; BLISTEES, OR VESICANTS. 



Blisters are applications which inflame the skin, and produce 

 a secretion of scrum between the cutis and cuticle, by which the 

 latter is raised in the form of small bladders; but in consequence 

 of the presence of the hair, these are very imperfectly seen in th'e 

 horse. They consist oftwo kinds — one, used for the sake of cottn. 

 ter- irritation, by which the original disease is lessened, in conse- 

 quence of the establishment of this irritation at a short distance 

 from it; the other, commonly called "sweating" in veterinary sur- 

 gery, by which a discharge is obtained from the vessels of the part 

 itself, which are in that way relieved and unloaded. There is aW 

 a subsequent process of absorption in consequence of the peculiar 

 stimulus applied.
