146 The Horse Farrier. 



for the remainder of his life. This disease is usually con- 

 sidered contagious, but we are not clear on this point, but 

 it will be well to separate the patient from healthy ani- 

 mals. This we would recommend in ali cases of catarrhal 

 affection. 



Symptoms. — It is is generally preceded by cough with 

 a discharge from the nostrils of a yellowish color, mixed 

 with pus, generally without smell, the membrane of the 

 nose intensely red, a swelling under the throat which in- 

 creases, accompanied by a fever — a disinclination to eat 

 — a considerable thirst, but after a gulp or two the horse 

 ceases to drink. In attempting to swallow, a convulsive 

 cough comes on, which threatens to suffocate the animal, 

 mouth hot ; tongue coated with white fur. The tumor 

 under the jaw and about the centre of the channel soon 

 fills the whole space, and is evidently one uniform body, 

 and may thus be distinguished from glanders, or the en- 

 larged glands of catarrh. In a few days it becomes more 

 prominent and soft, and evidently contains a fluid. This 

 rapidly increases ; the tumor bursts, and a great quan- 

 tity of pus is discharged. As soon as the tumor has bro- 

 ken, the cough subsides, and the horse speedily mends, 

 although some degree of weakness may hang about him 

 for considerable time. 



Treatment. — As soon as the tumor under the jaw is 

 decidedly apparent, the part should be actively blistered. 

 It should be washed off as soon as it rises, and if repeated in 

 a day or two, this will abate the internal inflammation 

 and soreness of the throat aud promote the suppurative 

 process ; (when the glands remain hard and do not suppu- 

 rate, it may lead to glanders, in which case the use of 

 Iodine Ointment as an outward application and hydriodate 

 of potash in daily doses of ten to forty grains, combined 

 with tonics will be found useful as an internal application.) 



As soon as the swelling is soft on its summit, and evi- 

 dently contains matter, it should be freely and deeply 

 lanced, after which apply a linseed j)Oultice. If the in- 

 cision is deep and large enough, no second collection of
