ANATOMY OF THE SONDAIC EHINOCEHOS. 191 



6 inches from the greater curvature of the stomach. It followed this curvature, and 

 ended about its middle by joining with the gastro-epiploic branch of the splenic. The 

 artery on its way gave off numerous and regular branches to both surfaces of the right 

 half of the stomach, in the vicinity of the greater curve, and supplied at the same time 

 more than one half of the great omentum. 



The splenic arteiy (PL XXXVl. fig. 1) adopted a curved course, running first from 

 right to left and then from left to right. On reaching the smaller extremity of the 

 spleen the artery ran in the anterior layer of the gastro-splenic omentum at a, distance 

 of about 2 inches from the viscus itself. From its concave side it gave off numerous 

 vessels (the vasa brevia) that supplied both surfaces of the cardiac ends of the stomach, 

 anastomosing at some little distance from the greater curvature with the anterior and 

 posterior gastric arteries. From its convex side branches arose to supply the spleen. 

 These reached the viscus by running in the anterior layer of the gastro-splenic omentum ; 

 some on reaching the capsule at once entered the spleen, while others were continued 

 across its gastric surface until the attachment of the posterior layer of the gastro-splenic 

 omentum was reached. At this point they formed arches whence small offshoots were 

 derived for the supply of the hinder layer of the omentum. These vessels in their ' 

 passage across the spleen gave oflF numerous branches to its substance. 



The Ccecum and Colon. (Plate XXXIV.) 



In all general points the disposition of the colon was identical with that described by 

 Professor Garrod as occurring in the Sumatran Rhinoceros. The caecum was conical in 

 shape, and its outline very closely agreed with Professor Garrod's figure ; it was median 

 in position, its long axis was directed backwards and to the left, and its apex occupied 

 the pelvis. 



The large intestine immediately beyond the csecum was thrown into a considerable 

 loop, just as is the case in the Horse. This loop was first of all directed transversely to 

 the left, but soon becoming bent upon itself turned backwards and upwards. The 

 head of the loop was situated in the left iliac region, while the root of its returning 

 limb was found in the right hypochondriac region. It was the returning segment of 

 the colic loop that formed so conspicuous a feature in the abdomen when the viscera 

 were first viewed in situ (woodcut, p. 185, Col). 



From the right hypochondriac region the colon passed transversely across the abdo- 

 men fi-om right to left, and, having reached the left side of the body, it passed almost 

 directly backwards to form the descending colon. This transverse portion of the bowel 

 was hidden by the root of the colic loop, while the descending colon was almost entirely 

 hidden from view by the coils of the small intestine. The relations that the ctecum 

 bore to the colic loop would appear to have difiered somewhat from those observed in 

 the Sumatran species. 



The base of the cscum covered entirely the inferior aspect of the root of the colic
