DISEASES OF THE FEET.

Treatment. — Kemove all the diseased parts and promote the 

 growth of horn bv blisters, the cantharides blister being the best 

 in this disease — one part of cantharides to ten of lard. The shoe 

 clips should be removed and a bar shoe used. This condition is 

 an unsoundness in all its stages. 



CORNS. 



A corn is the result of a bruise, involving the stmctvire of the 

 bars in the angle of the heels; occurring in the fore feet and 

 almost invariably in the inside 

 heel, and caused by bad shoeing. 

 A corn consists of a bruise, and 

 extravasation of blood, from rup- 

 ture of the small blood vessels, 

 which insinuates itself into horny 

 texture and gives it the charac- 

 teristic red appearance. It may 

 terminate in suppuration, partial 

 necrosis, horn tumor, or forma- 

 tion of bony spicula of the pedal 

 bone. A corn constitute an un- 

 soundness in all its stages. 



Treatmext. — R e m o v e the 

 shoe, and having decided that a corn is present, pare it down 

 nicely. If the corn has festered, give exit to the pus. Poul- 

 tice the foot for a few days, when the shoe recommended by 

 Professor Williams, previously referred to, should be applied. 

 This shoe docs not reach the seat of corn. If animals were 

 shod with such shoes, corns would be unknown. A round 

 shoe may be used with good results. Sometimes a fungoid 

 growth springs up when suppuration has occurred. In such 

 a case nitrate of silver should be applied, or corrosive subli- 

 mate. "Where the corn has not suppurated, it may be dressed 

 wltli pure carbolic acid.
