THE HORSE—THE RESPIRATORY ORGANS, 103 
COLD.—CAT 
CORYZA. 
By these terms is meant an inflammation of the mucous membrane of 
the nose, throat and air-passages, with fever. Though often of little 
moment, it frequently endangers life. It is caused by stoppage of perspira- 
tion from a draught of air, or from standing in the cold after vigorous ex- 
ercise. It may: be confined to the nose, when it is called nasal catarsh, or 
may extend throughout the respiratory system. 
Symptoms.—Apparent laziness and slowness; frequent cough and 
snorting; watery discharge from the nose and eyes, with inflammation; 
want of appetite; nusal membrane unusually red; membrane lining the 
eyelids and covering the eyes congested; pulse feeble and perhaps in- 
creased; sometimes swollen glands and sore threat, in which case the appe- 
tite declines, and swallowing even water is difficult, 
the horse holding the water in his mouth, or plung- 
ing his nose into it; the urine grows scanty, thick, 
turbid, strong and highly colored; the dung passes 
in small quantities and is covered with mucus; the 
nasal discharge becomes thick, white or yellow, or 
of a slate-color, when fever symptoms disappear, 
leaving no cause for alarm, excepting the liability 
to terminate in glanders, chronic cough, pneumonia, 
or the like, if neglected. Catarrh is often preceded 
by some constitutional trouble, and is distinguished 
from simple cold by local excess of blood in the 
mucous membrane lining the larnyx, pharynx and Symprom or CoLp oR 
ATARRREH. 
glands near those parts, by which the natural secre- 
tion is at first stopped and then returns, or is replaced by a mucous, watery 
discharge, or mucous matter with pus. 
TREATMENT.—In the first stages, attended with staring of the coat, 
shivering, lassitude, yawning, watery discharge from the nose and eyes, 
give a halfiounce of tincture of camphor in a mixture formed from the 
white of an egg and a teaspoonful of oil beaten together, and added toa 
gobletful of water; repeat the dose in half an hour if shivering continues. 
Aconite is needed when fever comes on with quick and full pulse after the 
cold symptoms; for respiration exceeding fourteen per minute; for a skin 
alternately hot and cold; dry, short, and frequent cough; mouth hot, 
and appetite bad; highly colored urine. It is not suitable for the late 
stages, or for fever of a weak or low type. Give nux vomica when there 
is fever of a low type, with gastric symptoms, constipation, and white or 
shining coat on the tongue. Administer mercurius for thick mucous dis-
