The contents comprise the translators' preface of about two pages and the author's preface to both the first and second German editions covering about fovr pages, table of contents of three pages, somewhat more than four pagrs devoted to li9tiog all of the symbols u e d in the text, a Mathemaficsl-Physical Introduction of 34 pages, 637 pages of t e r t and finally an author and subject index of 27 pages. I n addition to tabulated data the text earrie. 99 illustrations. he book conforms in sire and general appearance t o the other books of the International Chemical Series. ro familiar t o chemists. The translation is very well done with very few errors noted by the reviewer. and in giving this translation a very valuable service has been performed for American ehemioto. The reviewer knows of no book of this size which presents the subject of theoretical chemistry in ~ u c hdetail and for the most part so modern io its treatment. The avthor har avoided mveh repetition in the text by referring to equation3 by number. The features of the book which appear unique to the reviewer are the portions of the book dealing with ~olutionsand the structure of matter. The translators have rewritten the portion on solutions for t h b translation introducing a brief discussion of the modern theories of Miher, Debye, and HOckel, and have added many footnotes throughout the text. This har increased the value of the book t o American chemists. The portion of the book on the structure of matter appears to be the moat interesting part. It in a clear, logical presentation of the subject that is very timely and which by itself should commend the book t o American teachem and investigators. 1. C. W. *AZBR Colloid Symposium Monogrsph.

This volume contains twenty-two entirely indepuldent p a p v s which were presented a t the Third National Symposium on Colloid Chemistry held June 17 t o 19, 1925, a t the University of Minnesota. I n the Pmeword the editor says, "With this Monograph the Colloid Committee of the National Research Council firmly establishes a series of important annual publications. I n Volume I were collected the papers presented a t the Sicst Colioid Symposium (University 01 Wioconrin); in Volume I1 the paper. read e t the Second Colloid Symposium (Northwestern University) were pubii.hed; and in Volume I11 we now offer the papers read a t t h s Third Colloid Symporium (University of Minnesota). Aa ~ s u a l ,theory and applicarion are both given adequate attention. Medicine and agricultvrc are prominent, butso are orientation of moleculer. surface tension, and electrokinetic potential. Professor Herbert Preuodlich, a. the foreian guest of honor a t the symposium, made a notable cootribution t o the disc"s3ions. His paper is a valued oart of t h k volume." The papers praeoted are listed below: 1. "On the Electrokinetic Potential," by Herbert Preundlich. 2. "Molecular Weight and Solution," h y Wilder D. Bancroft. 3. "Some New Aspects of the Surfaee Tension of Colloidal Solutions Which Have Led t o the Determination of Molecular Dimensiaos." . bv P. Leeomte du NoBy, Sc.D. 4.
