This second edition of the 1949 version offers a fund of information that, if covered completely, would be sufficient for a three-semester general chemistry course. I n this regard, the text provides a wide range of individual subject matter selection. I n general appearance, chapter order, and suhject matter, the revised edition is very similar to the first. Most of the chapters have been rewrie ten somewhat, particularly in providing up-to-date data. Several chapters, notably the one on Solutions of Electrolytes, have been rather completely redone. Arrhenius has been relegated to a brief historical comment with the major portion developed by means of the BdnstedLowry concept. I t does, however, seem somewhat inconsistent to utilize the H + ion in the discussion of the common ion effect and the pH scale after writing about the H,Of ion, even though H + is designated "an abbreviated farm."

The reader will find here also, however, insights into the genesis of some of the great chemical feats of these eminent chemists. He uill get an idea of the tremendous burden of work which they voluntarily assumed as laboratory men, teachers, and miters. Regularly they expressed their disgust with all things chemical and noted their periodic attacks of "semester fatigue," the inevitable result of long hours in poorly ventilated labarstories and a t writ,ing desks, where they toiled without benefit of secretaries or typewriters. The divergent personalties of the two men are plainly seen in the letten. Liebig, fiery, impetuous, and ruthless in his treatment of those who did not agree with him, was often admonished by the calm, even-tempered WBhler, who though only three years the senior talked more like a much older brother. Thia disparity in character may well have been the basis of this unusual friendship in which two men, though working in the same science and often on the same topics, never showed Volume 37, Number 5, May 1960
