majority of hind leg lameness, the hock is the true situation. This 

 fact is not apparent to the non-professional person, as the hock, 

 while diseased, does not swell so often as other portions of the 

 body or legs when diseased. Bog or blood spavin and thorough- 

 pin, a blind man can almost see. With these exceptions, I say, 

 hock-joint lameness, in the majority of cases, is charged to the hip 

 or somewhere else, simply because persons fail to see any pecu- 

 liarity, even when pointed out to them. (See String-halt.) 



Sprain of the hock-joint is to be treated with cold water cloths, 

 for a few days, and the application of the foIlQwing, once every 

 second day, for a week, with friction or rubbing : Oil of turpen- 

 tine ; oil of olives ; equal parts. Mix. This is a simple, cheaR 

 and good liniment, and will answer every purpose. 



Rupture of the internal and external lateral or side ligaments 

 of the hock-joint is occasionally seen, and is caused by a violent 

 slip. The rupture is at once recognized by the logs of power of 

 the horse over the leg below the joint ; but can stand on the leg, 

 as if it were sound, and there is little or no swelling — which pe- 

 culiarities serve to show the difference between a broken bone of 

 the leg and the ruptured ligaments of a joint. (See Ligaments.) 

 The cure is accomplished by absolute and entire rest, with occa- 

 sional friction with the turpentine liniment, just mentioned above. 

 Be assured of the complete union of the ligaments — which will 

 take place when the horse can bend and properly use the leg — be- 

 fore exercise or work be exacted. 



Hooks in the Eyes. — This is a term in use by country folks 

 when referring to the peculiar action of the membrana irictatans in 

 cases of locked-jaw (which see). Many persons have advised 

 that these useful membranes should be cut out. Nothing could 

 be further wrong than this ; for it is merely the effect of a cause. 

 Rather remove the cause, or cure the locked-jaw, and the protrud- 

 ing of the hook or horns will cease. This is the only true plan 

 to adopt.
