    extensive, and although she was myopic of the eye she could stiU read with, yet she could not see well at any distance, or with any glasses. You should remark that the bulging of the staphylomata in this case must have been very slight, if, indeed, there was any localised bulging, for the outlines of the optic nerve entrances are particu- larly convex externally, at that part of then- chcumferences next to the staphylomata, the hght spaces in the fundus of either eye, as if the optic nerve was drawn sideways more than backwards. There was no mistake in this case about her being myopic, the globes lengthened antero- posteriorly: the inverted image, by the direct method of examination with the ophthalmoscope, is a sm’e test of this. Comparing the two eyes, I think it was impossible, by ophthalmoscopic examination, to have told that vision of one eye was so much worse than of the other, or, mdeed, that in both it was so very imperfect. The left optic nerve entrance was somewhat palei’, and seemed flatter than the right. The choroid of either eye was, as I have said, imequally pale, more ui some parts tlian in others, but the choroid of the left eye was, of the two, altogether the palest, and the pigment islands least dis- tinctly marked, but this was all. The tension of either eye was nonnal, and alike in the two. I suppose that probably the white space or staphyloma of the left eye was of old standing, and that probably this eye, with which she could see so httle, had been long disused, for the choroid, although thin, was rather equally thinned, and not so much at any part near the atrophied choroid, as if any extension was progressing just at the time when my di-awing was made, nor was there any apparently definite limit peripherally to this thmner choroid. But of the right eye, if I may continue to speculate on the probabili- ties of the case, for I have no Imowledge of the patient before her recent short attendance here, I should say that the outer darker segment of the light space in this eye shows the recent extension of the disease in her useful eye, for
