BOOK REVIEWS entitled Protein Molecules: Intraspecifie and Interspecific Variations, including a consideration of both homologaua and heterologous proteins. Other chapters devoted to more specialized forms of proteins include those on keratin, sclerotizatian, and blood coagulation. This group of chapters on special farms of adaption oi protein structure is rounded out by an excellent critique of problems of metnmorphoais and biochemical adapt&tions in amphibia. The present volume closes with a review of the comparative biochemistry of the alkali metals and a discussion oi the evolution of ion balance in intra- and extrscellular fluids. The continued high quality of scholarship evident in Volume 4 of "Comparative Biochemistry" gives the subscriber to all seven volumes a n exciting anticipation of soon having in his library the most comprehensive and critical treatise to be written in this area during the past two decades.

This monograph is a detailed, retrospective, somewhat personalized presentation of certain systematic atudies pursued by E. A. Ostroumov since about 1933. These studies were directed toward the use of weak organic bases for pH control and adjustment and as weak complexing agents in the hydroxide and sulfide precipitation8 of metals. In brief, methods are presented for the somewhat selective separation of certain metals based on the use of pyridine or 2-piealine in hydroxide precipitations and of pyridine or hexamethylenetetramine in hydrogen sulfide precipitations. Some of the findings are of lessened contemporary importance with the evolution of such techniques as precipitation from homogeneous solution ion exchange, and solvent extraction. Because of the limited audience to which this monograph should be of primary interest, the trrtnslztor and his puhlisher are to be especidy commended for this undertaking. The translation into Western European languages of Ruaaian monographs for the specialist often aids far more in surmounting communication harriers than the translation of many works of broad readership. Brief, page-to-page comparison of the original Russian work, published in 1959, and the English text indicates that the translation is complete and ielicitous.
