Ic. Lymph-corpuscle. 
v. Blood-vessels. 
In the upper part of the chyle-vessel, the reticulum surrounding the cells of 
the villus is seen to be continued between the endothelial cells of the chyle- 
vessel. 
The cells of the upper part of the villus are larger than those in the 
lower part. 
In the lower part of the figure the reticulum can be traced from the chyle- 
vessel to the border of the villus. 
Big. 22. Camera Lucid a : obj. 7, X 450 — oc. hi., obj. 9. 
Section of the lower part of a villus, from the small intestine of a hedgehog. 
Z. Central chyle-vessel, containing a little granular matter. 
m. A small band of muscles ; they are in contiguity with the wall of 
the chyle-vessel. 
The reticulum is attached to the wall of the chyle-vessel, and passes between 
the cells of the villus. 
Bigs. 23, 24, & 25. Brom the villi of a hedgehog killed during absorption of fat. The 
intestine was hardened in osmic acid. 
Big. 23. Oc. hi., obj. 11 immersion, X850. 
Surface view of epithelium, teased, and treated with caustic potash. 
The fat is seen as small black particles between the epithelial cells. The 
clear spaces are the openings of goblet-cells. 
Big. 24. Camera Lucida : obj. 8, x600 — oc. hi., obj. 9. 
Section of a villus. The fat is seen as small black granules in a reticulum. 
Big. 25. Camera Lucida: obj. 7, x450 — oc. hi., obj. 8. 
Section of the lower part of a villus. 
Z. Chyle-vessel. 
In the upper part of the figure the fat-particles in the chyle-vessel have 
run together. 
The fat-particles are seen in the reticulum of the villus. 
Big. 26. Oc. hi., obj. 2, x45. 
Vertical section of the pyloric end of the stomach of a dog. 
mm. Muscularis mucosae. 
d. Duct of the tubes. 
ct. Proper glands, or coiled tubes. 
Some of the plicae villosae (jp) are seen to be shorter than the others ; the 
epithelium on the sides of the shorter ones is folded. 
Big. 27. Camera Lucida: obj. 5, x300 — oc. hi. , obj. 7. 
Epithelium covering one of the villus-like processes of a rabbit’s colon. 
The intestine had been stained in gold and hardened in chromic acid.
