Abstract
1) Investigations were made on the pharmacological effects of pancreas hydrolysate on toads, mice, rabbits, dogs and rats.
2) Pancreas hydrolysate acts on pancreas through the central nerve in an organspecific way, and quickens its function both in its external and internal secretions.
3) There can be observed a definite difference between pancreas hydrolysate and insulin or kallikrein.
