The blood may be in fault in two ways, in quantity and in quality; in quantity, when it is so consumed that no surplus is left over, as in viragoes or virile women, who, through their heat and natural strength, consume it all in their last nourishment; as Hippocrates writes of Prethusa, for when her husband praised her overmuch, her courses were suppressed, her voice changed and she got a beard with a manly face.
