BOOK REVIEWS 375 pounds of phosphorus, the present author prefers to develop a "philos- ophy for the nascent discipline of phosphorus chemistry." It can be reasoned that the body of recognized chemical science is too great and specialization is the answer. Just as silicon, sulfur, nitrogen and car- bon compounds have necessarily been dealt with separately, so must phosphorus be considered. Perhaps the most outstanding feature of this volume is the author's self-assurance in discussing the chemistry of the compounds of phosphorus. This may stem from his industrial background, on which he depends to fill in the voids often found in texts authored by academi- cians. Thirteen chapters cover the "chemistry" of the phosphorus com- pounds. (A subsequent volume will discuss technology and appli- cations.) Of particular interest to this industry are the chapters treat- ing the polymeric phosphates. Here one notices the author's strong convictions regarding structure. He backs up his reasoning with a well documented study. The book is well and convincingly written. One awaits the second volume to complete the subject. Both author and employer Mon- santo are to be complimented for this book.--M. G. DENAV^RRE. ABREGE DE COSMETOLOGIE PRA- TIQUE, by Paul Larrieu. Editions Varia, Paris VI, France. 1957. 72 pages, size 7 X 101/2 inches. Price 820 francs. The title word "Cosmetologie," the use of which is still discussed by cosmetic chemists in this country, has been adopted definitively in Europe as meaning the "science of beautifying," involving interrela- tions with biology and dermatology. The book itself is written spe- cially for pharmacists to give them a basic knowledge which they un- doubtedly should have. The first chapter describes the skin, its composition, its role and how it is affected by internal and external conditions, normal and abnormal, naturally occurring or artifically produced. The second chapter lists alpha- betically and describes various raw materials, including vitamins, es- sential oils, vegetable and animal extracts, used in European cos- metics, their functions, their limi- tations. The third chapter is a rather con- densed formulary explaining quali- tatively the composition of cos- metics and giving a few quantitative examples. A description of types of skins, systems of classification and sug- gested treatments form the fourth and last chapter which is followed by a bibliographical list of references from French publications. This book is exactly what it sets out to be: an intr.oduct.ory presenta- tion to cosmetic science which should give a taste, and a good one, of its substance and methodology to pharmacists who may not know it.-- P•ERRE L.

In the chapters on specific meth- ods, more extraction and chromato- graphic procedures are included. Newer methods have been added and old methods brought up to date. More specific applications of meth- ods have been included. This volume of selected methods remains an outstanding contribution to analytical chemistry and a valua- ble addition to any analyst's library. --S. R.
