1. The blood diastase decreases after meals, injections of glucose, glycogen, and insulin,
while anæsthetics and injections of starch cause a slight increase. 2. Since pancreatectomy
causes little or no change in the amount of circulating diastase, the pancreas is not the main
source of blood diastase. Ligature of the pancreatic duct does not result in any striking
change in the diastase content of the blood in the course of one to two weeks. 3. Since

3. Since definite variations can be induced in the blood diastase by injections of insulin, glycogen, etc., it appears likely that the circulating diastase is not entirely a waste product on its way to excretion.
4. Evidence is adduced that variations in blood diastase are probably due to its being taken up or given out by the liver cells, etc., according to the requirements of the body with respect to the glycogen glucose, probably in association with insulin.
