16 SOUNDNESS IN HORSES. 



removed then and there by the act of coughing, as, for 

 instance, in the case of a particle of dust going "the 

 wrong way," this act of coughing should be regarded 

 as the performance of a natural function, and not as 

 an unsoundness. But, if the irritation remains to an 

 extent sufficient to cause the animal to cough, more or 

 less continuously, such a horse would be unsound; the 

 persistence of the irritation being the cause of the 

 unsoundness. Although the irritation, as in teething, 

 may be a symptom of a healthy and natural process, it 

 is not the less, on that account, detrimental to the 

 animal's usefulness. 



Curb. — This is an unsoundness, whether or not it causes 

 lameness. Practically speaking, its existence, after the 

 inflammation has entirely subsided, is, generally, of but 

 little moment ; except in animals which, like troop- 

 horses, are " put on their haunches," a great deal. 



Eye, diseases of the. — For instance, amaurosis, glaucoma, 

 ophthalmia (simple and periodic), cataract, and others. 



Docking, wound hy. — A horse recently docked should 

 not be passed sound until the wound has healed; for 

 tetanus is liable to follow this operation. 



Elephantiasis. — This is a result of lymphangitis. 



False quarter. 



Farcy. 



Fistula of the parotid gland. 



Fistulous withers.
