JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS 357 1961. Naturally the first com- parison is the previous edition. Essentially the only changes are, as listed in thepreface, pages 269-273 and 335-336, with a slight corre- sponding change in the chapter ref- erences. Otherwise the pagination is identical with the earlier edition, and no changes could be detected. Hence, except for the passages cited as changed, this is still in its entirety the 1961 book with no attempt to update it otherwise. There is one difference, however. The index has been greatly ex- panded-almost doubled--so that it provides an excellent access into the book. In addition the complete author reference index is retained. The book is developed under eight chapter headings: The Physics of Surfaces, Electrostatic Phenomena, Electrokinetic Phenomena, Adsorp- tion at Liquid Interfaces, Properties of Monolayers, Reactions at Liquid Surfaces, Mass Transfer across In- terfaces, and Disperse Systems and Adhesion. The subject matter is very lucidly developed with extensive use of tables and figures, so that the whole is very readable. At the end of each chapter is an extensive list of references, in the order of a hundred each, which have been cited in the course of that chapter. The reader thus receives the impression that each chapter represents a complete review and that the bibliography represents all pertinent papers. This is unfortunately not quite the fact. The authors have de- veloped a complete exposition draw- ing heavily on the European publi- cations and almost completely ig- noring work from this side. Now admittedly publications fr3m the U.S. have not been as prolific as the importance of this field would justify. However, few receive even the courtesy of a citation. In this regard the reviewer feels that some companion book for balance needs citing, but there is no such available! However, another recent English publication "Gas/ Liquid and Liquid/Liquid Inter- faces--A Bibliography" (2 vols.), by D. W. Stephens, with an intro- duction by J. T. Davies, published June, 1962, by Joseph Crosfield & S,3ns, Ltd., Bank Quay, Warrington Lane, Gr. Britain, provides a wealth of additional references, without regard to national origin. Nevertheless, this is an excellent book, one that is a must for colloid chemists. The average cosmetic formularive chemist is likely though, to consider it somewhat too theoret- ical to be one of his standard texts. However, judicous selected readings cannot but enhance his under- standing for many of his problems, and it is therefore one of the books that should be available to him.-- JoH• H.

A distinguished group of con- tributing editors have condensed an enormous amount of chemical information into the 1300 pages of this volume. Organic name re- actions, thermodynamics, rotational energy levels of molecules, the law of ph.ysics, structures and names of organic and inorganic compounds, and thousands of other subjects have been combined to create this volume. Most headings are followed by brief explanations although many entries in this encyclopedia cover more than one page and are sound treatments of certain topics of chem- istry. Particularly noteworthy is the long entry on organic nomenclature. On the other hand, some less im-

358 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS portant aspects of inorganic chemis- try have been over-emphasized. This reviewer feels, for example that too many compounds of phos- phorus receive individual listings on pages 896-902. It appears that the authors made a very careful attempt to include all types of reactions even oc- casionally obscure references. Al- though their efforts in this area must receive E for excellence, oc- casional inconsistencies occur: For example, the Millon test for pro- teins •s described under Millon Reagent but not under the heading of Protein Tests. Six different tests are listed as Protein Tests. Neither biuret nor ninhydrin is mentioned, but the Arnold test is included. This test is specific for the presence of mercaptan groups, nonspecific for proteins, and curiously enough is elsewhere described as the Howera- Bermejo test. A fault of this type does not lower the value of this vol- ume as a desk reference for the scientifically trained person. This volume is not designed for use by secretaries or by people who do not possess a fairly sound foundation in the physical sciences. On the •ther hand, this volume will be particu- larly welcome to those of us whose memories have occasional lapses. The structural formulas, equations, and concise discussions help to make this encyclopedia a one- volume reference library. The volume also includes a glos- sary of German, Spanish, French and Russian chemical terms and their translation into English. It is unlikely that this feature will be much used by chemists since most of the terms listed are' highly specific and, therefore, are "identical" in all languages. Certainly any chem- ist will recognize triazine in any of the following languages: French- triazine German-Triazin Spanish- triazina Russian-TP_,A:3,Ht4. The type is very legible, and the paper appears to be of good quality. In summary, the creators of this volume have done a very creditable job. Their efforts undoubtedly will be rewarded by wide acceptance of this encyclopedia as the abridged Webster of Chemistry.--M. M. RIEOEP., Warner-Lambert.
