Theposterior surface of the lid is covered by conjunctiva which is intimately adherent to the subjacenttarsus, /., and over the latter presents isolated papilla; especially in the space between k and w, cor-reeponding to the upper (convex) border of the tarsus, still higher up in the vicinity of the fornix, /. the conjunctiva shows an adenoid character. The Meibomian glands have their orifices in front ofthe posterior edge OX the lid, h; above them Lie the branched tubular glands, w, w, and still higher upErausel glands, fcr, and in front of the latter Midlers musculus tarsalis superior, /, and the levator palpebral luperioris, / Prom the latter leashes of fibers pass between the muscular bundles of the orbic-ularis to the skill of the Lid. f, lax connective tissue; as, the arcus tarseus superior.

Butthe conjunctiva is present in such quantity at the fornix that the eyeis able to move in complete independence of the lids, the folds inthe region of transition being smoothed out or crumpled together, asthe case may be. Appearing through the lower fold of transition arethe extensive subjacent plexus of veins and also the white glisteningfascia. Its lax character and also its abundant blood supply render thefold of transition particularly liable to great swelling in inflammations ofthe conjunctiva. 121.
