This new textbook, falling generally in the area of snslyt~icalchemistry, emphasizes chemical equilibria and the physical chemistry of sohtions. In the preface, tho aothor states: "Because of the wide variety present in evolving college chemistry programs, this text is an ntt,empt to steer a middle path between repeating too much of the material covered in the general or element,avy physical ehemist,ry eonmes and assuming more fluency in chemical theory than. sophomores and juniors are likely to have." The attempt is qnite snccessfol, and the sut,hor and prtblisher should be congrattdxted on the quality of the hook and its freedom from significant errors.
