392 Mr. Home's and Mr. Menzies' Description 
sembling small leaves upon the branch of a shrub. The little 
pancreas puts on the same appearance, covering the whole me- 
so-duodenum, which is unusually broad. The duct of the pan- 
creas is of the ordinary size, it opens into the duodenum by a 
separate orifice \\ inch from the pylorus. 
In the common otter the pancreas has not this unusual sub- 
divided appearance, and the duct opens by a common orifice 
with those of the liver into the duodenum. 
The receptaculum chyli is an oval bag, -|ths of an inch broad, 
from which two trunks go off to form the thoracic duct, each 
of them about ith of an inch in diameter; these anastomose 
frequently in their course, so that there are always two, some- 
times three, and even four trunks, running parallel to each 
other ; the thoracic duct is 8 inches in length. 
The kidneys are conglomerated, six inches long, and three

The urinary bladder is pendulous and pyramidal, and the 
ureters open into it very near each other at the lower pos- 
terior part. 
The testicles are situated under the external skin on each 
side of the sheath of the penis, but have no pendulous scrotum. 
They are small, flat, and oval. The tunica vaginalis commu- 
nicates with the cavity of the abdomen. The cremasier muscle 
is very strong. 
The vasa deferentia, as they pass behind the bladder, be- 
come a little convoluted, and open into the urethra at the 
caput gallinaginis. 
The penis, in the relaxed state, is 8 inches long, the bone 
6 inches. The corpora cavernosa are small, but strong in their 
coats. The bone near its anterior end appears to be covered
