Abstract
In rabbits, the pancreatic duct was doubly ligated and cut off between the ligations. The animals showed no abnormity in appearance and behavior. Sometimes a small reduction in the blood sugar was measurable a few days after the operation, but that the hindering of the passage of the pancreatic juice cannot be taken as responsible for this hypoglycaemia was proved by the control experiments. No definite variation was discovered by the further observations in the blood sugar level throughout. That the ligation of the pancreatic duct brings about an onset of the hyperglycaemia is thus disproved here also.
