Total carbohydrates are not at all affected by the presence of 
blood, but the percentage of sugar is considerably increased, and in 
accord with the increase of sugar, is to be noticed a decided de- | 
crease in the percentage of glycogen. Evidently then the percent- 
age of sugar in the rabbit’s liver is increased in the presence of blood, 
which increase is due wholly to a more vigorous decomposition of 
glycogen. Moreover, whenever increase of sugar has been observed 
in our experiments a corresponding decrease in glycogen has as a rule, 
also been seen. In this respect, therefore, our results agree with 
those of Boehm and Hoffmann, as also with those of Delprat. See- 
gen, bowever, states in a later communication,* that in rabbits, 
glycogen is more rapidly changed than in the case of dogs, or in 
other words that the liver-glycogen of rabbits is less resistant to the 
action of ferments. 
In all of the preceding experiments with the livers of rabbits, it is 
to be noticed that the sum of glycogen, calculated as dextrose, and
