T m seoond edition of this well-known book by the author has not been changed essentially in form. There has been added important new matter, and some of the material of the &st edition has been condensed without detracting from the value of the work. In the new material added there is much tbat is related to the biological sciences, thus stressing the importance of the subject in tbis closely related field of science. In addition the value of colloid science to industry is cleady shown in the chapters on contact catalysis and dyeing. This seoond edition fulfills the threefold purpose of the author in an admirable way. Students of this baok will have obtained s good survey of the subject and its theories. The suthor emphasizes the fact that colloid science is a definite part of physical chemistry. Unfortunately there are some bad errors of proofreading with some omissions in mathematical expressions that could cause students some trouble. The book, however, should find as useful a place in the American scene as did the &st edition. L. H. REYERSON MINNEBOTA MnramPowa, MINNE~OT*

"TABLETMAKING''should be on the handiest shelf to every tablet production man and every development pharmacist. We a11 recogni~ethat the subject tablet manufacture is a most difficult one to cover, and that there is no substitute for experience in this work. Nevertheless, the authors have turned out an exceptionally good manual. The book is replete with examples of diffioulties and very able suggestions on possible methods of ""rrwtinn -----The fact that all the equipment described is of English make offersno difficulties. The reader will see a t once that the descriptions apply equally well to most American made maxhines. CARL J. KLEMME

MOREcompletely "bilingual" than most foreign language dictionaries; the introductory material, including title page, preface, and list of abbreviations is in Spanish and English. Although it is scsrcely to be expected that an engineers' dictionary would cover chemical nomenclature very completely, still the coverage is better than fair. The choice is sometimes hard to justify, however. One Iinds "amino acid" and "amide," but no "amine"; "aldohexose" but neither "ketose" nor "ketone"; "peptone," "protochloride," and "nitrogen iodide," but no "aldehyde."
