NASAL CATARRH. 



Synonyms. — Common cold; Coryza. 



Definition. — Nasal catarrh is an acute inflammation of the mucous

 jaws, and by a snorting cough, with or without perceptible fever. 



Etiology. — Nasal catarrh in adult horses usually arises from some 

 neglect in the management of the animal or of the stables — from sudden 

 changes of temperature, and from exposure to cold and wet. Young 

 horses which have been at pasture, when first kept in warm stables, are 

 frequently affected with it.
