JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS 485 Much of the book describes specific and on the whole useful procedures to be followed by the individual who wishes to improve and develop his creative abilities. Furthermore, the author is very concerned about the effect of com- mon management practices. Re- ward and recognition are extremely important to the creative in- dividual, but he believes (and rightly) that rewarding by promo- tion into the ranks of management results only in stifling the creative person. He urges instead more use of the "Senior Scientist" con- cept. He would also like to see companies develop the "Creative Lodge" idea, a spot where creative employees could go in order to incubate their ideas, in peace and privacy. Finally, the author is concerned with wider ramifications of the central problem: that of permitting creative individuals to function most effectively, for their personal fulfillment and for society at large. He deplores pressures to conform and also many educational pro- cedures, practices which this re- viewer also deplores. In conclusion, the book is worthy of attention by scientists, by man- agement, and by those with social consciences.--DR. AUDRV,¾ F.

Scott's Analysis, as it is known to most analytical chemists, has been a much used reference book since its first edition in 1917. The fifth edition appeared in 1939, and the book has been brought up-to- date in this, the sixth edition. Its text differs significantly from that of the fifth edition and has also been changed by inclusion of new procedures and numerous refer- ences to the original literature. Analytical chemistry has changed greatly in the past twenty years and "wet methods" have been sup- planted by instrumental procedures. These procedures not only improve acuity of the human senses (e.g. spectrophotometers) but permit use of physical measurements not even dreamed of in 1930. Polarography, invented in 1922, became a useful tool only in 1935 after Kolthoff extolled its virtues, and the in- ventor of polarography, Heyrovsky, received the Nobel prize in 1959, more than 35 years after his dis- covery. Since World War II, many analytical procedures applicable to inorganic materials have been added they range from cryoscopy through spectrophotometry (emission fluo- rescence, u.v. and visible), x-ray dif- fraction, mass spectrometry and nuclear magnetic resonance to ac- tivation analysis. Despite this in- crease in available methods and despite the development of auto- matic analyzers which swallow a sample on one end and spit out an analytical report a few minutes later, the inexpensive and precise wet procedures are still needed for a variety of analytical jobs encountered in day-to-day opera- tion of a laboratory. It is indeed a credit to the editor to have avoided excessive em- phasis on the "glamour" methods in this revision but to have re- tained the techniques of "wet" chemistry. This volume is concerned with the assay and detection of individual elements. Each chapter, in addi- tion, includes methods for the analysis of common commercial compounds or sources of the ele- ment. Altogether more than 80 elements are covered. Analyses in-

The text is readable, and methods and sep- arations are described carefully. The s.etup of special trains, etc., are g•ven diagrammatically and carefully labeled. Although the sixth edition follows the pattern and repeats some sec- tions of the fifth edition, it should be a worthwhile addition to chem- ical libraries, in view of its wide scope and great comprehensiveness.-- M. M. RIEGER, WARNER-LAMBERT PHARMACEUTICAL Co. SURFACE ACTIVITY, by J. L. Moil- liet, B. Collie, and W. Black. D. Van Nostrand Co. Inc., Prince- ton, N.J. 1961. 518 pages. Price $15. This is the second edition of a monograph which, since its ap- pearance in 1951, has become one of the standard works in its field. Readers familiar with the first edition will find that the authors have changed the form very little. Nevertheless, they have fitted in a wealth of new material, deleting older items and references that are no longer of prime value, to produce a fresh, up-to-date volume. The book's 15 chapters are grouped into three parts entitled "Physical Chemistry of Surface Active Agents and Interfacial Proc- esses, .... Technical Applications of Synthetic Surface Active Agents" and "Chemical Constitution of Synthetic Surface Active Agents." Except for the last part, some 140 pages,. which is largely descriptive orgamc chemistry, emphasis throughout the book has been placed on the physico-chemical behavior of surfactants. A unifying thread of modern colloid science is care- fully maintained in the technical applications discussions as well as in the chapters dealing with funda- mental physical chemistry. This is indeed well-named as a treatise on Surface Activity since it is the behavior of the materials, rather than the materials themselves or their specific uses, that occupies the limelight. After a brief in- troduction, the authors begin with a discussion of the solution states of surfactants, emphasizing theories of micelie formation and structure, and solubilization. This is followed by chapters on the in- terfacial adsorption of surfactants and on the major groups of inter- facial processes, including wetting, defiocculation, protective colloid ac- tion, emulsification dispersion and foaming. The discussion is well balanced between the formal mathe- matical approach and the descrip- tive or phenomenological approach. In the five chapters on technical applications the various individual processes are grouped on the basis of the dominant colloid chemical effect that is involved. Thus the processes that depend on wetting, emulsification, dispersion of solids and detergency are considered col- lectively and their common features emphasized. A separate chapter is devoted to processes that depend on a variety of other colloidal prop- erties of surfactants. The book is excellently written and the references are well selected. The authors never neglect to guide the reader with their own opinion when controversial or conflictin• literature is cited. These points all contribute to making a good read- able text that will be useful to all interested in surface activity--A.
