or four fasting men, and stir it altogether against the bottom of the dish with a pot-stick, until the time that the quicksilver be quenched with the water, and then take ye as much verdigris as of the quicksilver and mingle it with spittle, always stirring with a pot-stick, as I have said before, until the time that they can be all mingled together. And after take old swine's grease without salt, a great piece, and take away the skin above, and put it in the dish that I spake of, with the things before said, and mingle and stamp it altogether a long while, then keep it to anoint the hound there where he hath the mange and in no other place, and certainly he shall be whole. This ointment is marvellous and good and true not only for this thing, but also against the canker and fistula and farcy and other quick evils, the which have been hard to heal in other beasts. That other is a common mange when the hounds claw themselves with their feet and snap with their teeth, and it is on all the body of the hound. And all manners of mange come to hounds from great travel and from long hunting, as when they be hot they drink of foul water and unclean, which corrupteth their bodys, and also when they hunt in evil places of pricklings of thorns, of briers, or peradventure it raineth upon them, and they be not well tended afterwards. Then cometh the scab, and also the scab cometh upon them when they abide in their kennel too long[120] and goeth not hunting. Or else their litter and couch is uncleanly kept, or else the straw is not removed and their water not freshened, and shortly the hounds unclean, I hold, and evil kept _or long waterless_, have commonly this mange. For the cure of which take ye the root of an herb that groweth upon houses and walls, the which is called in Latin iroos[121] (iris) and chop it small and boil it well in water, and then put thereto as much of oil made of nuts as of water, and when it is well boiled cast out the herb, and then take of black pitch and of rosin as much of the one as of the other, well stamped, and cast it in the water and the oil before said, and stir it well about on the fire with a pot-stick: and then let it well grow cold, and anoint the hound as before is said. Sometime cometh to the hounds sickness in their eyes, for there cometh a web upon them, and growing flesh which cometh into that one side of the eye, and is called a nail[122], and so they grow blind unless a man take care thereof. Some men put about their necks a collar of an elm tree both of leaves and of bark, and seeth that when that shall be dry the nail shall fall away, but that is but a little help. But the true help that may be thereto is this, take ye the juice of a herb that men call Selidoyn (Celandine)[123] powder of ginger and of pepper, and put all together thrice in the day within the eye, and let him not claw nor rub it a long while, and that customarily by nine days until the
