Show Mil. 11. H. BURNE ON THE VISCERA [Feb. 7, February 7, 1905. H oward Saunders, Esq., F.L.S., Vice-President in the Chair. The Secretary exhibited, on behalf of the Hon. Walter Rothschild, F.Z.S., a pair of Gorillas, mounted by Mr. Rowland Ward. He remarked that these Gorillas appeared to be on the eve of becoming adult, and that they were probably from twelve to thirteen years old. He added that Mr. Rothschild had called his attention to the unusually large red patch on the head of the male, and to the absence of the patch in the female. This difference in the coloration of the sexes confirmed Mr. Rothschild's opinion that Gorilla castaneiceps of Slack was not a valid species or subspecies, but was based on individual variation. Mr. Frederick Gillett, F.Z.S., exhibited some mounted heads of the Rocky Mountain Goat {Haploceros montanus), and made the following remarks:- " I have brought here to-night, specimens of the Rocky Mountain Goat, with the object of pointing out a gland which lies at the base of each horn and acts, one might almost say, as a pad to it. Under the external skin these glands consist of a soft red tissue saturated with a milky substance, like the udder of a cow. In the specimen at our Gardens these glands are partially covered up by long hair at the present time, but in October and November they are more conspicuous. The older the animal, the more pronounced are the glands." Mr. II. H. Burne, F.Z.S., showed specimens made for the Royal College of Surgeons Museum from the viscera of the Indian Rhinoceros (A\ unicornis), known as " Jim," that had lately died at the Society's Gardens, and made the following remarks:- The specimens include parts of the following organs: Stomach *.-A section showing the line of demarcation between the cardiac and glandular regions. The epithelium of the cardiac region, as in other Perissodactyles, is similar to that of the oesophagus-a stratified epithelium with easily separable corneous superficial layer. The deeper parts of the epithelium project into the submucosa in the form of elongated papillae. These are peculiarly long and resemble very closely those in the oesophagus of the Horse. A microscopic section taken from the glandular region of the stomach, 1 ft. in front of the limit of the lower parts of the cardiac region, shows a deep layer (6 mm.) of peptic glands. The gland-tubules were about -04 mm. in diameter. A section taken about 1 ft. 6 in. in front of the last, from the * Owen, " Anatomy of the Indian Rhinoceros," Trans. Zool.
