BOOK REVIEWS 423 written by specialists in their respec- tive fields. The first two chapters serve as an introduction and cover the funda- mentals of detergency and deter- gent materials. The remaining chapters cover a general topic in industrial detergency. The topics include laundering, dry cleaning, textile processing, foods and bever- ages, dairy cleaning, dishwashing, metal cleaning and general indus- trial cleaning. Each covers a de- tailed discussion of cleaning com- positions, applications, equipment (some of which is highly special- ized), typical cleaning procedures and at the end of most chapters a brief discussion of the future trends of cleaning in that field. Related background information is also in- cluded. The authors have varied their treatment of their topic. Some dwelled at length upon equipment and application procedures, while others placed emphasis upon clean- ing compositions and the back- ground related thereto. The book is well organized as to the method of handling the subject matter as well as convenience to the reader. Since many of the fields are divergent, a reader primarily interested in one phase can cover the introductory chapters and the chapter of his immediate interest without losing continuity of the book. The book contains a wealth of information and in most instances a good number of reference sources are cited. Subject and author in- dices are included. "Industrial Detergency" should be of particular interest to sanitar- ians, supervisors of cleaning opera- tions and those individuals supply- ing equipment and cleaning com- pounds to industry--CHARL•.S E.

Charles Griffin and Co., Ltd., London W.C. 2, England. 1955. 546 pages, 6 X 9 inches, illustrated and indexed. Price 60s. Essentially this is a total revision of the 1929 edition including ma- terial from the B. P. 1953 and B. P. C. 1949. The principal fault in this book is the lack of identification of methods given. For example, under com- pound ointment of benzocaine B. P. C., page 456, the authors give an assay for zinc oxide and for benzo- carne. The B. P. C. gives only the assay for benzocaine. Therefore, the zinc oxide assay is included as the authors' contribution. But there is no such identification. A valuable addition would be a critique of official methods includ- ing some of the authors' own varia- tions or improvements. The book is well manufactured. No errors were noted. Many use- ful methods not ordinarily found for official products are included. The work is strongly British in flavor but the methods are appli- cable in any country. This is a valu- able book for all analysts.--M. G. DENAVARRE. ORGANIC SOLVENTS. Volume VII of Technique of Organic Chemis- try. Completely revised, by J. A. Riddick and E. O. Toops, Jr. In- terscience Publishers, Inc., New York 1, N. 55. 1955. 552 pages, 6 X 9 inches. Price $8.50. This is the revised edition of the original written by Weissberger and Proskauer, the former of which is editor of this series of books. Six chapters comprise the work. The solvents are classified by chemi- cal type. Physical properties and their selection follow. Two hun- dred eleven pages discuss physical

In going over the lists of solvents, practically all those commonly used in toilet goods were included. Tet- rahydrofurfuryl alcohol (or its es- ters) terpineol, hexylene or butyl- ene glycol are not included. Some plasticizer solvents, such as tri- cresyl phosphate are not given although camphor is included. Even so, the book is thorough with no errors noticed. The price is moderate.--M. G. r)ENAVARRE. COMPREHENSIVE INORGANIC CHEM- IS,R¾. Volume III, The Halogens, by R. C. Brasted. D. Van Nos- trand Co., Inc., New York 3, N.Y. 1954. 250 pages, 6 X 9 inches, indexed. Price $5.00. The third of an eleven volume series, discusses the chemistry of fluorine, chlorine, bromine, iodine and astatine. In each case, the history, prepara- tion, physical and chemical prop- erties, various reactions, and uses are included. Unfortunately, only two Freons are mentioned. No Genetrons or other fluorinated hydrocarbons as refrigerants or propellants are given. This is a minor point, however. Additional to the contents given abow, chapters on the hydro- halides, oxycompounds, interhalo- gens and pseudohalogens are in- cluded. Typical of the series, the book is well manufactured and fairly priced. --M. G. I)ENAV^RRE. TEXTBOOK OF ORGANm CHEMISTRY, by Carl R. Noller. W.B. Saunders Co., Philadelphia, Pa. 1953. 643 pages, 61/4 X 91/2 inches, illus- trated and indexed. This is an orderly presentation of the subject starting with the basic principles of the science and advanc- ing through the pages into the more complex chemistry of the day. An unusual and interesting addition is Appendix A--Pronunciation--six pages. The reviewer finds that he and his contemporaries are all mis- pronouncing many chemical terms. Silicones are discussed in four pages aliphatic sulfur compounds get fifteen pages both are ade- quate. The chapter on oils, fats and waxes is too scanty a coverage of a large subject. Phthalocyanines are not included in the chapter on dyes. The toluidines and p-phenylene- diamines are mentioned in the chap- ter on aromatic amines. FD&C colors are not mentioned. Fluoro- organics are included. It is a good text and a readable reference.--M. G. I)ENAVARRE. THE SCIENCE OF COLOR, Commit- tee on Colorimetry, Optical Society of America. Thomas Y. Crowell Publishing Co., New York 16, N.Y. 1953. 385 pages, 7 X 10 inches, illustrated and indexed. Price $7.OO. In preparation since 1932 this definitive account of the science of color opens in a popular vein and gradually carries you into the increasingly technical aspects of color, according to the jacket on the book. The committee who pre- pared this book consists of twenty- three people with L. A. Jones of Eastman Kodak Company as chair- man. Four additional people from "Kodak" are on the committee. Nine chapters cover everything from the historical uses of color, through the psychological, anatom- ical, physical and measurement of color. Twenty-five color plates and over a hundred black and white figures illustrate the text.
