Dr. Jones, however, detected the presence of grape-sugar in the liver of cold-blooded Animals at all periods of 454 ANATOMY OF VERTEBRATES. 306 compact triangular form in the Rattlesnake,1 where it is closelyattached to the commencement of the intestine, and is perforated bythe biliary ducts. The pancreas is small and flattened in Lizards,usually dividing as it recedes from the attachment by the duct tothe duodenum into a portion accompanyingthe biliary duct, and another extending toor towards the spleen. It is very small inthe Iguana. In the Crocodile the pan-creas is divided into two elongated lobes,and sometimes sends its secretion into theduodenum by two ducts. In Chelydraserpentina the pancreas extends from thepylorus some inches along the duodenum,dividing and again uniting, forming a loop,and giving off a process which extends tothe spleen. In the Turtle ( Chelone Midas)the pancreatic duct terminates on a pa-pilla, which projects into the terminal ex-pansion, or (ampulla, of the pancreas in carnivorous Terrapins {Emys)
