in surgery, commonly called the flye, is a sort of tubercle that grows on the eye-lids. When small, it is seated on the edge of the eye-lid; but when large, it spreads further. When they do not suppurate, they become wens. They are apt to disappear and return. If there is inflammation, endeavour to suppurate it with the white-bread poultice: if it is hard, destroy it with a mixture of equal parts of hog's lard and quicksilver. If the lower eye-lid is affected, the tumor is more frequently on its inside; and then it is best to dissect it, or to make way for it outwardly by applying a caustic on the skin just upon it.
