BOOK REVIEWS SPECIFIC METHODS OF ANALYSIS, consulting editor Samuel E. Q. Ashley, pages 995-1118, Volume 53, Annals of the New York Academy of Sciences, New York, N.Y. 1951. Price $2.50. A cardboard covered reprint of portions of the Academy Annals deals with specific methods of anal- ysis, but they are all out of the present scope of the toilet goods in- dustry. It is a typical Academy publication, well printed and author- itative.--M. G. t)EN. P^P^IN, Consulting Editor M. L. Tainter pages 143-296, Volume 54, Annals of the New York Academy of Sciences, New York, N.Y. 1951. Price $3.00. Ten chapters or contributions with a foreword by M. L. Tainter and O. H. Buchanan constitute this typical Academy publication. It is a study of the proteolytic enzyme obtained from Carica Papaya, a useful tropical plant. Following a general description of the plant and the processing of its latex, the monograph includes an comprehensive review of the litera- ture on its therapeutic significance. The other papers or chapters are de- voted to a discussion of laboratory techniques. Hwang & Ivy's review of the literature is indeed thorough and the following comment to be made is not intended to convince the reader otherwise. But the authors did miss the scattered and indeed few references to the cosmetic use of both papain or the fresh latex from the fruit. At least one locally known cosmetic line offers papaya cosmetics in Florida. However the reference to its sensitizing proper- ties reminds one that Bromelin from fresh pineapple, another pro- teolyt!c enzyme, is also a sensitizer. It •s a well-done monograph, clearly illustrated, and definitely needed to fill a gap in the scientific literature on Papain and, by rela- tionship, papaya or pawpaw as it is also known.--M. G. dEN. T•E i\I^NUF^CTUP, E OF INTEP,ME- DIATES AND DYES, by G. H. Frank, M.Sc. (Leeds), F.R.I.C. Chemical Publishing Co., Inc., New York, N.Y., 1952. 177 pp. $4.00. This is a very brief discussion of d.ye manufacturing as done in Brit- ain. The plant and equipment are describedin outline. The author de- scribes the processes from the point of isolation from coal tar through the preparation of intermediates to the finished dyes. Emphasis is placed on preparation of intermedi- ates. Azo dyes, anthraquinone dyes, and sulfur dyes are described. The author does not mention that most of the more complex dyes are actu- ally mixtures of the several compo- nents produced in the reactions of the intermediates. Although this fact is well known in the industry, it is rarely mentioned in any publica- tions. From the standpoint of the chem- ist in the food, drug, or cosmetic field, the book will not indicate
