Formidable as the title appears, this volume contains, in addition to the technical procedures and definitions, much information which students of all the biologic sciences, including medicine, will find of practical value and interest.

Many biologic processes are either oxidation-reduction systems (i. e., involve exchanges of electric charges) or are affected by oxidation-reduction reactions. The chapter on Systems of Biological Interest includes discussions of sulfydryl systems, hemoglobin, several of the vitamins and hormones, as they are related to the subject. The chapter Bacteriological Applications covers many aspects of the electrode potentials developed and their effects on the metabolism of unicellular organisms. New chapters, not in the last edition, 1948, include applications of oxidation-reduction systems to pH determinations, metabolic cycles of integrated enzyme systems and the mode of action of antibiotics and chemotherapeutic agents. The author presents the material in an interesting style seldom encountered in technical books, and the
