126 THE HOUSE. 



Horses laboring under a liability to this disease are, on 

 some occasions, deprived instantaneously of the use of 

 the part so affected; as, for example, a horse will become 

 paralyzed in his leg while he is in action. I have known 

 horses, while trotting or galloping rapidly, to be deprived 

 momentarily of the use of a leg to the great risk of the 

 rider, and, after a few moments, to recover the use as 

 suddenly, and proceed as well as ever, until again 

 attacked. A horse liable to paralysis is UNSOUND. 



Until this disease has endured long enough to shrink 

 or partially wither the muscles, it is not easily detected 

 by those who are not conversant with the symptoms. 



Paralysis must not be associated with " shrunk mus- 

 cles " when the muscles are shrunk from other causes. 



HUMORS. 



Humor is a term applied to swelling of the legs and 

 other parts of the horse, and to small spots on the body 

 which denote a want of medicine or bleeding. When 

 humor arises from weakness or overwork, tonics should 

 be applied occasionally, but as they are not popularly 

 understood by the term medicine, it is right they should 

 be mentioned to prevent the substitution of depletents. 



A horse while thus troubled is UNSOUND. 



When the effect of the medical treatment is over, and 

 the indication of its necessity removed, he is again SOUND. 



See article on " Surfeit." 



CLAMBERING. 



The high and short stepping of a horse is called 

 clambering.
