The haw, or third eyelid, as it is sometimes called, is a fold of membrane situated at the inner corner of the eye, capable of expansion, and is used to sweep across the globe of the eye to cleanse it from flies, dirt or other foreign bodies that have blown in. This membrane, from constitutional causes, from blows or irritation from extraneous matter lodged in the eye, becomes inflamed and enlarged, which interferes with the sight, preventing the eyelids from closing. My Eye Lotion No. 2 would do good here also, the treatment being astringent lotions, lunar caustic, or cutting off the excrescent growth, according to the circumstances of the case.
