252 Dr. Schreibers’s Description of 
terminating in the rectum, which is very strong, and wider 
towards the anus. 
The internal surface of the stomach, towards the bowels, is 
very much wrinkled longitudinally, forming a perfect pylorus. 
These wrinkles continue throughout the whole length of the 
intestinal canal, and, in the large intestines, are very strong, 
forming serrated plicse. 
The stomach and intestines are very loose in the cavity, 
being connected with the neighbouring parts only by thin 
membranes. The rectum, however, at its termination, is firmly 
connected with the kidney underneath, and attached above to the 
ossa pubis. A little above this is a narrow viscus, about half an

opens into the lower end of the rectum, by means of a short 
narrow canal, through which I could pass a thin bristle. By 
its situation and structure, I suppose it to be the uterus ; though 
I observed it in every one of the dissected specimens. 
The spleen is flat and narrow, about one inch and a half 
long, fastened to the back of the stomach on the left, and also 
to the pancreas, with which it seems to be farther connected by

appearance. 
The pancreas is narrow, and about one inch long; it is 
attached to the back of the duodenum, and also to the gall- 
bladder. 
The mesentery is a thin membrane, fastened strongly to the 
back of the intestinal canal on one side, and to the neighbour-
