatologist, though one acquires the feeling that he might not like to see too much transgression into clinical problems. His plea for the evaluation of protective creams and the like by dermatologists in collaboration with cosmetic chemists, is thoroughly commendable. An injunction might well have been added to stress the need for a rigidly critical approach to the setting-up, conduct and analysis of such clinical trials. The text, by avoiding obscure terminology, is unusually readable however, the scientific reader may encounter the difficulty of subsequently meeting the conventional terms without recognizing their significance. For example, Jarrett distinguishes between the sweat glands and the apocrine gland. He does not generally employ the customary designation of the eccrine gland as the source of sweat, and rather confuses the issue by occasional reference to "apocrine sweat glands." In a small volume like this, abbreviation to the point of serious inaccuracy might have been

BOOK REVIEWS 41 anticipated but there is practically no sign of this. In the section dealing with antiperspirant and deodorant action, for example, it would have been easy just to give a brief resumg of the traditional half-truths, but the author's intellectual honesty is even here readily apparent. Cosmetic chemists seeking an introduction to the physiological background of their pursuits will find a great deal to interest them. Nowadays they need to be seriously concerned with potential side-effects and Jarrett demonstrates the correct perspective in relation to irritation, sensitization and carcino- genicity. We could find no reference to dandruff anywhere, which seemed a pity, but obviously Jarrett could not deal with every aspect of dermatology. Perhaps one day he will see fit to compile a larger and more embracing volume with the same type of enquiring approach in the meanwhile, the present one will certainly help to fill the gaps in many readers' understand- ing of the skin and its behaviour. N.J. VAN ABBE. ELSEVIER LEXICA 4: LEXICON OF PRESSURIZED PACKAGING (AEROSOLS). Compiled by A. Herzka. Pp. x + 159 + Ill. (19134). Elsevier Publishing Company, Amsterdam/London/New York. 70s. It is perhaps not too widely known that Elsevier publish a series of dictionaries each restricted to a distinct scientific field. These are intended to supply to technical interpreters and translators a reliable and comprehensive glossary of terms within a particular discipline or technology and to assist the worker seeking to abstract the essential features of a highly specialised publication in an alien tongue. Elsevier select for such Lexicons those languages in which a significant volume of relevant literature exists. The general editor, himself a former chief interpreter to the United Nations Organisation, usually entrusts the preparation to an acknowledged expert in the appropriate field, with assistance from similar authorities in those other countries in whose tongues equivalent terms are desired. The latest "pocket-book" in this series is devoted to the very new realm of aerosol technology. There are two obvious linguistic consequences of the remarkable development of the pressurized packaging industry. Semantic problems have arisen from the extended use of existing terms and the undisciplined coining of new ones, whilst the preponderance of specialist publications in the English language directly results from the pioneering roles of the U.S.A. and, subsequently, the United Kingdom.
