BOOK FOURTH. SECT. I.—ON ELEPHANTIASIS. Well, in my opinion, did Aretæus the Cappadocian say, that the power of remedies ought to be greater than those of diseases; and that for this reason elephantiasis is incurable, because it is impossible to find a medicine more powerful than it. For if cancer, which is, as it were, an elephantiasis in a particular part, is ranked among the incurable diseases by Hippocrates himself, how much more is not elephantiasis incurable, which is, as it were, a cancer of the whole body? But the black bile from which this affection is formed, having a double origin, (for it arises either from the melancholic and feculent part, and, as it were, dregs of the blood, or from yellow bile, both being overheated); the first variety of the black bile produces the reddish elephantiasis, which is the more mild, or to speak more truly, less malignant variety; the others which are more malignant, being accompanied with ulceration of the whole body and falling off of the extremities, are produced by the latter variety, or that from yellow bile overheated. Wherefore, those who are already overpowered by the disease, must be abandoned; but when the affection is in its commencement, so as that none of the extremities has fallen off, nor the surface of the body become ulcerated, nor the hard swellings appeared, and the face merely appears foul, but not altogether unseemly, we must attempt the cure. For not a few, by merely burning the head, have prevented many who were beginning to be affected from being overpowered by this disease. Wherefore, at the commencement of the disorder, we must have recourse to venesection repeatedly, more especially if in spring, when the complaint is most apt to occur, and has its exacerbations. After an interval of a few days, say nine or ten, we may purge them with the pottage of colocynth, not once only but frequently, proportioning the dose of the medicine to its strength. Purging with hiera also suits well with them. After the interval of about ten days again, we must give them the vinegar of divided milk, not in less quantity than three heminæ, nor in greater than five, and on the following days they are to be supported with milk that is not divided into parts, or new-drawn milk; by which means, if the affection yield,
