Fig. Tesselated appearance of columnar epithelium lining the pancreatic duct. (Magnified 200 diameters.) The epithelium is columnar, arranged ap- parently in a single stratum, and presenting a beautiful honeycomb appearance of closely- packed hexagons and pentagons, when looked at on its free surface. Further up, however, near the extremities of the ultimate ducts, the epithelium changes its character, and becomes more globular, as is shown in Jig. 63, which represents a portion of the epithelial lining of a duct, about ^-^ of an inch dia- meter, from the human subject. A certain ap- proximation is here seen to the form of se- creting epithelium, with which, however, it strongly contrasts in its clearness and free- dom from granular contents.
