BRONCHITIS. 255 



In other «ases the rale in the windpipe increases ; the 

 respiratory murmur gradually ceases throughout the lungs ; 

 the cough from being loose and moist, either dis^appears, or 

 becomes feeble and constrained ; and the pulse beats quicker, 

 and becomes thready in character. The disease in fact has 

 extended to the substance of the lungs, and the chances are, 

 that a patient thus affected, will die. 



Pathog:s"omo]S'io Symptoms. — The pathognomonic symp- 

 toms of Bronchitis are, the presence of mucous rales tvithin the 

 windpipe and the Ironchial tubes, accompanied with a loud 

 moist cough. 



Terminations. — Bronchitis may terminate in resolution, 

 or a gradual return of the animal to perfect health ; or in Pneu- 

 monia ; or in Chronic Bronchitis ; or in Thick Wind ; or in 

 Chronic Cough ; or in Typhoid Pneumonia. The latter of 

 which is very likely to supervene should Bronchitis prevail as 

 as an epizootic. As above stated, it may prevail as an epi- 

 zootic ; but, if it exists in a sporadic form, the causes generally 

 are as follows : — 



Causes. — Exposing horses to cold draughts, or to cold and 

 wet at the same time ; placing them in cold damp stables, 

 when the system is exhausted ; washing the body and limbs 

 with cold water, when the animal is exhausted, and leaving 

 them to dry without rubbing or bandaging. In short, any 

 cause which may give rise to Catarrh, may also produce Bron- 

 chitis. 



Treatment. — The best remedies in general are : Aconite 1, 

 Bryonia 1, Phosphorus 1, Aromatic Ammonia, Blisters, Pomen- 

 tations, and Injections.
