Fig 95. Course of increment in volume of distribution of trypan red given by vein 

 ("plasma volume") (% of Vo), during recoveries from tranfusion of citrated whole 

 blood (open circles) and from hemorrhage (solid circles). Eabbit, same tests of Taka- 

 hashi ('35a, '35b) as are shown in figure 94. The enveloping broken lines indicate 

 standard deviations, which are here 2 to 3 times the standard errors.

Fig. 96. Initial rate of net volume exchange (% of VoAour) in relation to initial 

 "blood" volume load (% of Vo). For each point 2 to 8 individuals were subjected to 

 hemorrhage (negative loads) or transfusion (positive loads) ; and the changes of volume 

 were measured over the period from 0.03 to 0.50 hour thereafter, and the period from 0.03 

 to 1.00 hour thereafter, respectively, as indicated in figures 94 and 95. The volumes con- 

 cerned are: the volume of distribution of trypan red (termed "plasma"); this volvune 

 divided by the hematocrit ratio (termed "blood"); and the difference of blood minus 

 plasma (termed "cells"). Data of Takahashi ('35a, '35b).
