80 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS various cosmetic materials, along with formulations quoted from the works of others. The volume is completed with a thumbnail sketch of the activities and principal prod- ucts of some of the better-known European perfumery houses. Cerbelaud's original work in Vol- ume II consists of a discussion of toilet creams, rouge, lipstick, face powder, shampoo, and related prod- ucts. In Volume III, the original mate- rial consisting of a discussion of formulation of additional creams, dentifrices, cologne and toilet water, and hair dyes, the latter being quite a large section. In fact, the 1936 material consists of over 1000 pages in itself. Mr. V$lon completes the book with chapters on make-up, shaving creams, shampoo and scalp products, sunscreens, and nail pol- ish. There are some typographical errors, such as using PD&C for FD&C, and Ohlson for Ohlsson. There are a few scattered errors in the original text. But in an effort of this magnitude, it would be im- possible not to have minor faults. There is no doubt that the con- tributions of Velon, Boutder, Sidi, and Bornand have embellished Cer- belaud's work. The earlier material has been improved upon, yet much of it is as valuable today as when volume III was revised in 1936 when this reviewer had the privilege to correspond with the author on the revision of that day. One is somewhat confused by the .arrangement of Cerbelaud's work and no one will admit the difficulties of properly organizing cosmetic data more quickly than the re- viewer. Perhaps the trouble is with the versatility of the author himself. A volume on perfumery, another on creams, and lotions end- ing with a third volume on make-up, would have done the trick admi- rably. While the revised material does bring the work up to date, one gets the feeling that the large portion of the task went to Mr. Velon. So to him must .go the criticism and praise in propomon. Author Velon depended much on T.G.A. data which flatters us, but should he have not used more Euro- pean material? The literature of the cosmetic industry is heavily quoted. More original formulas should have appeared. Some pat- ents are referred to, but most are ig- nored, whether of U.S. or European origin. Some literature is quoted, but much valuable material is by- passed. The new material is not in- dexed. Publishers of books on cosmetic subjects are hesitant to destroy the type of a successful book. Instead they prefer to make additions at the end of the old manuscript. This leads to large, bulky, and expensive books, as in the case of the present work which in Paris is worth about $55.00. Some of the old material could be deleted and thus make the volumes smaller. Yet no one will underestimate the additional value of the 610 pages of newly contributed material by the several authors, particularly by Mr. Velon, who brings more cosmetic science into Cerbelaud's work than the original author would have thought possible.--M.
