Rhinoceros unicornis, male Jim in London Zoo. Duodenum. A portion, taken about 1 ft 6 in. from the stomach, showing the papilliform valvulae conniventes. Microscopic sections show that the papilliform processes are covered with villi. The interior of each process contained a number of follicles belonging to Brunner's glands. The ducts from these open upon the surface of the process between the villi. Brunner's glands were only observed within the papilliform processes, and not in the general submucosa of the intestinal wall. With haematoxyumlin they stained a vivid blue, in marked contrast to the pinkish purple of the surrounding tissue.
Gervais, who describes the histology of the small intestine [1875], makes no mention of Brunner's glands, probably his sections were taken from a point further down the intestine below the level of these glands. He, however, speaks of Crypts of Lieberkuhn lying between the papilliform processes. These were not seen in the present sections.
