the blood is still on one side and the cavity on the other, 

 but as a result of the dift'erence of position, the villus is 

 adapted to the absorption of products which surround 

 it in the chyle, while the gland is suited rather for the 

 work of secretion. There is a considerable difference in 



the histological character 

 of the cells from different 

 parts of the mucous coat. 

 Fig. 4 shows a section 

 in the depth of the gland, 

 its lumen is large, there 

 are no cover cells, and 

 the gland cells are higher 

 than broad, at the upper 

 part of the drawing, a 

 surface view of the tube 

 is represented, where the 

 section passes out of the 

 plane of the lumen. 



Some of the cells of 

 the gland are swollen and 

 empty, these are not so 

 numerous as in the crypts 

 of the large intestine.

 supposed to be mucous cells which have discharged their 

 contents. The cells of the villus are shown in figs. 3, 4, 

 and 5. In the first a small part of the villus with eight 

 adjoining cells are shown, one of these is a goblet cell, 

 in 5 a single cell isolated from the rest by maceration, 

 in an animal killed soon after a meal containing a large 

 amount of fat. The fat drops have been demonstrated 

 by staining with osmic acid, and are seen to be inside 

 the cell. In fig. 4, a surface view showing a goblet cell 

 ai^d several surrounding cells of the villus is given. The
