 those features are not common to all types of ' ' dehydration. ' ' The

Fig. 131. Alignment chart showing relations among 17 variables. The chart is 

 read along any horizontal parallel. Each of the quantities was measured in relation to 

 total water load of dog in approximately stationary states, as shown in previous charts 

 which are here indicated. 



an exception to their supposedly general picture is, that decreased 

 oxygen capacity is not characteristic of deficit by water privation 

 (Flinn and Scott, '23). Any other categorical characterization of 

 all negative water loads is equally incapable of applying to all; 

 some are more useful than others in differentiating among its types, 

 depending upon the variability of the data, the goodness of the 

 correlation, and the ease of measurement.
