§ 77. Pancreas of Reptiles. — The pancreas in Reptiles is a 

 light grey or yellowish, sometimes pinkish, coloured gland, con- 

 sisting of numerous ' acini,' giving origin each to a duct, the 

 acini being united by them, like the short stalks of grapes, in 

 bunches, about a larger duct; 

 such assr elates or ' lobules' 

 further uniting into ' lobes,' 

 and their ducts into a com- 

 mon canal, which terminates 

 either with, or close to, the 

 biliary duct in the intestine. 

 The lobes are separate in 

 Python, of a subcircular 

 flattened form, suspended 

 cluster-wise by ducts of from 

 six to twelve lines in length, 



before uniting into the com- 

 mon canal. 



The pancreas has a close 

 texture in herbivorous Che- 

 Ionia, forming a thin layer, 

 spread out in the duodenal 

 mesentery, fig. 305, where 

 it branches into numerous 

 lobes. In most Ophidians 

 and in minv Lizards it ore- PancreasaU( i s i i,een °iti ieTurt i e (C'(etoweji/((?as). ccxxxi 



sents a more compact form, fig. 301, /. There are intermediate 

 conditions of structure in the present class. The pancreas is 

 ramified in Menobranchns : it is more circumscribed in Menopoma, 

 where it forms a long, slender, yellow gland. It is rather broader 

 in Amphiuma and Triton. In the Frog, fig. 306, p, it is flattened, 

 elongate, narrowest at the emergence of the duct (opposite c), and 

 sending a process, which surrounds the gall-duct, as far as the gall- 

 bladder. In the Salamander it is long and narrow. It is thick and 

 pyramidal in Ccecilia alhiventer; straight, elongate, and slightly 

 forked in Ccecilia interrupta : it is ovoid in most Colubridce ; of a 



1 The relative size of the liver in Reptilia does not relate to, or throw light on, its 

 probable accessory function as an elaborator of the albumen and disc-cells of the 

 blood, or as helping to maintain animal temperature by the formation of grape-sugar 

 out of the nitrogenized elements. Dr. Jones, however, detected the presence of grape- 

 sugar in the liver of cold-blooded Animals at all periods of starvation.
