 and all the chyle occasionally obtained 

 from the bowels, are conveyed into the

 with nutriment, and occasionally taint it 

 with infection.

 parts of the body, without entering into 

 any detailed description of their particu- 

 lar distribution. We may just observe, 

 that the course of thes vessels, and their 

 entrance into glands,become occasionally 

 demonstrated in disease. When irritated 

 by any local mischief, they form red 

 streaks, manifest on the surface of the 

 body : and the irritating or poisonous na-

 Thus the glands in the groin swell from 

 the absorption of venereal matter ; those- 

 in the axilla become affected in cancer, 

 and in the inoculation for the small pox.
