by the formation and discharge of pus. The parts next 

 lose their pliancy, become hard and rigid. The skin 



cracks, by which deep fis- 

 sures are formed, from 

 which an offensive dis- 

 charge constantly flows ; 

 while ulceration goes on 

 beneath, fungoid granula- 

 tions are luxuriant and plen- 

 tiful, forming what are com- 

 monly known as "grapes." 

 The disease now assumes 

 chronic and permanent cha- 

 racters, rendering the ani- 

 mal not only offensive, but 

 dangerous, as none can tell 

 how soon the disease may 

 terminate in farcy. The 

 disease is common to 

 coarsely bred horses, but 

 poverty, dirt, and improper treatment are known among 

 the causes when it appears in animals of higher breed. 



Treatment. — Poultices at first; when the parts are 

 thoroughly cleansed, solutions of salts of zinc, copper, &c, 

 may be applied several times daily (see "Astringents"). 

 The remedies should be used alternately, which is pre- 

 ferable to the persistent application of one. The grapes 

 should be touched with caustic potash, solid chloride of 

 zinc, &c, or they may be shorn off by means of the actual 

 cautery, the animal being properly secured. Internal 

 remedies are of vital importance. Tonics, No. 2, to 

 which 2 drms. each of resin and ground ginger have 

 been added, should be given twice daily. Fowler's 

 solution of arsenic, in \-oz. doses, should be sprinkled 

 over the dry manger food twice a day, or put into the 

 drinking water. 



Boils, or Carbuncles. — A boil is the result of inflam- 

 mation of the deepest layer of the true skin, together with 

 the cellular tissue beneath. It is a circumscribed swelling, 

 at first of small dimensions, around which inflammation
