Others 4-again, for covering a loss ofsubstance, take the externalskin either in the form ofsmall flaps grafted upon thesurface, or as pedicellate flapswhich are thrust in betweenthe eyeball and the lid througha fenestra cut.

As 6 bone of orbit-D-lan adjunct in these different methods we may directly after the completion of theoperation insert a properly fitting shield into the new conjunctival sac between theeyeball and the lids and let it stay until firm cicatrization has ensued. Generally speaking, we are obliged to acknowledge that in extensive adhesionsall methods have but scanty results to offer, since the symblepharon commonly returnson account of the subsequent shrinking of the conjunctiva. 822. [Formation of New Cul-de-Sac.—When the symblepharon is such as toobliterate the fornix, a new fornix may be made (especially for the reception of anartificial eye) by inserting a Wolfe graft into the groove made by dissecting out thecicatricial tissue, anchoring the graft down by stitches passed through t
