surface is covered witli fine conical papillae, among which, here and 

 there, regularly over its whole extent, jare scattered fungiform papillae 

 of a white colour. These papillae are aggregated in a row along either 

 side of the tongue. On the posterior portion are two large circum- 

 vallate papillae of whitish colour, situated symmetrically on either side 

 of the median line. Behind these the conical papillae become large 

 and soft. The specimen under observation showed a number of trans- 

 verse markings, corresponding apparently to the rugosities on the 

 palate ; there were also some transverse markings or cracks observed 

 on the posterior portion. 



The epiglottis is of large size ; and there is a large pouch-like 

 cavity between it and the back of (he tongue. 



The cfsophagus is about 1.5-16 cm. in length ; at its lower end, 

 immediately before entering the stomach, its mucous lining becomes 

 thrown into longitudinal folds and becomes thickened. 



'Y\\e stomach \^ in general outline essentially like that o{ Sus scrofa. 

 When laid out flat it measures 12*2 cm. in its long axis and 8-3 cm. 

 in depth between the two curvatures. To the left of the oesopha- 

 geal opening is a conical pouch-like projection arising as it were from 

 the left upper and posterior part of the viscus. The walls of 

 the pouch are thick, and have longitudinal markings of bands 

 of fibres running on the surface, directed towards the apex of the 

 cone. On opening the viscus, it is found that the mucous mem- 

 brane of the pouch-like cavity is very rugose, and that there is a well 

 defined constricting ring developed on the right side or the side next 

 the oesophageal opening which separates the pouch from the remainder 

 of the gastric cavity. The thickened epithelium, of the oesophagus 

 extends some distance over the lining of the upper wall of the stomach 

 around the cardiac orifice, and is so folded at the latter point as to 

 form a sort of valve as in the Pig. The transverse ridge which 

 marks off the antrum pyloricum is less marked than it is iu 

 the Pig. Towards the pylorus the walls of the stomach become 

 considerably hypertrophied. The pylorus can be completely occluded 

 by an oval pad situated on the side of the lesser curvature, which 

 fills up com23letely its crescentic and concave under portion just as in 

 the Pig. 



The S7nall intestine is long but of small calibre, and when in situ is 

 situated chiefly on the right side of the abdominal cavity. The duode- 

 num jnakes a moderate-sized loop to the right before it crosses beneath 

 the ascending colon. The Peyer's patches are scattered through the 

 intestine ; but there is no large patch at the lower end of the ileum like 

 that found in the Pig. The last part of the ileum ascends to the top of 

 the C9ecum, which lies rather to the left side with its apex upon the 

 bladder. The cacum is saccular, measuring /'l cm. in length. Its 

 outline is straight, in contradistinction to the irregular crenated out- 

 line of that of the common Pia;. A strong- band of muscular fibres 

 runs down the internal or left surface; a second band runs down the 

 external or right surface ; and extending from the ileum to the pos- 

 terior surface of the caecum is a third band. From the toj) of the 

 caecum arises the colon, which has a spiral arrangement, in form like
