PANCREAS OF BIRDS.

space of the duodenal fold, and generally bent upon itself like 

 duodenum, as in the Hornbill, fig. 87, 5-. 

 It is there supported by the gastro- 

 hepatic and gastro-colic omenta. 



The structure of the pancreas is 

 conglomerate, like that of the sali- 

 vary glands, but the ultimate folli- 

 cles are differently disposed. In the 

 salivary glands these are irregularly 

 branched, while those of the pancreas 

 in Birds diverge in the same plane 

 from digitated and pinnatifid groups. 

 The substance is firmer than in Rep- 

 tiles, of a pinkish, yellowish, or brown- 

 ish colour. 



The ducts, figs. 85, 87, 88, r, r, formed 

 by the reiterated union of the efferent 

 branches from the component follicles 

 of the pancreas, are in general two in 

 number, which terminate separately in 

 close proximity to the hepatic and 

 cystic ducts, n ; but occasionally there 

 are three pancreatic ducts, as in the 

 Fowl, Pigeon, Raven, and Hornbill ; 

 in which case the third duct commonly 

 terminates at a distance from the other 

 two : in the Hornbill it proceeds from 

 an enlarged lobe of the pancreas at the 

 end of the duodenal fold, and enters 

 that part, at /, fig. 87. As a rule, 

 the pancreatic secretion is the first 

 poured into the gut, the cystic bile 

 is the last.
