is in the liver that this change is effected. The sugar found 
in the lymph must come from the intestines or the liver ; but 
since the former contain none, it evidently must be taken up 
by the lymphatics from the liver-tissue. (D.) Horse in full 
digestion ; had eaten 10 liters of oats a day for the two 
previous days, and on the day of the experiment the same 
quantity at two different hours. The liver furnished 2-292, 
hepatic blood 1:128, chyle 0°222, lymph (from the vessels of 
the head and neck) 0:442, carotid blood 0-069, jugular blood 
above the ligature 0-050, portal blood above the ligature, 
0-065, inferior vena cava below the ligature 0-057 per cent of 
Sugar ; mucus of the small intestine, the intestine itself, mus- 
cular tissue of the heart, locomotor muscles, traces ; pancreas,

and urine, none ; synovia from the knee joint 0-142 per cent. 
As before, sugar exists in the liver, in hepatic blood, and in 
the contents of the thoracic duct, but now also in arterial and 
portal blood, the intestinal walls, etc. Moreover, since the
