110 DISEASES OF THE HOESE. 



tive food and regular exercise. The food, 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 sixteen powders. Give one powder mixed with the 

 food 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. Chloride of lime sprinkled around the stall is good. Also 

 keep a quantity of the chloride 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 keep the discharge 

 cleaned away from the manger and stall. The horse may be caused 

 to inhale creolin vapor or the vapor of compound tincture of benzoin 

 by pouring 2 ounces of these drugs into hot water and fumigating in 

 the usual way. 



If the nasal gleet is the result of a diseased tooth, the tooth must 

 be removed. The operation of trephining is the best possible way to 

 remove the tooth in such cases, as it immediately opens the cavity 

 which can be attended to direct. In all those cases of nasal gleet 

 where sinuses contain either collections of pus or tumors, the only 

 relief is by the trephine ; and, no matter how thoroughly described, 

 this is an operation that will be very seldom attempted by the non- 

 professional. It would therefore be a waste of time to give the modys 

 operandi. 



An abscess involving the turbinated bones is similar to the collection 

 of pus in the sinuses, and must be relieved by trephining. 



THICKENING OF THE 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 requires the same treatment as prescribed for nasal gleet, 

 namely, the sulphate of iron, sulphate of copper, iodide of potassium, 

 etc. The membranes of both sides may be affected, but one side only 

 is the rule; and 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.
