moments that the difference in sugar-percentage between plasm and 
chamber-liquid does not correspond to what we should expect after 
the analogy of what was stated with ultra-filtration. With a rapid 
drop in the sugar-percentage of blood it will therefore be quite 
possible for the relations to be temporarily reversed, so that the 
chamber-liquid shows the greater percentage. In this way we can 
satisfactorily explain the very diverging differences in table I. But 
when they are compared in a large number of experiments, we 
may expect the chamber-liquid to show the lower figures in the 
majority of cases. We may further expect that in the mean values 
of a large number of figures the same relation between chamber- 
liquid and plasm will be shown which we should expect if this 
chamber-liquid was, not a dialysate, but a quickly-flowing ultra- 
filtrate. And when we find a mean difference of 0.044 °/, between 
blood-plasm of the ear-vein and chamber-liquid, we have a right to 
conclude: Provisionally the phenomenon observed in vitro of the 
combined bloodsugar which behaves as a colloid, is confirmed in vivo:
