CHRONIC COUGH. 465 



of a deep, hollow nature, differing materially from the loud sonorous 

 sound of a healthy cough. 



It is often associated with other diseases of the chest, as broken 

 wind, thick wind, etc. The cough is generally most severe in the 

 morning or after meals, and is always aggravated by gross feeding. 

 In many cases chronic cough interferes but little with a horse's use- 

 fulness, especially if he is used for ordinary farm work ; but it must be 

 considered an unsoundness. 



Treatment. — If the horse has been affected for some time, treat- 

 ment is generally very unsatisfactory, and must be more of a pallia- 

 tive than a remedial nature. If only recently, treatment may be 

 undertaken with better chances of success. Give the cough ball as 

 recommended for laryngitis, and apply the following liquid blister, 

 or any good counter-irritant, externally, and in some cases great 

 benefit will attend the use of setons. / 



Olive-oil, oil of turpentine, aqua ammonia, equal parts. 



To be shaken well, and rubbed on with the hand. 



If occurring from intestinal disorder, the treatment of course 

 must be directed to the proper seat. The medicinal treatment is 

 greatly assisted by feeding the animal properly and regularly, giving 

 small quantities of food at a time ; carrots in winter, and green food 

 jn summer should be given. Feeding nice clean corn-stalks is much 

 better than hay ; if hay is fed, it should be bright and clean, or the 

 dust shaken out of it, and dampened a little, and of this only a lim- 

 ited quantity should be given. If a greedy eater, either remove 

 from his reach the bedding, which he will be likely to eat, or 'put on 

 a muzzle. The following are also excellent cough remedies : —
