Fig. 116. Increment in dilution (% of initial) of plasma and blood, and total 

 water load of body (% of Bo), in relation to time after a single ingestion (6.2% of Bo) 

 of water by stomach. Dog. Means of three tests, 2 individuals. Blood was heparinized 

 as drawn: 1/T, increment in ratio of non-erythrocyte volume to erythrocyte volume 

 (hematocrit) ; 1/Hb, increment in reciprocal of hemoglobin concentration (colorimetry 

 of CO-Hb) ; 1/Db, increment in ratio of water to dry residue in whole blood. Plasma 

 separated from this blood: 1/Dp, increment in ratio of water to dry residue; 1/EIp, 

 increment in reciprocal of refractive index of plasma minus refractive index of water at 

 17.5° C. ; 1/Clp, increment in reciprocal of chloride concentration of plasma. New data 

 of Adolph and Kingsley. 



by stomacli (figs. 116 and 117). Within the first hour after sudden 

 administration, dilutions are not parallel to body load ; thereafter 

 they are. 



After 1 hour, plasma dilution (fig. 118) is related to body load 

 of water independently of time, and also independently (within the 

 range of variability prevailing) of whether single or repeated ad- 

 ministrations of water be used. The latter is remarkable in view

Fig. 117. Increment in dilution of plasma and blood, and total water load of body 

 (% of initial state), in relation to time after giving the first of 10 portions of water 

 at 0.25-hour intervals by stomach (10% of Bo altogether). Dog. Six tests, 3 individuals. 

 Measures of dilution are the same in figure 116. Data of Adolph and Kingsley.
