532 DISCRIMINATION NECESSARY. [BOOK III. 



after the corn has heen pared and treated with butter 

 of antimony. Tar is then a very desirable appli- 

 cation, or Friars balsam ; and if inflammation is 

 again discovered, poultice the foot once more. 

 Fire is applied by some, but the hoof is per- 

 manently injured by the actual cautery ; and what- 

 ever good is achieved is thus counterbalanced by 

 the evil. Vitriolic acid mixed, carefully, with tar, 

 in the proportion of one-tenth of the former to nine- 

 tenths of the latter, will promote the absorption 

 upon which the cure depends. 



But in some desperate bad cases, the matter has 

 already formed within, most offensively, and dis- 

 charges at the coronet by means of that curious 

 process of nature which we described at a preceding 

 page, as affording the coronet the material for 

 forming new horn to supply the wear and tear of 

 the hoof. Upon paring away the horny sole, which 

 now becomes necessary, the offensive matter will be 

 found to have spread itself underneath the sensible 

 sole, which will ooze forth and give immediate re- 

 lief to the coronet. Let so much of the horny sole 

 as lies loose from the sensible sole be pared away, 

 and a dressing of tar, or of Friar's balsam, be ap- 

 plied as before directed; and if inflammation is 

 again discovered, apply a bread poultice ; should 

 the growth of horn be found too luxuriant, discon- 

 tinue the tar.
