splint is most apt to interfere with the natural 

 action, or produce lameness. In all cases this 

 disease commences in the Periosteum the vascu- 

 lar membrane covering the bone. Over exertion, 

 and concussion, in badly shaped limbs, drives to 

 it an over supply of blood, the parts become hot 

 arid tender, and lymph is exuded from the in- 

 flamed vessels, and gradually converted into 

 bone. 



TREATMENT. 



In the beginning, while there is much fever, 

 keep well wet with the following preparation: 

 Sugar of Lead 1 oz., dissolved in \ qt. of water, 

 and an addition of 1 pint of Vinegar, by means 

 of cloths saturated in foregoing solution, or if 

 handy to stream or pool of water, let the horse 

 frequently stand an hour at a time therein. 

 Leave him idle 20 to 30 days. When the heat 

 leaves the limb apply the fly -blistering prepara- 

 tion of the shops, or ointment of Binoiodide of 

 Mercury, or the hot iron. The foregoing reme- 

 dies condense and harden the bony deposit, but 

 do not remove it. Union shortly takes place be- 

 tween the large and small splint bones; swelling 

 becomes solid; the lameness disappears, and the 

 splint still remains, but scarcely ever produces 

 any subsequent blemish or inconvenience.
