BRADYPUS DIDACTYLUS. 177 



on the convex surface ; it adheres to the under surface of the large lobe 

 of the liver. The ductus cysticus, in Dr. Blane's, passed down through 

 the substance of the liver and emerged at the aorta like the ductus 

 hepaticus ; it then joined the ductus communis, and entered the duo- 

 denum about an inch from the pylorus. 



The pancreas lies in the root of the mesentery ; its left end gets loose 

 in the posterior part of the epiploon, or what may be called the attach- 

 ment of the last cavity of the stomach to the root of the mesentery upon 

 the right : as the pancreas passes along the mesoduodenum it becomes 

 smaller and its duct enters the duodenum about 4 inches from the 

 pylorus. 



The stomach consists of different pouches: the first or large one is 

 situated on the left ; the last cavity passes to the right, as the last part 

 of the stomach does in common. The first cavity of the stomach adheres 

 by a pretty broad surface to the diaphragm. 



The epiploon is narrow, hardly making a doubling, and is attached to 

 the last cavity of the stomach forwards, and to the root of the mesentery 

 backwards. The spleen is almost round, flat, and thin, and is pretty 

 closely attached to the second cavity of the stomach. The mesentery 

 is long from the upper to the lower end, and is narrow from side to 

 side, or from right to left. 



The small guts are immediately attached to the right of the mesen- 

 tery : the intestine passes down the right side and is much convoluted, 

 the turns being short ; it gradually twists towards the left behind the 

 mesentery, and then forwards as coming to the right again; when it 

 forms what I shall call a colon without a caecum. The mesentery is so 

 loose as to be twisted ; therefore the true position of the intestines is 

 not to be ascertained. 



The colon may be said to begin at the lower end of the mesentery, or 

 at least the gut almost immediately becomes large here ; it takes a turn 

 in the contrary direction, back to the left along the opposite edge of 

 the mesentery, and then passes down the loins to the anus 1 . The faeces 

 were a uniform gelatinous mass. There are three valvular parts in 

 the intestinal canal ; the first at the beginning of the colon, the next 

 about its middle, and the last near the anus, or in the pelvis ; after 

 this the gut becomes very large, like a fowl's. 



. The kidneys lie low in the loins ; each has only one oblong mammilla. 

 The capsulae renales are long and large bodies, and are more in the 

 usual place of the kidneys 2 ; but this was a foetus. [Added note : (In 

 another, about half-grown, it was the same.)]
