THIS is the second edition of a book which has been widely used for the past ten yews (see J. CBEM. Eouc., 22, 467 (1945) for a review of the first edition). Although the titles of the 39 ohapters are the same in the two editions and the size is about the same (957 pp. to 1004 pp.), the text, statistics, illustrations, and references have been brought up to date. In both editions the important chemical processes have been resolved into the series of unit operations and unit processes comprising the process. Where possible the heat of reaction is given for the process shown in a chemical equation. For minor chemicals, an equation and a few lines of description of production and uses suffice.
Three chapters give a general introduction sndexplain unit operations and processes; nine chapters -discuss mat&als such as water, fuel gases, ceramic industries, and the like; nine chapters cover the inorganic process industries, salt, caustic, chlorine, sulfuric acid, ammonia and the like; this leaves eighteen chapters for organic process industries, from detergents, sugar, and fibers to chemical warfare agents. The index is detailed and lists all subjects and compounds discussed. In the new edition the same problems are placed in the appendix to the book. Each chanter concludes with a list of the sources of information. Because of the large number of chemicals and processes discussed, this hook will continue to be used widely by both chemists and chemical engineers as a first source of information. KENNETH A. KOBE

VOLUME I of this English text was reviewed a little aver a year ago and now Volume I1 has appeared to complete this entry into the field of texts on unit operations of chemical engineering. Volume I covered fluid flaw, heat transfer, mass transfer, and their interrelation as the fundamental mechanisms of the rest of the unit operations. In Volume I1 the authors have done a good job of applying these fundamentals to the other unit operations and to the design of commercial eauioment. Thev have fallowed the recent trend of grouping the unit operations according to certain common elements. Thus all of their unit operations are grouped as follows:
