angle immediately after the emergence of the latter from the portal fissure. The 
bile duct (Ductus choledochus) opens at the papilla duodeni about one or two inches 
(ca. 2.5 to 5 em.) from the pylorus; an ampulla may be formed.

naturally be inferred from this figure, but are situated more medially and are covered laterally by small intestine. 
Owing to the large amount of interlobular tissue, the lobules are mapped out 
sharply; they are polyhedral in form, and are 1 to 2.5 mm. in diameter. For the 
same reason the gland is much less friable than that of the other animals, from which 
it is easily distinguished.
