BOOK REVIEWS peroxide procedures are given without any suggestions as to merit which would guide a research manenteringinto anew field. The hook is therefore an invaluable reference source for snecialists in the field but is extremely difficult to read. I t is therefore useless as a. text for either classroom use or for self study.

The field of chromatography and electrochromatography has expanded very rapidly in the past fifteen years, and "Chromatography," edited by Erieh HeftRALPHDANNLEEY mann, provides a complete, up-to-date Western Reserve Universitf, reference volume in this field. The book Cleveland. Ohio is written by s. number of scientists from various countries, each man contributing information in his specialized area. In
general it is both authoritative and camplete and should prove t o he a valuable reference, ~ ~~ i ~ i into d ~ two d h parts, and Applieetions ~ of~ Chromatography, the book provides a and descriptive account as well as the practical details and necessary references required for a particular separstion problem. In Part I , Fundanentals of Chromatoxraphy, the various types of chromatography are brought together and discussed under the headings of Adsorption, Partition. Ion Exchance. - , Molecular Sieve. as' and Electroehramstograpby. he theoretical aspects of these various types (Continued on page A64)

Tanford's "Physical Chemistry of Macromolecules" is, in this reviewer's opinion, an excellent and worth-while hook. I t s merit lies not only in the contents which i t covers, but more so in the manner in which the material is treated. This is done in an original, stimulating, and logical fashion, leading up from simple principles right into the full moat of the matter with many ramifications for general understanding and research. Especially noteworthy chapters are those on light scattering and on polyelectrolytcs. In view of the high quality of what iis presented, one misses a fuller treatment of many neglected areas, although i t is reeognired that in order to keep the volume within a certain size sacrifices were necessary. Still these ssorifiees w e not too well balanced. For a book leaning so heavily on transport processes the hydrodynamic section is all too brief and incomplete. The chapter on thermodynamics following a rather elaborate one on chain stittisties. does not make anv
lem. Thus, it is impossible for the reader to obtain appreciation of the effect of shear dependence on all transport processes, viscosity in particular. Again, these criticisms do not refer to what the book contains but t o what is omitted. Maybe the book should have been more clearly labeled as the physical chemistry of macromolecules in solutions, the topic i t mostly deals with. The
fore outside the frame of tho remainder of the book. I n conclusion. fmm the m i n t of view of didaetle approach and instrument of toaehing, and advance information, the book can he highly recommended for the areas which it covers.
