Macerate for twenty-four hours, and then add rectified spirit of wine, four ounces; solution of corrosive sublimate in muriatic acid, one drachm. To be kept well corked for two or three weeks before it is used: it may then be either strained through blotting paper, and used as a transparent tincture, or merely shaken up and employed as it is. The solution of sublimate should be added at the time the blister is used. Rectified spirit 2 oz. Liquid ammonia 2 oz. Oil of turpentine, origanum, or rosemary (either) 1 oz. Powdered cantharides 6 dr. to 1 oz. Mix. After a blister has been applied to the legs or hocks, the litter should be removed, and the horse’s head should be confined or tied to the rack, to prevent his rubbing the part with his nose; but this may be done better by putting what is termed a cradle or necklace round his neck; he may then be turned loose into a box and exercise himself, which is very desirable after blistering. It is necessary to keep the cradle on for about a fortnight, as they are apt to gnaw the part or injure the skin, when the effect of the blister is going off, and an itching only remains. The following is a convenient method of making a blister, when the other ingredients cannot be obtained:—Take of the blistering plaster, sold by druggists, two ounces, melt or rather soften it by a gentle heat, and mix with it oil of turpentine from half an ounce to one ounce. * * * * * _Blistered Heel._—If your heel should become galled by walking in a water, or any other boot, you will immediately remedy the inconvenience by applying a piece of gold-beater’s skin, and over that a little court plaster, in order doubly to defend the part. But even in this trifle there is a right and wrong way of going to work. Instead of cutting with scissors, and merely wetting the plaster, let it be for a moment heated by the fire, as well as wetted, being previously stamped with a wadding punch; by which means, from having no angles, or corners, it will stick as fast as your own skin; provided that, when on and dry, you put over it a little cold cream, or any kind of grease, in order to repel the damp. The application that has been usually recommended to me by surgeons is a diachylon plaster, which, in cold weather, curls up and torments you so much in walking, that you soon become lame again, and then wish the doctor at Jericho. Go to Godfrey’s or some other first-rate chemist, in order to get the sticking plaster in perfection, as many a one has poisoned his skin by not having the genuine article. * * * * *
