BOOK REVIEWS widely scattered data dealing with this subject. The tables of this chapter also contribute t o s. better understanding of the problem. Also of vital importance is the subject of resistance of insects and mites to chemicals which is presented in summarized form in ahapter 7. Again this is a clear presentation, but it probably could h w e been enlarged t o advantage. Certainly Rome of t,he points in this chapter deserve R more extended treatment. Another ' excellent chapter is headed Modem Insecticides and in it there are presented data on the importance of insect and mite control which should he of special interest to producers and consumers alike. Chapters which deal with the insecticide groups are fairly complete, carrying a vast amount of information in summarized form. In the preface the authors state that the book was not written for specialists in the field of economic entomology or the chemistr.~ of insecticides. This, in the opinion of the reviewer, would place decided limits on the usefulness of thir volume, as it is felt that very few laymen could read the book with perfect understanding. At least it will not hurt the speri&t to read it. The volume is well illustrated, well bound and printed, and textual mistskes are very few. Overall it is a n excellent review of a big field. C. R.

A considerable amount of meterid is available today for the expressed purpose of guiding young people in the selection of a career. This revised edition of a similar effort published in 1954 "is concerned with the work of scientists of d l kinds, but especially of those engaged in basic research." The author wisely elects to consider only a limited number of scientific fields. These include physios, chemistry, biochemistry, atomic energy, geology, biology, medical research, and conservation. However, within the individual areas, many different types of jobs are discussed which, in effect, broadens the coverage considerably. Discussion includes opportunities in industry, education and govemment. In the presentation of these areas much use is made of current discoveries; how they were achieved, and the present frontiers. These discussions alone should prove to be very informative and intriguing to the student. The reader is then introduced to artual job situations which will most likely be encountered in the field. No attempt is made to overglamorize a particulrtr career. The disadvantages, hazards, and apportunites of the various

BOOK REVIEWS careers are discussed in a clear and precise manner. The advantages and rewards, hoth tangible and intangible, are likewise clearly presented. Educational requirements are stated in terms of definite courses and years of training in order to qualify for the opportunities whioh may be available in the field a t the various levels. A very important chapter i~ devoted to the opport,unities for women in the sciences. The contributions of women to science, hoth past and present, serve as illustrations of the definite and increasing
place of women in this field. The author does not overlook the unique problems which will he encountered, but hastens to discuss the changing view of society toward women scientists An extremely helpful appendix contains tables of average salaries which presently prevail in the field. The tables are speoifio for the various fields. Sources of additional information concerning each field are listed. Another unique service is s. listing of colleges and universities which train persons in the various speoifio fields.

This book is number four in a series of collective volumes which eventually will cover tho entire field of organic andysis. ROBERTL. SILBER The first of the series appeared in 1953; it, American. Chemical Societv and two subsequent volumes, dealt largely Washington. D.C. with functional group analysis. The hulk of volume 4 is devoted to instrumental analytical techniques. It contains six chapters: 1) Determination of Organic Peroxides, 2) Enzyme Analytical Reactions, 3) Gas Chromatography, 4) Application of Nuclear Magnetic Resonance Spectroscopy to Organic Analysis, 5) Crystxllographie Methods of Analysis: X-Kay Diffraction and Microscopy, and 6) Application of Differential Thermal Analysis to High Polymers. The treatment of organic peroxides is comprehensive, covering volumetric, colorimetric, and instrumental methods of peroxide estimation and concluding with recommendations for specific types of peroxides and comparisons of available methods. An extensive bibliography is provided, and, as in previous volumes, critical evaluation and comparisons of methods are made throughout the text. In some cases, improved procedures, differing somewhat from those in the original literature, are described. The discussion is written with authority. The chapter on eneyme analytical r e actions is a very brief survey of enzyme reactivities with a few specific analytical applications. The important and rapidly developing field of gas chromatography is treated extensively in the longest chapter in the book. Although "the purpose of this chapter is to acquaint chemists with the potential of gafi rhromatography for organic analysis," the authom accomplish more than this. A considerable amount of general information is provided, in addition to the analytical applications. The concluding pages contain a series of tables in which are tilholated diverse specific applirntions, ranging from the aceumulation of thermodynsmic and kinetic data through application to foodstuff rhemi t . Iksrriptions of work and instrumentation done in the authors' laboratory augment the abundant recent literature in the field. There are avnilahle R number of hroad treatments of therelativelynew technique, XMIt spectroscopy. In the present chapter the stress is an applications of high resolution speetroscap? to structure determination of organic molecules; neither the theory nor instrumentation are discussed as fully as in some of the other treatments. C ~ a t doptics and morphology, X-ray diffraction analysis, and fusion methods of analysi~are the subject of Chapter 5. Disrussiona of principles and techniques (Continued a page A6401
