due to publishing restrictions. The use of both the standard "ladder" type configuratiojlal formulae and the modern plane projection type is somewhat confusing but does facilitate the understanding of the stereoisomerism of sugar molecules.
The book presents a difficult and complicated subject in a clear and succinct manner. The author intends the book for students "reading for an Honours Degree" and as a text for courses in carbohydrate chemistry. It is also to be recommended to reasearch workers in the field as well as a valuable addition to the chemist's library. D. H. RUSSELL CHEMICAL THERMODYNAMICS, by Irving M. Klotz. 369 pages, diagrams and tables, 15 X 23 cm. New York, Prentice-Hall, Inc., 1950. Price, $6.00. This text, in the Prentice-Hall Chemistry Series, is an introductory treatment of the subject from the phenomenologieal viewpoint. The statistical viewpoint is excluded entirely because the author believes that the statistical approach should be based on a previous introduction to quantum-mechanical concepts and should be presented as an independent and complementary treatment with emphasis on the broader scope. The outstanding feature of this book is the extensive use of sub-headings in outline form to indicate the position of a given topic in the general sequence of presentation. The first section begins with a chapter on mathematical apparatus followed by chapters covering the first, second and third laws, enthalpy, heat capacity, free energy, heat of reaction and various applications. The second section of the book is concerned with systems of variable composition introduced by a chapter on partial molal quantities.
The subject matter covered is the same as that of Lewis and Randall, but the order of presentation is different. Almost every chapter contains examples of analytical and graphical methods of solving various problems encountered by the chemist and, in addition, there are numerous exercises 'for the student.
On opening the book, this reviewer was impressed by the orderly arrangement, the printing and the paper, but, after reading it, felt that less space should have been given to simple mathematical steps, graphical and arithmetic methods. One should expect that students of chemistry have an adequate mathematical background for this subject. The mathematical introduction could be improved considerably. The author's use of DW and DQ, which he calls inexact differentials, to represent small quantities of work and heat, respectively, is a departure from the usual treatment and is confusing. Aside from the above criticism, it is believed that the attempt to write an introductory text suitable for a one-semester course has, in general, been successful.
