chapter 16

on "the cauterization of eyelid when its hair grows reversedly into the eye," he recommends treatment by cautery and by medicine. In cautery, the area where fire is to be placed is marked with ink in the shape of a myrtle leaf. In drug treatment, the caustic medicine is applied to the eyelid over a paper in the shape of a myrtle leaf (fig. 2).
