EXAMINATION 21 



which is well-nigh incurable. Cross-firing and 

 blistering occasionally set matters right, but 

 usually the lameness returns again. Eing-bone 

 is present much more frequently in the hind 

 extremities than the fore. From the front of 

 the coronet the fingers are run round to the 

 sides, carefully manipulating the parts here 

 with pressure, to determine if side-bones are 

 present. 



Overreach. — In examining the coronet, look 

 carefully for an overreach, which is a tread upon 

 the back part of the coronet of the fore-foot from 

 the shoe of the hind-foot. 



Tread. — Treads are abrasions or wounds 

 caused by the treading of one foot on to the 

 coronet of the other. These are frequently the 

 cause of lameness in a horse when bad, but on 

 heahng them up they give no more trouble as a 

 rule, unless the parts are badly injured, forming 

 a quittor, and are therefore in themselves scarcely 

 to be considered as an unsoundness. If the tread 

 is a bad one, and a quittor has been formed, then, 

 as a rule, a long time elapses before the animal 

 becomes sound again in his action.
