The subject of the exchange of fluids in man has developed so rapidly and to such proportions that a review of it by some one who can speak with authority is badly needed. Peters is qualified to undertake such a review by his many years of study, as well as by his own many contributions in this field. Expressing the opinion that the conception of vital activity should be banished beyond the horizon of the research worker, he emphasizes the significance of physicochemical forces in the control of fluid exchange.
The subject is developed in twelve chapters. It may be considered in three parts:
The first part deals with the distribution of fluids in the body. The physicochemical principles underlying the passage of water and solutes in and out of the different compartments of the organism are presented, with special attention to the conclusions of Starling and the modification of
