the anatomy of the indian elephant. 59 



Liver. 



The liver is divided by the suspensory fissure into two lobes, 

 of which the right is the larger. There is no gall-bladder, but 

 the ductus cholsedocus expands in the wall of the duodenum 

 into a sacculated pouch, which receives also the secretion of the 

 pancreas. The termination of the duct projects slightly into the 

 small intestine, and is surrounded by a sphincter. 



Pancreas. 



The pancreas of the elephant differs little from that of most 

 mammals ; it does not reach the spleen. 



Spleen. 



The spleen is long and flat, broader in the centre than else- 

 where, and occupies its usual position. 



MALE GEI^EEATIVE ORGAIs^S. 



Dr Morrison Watson's account of the male organs of the ele- 

 phant,^ evidently founded upon a careful dissection, but neglecting 

 no advantage which is to be derived from the comparison of 

 earlier descriptions, is probably the best accessible, and may be 

 consulted for fuller details than are here given. We extract 

 from it most of the particulars which follow :— 



Testis. 



The testis is nearly globular, and lies below the posterior ex- 

 tremity of the kidney. It is entirely invested by peritoneum, 

 except at the upper and external margin where the vessels enter. 

 The epididymis lies on its outer side. The veins leaving the 

 gland are remarkable for their number, large size, and free com- 

 munications. Ten or twelve vasa efferentia pass into the 

 epididymis, which is continued without interruption or flexure 

 into the vas deferens. With the exception of the last five 

 inches, the vas deferens is convoluted in the whole of its course, 

 and attached to the superior wall of the abdomen by a double
