66 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS deed a well-coined name for those times. The reading is most fas- cinating. Chapter 12 (page 294) reviews the progress in scents and flavors through that period. Volume V reviews the "decade of new products" during the period 1930-1939. Perfumes and cosmet- ics comprise Chapter 19 (page 282). Ruzicka's work on musks is men- tioned. The work of men like Gold- schmidt, Evans and McDonough, Max Factor, Burton T. Bush, Un- gerer, Kleber, to name a few, is dis- cussed in this roundup of the industry. Volume VI is devoted exclusively to the company histories of over two hundred companies. Included is the earliest origin of the company, its affiliations, subsidiaries, mergers, and present officials. From this industry histories of the following companies are factually recorded: Colgate, C. E. Ising Corp., P&G, M. M. & R., Los Angeles Soap Co., van Ameringen-Haebler, Verona, Van Dyk and Co., William R. War- ner and Co., and Sterling Drug Com- pany. This reviewer saw no misspelled words. The data that could be checked seemed correct. Exten- sive appendices and tabulations ap- pear in the first five volumes. Price of chemicals, tariffs for various pe- riods, and hundreds of other useful data are included. Both du Pont and Goodyear in- troduced sorbitol a couple of years before Atlas introduced it in 1936, a fact author Haynes did not record. A number of convictions emerge from reading this monumental ef- fort. First, that this is a land of opportunity, a fact recognized by the nationals of many countries who had a hand in creating its great chemical industry. Second, that many of the businesses were on or nearly "on the rocks" but stub- born sticktoitiveness brought them through. (Some of them are not small names either.) Third, fail- ure once or twice did not stop men from trying again. Fourth, that nowhere more than here is it true that "from acorns, great oaks grow." Fifth, the U.S. chemical industry has often broken a strangle hold on some natural or synthetic material, bringing the price down precipi- tously as in the case of ionones, men- thol and the synthetic musks, for example. Sixth, that obstacles, depressions, government control, fights for survival, always acted as industry stimulants. Seventh, that the future of the industry is brighter than ever. Some may argue that additional companies should have been listed in Volume VI. It is hard to draw a line and yet one must be drawn somewhere or the listing would be practically endless. Historically, this is a must for every chemical library. Individual volumes may be had if one does not want the set although there is a con- siderable saving in buying the set. It is hoped that author Haynes can complete a seventh volume cov- ering the decade or more after 1939. Haynes has succeeded in his goal. The entire chemical industry •s thereby forever beholden to him. It has been greatly enriched by this mammoth history.--M. G. DE- NAVARRE. IoN EXCHANGE RESINS IN MEDI- CINE AND BIOLOGICAL RESEARCH.

BOOK REVIEWS 67 Nov. 14 and 15, 1952. It covers a very extensive field and contains a wealth of information. The con- ference was arranged by Doctors H. Sobotka and H. P. Gregor. The paper by P. N. Craig deals with the synthesis of ion exchange resins and considers the relation- ship between the chemical structure and the performance of the several types. The several physico-chem- ical aspects of the reactions involved are considered in the contributions by M. Ezrin and H. G. Cassidy, H. P. Gregor and M. Frederick, A. W. Davidson and W. J. Argersinger, Jr., and B. A. Soldado. There are chapters on cation and anion ex- change processes (by J. I. Bregman and S. Peterson, respectively), also a chapter on non-ionic separations (by R. M. Wheaton and W. C. Bau- man). A special position is occupied by a discussion of ion exchange mem- branes (K. Soilder). The biological and therapeutic application of ion exchange resins is reviewed in several chapters dealing with: separation of blocheroically important sub- stances (W. E. Cobh), purification of antibodies by means of antigens linked to ion exchange resins (H. C. Isliker), selection of cation exchange resins for therapeutic use (A. E. Heming and T. L. Flanagan), sodium removal by cation exchange resins (E. W. McChesney, F. C. Nachod and M. L. Tainter), clinical expe- rience with mixtures of anion and cation exchange resins (K. G. Kohl- staedt, B. L. Martz, R. S. Griffith, and O. M. Helmer), changes in fecal and serum constituents (T. S. Dan- owski and L. Greenman), the role of the gastrointestinal tract in the pre- vention of sodium depletion by cation exchange resins (K. Emerson, Jr., S. S. Kahn, and D. Jenkins), electrolyte and water movement across the in- testinal wall (M. B. Visscher), lab- oratory data and clinical use of cation exchange resins (M. F. Levitt), and ion exchange resins as a diagnostic tool (H. L. Segal). The treatment of the different subjects fully satisfies the high standards which one has come to associate with the conferences of The New York Academy of Sci- ences.--E. G. KLAR.

Editions Opera, Paris 9, France. 1954. 729 pages (including advertising) illus- trated and indexed. Price 5200 francs. Written by three well-known French cosmetic chemists, this vol- ume truly rounds out the earlier three volumes. Each author con- tributes material of a high caliber that is a definite contribution to the cosmetic science. Ren• Colson contributes the first seven chapters which consist of a classification of surfactants accord- ing to 21 groups. Each class is then described in detail and examples of American, French, German, Bel- g!an, and British manufacture are g•ven. The French products are stressed as they should be. An unusual arrangement includes formulations of a variety of cosmetic products that can be made from them. Both ingredient and product pat- ents are discussed throughout. The second part consists of a col- lection of analytical methods appli- cable to cosmetics, written by Pierre Velon. This author has made nu- merous contributions, on the same subject, to cosmetic literature. After an introduction to standard, modified and new methods, the author discusses many of the prin- cipal cosmetic materials. In doing so, physical and chemical properties, adulteration, and usefulness are covered. Where does one draw the line in
