melancholy which affects them, the poison putting on the nature of that humour in like manner as we know other melancholic persons dreading some one thing and some another; which reason accords also with those who say that they think they see the image of the dog that bit them in the water. Of persons falling into this affection we know none who has been saved, except that we have learned the histories of one or two cases, and these were of persons who had been bitten, not by a mad dog, but by some person who had been bitten and imparted the disease to them. But before the affection has made its attack many, even of those who have been bitten by a dog, have been saved. Wherefore we must begin the treatment from thence. And since often from the attack of hydrophobia having not yet come on (for most commonly it comes on about the fortieth day, and in some cases after six months, nay, instances are related of its coming on after seven years,) some supposing that the dog who inflicted the bite was not mad, and making haste to heal up the wound have thereby given rise to the complaint. By the following experiment you may ascertain whether the bite was inflicted by a mad dog or not: Pound walnuts carefully and apply them to the wound, and next day take and present them for food to a cock or hen. At first indeed he will not touch them, but if he is compelled by hunger to eat of them, observe, for if the dog that inflicted the bite was not mad, then the fowl will live, but if mad he will die next day; and then you must hasten to open the wound, and after a few days repeat the same experiment; and when the fowl does not die you may bring the wound to cicatrization, inasmuch as the patient is then freed from danger. Oribasius recommends this experiment: If from the symptoms which we have mentioned we know for certain that the dog is mad, we must have recourse to medicines for laying open the sore, the principal of which is that from pitch, very acrid vinegar, and opoponax, which is described accurately in the section on the wounds of nervous parts. But if the person who has been bitten has a tender skin, it is to be diluted with oil of iris, of balsam, or the like; or having first fomented the sores, apply a cataplasm of garlic. This also forms eschars. A dry escharotic for persons bitten by mad dogs: Of fossile salts, dr. viij; of chalcitis, dr. xvj; of squills, dr. xvj; of green rue, dr. iv; of scraped verdigris, dr. iv; of the seed of horehound, dr. j; use it at first dry that it may form an eschar, and then with rose-oil that the eschars may fall off. Keep the parts from cicatrizing for forty-two days at least. A cataplasm for persons bitten by mad dogs, which keeps the mouth of the wound open: Apply a cataplasm of onions with salts and rue, or of laserwort with salts, or of old pickle, or of the cinders of burnt wood with oil, or of garlic, or apply the leaves of the elder tree, or mint, or baum, each with salts, or walnuts with onions, salts
