MUCOUS FOLLICLES. 215 



light color. The villi upon its free surface are highly devel- 

 oped, being long, slender, often compound, and approximat- 

 ing in appearance, when simple, very much to the villi of 

 the small intestines. The tubules of the mucous membrane, 

 T i T of an inch in diameter, run vertically through its whole 

 thickness and terminate at various depths. The shorter ones 

 are without branches, nearly straight, and terminate by sim- 

 ple rounded extremities. The longer ones give off several 

 lateral branches near their lower extremity, the upper 

 branches being longer, the lower ones shorter, the whole 

 group collected into a little mass or lobule. These tubes are 

 lined with epithelial cells, mostly of a cylindrical form, but 

 of very small size, closely packed, and evidently glandular in 

 character. 



" In the neighborhood of the cardia, the mucous mem- 

 brane is quite thin and pale, without any well-developed vil- 

 lous projections. In the superficial portion, the tubules are 

 very wide cylinders, lined with large, clear, well-defined cells 

 of cylinder-epithelium, branching below usually into two 

 smaller tubes, also lined with cylinder-epithelium. These 

 tubes become still further reduced in size until they are a lit- 

 tle narrower than the tubules of the pyloric portion, when they 

 become lined with small glandular epithelial cells, and ter- 

 minate below in rounded extremities. The secreting tubules 

 of this portion of the stomach are much shorter than those 

 of the pyloric portion. 



" In the middle portion of the stomach, especially along 

 the great curvature, the mucous membrane is considerably 

 thicker than elsewhere and is of a dark-red color. The villi 

 upon its surface are perfectly distinct, though not so long 

 and slender as in the pyloric portion. The gastric tubules 

 are much longer than in any other part, and more closely 

 bound together at the bottom, so that they are separated 

 with much greater difficulty. They are rather wider than 

 the other secreting tubules, and contain, besides the ordi- 

 nary smaller epithelium, an abundance of large, rounded,.
