    Reprinted from Vol. XV of the ' Ophthalmological Society's Transactions.''] Discoloration of the cornea with blood-pigment. By E. Treacher Collins. (With Plate IV, fig. 1.) In October, 1890, I brought before this Society two cases of a peculiar form of discoloration of the cornea with blood-pigment. Three cases of a similar description had been previously published by Vossius, and one by Lawford; since then two others have been recorded by Weeks of New York, and John Griffith. I have now the notes of nine more to add to these. A study of the seventeen cases has enabled me to write a fairly complete account of the affection, and as a description of it has not yet found its way into the text-books on eye disease, I think it will be interesting to members of this Society, to read to them the result of my extended inquiries into it this evening. The cases so far recorded have all been brought forward by those to some extent engaged in microscopical work, but it must not, therefore, be thought that the condition is only a pathological curiosity. It is one which frequently involves, as all those who have written on it have mentioned, a very nice point in diagnosis; the curious fact being that the difficulty consists in distin- guishing it from a condition of a widely different nature. Those who have not seen this form of discoloration of the cornea would hardly believe it possible that it could be confused with a lens dislocated into the anterior chamber, and yet I have seen some of the best observers doubtful in deciding between these two conditions. The discoloration in all but two of the cases involved the whole cornea, except a narrow ring varying in width
