CAVIA PORCELLUS. 209 



that veiy thin. This duct comes in contact with the duodenum almost 

 close to the pylorus ; then makes a turn and passes with the gut for 

 more than one-third of an inch, where it becomes larger, and then it 

 enters the gut at the swell of that gut, as was mentioned. This looks 

 as if this duct must make a turn somewhere, as it did not do it at the 

 gall-bladder. The bile is very thin and almost transparent, and looks 

 a good deal like brandy or rum. 



The liver is attached to the diaphragm by two ligaments, the falx and 

 the transverse : the falx is very thin ; so is the transverse one ; and this 

 is pretty broad through its whole length ; so that here it deserves the 

 name of ligament, and perhaps this name was at first taken from the 

 brutes. 



The pancreas is much, as in other brutes, only the small one passes 

 into the doubling of the duodenum, something similar to that of a fowl, 

 as this gut makes a fold, as in a fowL The large one is very long, not 

 attached to the spleen, but passes a little way into the epiploon. Its 

 ducts enter the duodenum after the duodenum has made that sort of 

 doubling upon itself something like a fowl's. This entrance is about 

 five inches from the pylorus. The spleen is very small and short, not 

 so long as is common in brutes. 



The kidneys are pretty round and thick, and conglobate ; the right is 

 higher than the left : the capsula renalis is of two colours, viz. a yellow 

 on the outside, and a darker on the inside \ 



The testes are veiy large, about the size of the kidneys ; the size of 

 which is in the usual proportion to the size of the animal. The testes 

 are placed within the abdomen, in every respect as in the hedge-hog, 

 porcupine, bat, squirrel: the cremaster is the same. At the part 

 where the cremaster seems to turn, the parts are much more loose, 

 and the testicle seems as if it could be half pushed out of the belly. 

 The testicles are not so oval as in the human : their attachment to the 

 psoas is by a broad doubling of peritoneum, so that they are very loose, 

 much like the [testes in the human] foetus when they are going out of 

 the abdomen. The epididymis begins as usual ; it is very small as it 

 passes down on the testicle, but becomes very thick at the lower end. The 

 vasa deferentia pass immediately into the pelvis, are wider than in the 

 human, and were filled with a very white semen like very white cream ; 

 they pass behind the bladder, and do not communicate with the ducts of 

 the vesiculse seminales. The vesiculse seminales are two long tubes, 

 about 4 inches in length, and a quarter of an inch in diameter at their 

 thick ends, but become much smaller at their points ; they lie loose in
