On Sprains. 



THESE next demand our consideration, as the 

 horse, from the great exertion he is frequently 

 obliged to undergo, is veiy liable to receive in- 

 jury in some of his joints. 



It is well known, that external force may be 

 applied to a joint, so as greatly to strain and in- 

 jure its ligaments, without absolute dislocation 

 having taken place. 



This, in general, is attended with extravasation 

 and swelling, the cellular membrane becoming dis- 

 tended, from an increased secretion of synovia- 

 especially where the capsular ligament is loose; as 

 in the joint of the hock or pastern. This is often 

 succeeded by inflammation, and lofs of motion of 

 the joint ; at least there is considerable difficulty 

 in performing it ; these parts, before nearly insen- 

 sible, now becoming highly sensible and painful. 



When the sprain is recent, bandages impreg- 

 nated with the following mixture, may eh%ct a 

 cure : 



Take sugar of lead, half an ounce ; the best 

 vinegar, one pint; rectitied spirits of wine, 

 four ounces : mix and shake them well to- 

 gether for use.
