CATAREH. 17 



to a horse suffered to stand in any situation where he is 

 exposed to a current of air. But, in most of these cases, heat 

 will be found to have supervened before the disease comes 

 to manifest itself. 



Four kinds of catarrh : — simple, when void of fever ; 

 febrile, when attended by fever; chronic, when of long and 

 tedious duration; epidemic or influenzal,^ when attacking 

 many at one time, and accompanied with remarkable pros- 

 tration of strength and loss of condition. 



The symptoms of simple catarrh (which some might call 

 Coryza'^) are, a watery distillation, accompained with, or else 

 quickly succeeded by, a defluxion of flakes of mucus from both 

 nostrils — rarely from one alone ; some slight humid blush of 

 the Schneiderian membrane; oozing of tears from the corners 

 of the eyes, with globules of mucus observable in them ; 

 small, loose, diffuse swellings under the jaw ; occasional 

 snorting, perhaps coughing as well, with or without slight 

 soreness of throat : but without depression of spirits or loss of 

 appetite. 



Febrile catarrh may be either slight or severe. When 

 slight, it is nothing more than the simple form, accompanied 

 with some unusual dulness and fastidiousness of appetite, and 

 some little fever, preceded perhaps by shivering : this being 

 the ordinary form in which catarrh presents itself. The 

 severe form is that in which the depression is greater, the 

 appetite nearly or quite lost, the fever comparatively high, — 

 the membranous reddening greater, with tvirgidity also of the 

 Schneiderian membrane. Its surface will either appear quite 

 dry, or there may be a scanty, yellowish, albuminous fluid, 

 turning afterwards into a thick muco-purulent running, and 

 becoming altogether as abundant as it was at first sparing.

2 Youatt (in his Lecture VI, in the * Veterinarian' for 1832) makes a distinc- 

 tion between coryza and catarrh ; by one being " inflammation of, and defluxion 

 from, the nasal membrane, or the cells with which it is connected;" the other 

 (catarrh) "the same thing extending to the fauces." Dr. Good has made 

 coryza and catarrh different diseases. Unless coryza be a simple nasal gleet, 

 these distinctions will prove puzzling to make in j^ractice.
