 This roughness of the hock-joint, however, will 

 generally be found to be accompanied by the 

 same general characteristics in all the articulations 

 of the individual, and a truly " coarse hock " is 

 seldom or never present in an animal of otherwise 

 fine-grained quality ; nor is an animal likely to 

 have one coarse hock, and one smooth one ; in 

 either of these cases any deviation from smooth-

 Suspicion in any case may be made certainty by 

 driving the suspect until thoroughly warmed up, 

 leaving him in his stall for an hour or two, and 

 then re-examining him (watching especially how 

 he backs out of the stall) , and turning him sharply 

 both ways before trotting him, slowly, to halter, 

 and with his head loose. You may also hold his 

 foot well up against the stomach for a few
