direct precipitation method, the determination of sulfur in pyrites instead of barium sulfate, an expansion of the procedures of the analysis of brass t o cover the analysis of bronze, and an introduction to the principles of potentiometric titrations. The book is divided into three parts. Part I (7 pages) takes up general considerations of quantitative analysis and, among other things, stresses the necessity of a m a c y and points out the methods by which i t may he obtained. Part I1 (128 pages) is devoted to the subject of volumetric analysis. The correct use of measuring apparatus is first discussed. and then procedures for the determination of various substances by neutralization, oxidation, and precipitation methods are given. In Part I11 (93 pages) gravimetric analysis methods are discussed; also a number of procedures for the precipitation and conversion t o weighable products, and calculations of the amount of desired substance are given. In the Appendix (21 pages) the methods and apparatus for potentiometric titrations are outlined and several tables are given.

The material for this short course is given in the first four parts of the book. Part V is for those students who wish t o take a second semester in qualitative analysis. This section considers anion analysis in considerable detail and also gives procedures for the analysis of complex mixtures. The author has succeeded well in carrying out his intentions. The b w k is well written and is very nearly free of typographical errors. I t appears that too much attention has been given to cells, and to the occurrence and properties of many substances. There is also considerable repetition. Much of it has resulted from the author's endeavor to make the book cover both a shorter and a longer course in qualitative analysis. There is a wealth of material contained in the hook. Numerous problems with their answers add to its value. Sections on equations and theory are especially good. I t is the opinion of the reviewer that the book will be widely adopted. M. C. SNEED
