396 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS ascribe unusual reactivity to freshly formed BB appears to us to be in the realm of speculation. We believe and have suggested that BB probably is the end product of an undesirable side reaction during oxidative hair dyeing whenever PPD is used alone. This hypothesis is in agreement with the more recent investigations from other laboratories. Scheme IV in Corbett's paper (4) shows BB as a (brown) end product. The studies of Dolinsky et al. (6) show that solutions of BB do not react with dilute peroxide and ammonia. These authors also disagree with Cox's suggestion (7) that azines are formed from BB under hair dyeing conditions. Finally, we cite Brody's conclusion (3) that Cox's evidence for the existence of azine dyes in dyed hair is based on nonspecific and qualitative color reactions. In conclusion, it appears that early investigators have overempha- sized the importance of BB for the development of color on hair from PPD/H202 solutions. The role of BB more likely is a negative one, i.e., its formation in the dye bath interferes with the development of the desired hair coloring species. MARTIN M.

Book Reviews THE CHEMICAL FORMULARY, Volume XIV, compiled by a staff of experts. Editor-in-chief, H. Bennett. Chem- ical Publishing Co., Inc., New York, 1968. 373 pages, indexed. Price ,$8. This latest volume in the series has followed the established pattern of providing basic general purpose formulations in a wide variety of fields. These are particularly useful to those desiring to test a concept quickly in several areas outside their daily experience. Also, the market researcher given the assignlnent of evaluating the potential of a new product in a broad range of applica- tions can rapidly screen it against the well established products listed in these formulations. As expected from a concise volrune dealing with so many diversified topics, this book has ninny strong points where a high level of sophisti- cation is achieved and where a•nple details are given, and other weaker areas where the information is in- eolnplete or a critical detail in the specification of materials or the co,n- pounding procedure omitted, e.g., in some of the formulations on plastic, eelnents and ceramics, caulks, seal- ants, and asbestos cement. The sections on cosmetics deter- gents, farm and garden, foods, bev- erages, and flavors are in general well covered.-•A. K^W^M- Gillette Research Institute, Inc. CIIEMICAL INSTRUMENTATION, Editor Clemens Auerbach, Vol. 1, No. 1, July 1968, publisher Marcel Dekker, Inc., New York. Subscription price for Volume 1, 4 numbers, $35.()(). According to the introduction to this first number of a new journal, it is intended to serve as a forum for the field of chemical instrumentation, to address itself to chemists, bio- chemists, biologists, engineers, etc. The emphasis of the journal is to be on instruments and instrument systems, primarily of chemical and biochemical 'w.erest. The field is to be divided into problems dealing with instrumental designs and tech- niques. In this first issue of the journal, it seems that the distinguished edi- torial board has selected papers which meet these objectives very well. Only one of the collection of eight papers and three notes, in this reviewer's opinion, fails to •neet the goals set in the introduction. The others report significant advances in 397
