    On separation of the lids an exceedingly small eyeball was seen ; what appeared to be the cornea, from the position of the insertion of the conjunctiva, was a very small opaque patch. There was a mass of firm tissue felt adherent to the lower and outer part of the rudi- mentary globe. The child's right eye was normal. He had a large hairy mole on the left temple, and an oval pigmented patch of skin over the left parietal bone. On March 15th, 1897, I removed the small eyeball with the mass attached to it, because it was absolutely useless, and would have prevented his wearing a glass eye. I afterwards pared the edges of the lids at the outer canthus, and united them over the exposed con- junctiva. Pathological examination: microscopical and macro- scopical appearances.—The small spot on the surface of the globe, around which the fringe of conjunctiva was attached, and which appeared to be the rudimentary opaque cornea, measured 4 mm. by 1 mm. Above and behind it, in the wall of the globe, a hard flat plate of tissue was felt, behind which again the optic nerve was seen where it had been cut across. Attached to the lower part of the globe in front of the optic nerve was a lobulated thin-walled cyst, the front wall of which had been cut into, and from which, on pressure, a clear straw- coloured fluid was made to exude. After the specimen had been hardened in formol it was opened by an antero-posterior section, and subsequently microscopic sections were cut. The area on the surface of the globe, around which the conjunctiva was attached, and where the anterior epithe- lium of the cornea is situated, does not extend over nearly the whole of the substantia propria, but only one side of it. This surface epithelium is prolonged into the subjacent fibrous tissue in the form of finger-like pro- cesses, so that it presents a very irregular base line; beneath it there is no sign of any anterior elastic lamina.
