Because of their rapidity and fairly simple practicability, titrimetric methods are widely employed, particularly for routine work. The redox reactions are especially useful and make up the great bulk of this important field of analytical chemistry. The textbooks always include discussions of the common reagents and give directions for their use. Hence there was no need to repeat such material in this monograph. I t presents an overview of the oxidatiou and reduction reagents that have been suggested for various determinations. I t gathers into one place infarmatitian that has hitherto been scattered throughout the literature. I t will and has been welcomed by analysts in chemical industry, food chemistry, pha~macy,biology, and medicine as well as by those interested in chemical education and research. The text is presented in thirty main divisions. The same pattern is used for each reagent. After s. brief introductory discussion (including pertinent equations, redox potential, etc.) directions are given for the prepamtion and stmdardimtion of the solution. One or more indicators are recommended. Then fallow par* graphs dealing with the determinstions that can be accomplished. The division ends with a list of the references to the literature. Thislatterfeatureisextremely valuable and more than 1100 references appear in these lists. I t should be noted, however, that though working direotions are given with regard to preparing the solutions of the reagents and regarding their stabiiities, no such details are provided with respect to the actual determinations. The reader is informed in a general way as to what has been published but is then left to his own experience and ingenuity or to the working directions that can be found in the journals. I t is assumed that the reader already is familiar with the fundamentals of titrimetry, whether oonduoted in the usual manner or potentiometrically. The reviewer bas found the book most interesting, instructive, and inspiring. The German is not difficult to read and many of the references are to English and American books and periodicals. Some Russian articles are included. The range of materials that may be determined with the aid of these newer or not so familiar redox reactions is truly amazing and accordingly this book deserves a place in the analytical section of every chemistry library. The book is well made and the cost is modest. RALPHE. OEBPER University of Cincinnati Cincinnati, Ohio (Continued a page A1083)
