CATARRH, 
Or what is commonly known as “ a cold,” consists of a febrile 
or inflammatory condition of the mucous membranes. When 
confined to the eyes and nostrils it its termed Coryza, from 
Kapa, the head, and few, to boil; signifying a fevered con- 
dition, or cold in the head. If it extends to the mucous 
membrane of the bronchial tubes, it gives rise to what is 
termed bronchitis. If to the alimentary tract, we have an 
enteritic or gastro-enteritic catarrh. The two latter are not 
unfrequent in distemper. 
The usual causes of common or simple catarrh are damp, 
cold, or contagion. 
Symptoms.—Increased secretion of mucus from the mem- 
branes affected, eyes watery, nose hot and dry, shiverings, 
sneezing, and sometimes cough, languor, fever, and con- 
sequent thirst. 
As the disease proceeds, these symptoms increase in 
severity, the mucous secretion becomes thicker, respiration 
impeded, the shiverings more frequent, languor greater,
