Further this remedy, where it is necessary, generally were best to be divided into two days; for it is better at the first to lighten the patient, and after that to cleanse him thoroughly, than to run any risk of his life by dissipating all his strength at once. And if this method be found to answer in the cure of a dropsy, how much more must it of necessity answer with regard to the blood?

If the disorder be in the whole body, the evacuation ought to be made from the arm: if in any particular place, from the part affected, or at least as near to it as may be; because it cannot be performed every where, but only in the temples, and in the arms, and near the ancles. I am not ignorant, that it is the opinion of some, that blood should be let at the greatest distance from the part where it does harm; for that thus the course of the matter is diverted; but in the other way it is drawn into that very place, which is distressed. But this is altogether false. For it first empties the part nearest: and the blood flows from the more remote, as long as the evacuation is continued: when this is stopt, because there is no more attraction, it then ceases to come. Yet experience itself seems to have shewn, that in a fracture of the skull blood is to be let rather from the arm: and if the disorder is in one arm, it must be performed in the other: I suppose for this reason, because if any miscarriage should happen, those parts, which are already hurt(18), are more exposed to injuries. Sometimes also an hæmorrhage breaking out in one part, is stopt by bleeding in another. For it ceases to flow, where we would not have it, when we apply what will stop its course there, and open another passage for it.
