![Dissection.—The shape of the eye was scarcely changed, though there was a large, firm, melanotic tumour adhering to the outer posterior half of the sclerotic, causing exophthalmos. No melanotic tumour was perceptible within the eye. Tension slightly diminished. Cornea transparent. Anterior chamber shallow. Pupil dilated, irregidar; a yellow, opaque reflec- tion emanated from its area. Crystalline lens large, dirty yellow, and opaque. Retina and vitreous missing. Sclerotic and choroid in apposition. The space behind the lens was occupied by a gelatinous, yellowish substance, resembling vitreous, and by a peculiar yel- lowish, chalky, soft substance. Microscopical sections prepared from this eye.—Slides 1 & 2. Sections of the retina from near timjjouator. The portion of the framework between the outer granidar layer and the optic nerve-fibres can be recognized ; it encloses few granules and numerous brown pigment- molecules. The rods, the optic nerve-fibres, and the retinal elements immediately beneath the optic nerve-fibres have disappeared. Slides 3 & 4. Sections from the melanotic growth: they show a dense network of short fibres and of small cells, ahnost completely hidden from view by large, irregularly shaped, deep-brown pigment-masses. Slide 5. A portion of choroid from the equator, showing the disturbed state of the choroidal epithelium, the almost transparent choroidal tissue being sprinkled with deep-brown pigment-molecules, with irregularly shaped pigment-cells. 17G. The lateral half of a melano-medullary growth, together with some of the soft parts of the orbit and portions of a thickened shrunken sclerotic. No other elements of the eye can be recognized. 177. The opposite half of the same specimen. E. W., aged 66 (under the care of Mr. Streatfeild, Eoyal London Ophthalmic Hospital), a healthy-looking women of fair complexion, lost the left eye many years ago; the right has recently been destroyed by a cancerous tumour, which at the time of removal protruded from the orbit. This was excised, June 6th, 1859. On dissection nothing of the eye could be distinguished, except the portion of sclerotic seen in the preparation. ] 78. The posterior and lateral portion of a left eye, the section being carried through the middle of the optic nerve and parallel with its fibres. The optic nerve is on one side separated from its sheath by a melanotic cancerous mass, which appears to have originated in the choroid, and also to have grown into the interior of the eye, displacing the retina. The retina is greyish white and opaque, and loosely attached to the choroid; it is, near the optic- nerve, surrounded by the melanotic growth, across which it can be traced](https://iiif.wellcomecollection.org/image/b21641857_0095.jp2/full/800%2C/0/default.jpg)
