DEVELOPMENT OF THE LAEGE INTESTINE 225 



surface epithelium and are then entirely surrounded by connec- 

 tive tissue. They later disappear by degeneration and absorp- 

 tion. Lymphoid nodules are found in abundance in the vermi- 

 form process at birth, but the cysts never lie in the centers of 

 them. 



10. Epithelial cysts are also found in the mucosa of the rectum. 

 They are in many ways similar to those found in the vermiform 

 process, but differ from them in that they are not so deeply 

 seated in the tunica propria, are seldom entirely detached from 

 the surface epithelium, and disappear not by degeneration and 

 absorption, but by breaking through into the intestinal lumen. 



11. Distention of the large intestine, due to the accumulation 

 of meconium, brings about marked changes in the form of the 

 mucosa. It reduces its thickness, broadens and shortens both 

 villi and glands, and causes them to become spread apart.
