ment of the physical properties of the elements is extensive in each case. The numerous advances of recent years make it difficult to collect comprehensive data, on these elements, and their inclusion in one location makes this volume a valusble addition to reference materials availrtble on inorganic chemistry. This is particularly true of the organic compounds of boron.

Introduction to Qualitative Analysis
Durward C. Layde, University of Wisconsin-Milwaukee. Allyn and Bacon, Inc., Boston, 1961. 350 pp. Figs. and tables. 15.5 X 23.5 em. $3.75. This book is intended for use in the teaching of qualitative analysis in the second semester of freshman chemistry. I t is divided into three parts: Theory, The Metals, The Laboratory. The first part contains the topics usually treated in courses in qualitative analysis. In addition there are two good chapters, one on nomenclature of inorganic compounds and one on chemical equations. The first gives a goad elementary summary for naming compounds and ions; the second encourages the use of net ionic equations. The author is to he commended for inclusion of this material. The second i art includes metallurev
may not realize how much material is covered. For example, oxidation potentials for the wrious metals and their ions are often given, hut only in one case are they used in the text to show their use in the prediction of properties. Part three gives what appear to be satisfactory procedures for the classical methods. There are no experiments which familiarize the student with the properties of the ions before plunging him into worked-out procedures. This seems to be a serious lack, since it is likely to encourage a slavish following of the proeedures without an appreciation of the reasons for the directions and precautions given. The book is free from gross errors; one may wonder why the author writes an equation for the hydrolysis of thioacetamide in 0.5 M strong acid solution with one of the products acetate ion. Similarly, he is careful to write SnC4'- as the principal species of tin in the + 4 oxidation state in hydrochloric acid medium, hut writes Sns+ for the principal species of tin in the + 2 state in the same medium.
