    extremely shrunken, and the pupil widely dilated. A large portion of the anterior surface of the iris was adherent to the periphery of the cornea. There was marked ectropion of the uveal pigment, most of the anterior surface which is left free being covered by the displaced pigment epithe- lium. The anterior chamber contained some blood-clot and discoloured opaque fluid. The central portion of the cornea, on section, could be seen to have a faint brownish colour. The vitreous was shrunken, and the retina de- tached from the ora serrata up to the optic disc. Microscopical appearances.—Scattered in small patches throughout the central portion of the cornea are numerous little highly refracting, fawn-coloured, granules. They are most abundant amongst the anterior layers, and some of them are situated between the laminae. In sections treated with ammonium sulphide the gran- ules are not stained, but a substance situated between the laminas takes on a dark greenish colour. In the logwood eosin stained specimens this substance is stained pink with the eosin. No blood-vessels or blood-corpuscles are seen in the cornea. The root of the iris is much atrophied, and intimately adherent to the periphery of the cornea. Case 3.—Jane T—, set. 14, was admitted to the Moor- fields Hospital, under the care of Mr. Tweedy, on July 12th, 1892. The evening before she had been struck on her left eye by a hammer. There was a small wound in the upper part of the cornea, with a prolapse of the iris and an hypopyon. The prolapsing iris was cut off, after which the anterior chamber filled with blood. On the 26th it was noted that the eye was still much injected, and that the blood was not being absorbed. The eye-ball was then excised. Pathological examination.—The tension of the eye imme- diately after removal was normal. There was a small partly healed wound in the upper half of the cornea. The anterior chamber was full of blood-clot. * The central portion of the cornea was of a rusty-brown colour on section ; the
