    Microscopical examination. Margins of eyelids and C07i- junctiva.Sections through the upper eyelid show the tarsus to have become doubled inwards on itself about its centre (PI. VI, fig- 2). The tarsus in the lower lid is not bent to the same extent, but the conjunctiva of the retro- tarsal fold commences to turn forwards directly where it ceases to be adherent to the tarsus. Immediately beneath the epithelium of the skin of the upper lid there is much small round-cell inflammatory in- filtration. Similar round-cell infiltration beneath the skin of the lower lid is confined to its free margin. The conjunctiva of the upper retrotarsal fold, which is entirely everted, is covered with numerous papillae having deep recesses between them. Immediately beneath the epithelium, especially in the vicinity of Krause's glands, there is much small round-cell infiltration, the ducts and loculi of the glands appearing imbedded in it. The surface epithehum is several layers thick, the most superficial cells being flattened, but none scaly or devoid of nuclei; a few goblet-cells are here and there seen. On passing away from the vicinity of Krause's glands the papillated condition of the surface of the conjunctiva continues, there is much new formation of lymphoid tissue beneath the epithelium, and much dilatation of lymphatic spaces. Co^^ea.—Sections which pass through the circular de- pressed area, previously referred to as possibly represent- ing the cornea, show that the epithelium which forms numerous papilla and downgrowths up to its margin, there ceases as a continuous layer. There is laminated fibrous tissue much infiltrated by leucocytes, very densely so at the anterior part, where clumps of epithehal cells im- bedded in masses of round cells are to be seen. On the free surface of this infiltrated tissue is a layer of what appears to be some coagulated homogeneous sub- Outer wall of (ryst.—The piece of sclerotic at the lower and posterior part of the specimen presents the usual
