glanders, purpura hseraorrhagica, etc. ; or it may occur as 

 the result of an injury, as a blow, kick, etc., causing 

 rupture of a bloodvessel in the nose. Nasal bloodvessels 

 are also ruptured sometimes in consequence of severe 

 exertion ; and bleeding occurs now and then without any 

 apparent cause. 



Symptoms. — A flow of blood, generally from one nostril 

 only, but occasionally from both nostrils. 



Treatment. — Astringent solutions may be forced into the 

 nasal chambers. The various preparations of iron are 

 useful ; solutions of lead acetate, alum, etc., are also useful. 

 In some persistent cases, plugging one nostril may have to 

 be resorted to ; cold water or ice may also be applied 

 externally. A string should be attached to the plug, for 

 the purpose of removing it when necessary. 



HiEMOPTYSIS: HEMORRHAGE FROM THE 

 LUNGS. 



Haemorrhage of the lung usually occurs in connection 

 with, and as a symptom of, some diseased condition of the 

 lung structure, as pulmonary congestion, etc. The primary 

 cause in a great many cases is the performance of some 

 severe exertion by the animal when not in suitable con- 

 dition ; most commonly met with in horses accustomed to 

 fast work, as trotting and running horses ; and a plethoric 

 animal, on being put to a little extra exertion, will some- 

 times suffer from pulmonary haemorrhage. 



Symptoms. — The blood issues from both nostrils; cough- 

 ing is present, showing laryngeal or tracheal irritation; 

 respiration becomes quickened, and on auscultation over 

 the region of the trachea, a peculiar rattling or gurgling 

 sound is heard. This sound is caused by the air rushing 

 through the obstructing blood and mucus; if the hsemor-
