the preface to the first edition, printed in 1916. The author feels that the ideal texthwk would consist of two volumesone of general principles, the other of descriptive chemistry. The present book is aimed to supply the material for the first volume, leaving the descriptive material to be obtained from the companion volume, published in 1929-"Reference Book of Inorganic Chemistry" by Latimer and Hildebrand [for review, see J. CHEM. Eouc., 6, 1004 (May, 1929)l. The hook is planned to be used also in eonnectian with the laboratory manual by Bray and Latimer, "A Course in General Chemistry." Revised Editidn, 1932 (for review see next page). The author indicates that high-xhool chemistry is prescribed for entrance to this course. The material is presented under various topics which may or may not he taken up by the instructor in the order in which they are presented in the text. The author has endeavored to leave as much flexibility in this matter as possible. Chapten are devoted to the following sub: (I) Kinds of Matter; (11) Weight kelati& in Chemical ~ e a c t i i n s ,~ t & and Moledes; (111) The Kinetic Theory; (IV) ~ o l & u l s r Weights; (V) Atomic Structure and the Classification of Compounds; (VI) Concentration; Acidhetry and Alkalimetry; (VII) Thermochemistry; (VIII) Electrolytic Dissociation; (IX) Valence; (X) Chemical Nomenclature; (XI) The Speed of Chemical Reactions; (XII) Chemical Equilibrium; The Effect of Concentration; (XIII) Types of Equilibrium; (XIV) The Effect U-RSITY 0.

The topics the University of California, according t o are well discussed and many problems are heterogeneous, in that there appears to be no verv evident reason for the order of its subject matter, the latter half possesses an evident sequence and an interesting continuity which binds the subject matter into a uniform whole. The student is given an introduction to the metals, first through the study of salts under the general chapter headings of nitrates, halides, sulfates, etc., following which the metals as such are discussed under the general headings of activi metals, metals obtained from oxide ores, and metals obtained from sulfide ares. This arrangement lends itself well t o a comparative study of the metals and should enable the student to correlate his facts t o good advantage. Such a viewpoint makes possible the development of greater interest on the part of the student and greater unity in the subject matter, both of which are well-recognized essential principles in the teaching of general chemistry. I n addition to the usual descriptive matter, radioactive substances and atomic structure are discussed a t some length in Chapter XI1 and the colloidal state of dispenion, together with some of its more important applications, is treated in Chapter XXIV. The final three chapters of the b w k are devoted to a discussion of the hydrocarbons and their derivatives. The book is well illustrated, is written in a clear and very readable style and possesses abundant material for a thorough course in general chemistry. GEORGE W. SEARS
