The lower lid is raised a little and covers the extremelower part of the cornea, and the upper lid drops a good deal so that its border liesonly a little above the center of the cornea. Then the interpalpebral zone forms uponthe cornea a zone from 4 to 6 mm. in breadth which occupies the lower half of thecornea, with the exception of its extreme lower part, and with which there is con-nected on either side a very small triangle of scleral conjunctiva. The interpalpebralzone as thus defined is the part which more than any other is constantly exposed toexternal injuries. Hence, in many men we find this portion of the scleral conjunctivasomewhat injected all the time, and later on in life we find it occupied by the Pinguec-ula.
