Note: Jonson has defined wall-eye to be ``a disease in the
crystalline humor of the eye; glaucoma.'' But glaucoma
is not a disease of the crystalline humor, nor is
wall-eye a disease at all, but merely a natural
blemish. --Tully. In the north of England, as Brockett
states, persons are said to be wall-eyed when the white
of the eye is very large and distorted, or on one side.
