Molten-Grease, a disorder in horses, consisting of a fat or oily discharge with the faeces : it arises from a colliquation or melting down of the animal's fat, in consequence of violent exercise in very hot weather.

This disease is always attended with fever, heat, restlessness, starting and tremblings, great sickness-shortness of breath, and sometimes with inflammatory symptoms. The horse rapidly becomes lean, and, if it survive this attack, commonly grows hide-bound ; his legs swell, and continue in that state, till the humours are in a more natural condition; but, if the disorder be neglected, the farcy, or an obstinate surfeit, generally succeeds, and which is with difficulty removed.

The first step towards effecting a cure of this malady, ought to be profuse blood-letting 5 an operation which should be repeated, though in smaller quantities, for two or three successive days. Immediately after these evacuations, two or three rowels should be introduced, with a view to promote a large drain; while cooling emollient clysters are administered, to abate the fever. The drink should consist of warm water or guel, with cream of tartar, or nitre, in order to dilute or attenuate the blood ; which, in this case, is greatly disposed to become clotted, and to engender a total stagnation of the fluids.

When the fever has abated, and the horse has recovered his appetite, the following mild purgative should be given once a week, for some time, till the disorder be entirely removed : Take of Socot rine aloes 6 drams, of pulverized gum guaiacum 1/2 an ounce, of diaphoretic antimony and powder of myrrh, each 2 drams; form the whole into a ball with syrup of buckthorn. While this medicine is operating, the horse's labour should be suspended for two or three days every week : thus, he will lose neither his flesh nor appetite, but improve in both; because this ball is, on the whole, preferable to any other preparation for that purpose.
