198 Chittenden and Lambert— Post-mortem Formation 
Glycogen as dextrose, 7°80 per cent. 7:80 per cent. 
Sugar, 2:91 After boiling with H,SO,, 3°63 
10°71 11°43 
It is evident that here, as in the preceding experiment, the sum of 
glycogen calculated as dextrose and the sugar equals the total car- 
bohydrates actually found, only when the sugar has been boiled with 
dilute sulphuric acid, in which case the agreement is, as before, 
almost exact. Plainly then, dextrose is not the only sugar formed in 
the liver, and if, as seems probable from our experiments, the sugar 
has its origin in the hepatic glycogen, it would be quite in accord 
with analogy to expect the presence of both maltose and dextrose. 
The ‘relative reducing power, before and after boiling with acid, 
is much the same as in the preceding experiments, viz: 79°9: 100, 
and indicates the presence of considerable of the body with lower 
reducing power. This portion of the experiment was duplicated 
with another 40 grams of liver from the same rabbit under exactly 
the same conditions as to time and temperature, with results almost 
identical with those obtained from the preceding portion, thus testi- 
fying to the accuracy of the methods. 
Sugar solution before boiling with dilute acid. 
10 cc. gave 0:0865 gram Cu=0°0444 gram dextrose=2°78 per cent. 
Sugar solution after boiling with dilute acid. 
10 c.c. gave 0°1080 gram Cu==0'0550 gram dextrose=3"44 per cent. 
The relative reducing power before and after boiling with dilute 
sulphuric acid is in this case 80-0 : 100. 
Experiments were now tried, to ascertain the influence of peptone 
on the formation of carbohydrates in the livers of other animals. 
Experiment 1X. 
A large cat in full digestion, fed mainly on proteid matter, was 
chloroformed, blood collected from the jugular vein and the liver at 
once removed. Two mixtures were then prepared as follows: 
A. B. 
50 grams sampled liver, 50 grams sampled liver. 
20 grams blood, 100 c. c. of water. 
50 c.c. of a 10 per cent. solution of peptone. 
40 c. ec. of water. 
These were placed in a bath at 38-40° C. 50 minutes after the 
death of the animal, and were kept there for 23} hours, with a con- 
stant current of air passing through A in order to render the blood
