    nerve-fibres and the blood-vessels can be recognized along the walls of the excavation. The granules of the retina may be distinguished near the retinal aperture. 51. The outer lateral half of a somewhat shrunken right eye, the section being car- ried rather obliquely through the optic nerve. The brown choroid and the sclerotic are in apposition in some, and detached from each other in other places. The sclerotic is much thickened round a cicatrix in the ciliarj' region. The lens is absent. The iris, ciliary processes, and hyaloid fossa are drawn together by inflammatory products, by which also the small anterior chamber is occupied. The greyish, strongly translucent retina has in some places become detached from the choroid. The choroidal surface of some of the detached portions of retina is sprinkled with pigment-molecules. 52. The other half of the same eye, preserved in pyroxylic spirit and water. The retina and the inflammatory efl'usions have become yellowish white and opaque. J. H., aged 11 (under the care of Mi*. Critchett, Royal London Ophthalmic Hospital), a healthy, red-haired boy, had, on November 22, 1860, the right eye cut by a piece of glass, which flew off a bursting glass bottle; the piece fell out. Vision was lost instan- taneously ; the eye was never painful. The left eye seemed weak for a few days. Seven weeks ago it was scratched by a finger-nail; this was followed by protracted inflammation and photophobia, without pain. The right eye was excised, August 9th, 1861, Dissection.—Tension moderate. The eye was smaller than natural, and irregularly shrunken; its tunics drawn inwards by a cicatrix, which ran across part ofthe cornea and the adjoining ciliary region. Cornea translucent, the iris in apposition with it; the pupil implicated in the cicatrix. Lens missing. Vitreous space occupied by transparent yellow fluid. 53. Anterior lateral and posterior lateral portions of the tunics of a left eye. In the former a part of the greenish, opalescent, almost transparent lens may be seen; in the latter the section is carried through the middle of the optic nerve, and parallel with its nerve-fibres. The sclerotic and the deep-brown choroid are in apposition with each other; the apices of the cOiary pro- cesses touch the margin of the lens. The retina is greyish, translucent, and thrown into delicate folds ; round the optic nei*ve it is almost opaque and is much thickened. £
