The American Physiological Society has undertaken the publication a series of volumes to constitute a new Handbook of Physiology, aimed at "a comprehensive but critical presentation of the state of knowledge in the various fields of functional biology." Revision at ten-year intervals is planned. Tremendous interest and progress in research in the neurological sciences has apparently prompted the Society to publish first the section on Neurophysiology, while other sections are in preparation.
This is the first of three volumes to be devoted to neurophysiology. It is an admirable start on a most ambitious project to summarize and organize the present knowledge of physiology in its several divisions. Volume I consists of thirty-one chapters including an excellent survey of the history of neurophysiology by Brazier.
Each chapter is written by a recognized authority in the special field of knowledge which he reviews and evaluates, but the authors have not apparently been
