ted to "Organic Syntheses" (I counted 55 such citations) and which will therefore be unavailable to mast readers for some time. For some of these reagents the Fiesers have included complete experimental procedures, but for most we will have to wait until they are checked and finally published in "Organic Syntheses." The criticism of the series is the unavoidable one in a treatise of this type: one must often search through four volumes to find information about one reagent. This annoyance will increase as the series expands unless the publishers and the authors decide to combine several volumes into ealledive ones like the collective volumes of "Organic Syntheses." I strongly recommend the complete set of these books both to the practicing synthetic organic chemist (including graduate students) and to the libraries of those teachers of organic chemistry who wish to keep abreast of new reagents and new synthetic techniques.

The latest volume in the series, "Advances in Chromatography," this hook in-
cludes chapters on "Quantitative Analysis by Gas Chromatography" by Josef Novak; "Polyamide Layer Chromatography" by Kung-Tsung Wang, Yan-Tang Lin, and Iris S. Y. Wang; "Specifically Adsorbing Silica Gels" by H. Bartels and B. Prijs; and "Non-destructive Detection Methods in Paper and Thin Layer Chromatography" by G. C. Barrett.

The chapter on "Quantitative Analysis by Gas Chromatography" tackles one of the most important aspects of gas chromatography which has not, in this reviewer's opinion, been treated successfully elsewhere. The author has considered every aspect of the response of a detector to an eluting peak including the prediction of the relative molar responses for seven well known detectors: thermal conductivity, Martin's eas densitv halance. Scott's microflame, flame-ionization, eross-section ionization, electron-capture, and the argonionization detectors. The treatment of this material is mathematically very thorough and i t should be suggested reading and reference material for any graduate course in separations. The only limitation of this chapter is the diffic u l t ~in readabilitv which is nrohahlv the result of translation difficulties. The chapter on "Polyamide Layer Chromatography" consists of comprehensive review articles of all the papers on this subject up until March 1972. The subject matter includes sections on preparation of beds for bath analytical and preparative purposes and the application of this technique for various biologically important compounds. The chapter on "Specifically Adsorbing Silica Gels" covers this less well-known area which is developing a t a modest rate. The reviewer found the authors' treatment of the subject matter excellent because it is clear, concise, and gives a thorough overview of the subject. The authors have described the technique in general, considered the mechanism and application of these gels, and have also suggested where this field will advance in the future. The final chapter on "Nondestructive Detection Methods in Paper and Thin Layer Chromatography" consists of a review article which lists the reagents which may be used for color development of sample hands obtained with paper and thin layer chromatography together with various physical methods of sample band de. . tection. This hook, the reviewer thinks, will serve as a useful reference for most ehrarnatographers and graduate students.
