NEW BOOKS imall amounts of 112 commoner or ganic materials, with structural formula, yield, and time required for the work, given for each example. Methods and apparatus forms lean naturally to those of European usage. Equipment is described which can be fashioned by the worker himself, if necessary. More elaborate apparatus are, however, included in the 62 il lustrations. The talents of the senior author in the academic field, and those of the
junior author in the industrial labora tory, are well joined in this effort. Widely scattered information has been successfully combined into a small guide book of preparative organic microchemistry. It is, therefore, recom mended as an undergraduate and grad uate textbook not only in microchemistry, but also in organic chemical courses. It can serve the industrial chemist as well as a supplement to more comprehensive reference books in the same field.
RECOMMENDED FOR FAST SWEEP POLAROGRAPHY...
THE NEW FS POLAROGRAPH® by S A R G E N T Specifically designed f o r hanging drop and anodic stripping techniques.
The FS POLAROGRAPH is designed with both cur rent measuring and voltage application circuits adapted to the fast voltage sweep— hanging drop electrode technique, as described by Irving Shain of the Univer sity of Wisconsin. This method provides the peakshaped current-voltage curve characteristic of polarography at fixed elect rodes, providing somewhat increased sensitivity in many cases and permitting the trace analysis technique of anodically stripping the elec trode following electrolytic I concentration of the sample.

Gas Chromatography. D. Ambrose, B. A. Ambrose, vii + 220 pages. George A'ewnes Ltd., Tower House, Southampton St., London. IF. C. 2, England. $5.60. Reviewed by Warren W. Brandt, Kansas State University, Manhattan, Kansas. This book is the newest in the series of Newnes Practical Science Books. The authors state that it is aimed at the beginner and emphasizes the prac tical aspects of the subject. However, they have backed up the practical with a helpful treatment of theory so that the book should appeal to a wide range of gas chromatographers. In the reviewer's opinion the authors have done an excellent job and the book should satisfy a very real need at the present time. The number of people applying the technique of gas chroma tography is still increasing at a good rate. The literature of the field is be coming voluminous. This volume col lects the information which one needs to know. It covers the why anil how of gas chromatography without getting lost in the extreme detail of theory or practice. After a general introduction the book takes up the various parts of the ap paratus. The theory of separation, fac tors influencing columnar performance, qualitative and quantitative analysis are all covered. Chapters are devoted to the special techniques of gas analysis, preparative scale operation and gassolid chromatography. In many of the chapters the salient points are con densed at intervals to provide conven ient guides to better understanding and improved performance. The treatment of the theory takes one well into a more than adequate un derstanding. The presentation is straightforward and easy to follow. The significance of the equation is translated into the effects which opera tional parameters have on results. There are small points which some readers may find inconvenient. First among these is the fact that the book had to be written many months before it appeared in print. As a result there are several items which receive rela tively light consideration. Examples would be temperature programming, glass bead and capillary columns, and the presence of C g in the C term of the van Deemter equation. Some of the British words vary from American us age, such as "lagging" for "insulation" but this is not serious. The advanced chromatographer will note fine points which have been glossed over, but this
