CHAP. III.] OVER-FEEDING, ITS EFFECTS. 399 



the full feeders of every genus of created beings. 

 If, during this full and over-replenished state of 

 the alimentary canal, and its then active state of 

 lactification (or making of new blood), a sudden 

 check be put upon the said process, by drinking 

 cold water for example, what happens but the rapid 

 propulsion of some part of the blood through the 

 arteries, whilst the mouths of the offended lacteals 

 close up for a period, and the blood, already filling 

 the capillary vessels of the surface, becomes ex-

 feit, the second is the more loathed mange, both 

 having but one common origin. They are of the 

 class of tubercular diseases, spoken of higher up, as 

 partaking of glanders, are akin to grease, and to 

 other accessions of matter on the surface, differing 

 only as to situation, and, like the grease, require 

 that we should promote absorption and the applica-

The cause of surfeit is thus distinctly met by the 

 means of cure. The symptoms, however, frequently 

 announce the disorder that has taken place within 

 but a few minutes ere they subside again, to the
