J 14 HOW TO BUY A HORSE. 



all. It is sometimes curable by firing and blistering, 

 sometimes utterly incurable. It is always an absolute 

 cause for not purcbasing any borse; but not always an 

 absolute cause for selling an otherwise good borse. We 

 ou3e drove a grey grandson of Messenger, for five years, 

 who bad a very large bone spavin in tbe very worst place. 

 He invariably took his three first steps from a stationary 

 position, however momentary the duration of the time he 

 had been at rest, like a dead-lame horse, but then went as 

 sound as any other horse in the world, until he again stood 

 Btill. No day was too long for him, nor was every day in 

 a month too often. But, after all, he was not the rule, but 

 the exception which proves the rule. 



Bog spavin is the extravasation of the synovial fluid, 

 nrhich lubricates the joint, and its collection in a sac in the 

 mward and lower anterior portion of the hock joint, some- 

 what within and before the point at which the bone spavin 

 occurs. It may be seen partially in profile, but can be felt 

 readily by pressure of the hand, under which it fluctuates. 



Blood spavin is a similar extravasation of arterial blood 

 and formation, nearly in the same place, of a sort of 

 aneurismal sac. It is detected as before, and may be dis- 

 tinguished from the bog spavin by the fact that it pulsates. 

 Both these spavins are incurable under any ordinary treat- 

 ment ; the former absolutely so. It is possible that tying 

 the artery might reduce the latter, but we are not aware 

 that the operation has ever been tried. 



Tlwroughpin is a similar extravasation of the synovial 

 fluid, and the formation of a sac, running between the 

 bunes of the hock joint, not from the fix nt backward, but 

 across the joint, fi-om side to side. It can be easily de- 

 tected by the fingers, under the pressure of which the 

 fluid can be felt to ebb and flow from side to «ido. 

 Tboroughpin, like the kindred spavins, is ii curable. It
