book reviews very brief, and will not lend itself to independent study by the average student. Remarks by this reviewer on the procedures for qualitative anslysis in the first edition are still appropriate. For those teachers who still give qualitative analysis as a part of the introductory college course in chemistry this text is a good one.

The authors' intention is to present a practical introduction to thin layer, column, and gas-liquid chromatography for the individual who is not acquainted with these techniques. They have succeeded in presenting, in a clear and concise manner, a guide to the techniques which are essential to the beginner. The book is divided into six cliapters, an introduction, thin layer and column chromatography-choice of a system, thin

layer chromatography, column chromatog,,h, gasdiqnid chromatography, and the literature of chromatoeraohv. In
The most successful chapter is the one on tlo. It contains detailed discussions of techniques, procedures, and applications along with a number of practical hints on procedures of the sort that are usually gained only after long experience. The beginner can easily use this chapter as a laboratory guide. The chapter on column chromatography is less complete and lacks some of the detailed treatment given to tlc. However, a particularly good feature is a discussion of the use of tlc as an aid in choosing conditions for column chromatography. The chapter on gas-liquid chromatography is the Least satisfrtctory. I t is a t best a brief introduction to the simplest techniques. Considering the great number of applications for gss-liquid chromatography a more complete treatment of the subject is in order. A very useful technique, temperature programming, is only disoussed in a very brief way without any specific examples. I t is doubtful that a front view photograph of specific gasliquid chromatography equipment is of any value to the student. The chapter contains three of these photographs, none of which show anything about the internal workings of the equipment. The most serious drawback is found in the introductory chapters which attempt
to define terms and present theoretical concepts. The brief discussion of theory centers around arti it ion chromatoaritnhv while the majoi portions of the Lxi the chapters on techniques center around adsorption chromatography. The section on theory of gas-liquid chromatography is one paragraph long, and states that the theory is complicated. A reference is given to the books by DalNagore and Juvet, and Heftmann, which contain discussions of the theory of gas-liquid chromatography. I n short, the text ably presents the how of chromatography, hut not the why. ROBERTSILBERMAN Stale University College Codand, 1I1mYork Order and Disorder in the World of Atoms

This little hook is an excellent popularization of one of nature's grandest themes: order and disorder often coexist inseparably from each other. I t avoids both the language of mathematics and the coneept,~of thermodynamics, yet is (Continued on page A988)
