THE hook is aimed s t answering the question: "Wlat should a student gain from the study of science that will make him a happier, better-informed citizen of his oommunity?" I t is intended for use in a beginning course which is also a terminal course in chemistry. The contents %reorganized into eight units: "The materials of which the world is made," "The components of the atmasphere," "The states of matter," "The material of the earth's crust," "Radioactivity and atomic structure," "The periodic system: the Emdies of the elements," "Organic chemistry: the chemistry of the compounds of carbon," and "The chemistry of everyday life." Much of the usual material on writing chemical equations is included in an extensive appendix together with a discussion at arithmetical methods. This is consistent with the general tenor of the hook which avoids a heavy accent on problem working, yet the mare fundamental problems of moleoulrtr weight determination, stoiohiometry, and volume relationships are all introduced so that each student using the hook will be well acquainted with the necessity of exact quantitative work in the phys~cal sciences. However, the general accent on qualitative comprehension of principles avoids the common error of attempting to make all beeinnine chemi~trvstudents into ~roficientcalculators. Most of The material is presented by -stating the applicable theory and then showing how the facts support it. The authors have done sn excellent job of selecting for di~eusrionfacts and processes which the student already knows in a general way or which he will undoubtedly meet in the present world, and the economic and social implications of advances in chemistry are effectively illustrated. To eaeh chapter is appended a description of pertinent film strips and movies, a supplementary reading list, and a set of problems. Potential users of the text will probably he strongly swayed in their judgment by the relative accent on inorganic and organic chemistry. Such old standbys of inorganic chemistry as the Solvay process, the Lead Chamber proces8 and the Contact proceee rate only 30 lines all together, which will t hock some teachere. particularly when they note that over one-quarter of the book is
