Fig. 118. Plasma dilution, measured as % increment in 1/EI as previously defined, 

 in relation to total water load (% of Bo). Dog. Individual C solid points, individual 

 G' open points; 50 observations in 10 tests. All samples were taken at more than 1.0 

 hour after first administration of water. (The correlation coefficient is +0.66.) The 

 regression line as drawn indicates that the plasma was diluted 2.31 times as much as 

 the body as a whole. Data of Adolph and Kingsley. 



of the somewhat greater rates of urine output that follow single 

 ingestions (figs. 7 and 27). 



In a similar manner, each of the dilutions measured in samples 

 of blood is correlated with total water load (table 24). The in- 

 tensity of correlation is indicated by the coefficient r, while the 

 mean relationship is indicated by a proportionality, or slope of the 

 regression line, fitted by least squares or other approximate 

 method.

 body (% of Bo), in relation to time. Dog in control tests without water load. Means 

 of 4 tests on 2 individuals. Measures of dilution as in figure 116. Data of Adolph 

 and Kingsley.
