832 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS This text is recommended as a gen- eral review and reference text for those interested in updating their knowledge of analytical chemistry and analytical pharmaceutical chem- istry.--P^UL TnAu--CIBA Pharma- ceutical Company. OIL, DETERGENTS AND MAINTENANCE SPECIALTIES. VOLUME I: MATE- RIALS AND PROCESSES, edited by Ben- jamin Levitt. Chemical Publishing .Company, Inc., New York. 1967. 280 pages indexed. Price $13.75. This is the first of two volumes deal- ing with all aspects of fats and oils in- cluding raw materials, manufacturing processes, test methods and applica- tions. This volume deals primarily with materials and manufacturing processes, although many formula- tions are included. Volume II will deal with additional applications. After a brief introduction, this book is divided into eight chapters: ani- mal fats and oils vegetable fats and oils fatty acids and alcohols sur- factants production of fats and oils soap manufacture synthetic deter- gents and analysis of oils and deter- gents. Since all of the topics covered in these chapters have already been the subjects of full length volumes, the author could include only a small frac- tion of the information available on each topic. Unfortunately very few references are listed, and many of the classic texts on oils and fatty acids are not mentioned at all. Yet, there is much useful informa- tion in this book, and it should be of value to individuals who are not di- rectly involved with fats, oils and de- tergents but would like a handy refer- ence work on these subjects.--T. KAUFM^N--Drew Chemical Corp. MATHEMATICS AND STATISTICS FOR TECnNOLOGISTS, by H. G. Cuming and C. J. Anson. Chemical Publish- ing Company, Inc., New York, N.Y. 1967. 400 Pages, indexed and illus- trated. Price $12.50. This is a most unusual and valuable book for the industrial scientist, but it is not entirely what its title implies. A more appropriate name, which would describe over 75% of the con- tents (and, in my opinion, all of the more valuable material) might be, "A Concise Review of College Mathe- matics for Teehnologists." The value of the book lies in the fact that most of the material (351 of the 400 pages) comprises a lucid and suednet presentation of nearly every important topic in college mathe- matics normally encountered by the undergraduate chemist or engineer, but aimed specifically toward the needs of the adult professional who may wish a relatively painless refresh- er course. I believe that any such person who has studied the topics cov- ered, even several decades ago, will find the book easy to study as well as an excellent reference work. Despite the brevity of most of the topics, all are treated with clarity and vigor, al- though with no attempt to develop

JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS 833 complete proofs in every case. The subjects covered range from elemen- tary algebra through analytic geome- try, trigonometry, intermediate alge- bra, differential and integral calculus with applications, and differential equations. Each topic includes a good supply of examples, and each chapter ends with a group of problems for practice, with answers given at the back of the book. There are a few short chapters on elementary statistics, comprising a total of 114 pages, including an intro- ductory section and short chapters on probability, frequency distributions, control charts, sampling, significance tests, analysis of variance and simple linear regression. In sharp contrast to the above material, these give the impression of having been included as an afterthought. They are brief, in- complete and quite inexact. The adult reader would do better to ignore these chapters and, after covering the mathematical material, to consult some more expert text on applied statistics, such as Mandel's "The Statistical Analysis of Experimental Data" (Interscience, 1954). A regrettable omission is the lack of a chapter on matrix algebra, a most important topic in modern applied statistics. Also, there is no material on solid analytical geometry. In spite of these omissions and the short- comings of the statistical section, however, this text is most highly rec- ommended to the audience for which it is intended.--W. M. WooreNo-- Carter-Wallace, Inc. RESEARCH IN SURFACE FORCES. VoL. 2. Edited by B. V. Deryagin. Pp. viii X 320. 1966. Consultants Bureau, New York. $27.50. This is a compilation of the papers presented at the Second Conference on Surface Forces which was spon- sored by the Institute of Physical Chemistry of the Academy of Sciences of the USSR. Volume 1 contains the papers presented at the First Confer- ence on Surface Forces which was held in March of 1960 and which celebrated the 25th anniversary of the Laboratory of Surface Phenomena of the Institute of Physical Chemistry. Academician B. V. Deryagin, in addition to being the editor, is the author of many of the papers. His lead article points out that the empha- sis in Volume 2 is on the three dimen- sional aspects of surface forces. The volume is divided into five sec- tions of about eight papers each: "Theoretical Problems in Sur- face Phenomena," "Electrosurface Forces," "Experimental Studies of the Properties of Thin Films," "Sur- face Phenomena in Dispersed and Porous Systems," and "Surface Phe- nomena in Adhesion and Friction." Over half of the papers are from Deryagin's laboratory at the Institute of Physical Chemistry: however, approximately ten additional labora- tories in the USSR are represented. A wide variety of problems in both fundamental and applied Surface Chemistry formed the subjects of the papers in this volume. This reviewer
