Remove the cause by avoiding exposure and filth, and give a dose of the following: Powdered sulphur, } " sassafras, } equal parts. " cinnamon, } Dose, half a tea-spoonful, to be given in warm gruel. If this does not give immediate relief, dip an old cloth in hot water, (of a proper temperature,) and fold it round the animal's body. This may be repeated, if necessary, until the muscular system is relaxed. The animal should be wiped dry, and placed in a warm situation, with a good bed of straw. MEASLES. This disease is very common, yet is often overlooked. _Symptoms._--It may be known by eruptions on the belly, ears, tongue, or eyelids. Before the eruption appears, the animal is drowsy, the eyes are dull, and there is sometimes loss of appetite, with vomiting. On the other hand, if the disease shall have receded towards the internal organs, its presence can only be determined by the general disturbance of the digestive organs, and the appearance of a few eruptions beneath the tongue. _Treatment._--Remove the animal from its companions to a warm place, and keep it on thin gruel. Give a tea-spoonful of sulphur daily, together with a drink of bittersweet tea. The object is to invite action to the surface, and maintain it there. If the eruption does not reappear on the surface, rub it with the following liniment:-- Take one ounce of oil of cedar; dissolve in a wine-glass of alcohol; then add half a pint of new rum and a tea-spoonful of sulphur. Almost all the diseases of the skin may be treated in the same manner. OPHTHALMIA. _Causes._--Sudden changes in temperature, unclean sties, want of pure air, and imperfect light. _Treatment._--Keep the animal on thin gruel, and allow two tea-spoonfuls of cream of tartar per day.

Some animals are covered with vermin, which even pierce the skin, and sometimes come out by the mouth, nose, and eyes. _Symptoms._--The animal is continually rubbing and scratching itself, or burrowing in the dirt and mire. _Treatment._--First wash the body with a strong lie of wood ashes or weak saleratus water, then with an infusion of lobelia. Mix a tea-spoonful of sulphur, and the same quantity of powdered charcoal, in the food daily. RED ERUPTION. This disease is somewhat analogous to scarlet fever. It makes its appearance in the form of red pustules on the back and belly, which gradually extend to the whole body. The external remedy is:-- Powdered bloodroot, half an ounce. Boiling vinegar, 1 pint. When cool, it should be rubbed on the external surface.
