According t o the preface, "this baok is designed for the non-technical university student who desires general chemistry as a part of a liberal education." The authors state also that the book has been used in mimeograph form a t the University of California for four years, and the experiments have been tried over a seven-year period. The assignments are designed to be covered in a one-year program of three hours per week. The book is divided into five parts as follows: Part I. Generd E*fierimnts-Bunsen Burner, Glass Working, Density, Factors Influencing Rate of Reaction, Temperature Changes in Liquid-Gas and Liquid-Solid Transitions. Part II. Weight Relatwns-Water in a Hydrate, Combining Weights. and Formula Determination. Part Ill. Volume Relefions-M. W. of Oxygen and Sulfur Dioxide, and Equivalent Weights. Part N. SolzUions-Effect of Temperature on Solubility, Fractional Crystallization, Ionization, Properties of Acids, Bases, Salts and Volumetric Analysis. Part V. There are 13 assignments in this seclion. Examples of these are: Chemical Equilibrium, Analyses of Baking Powders, Fractional Distillation, Hardness of Water. The appendix is only three pages and dws not include any of the usual tables. Among other things it includes an illustration of the graphic representation of data and brief first-aid instructions. Each assignment is followed by a series of problems, usually six or seven in number.
It is difficult t o understand why the authors chose the particular order for their material. The first experimental work is on glass bending, assuming no previous knowledge, and then Assignment 3 involves the use of acids of certain normality. I n order to understand the third assignment, the student must have some knowledge of normality. Then later on, in Assignment 13, we find a simple experiment, as 6nding the solubility of a salt. The baok does not include the usual experiments given t o study the properties of the common elements. The experiments are well written and for any one who desires a small manual on special topics, this should he an excellent book. C. E. WHlTE UNIVBRSITY OI
