improved its vision and diminished pain, but only temporarily, so that it had to be repeated at short intervals. The condition was so far stationary toward the end of October that the right eye continually gained visual power, but the left stood still and fluctuated from worse to better, with the greater or less severity of the neuralgic paroxysms. Pupils always in extreme dilatation. In the end of October and beginning of November (the patient had worn a large seton for a month) remarkable changes occurred; the neuralgia of the left globe diminished steadily, the pupil got smaller, the visual power increased, the neuralgia now was only on the lower lid, which was slightly red and painful to the touch, and had continual spontaneous pain. Visual power of right eye No. 3, of left eye No. 5. Visual field intact; with full illumination by weak light there is a peripheral torpor, but only in a narrow zone. The hyperæmia now extended more and more over the lower lid and the upper part of the cheek; this was apparent during the paroxysms, which were very severe, and destroyed sleep; it did not allow the skin to be touched; the color was deep (with high temperature) and extended to the angle of the mouth. This phenomenon lasted till the beginning of December, when neuralgia again attacked the left globe, with strong mydriasis and diminution of visual power (15 to 20 Jager), till at last the movements of the hand could hardly be distinguished, and this state of things continued with fluctuations up to the end of the month. The seton had been taken off just before the new outbreak; it was put in again on December 31st. In January the pains continued severe in the eye, with only one remission (from the 17th to the 20th), when the hyperæmia recurred in the cheek. On the 26th the pupil was very dilated, and fingers could not be seen at half a foot's distance. Visual field very limited, globe hard. A large upper iridectomy was made. After this the pupil was contracted, the pains diminished, visual power 10 Jager, field seven inches. In the middle of February the hysterical attacks recurred with great force; the patient was unconscious half the day; she was clear enough in senses when awake, but complained of buzzing in her head, as if a cock-chafer were inside it. From this till the middle of March, the left eye did not alter, the impairment of vision remained, with normal pupil and no pain in the globe, and the iridectomy seemed at least to have done good in one direction; but on the 13th of March the operated eye was again attacked with pain, visual power fell to No. 17, pupil became dilated, and after a few days the swelling, heat, and tenderness of the cheek recurred. During the years 1862 and 1863 the condition remained pretty much the same; _i. e._, the right eye sound, the left painful (in spite of the iridectomy) with dilated pupil, concentrically narrowed visual field, visual power fluctuating between No.
