AB -  water was obtained by calculation in per cent of body weight within the different age groups. When calculated in this way, the total body water was found to be 77.6, 72.2, 59.5, 63.1 and 58.4 per cent of body weight, respectively, in the age groups listed above. In order to illustrate the changes in total body water during the total life span, the corresponding values of total body water and body weight were plotted against each other on a double logarithmic scale representing subjects ranging from the first month of gestational age to adult size. Data from previous investigation were included with the present observations. This graph shows that a gradual drying-out took place which was most pronounced during the first year of postnatal life. In other words, the gain in total body weight during this period was more rapid than the gain in total body water. The data for extracellular water were similarly analyzed. The correlations between extracellular water and weight plus height, per cent of weight, and surface area, were of the same order of magnitude with relative standard deviations of approximately 15.2 per cent. When the extracellular water volume was calculated as per cent of
