Elimination of toxins and waste products is to be secured and this is more safely conducted by the kidneys or skin than by the irritable alimentary canal. Plenty of pure cold water is one of the best and simplest resorts. Aside from this, where there is much hyperthermia, bicarbonate of potash or soda will serve the various purposes of an antidote to the acid blood, an eliminant and an antithermic. Under the same circumstances saltpeter may be resorted to in ½ oz. doses twice daily. When, however, the heart is weak it is better to employ ammoniacal or etherial diuretics:—spirits of nitrous ether, 1 oz. or liquor of acetate of ammonia, 2 to 4 ozs. By combining these with extract of belladonna and camphor a fairly standard prescription may be prepared. Inhalations of warm water vapor, rising from hot water or a hot mash in a bucket, over one end of which a bottomless bag is drawn, while the other end receives the nose of the horse, will greatly relieve the irritation and the cough. It can be made even more soothing by introducing a little alcohol, eucalyptol, menthol, camphor, poppy-heads, or other anodyne. Or the water vapor may be set free in a close stall from a boiling tea-kettle or a steam pipe, and an admixture of sulphurous acid made by burning a few pinches of sulphur, more or less according to the size and closeness of the stall. If the stall is tight enough a steam bath may be given with much profit in the early stages. Counter irritants applied to the throat, or, if need be, to the breast and sides of the chest will often give material relief, acting as derivatives and probably also by modifying the globulins in the exudate and thus influencing the course of the disease. In case of sore throat of a very high type it may be best to apply a compress or poultice, or even a piece of sheepskin for a day or two, until, by antithermics, cooling diuretics and soothing inhalations, the severity of the inflammation has abated. The common mustard pulp made with tepid water, rubbed in, and covered by paper, may be applied for an hour; or the _soap liniment_ (soap 6 ozs., camphor 3 ozs., and proof spirit, liquor ammonia and linseed oil aa 1 pint) may be rubbed on repeatedly; or a blister of cantharides may be used. The _ophthalmia_ may be treated by a moist atmosphere, a few drops twice daily of a solution of atropine beneath the lids, a similar treatment with pyoktanin, (1:1000), or a solution of mercuric chloride (1:2000).
