I n the fourth edition of this well-known textbook dealing with The authors have presented t o the teaching public another the fundamental principles of the subject, the author has followed textbook on general chemistry for college students, i. c., "for the same general order in the arrangement of the chapters as in the use of beginning college students." I t embraces thirty-nine the earlier editions. A chapter dealing with "Solubility" has chapters, each followed by a n exten~ivegroup of exercises and been added. The purpose of this book is, as in the previous questions. There are three sections devoted t o general review editions, to furnish material for the presentation of the general questions and exercises appropriately placed in the hook. The principles in courses intended primarily for students who have figures and illustrations are well drawn and attractive, and the had previous training in chemistry in the secondary school. I t outlines are helpful and fitting. At the close, the work includes is an essential part of the author's plan that the descriptive a fairly representative glossary and a n appendix containing the material necessary for the course be obtained from the companion CAEMISTRY by Latimer usual tables of constants.
