BOOK REVIEWS The book is copiously illustrated with diagrams showing numerical data, hut structural diagrams tend to be rather fewer than one might expect on such a subject; for example, there are no diagrams illustrating clathrate structures. There is no general index and this also would he useful; so-called Magneli phases turn up in many places and an index showing where the structures and the properties are discussed would be helpful. The book is very well produced, the printing is clear and pleasant to read, and the paper cover is substantial and likely to stand up well to all reasonable treatment. Themes which recur throughout the book are the nature of defects, their influence on structures and properties, and the thermodynamics of defect structures. Distinctions are drawn between structures with small numbers of defects and grossly defective structures. One of the most fascinating developments in recent years has been the recognition of metal-oxide phases with (one might say) almost innumerable metal: oxygen ratios such as the sequence Tirol, Tibop,Ti601,,. . . up to Ti,oO,o, with general formula. Ti,Ozn-1. These are said to he strictly stoichiametric phases. The geometrical explanation is in terms of the fitting together of blocks of structure. Other oxide series of the same general type are k n o m and one wonders what further discoveries along these lines will emerge. Order-disorder is another topic which occurs in many places and again one regrets

the absence of a general index. In conclusion, i t should be noted that this volume has appeared in little more than a year since the symposium was held and one must congratulate all concerned with its production on making i t quickly available to a much wider audience.

This Little book succeeds in a difficult but worth-while task. It presents most of the recent variations that have been devised for increasing the power and versatility of polruography and discusses the merits of each for analytical and other applications. The authors have been ~articulerlvsuccessful in exnlainine the

equations, approximations, and more equations. The discussion of alternating current polrtrogrrtphy is refreshingly good in this respect. Mastery of the material in this hook would not make one a n expert in the field, and it is doubtful that anyone completely unfamiliar with classical polarog-

raphy would benefit from this book. However, for the large and growing body of electroanalytical chemists this hook comprises one of the best brief discussions wailahle of modern polsrographic methods.

This book is basically a. laboratory manual for a series of gas chromatographic experiments. At the beginning a brief review is presented of the elementary principles of the method. Next, rather detailed instructions are given for the construction of a simple gas chromatograph. Actually, this instrument is to be assembled from a kit supplied by the Gow-Mac Instrument Company (the publishers of the book). The three following chapters offer advice on preparing columns, technique, and the testing of the assembled gas chromatograph. The main body of the manual consists of 12 gas chromtographic experiments, which make use of the assembled instrument. The first two illustrate the effect of carrier gas velocity upon column effi(Continued on page A218)

The remaining experiments illustrate the partition principle, the variation in separation efficiency through the use of different stationary liquid phases, the use of Molecular Sieve columns, and the prectical application of gas chromatography to several types of chemical problems. Essentially d l of the experiments are directed to the qualitative and quantitative analysis of materials. This book is aimed a t a rather elementary level, probably sdwneed high-achool or freshman college, and for this group should be quite satisfactory. However, for more advanced courses (e.g., Instrumental Analysis, Physical Chemistry, or Advanced Analytical) the level and sophisticat,ion of the manual is entirely too elementary. The "rate equation" is only passingly mentioned and the thermodynamic aspects of gas chromatography are neglected completely. Alternative injection and detection systems are not discussed, nor are nonanalytical applications of gas chromatography. The use of gas chromatography for studying the thermodynamics of solution systems and for studying adsorption systems is becoming increasingly important. Preparative separations based on the method are also important and should be included in a laboratory course, in my opinion. In summary, thirr manual should prove useful to those instructors interested in constructing their own gas ehromato-
