short broad cells divide longitudinally, and form groups of two or three, 

 or even more cells, which the author calls " epithelial buds." 



4. A reticulum among the epithelial cells is described : it is found to 

 be very delicate, and does not extend to the surface. 



5. The membrana propria is found to be composed of large cells. 



6. The muscle-endings in the plicae villosse are similar to those in the 

 colon of the rabbit, already described. 



7. Perivascular spaces are found in the upper part of the plica? 

 villosae ; these spaces are bordered by endothelial cells : the membrana 

 propria forms the upper wall of the space. 



8. The proper gland-tubes. — A fine reticulum is described as occur- 

 ring among the epithelium of these glands. The nuclei are found usually 

 as flattened disks lying at the base of the cells. The nuclei are, however, 

 during digestion occasionally found to be spherical in form. A third 

 kind of nucleus was also found, which was possibly intermediate between 

 the two other forms. 



Chapter III. describes the mucous membrane at the point of transition 

 between the stomach and intestine : after giving a short history of the 

 subject, it is shown that in many animals Brunner's glands are only the 

 continuation of the proper glands of the stomach. Part of the proper 

 gland-tubes break through the muscularis mucosae, and then the glands 

 are situated in the mucosa and submucosa ; finally they are only found 

 in the submucosa. 



The mucosa at the point of transition was found to contain lymphoid 

 follicles in very varying amount, the mucosa being in some animals 

 almost free from them, and in others composed in a great measure 

 of lymphatic tissue. This latter condition was found to be the case in 

 dogs which were kept on a very reduced diet.
