Bone Spavin. 



This disease generally attacks diseased horses, and is 

 situated on the upper end of the shank bone of the hind 

 leg, either below or in the middle of the hock joint. 

 Horses with their hind-legs much bent at the hock, and 

 termed cow-hocked, are more subject to this affection, 

 since the stress is increased upon that part by its 

 angularity, which, if not speedily removed, may prove 

 incurable. In the inflammatory state, or during the 

 first attack of the bone spavin, the lameness will disap- 

 pear for a short time after the horse has been exercised, 

 and by this circumstance, the bone spavin is distinguished 

 from lameness in any other part of the limb. 



Remedies. — Spavins can only be successfully treated, 

 if at all, by blisters frequently repeated, which may 

 induce an absorption of the long deposit ; when this fails, 

 then liave recourse to firing, and if firing proves 

 ineffectual, no other means is likely to succeed. The 

 animal to have a diuretic ball every week after being 

 fired for a month, composed as follows : —

Bog Spavin. 



This disease is more frequent than the blood spavin, 

 and generally proceeds from similar causes. 



Symptoms. — Nearly the same symptoms are generally 

 apparent in this case as the preceding. It is attended 

 with a slight inflammation, which causes enoysted 

 swelling or enlargement of the capsules or membraneous 

 bags, that contain and afford the synonoira that lubricates 

 the joints at the upper and inner side of the hock.
