    eye from a stone about Christmas-time. On examination, his left eye appeared healthy, V. = 6/6. His right was slightly shrunken, the iris was discoloured, the pupil inactive to light except consensuously. There was a white reflex from the fundus, and the tension was slightly minus. On the supposition that it contained a new growth, the eye was excised the following day. He was subsequently seen on February 24, 1892. He then stated that after leaving the Hospital he was laid up in bed for a fortnight with headache and lightheadedness ; that he has never been strong since, and frequently suffers from dull head- aches. He has never had any discharge from the ears. There were no signs of past neuritis in the left eye. Pathological Examination.—The anterior chamber is shallow in the centre, and deeper in the perij>hery, due to pushing for- wai'ds of the lens and retraction of the root of the iris. The iris is adherent to the lens capsule at the upper part. There is umbrella-shaped detachment of retina. The vitreous is shrunken, and has what appears to be inflammatory effusion into it immediately behind the lens. On the outer surface of the detached retina, chiefly in the upper half, are several small, granular-looking, rounded projections, and close to the optic disc are some similar-looking growths. There is a large quantity of firm subretinal effusion. The choroid appears normal. Microscopical Appearances.—The posterior of the two uveal pigment layers on the back of the iris is at the pupillary border separated from the anterior, and adherent to the lens capsule. There is some increase in the number of round cells in the tissue of the iris in this region. There is more marked increase in the ciliary body between the muscle and the uveal pigment. The choroid is thin; there is increase of cells in it at the margin of the optic disc, but not much elsewhere. The lens shows some changes in the neighbourhood of its nucleated zone on one side; instead of flattened nucleated fibres there are large globular nucleated cells, and the cells lining the capsule extend round farther than usual. Adherent to the root of the iris on one side, and filling the circumlental space, is a dense mass of fibrous tissue, with scattered nuclei, patches of brown pigment, and blood vessels in it; similar tissue exists between the posterior surface of the lens and the detached retina, ad-
