DISEASES OF ‘THE RESPIRATORY ORGANS. 101 
Treatment.—The cause of the trouble must be ascertained before 
treatment is commenced. In the many cases in which the animal is 
in poor condition (in fact, in all cases) he should have the most nutri- 
tive feed and regular exercise. The feed, or box containing it, should 
be placed on the ground, as the dependent position of the head favors 
the discharge. 
The cases that do not require a surgical operation must, as a rule, 
have persistent medical treatment. Mineral tonics and local medica- 
tion are of the most value. For eight days give the following mix- 
ture: Reduced iron, 3 ounces; powdered nux vomica, 1 ounce. Mix 
and make into 16 powders; one powder should be mixed with the 
feed twice a day. Arsenious acid (white arsenic) in doses of from 
3 to 6 grains three times daily is a good tonic for such cases. Sulphur 
burnt in the stable while the animal is there to inhale its fumes is also 
a valuable adjunct. Care should be taken that the fumes of the 
burning sulphur are sufficiently diluted with air so as not to suffocate 
the horse. Chlorid of lime sprinkled around the stall is good. Also 
keep a quantity of it under-the hay in the manger so that the gases 
will be inhaled as the horse holds his head over the hay while 
eating. Keep the nostrils washed and the discharge cleaned away. 
from the manger and stall. The horse may be caused to inhale 
the vapor of compound tincture of benzoin by pouring 2 ounces of 
this drug into hot water and fumigating in the usual way. 
If the nasal gleet is the result of a diseased tooth, the latter must 
be removed. Trephining is the best possible way to remove it in 
such cases, as the operation immediately opens the cavity, which can 
be attended to direct. In all those cases of nasal gleet in which 
sinuses contain either tumors or collections of pus the only relief is 
by the trephine; and, no matter how thoroughly described, this 
is an operation that will be seldom attempted by the aonprotescionl: 
It would therefore be a waste of time to give the modus operandi. 
An abscess involving the turbinated bones is similar to the collec- 
tion of pus in the sinuses and must be relieved by trephining. 
THICKENING OF THE NASAL MEMBRANE. 
This is sometimes denoted by a chronic discharge, a snuffling in the 
breathing, and a contraction of the nostril. It is a result of common 
cold and réquires the same treatment as prescribed for nasal gleet, 
namely, the sulphate of iron, sulphate of copper, iodid of potassium, 
etc. The membranes of both sides may be affected, but one side only 
is the rule; the affected side may be easily detected by holding 
the hand tightly over one nostril at a time. When the healthy side is 
closed in this manner the breathing through the affected side will 
demonstrate a decreased caliber or an obstruction.
