"Chemistry and Our World" attempts t o teach all of the "modern" asoects of the role of chemistry in our lives. As such, it spends about 175 pages giving a brief, nonmathematieal introduction to the basic concepts of chemistry such as the scientific method and the principles of measurement, matter, energy, atoms, molecules, compounds, chemical changes, and nuclear transformations. This introduction is followed by approximately 275 pages dealing with most of the important "relevant" topics which are usually covered in such a course. There are chapters on industrial chemistry (25 pages), organic chemistry (40 pages), polymers (20 pages), biochemistry (85 pages), thechemistry of the soil (15 pages), the chemistry of the hydrosphere (25 pages), the chemistry of the atmosphere (30 pages), and the role of energy in our lives (45 pages). The problem of pollution is prominently discussed in the last four chapters and mentioned in several others, where appropriate. Another subject of current interest, drugs, is discussed ip the chapter dealing with biochemistry. The writing style is generally good and the book is easy t o read.

In the library possessed by a typical practicing chemist, there are usually just a few works that can he justifiably labeled "constant companion." To the analytical chemist, Laitinen's "Chemical Analysis" definitely bears this label. Students who have gone through courses for which "Laitinen" was the assigned text do well to keep this single-volume source of the principles and practice of analytical chemistry. For the production of a second edition, Walter E. Harris, Professor of Analytical Chemistry a t the University of Alberta, has become joint author with Professor Laitinen.

Like the original, the new edition is designed mainly as a text for the advanced undergraduate-graduate level student. The wide coverage, inclusion of many numerical problems, and extensive bibliographies will obviously appeal to those who teachor practice analytical chemistry. Although praced u d details can hardly be included in a work of this type, the various topics are illustrated by reference to goad selections of applications. As might he expected, separations are given extensive treatment. After dealing succinctly with classical methods such as precipitation and volatilization, the theory of liquid-liquid extraction is developed. This leads into an admirably concise but informative treatment of the various forms of chromatoeraohvand their uses. In view of the

Although instrumental methods of analysis are stressed, the importance and intrinsic accuracy of classical methods are not overlooked. We are not allowed to foreet the sir-

compactness, despite the inclusion of much new material. This has been by judicious shortening of the treatment, or by elimination, of a few of the topics in the first edition. Although the style of writing is compact, it is very readable. The entire work has the ring of authority, as is to be expected from the prestige of theauthors. However, it is significant that Laitinen and Harris devote nearly one-half of the preface t o the acknowledgment of the help received from others. The

Dixon, editor of New Scientist, contends that this is still s fundamental goal of science as is the coeval impetus to intelligibly understand the world. Interestingly, Dixon does not comment upon the historical usage of the word "emolument." In Bacon's time, it meant benefit and comfort and that is the theme which Dixon stresses as the always proper social ouroose of science and teehnoloev. .., Yet. a t least in the 11 3 .emolument now rommonl\. rignifies profit derived from employment ur compensation for the performance of services.
