Clinical Chemistry ACS Symposium Series No. 36 Donald T. Forman and Richard W. Mattoon, Editors Based on the Annual Lecture Series co-sponsored by the Chicago Sections of the American Chemical Society and the American Association of Clinical Chemists. This new volume is a compendium of current information on topics that have a clinical chemical basis but which are also of interest to specialists in clinical areas such as pediatrics, endocri nology, and hematology. Ten chapters examine the etiology of disease and diagnosis as well as describe technical advances which can be applied more practically in the near future. Clinical chemists, biochemists, and hospital pathologists, universities, and training programs as well as medical specialists and laboratory technol ogists will find valuable material on: • separation and characterization of hemoglobins, measurement of calciotropic hormones, competitive protein binding assays • prenatal detection of genetic diseases, neonatology, blood gas abnormalities, clinical enzymology • modern liquid chromatography, trace metals in biological fluids, drug interference in laboratory testing

sants including the less-known and utilized compounds. Throughout the book, metabolite information is avail able if applicable to the particular an alytical method. The book for the most part is a re view of published analytical methods that are accurately documented. Few if any comments are original with the current authors. This is not recom mended as a textbook but would serve as an excellent reference book to cir cumvent extensive literature search ing for information relative to the analysis of biologic specimens for spe cific drugs.

Reviewed by John G. Cobler, Analyti cal Dept., Dow Chemical Co., Mid land, Mich. 48640 "Fractionation of Synthetic Poly mers" is a collection of seven indepen dently written chapters on the princi ples and practices of practical meth ods of polymer fractionation. E. F. Casassa authored the chapter on phase equilibrium in polymer solu tions. The thermodynamics of liquid mixtures are reviewed, and the simi larities and differences between mod els for simple mixtures and polymer solutions are discussed. The FloryHuggins lattice theory is used to de scribe phase separations in binary sys tems. Newer theories consider the noncombinatory entropy of mixing and appear to overcome some of the inadequacies of the Flory-Huggins treatment. The chapter concludes with a table of symbols. I t would have been helpful if the other authors had done likewise, particularly since the same symbols are not used through out. K. Kamide discusses the theory and principles of molecular weight frac tionation in binary systems by succes sive precipitation and successive solu tion. Experimental and computer sim ulation calculations are reported. Un fortunately, 50 pages of figures are in serted in the center of the chapter. I found it difficult to maintain a conti nuity of thought when searching through 50 pages to find a figure relat ed to the text discussion. E. M . Barrall I I , J. F. Johnson, and A. R. Cooper prepared the chapter on column chromatography. The authors state that a detailed review has been sacrificed in order to present a coher ent picture of the method that could be useful to the experimentalist, an undertaking that was successfully ac complished. The chapter reviews in-
