molecule exactly balance and render it neutral. Such orinci~lesas the commonion effect;solubility &duct, and complexion formation. which are derived from the law of mass action, are referred to throughout the text but are not derived or explained in it. Doubtless it is expected that the instructor will do this for the class. The scheme of analysis is the usual hydrogen sulfide separation, ammonium polysulfide being used to separate the divisions of Group 11. Also as usual the pages devoted to the anions are ahout onehalf as numerous as those devoted to the cations. I t is the opinion of the reviewer that close connection between theory and practice has been attained and that the hook will prove very useful in teaching qualitative analysis.

This hook is intended for sophomores who have had general chemistry and whose training does not demand the mathematical treatment given in the more advanced courses in physical chemistry, hut whose interest in the sciences calls for some knowledge of the subject. This hook treats mostly of the subjects taken up in the mare advanced course, hut in a more elementary and less mathematical fashion, however, nor hesitating t o use mathematics when necessary. It attempts t o give the student a view of the usefulness of physical chemistry, and a working knowledge of the subject through its description of methods and illustrations of apparatus. In an attempt t o give the student a broad view, some material has been introduced which appears t o he rather advanced for second-year chemistry, hut most of the subject matter can he grasped by the serious student. A knowledge of organic

chemistry would seem to be very desirable before considering such subjects as catalysts and proteins, and body catalysts. Hydrogen ions and the various methods for their determination are covered quite thoroughly. Chapters which are found unsuitable or too advanced can readily he omitted and still Leave an abundance of material. The course as given by the author consists of two lectures and one three-hour laboratory period each week for one semester. Laboratory may he optional, in which case demonstrations should accompany the lectures, and a number of these are included in the text. A list of suggested experiments is mentioned hriefly in the Appendix, so that by reference to the main portion of the text, they can be performed by the student without much help from the instructor. Seventy-nine tables are included to illustrate laws and theories and supply data needed in calculations and problems. Exercises and problems a t the end of each chapter serve as a review and test of the student's ability to reason. Numerous references to original articles are given, many of them to this year's publication. qeachers who are giving courses in elementary physical chemistry to students interested in the general sciences should find this book very helpful.

The second edition of Kamm's "Qualitative Organic Analysis" follows closely the plan of the first. The additions necessary to bring the work up-to-date have resulted in an expansion in size of approximately twenty per cent. The solubility behavior of organic compounds is first treated.
