100 physiology of the pancreas. 



Summary. 



(1) Secretins from the echidna, wallaby, Australian water- 

 tortoise, and ibis are active upon the dog in causing a flow of 

 pancreatic juice. 



(2) Secretin does not appear to cause pancreatic secretion in the 

 echidna. 



(.3) The flow of pancreatic juice )>roduced by pilocarpine is 

 inhibited by atropine, while the flow produced b}' secretin is not 

 so inhibited. 



(4) Stimulation of the vagus nerve does not inhibit the secre- 

 tion due to secretin. 



(5) The pressure under which the fluid is secreted in the pan- 

 creatic duct is equivalent to 9 inches of the juice. 



(6) Pancreatic juice may be activated by leucocytes so that it 

 acts upon proteids.
