148 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS plan for the material presented. They have attempted to use com- mon names of chemicals, then refer the reader to the properly named compound. Unfortunately, there is still a bit of confusion here, although there is a great improvement in this edition as compared to the former one. Chemical/lbstracts is the guide for references and nomenclature. The usefulness of a set of refer- ences can be appreciated only by those who have had occasion to use them. Those who are acquainted with earlier editions, and all the others who do organic research-- laboratory or/and library--will need this greatly expanded work. You couldn't do better than to have a set in your library.--M. G. DEN^v^RRE. FORMULARY Or PERFUMERY AND Or COSMEXOLOCY, by R. M. Gatte- fosse, translated by A.R.I.C. Leo- nard Hill, Ltd., London, N.W. 1, England, 1952. 250 pages, $1/2 X 81/2 inches, indexed. Price 17s.6d. More than half of the pages are devoted to perfumery the balance covers the compounding of cosmet- ics. The book is replete with many for- mulas for perfumes and cosmetics. The perfume formulas appear to use only standard materials whereas the cosmetic formulas include numerous specialties produced mostly by the author's affiliated company. This is considered bad taste in the U.S. The author has considerable skill as a perfumer but this reviewer doesn't think he had the same skill in cosmetic formulation. Thus a formula for a "Very Fatty Milk" consists of "petroleum oil 35 parts, polyol octadecyl derivative 5 parts, and water 60 parts." What is the polyol octadecyl derivative? An es- ter ? An ether ? Which polyol? How does it emulsify? Is it self-emulsi- fying? Or is it an acid type emulsi, tier? Other ingredient descriptions are "Fatty acid monoester, .... Gly- col, .... Hydrophilic oil, .... Hexose," and "Methylcellulose gel" to name a few. What are these materials? How can the cosmetic chemist at- tempt to make these formulas on such sketchy material descriptions. Worse, procedures for manufacture are too often completely omitted. This reviewer deplores the publi- cation of such poor material, partic- ularly when it could be vastly im- proved by the author. It is ad- mitted that a book often suffers in translation. So, some of these er- rors could creep in that way, but not so many. If you want a mediocre formu- lary, this will fill the need.--M. G. DENAVARRE. APPLIED MYCOLOGYAND BACTERIOL- OC¾, by L. D. Galloway and R. Burgess. Leonard Hill, Ltd., Lon- don N.W. 1, England, 1953. 184 pages, $1/2 X 81/2 inches, illustrated and indexed. Price 12s. This is the third edition of a work first published before World War II. In the first edition foreword, the authors correctly state that the problem in writing this condensed manual was not what to include but what to leave out. Certainly, bacteriologists and my- cologists will consider thi• book as sketchy. But it is not intended for them but for the "works chemist" faced with bacteriological problems. Five industries, food, fermentation, textile, hygiene, and agriculture, are allotted a chapter each. One chap- ter "miscellaneous" covers another ten applications, but drugs and cos- metics are not included. The few pictures present are well done. The authors list many bacterio-

BOOK REVIEWS 149 logical procedures in brief. The microtechnique so often used for quick results is not mentioned. The coagulase test so important in food work is not included. Many well-known tests and differ- ential media are discussed but the authors fail to indicate what one can and should expect in a positive test. Thus under "Bile Salt Lactose (MacConkey) Broth," on page 55 states that it is used "for indicating the presence of Bact. coli" (authors abb.), but nothing is said about just how this media indicates the pres- ence of the organism. Such data are very vital to the people for whom the book is intended, because bacte- riologists know what to look for. It is a difficult task to condense so large a subject into so small a book. The most superficial treatment must be given and that is exactly what has happened. The idea behind the writing is good, needed, and desir- able. But the result ha• a nebulous usefulness. Adding to the problem is the practical discussion which takes up about half of the book. Either the theory or the practical applications should be eliminated and the remaining subject should be expanded.--M. G. DENAVARRE. QUANTiTATiVE PHARMACEUTICAL CI•.M•STRV, by Glen L. Jenkins, John E. Christian, and George P. Hager. McGraw-Hill Book Co., New York 36, N.Y., 1953. 534 pages, 51/2 X 8 inches, illustrated and indexed. Price $6.50. To begin with, the book is well priced. The choice of authors is the best. Obviously intended as a text, it is of good school size. The selec- tion of text is ideal for pharmacy students and commercial drug ana- lysts. The material is intended to include latest products covered by the U.S.P. XIV and N.F. IX. Under general remarks there are useful descriptions of logarithms and their uses. A little unusual in a "quant" text is the description of gasometric methods--very useful. Among newer procedures de- scribed are the potentiometric Karl Fischer method for water, spectro- photometry, fluorophotometry and electroanalysis. Polarographic meth- ods, which are not official, are not included. One can find little fault with the material presented. As an analyst, immediately after graduation this reviewer found one common failing in most school texts, namely, the lack of methods for mixtures of offi- cial materials. The present text is no exception. Simple mixtures like those of aspirin, caffeine, and phen- acetin are enough to stop a fledgling. Resolutions of mixtures of lanolin, beeswax, and petrolatum require considerable skill. A few such as these, included with the simple pro- cedures, would be of inestimable help to student and commercial ana- lyst alike. The descriptions under the var- ious methods are clear and valuable. As a supplement to official compen- dia, this text will continue to fill the void it has in previous editions. This reviewer recommends'it as a must for all analysts in the drug and cosmetic industries.--M. G. DENA- VARRE. INSTRUMENTAL ANALVS•S, by John H. Harley and Stephen E. Wiber- ley. John Wiley & Sons, Inc., New York. 1954. 440 pages, in- dexed and illustrated, 6 by 91/4 inches. Price $6.50. This book is intended as a text for use in a course in instrumental anal- ysis. It is a very good work for this purpose, and for other purposes also.
