I gave a stroke of the scissors to the tumor, and the crystalline came out with the greatest ease, to all appearance whole, but extremely small. The iris did not re-enter spontaneously, but it was easy to restore it to its place. The pupil then appearing very small, I gave it a second stroke with the scis- sors, when the pupil which was of an irregular forni, appeared of sufficient size and of a perfect black. When I examined the eye on the fifth day after the operation, I found the pupil partly obstructed by the opake capsula, and partly contracted, but still sufficiently visible in the exterior and lower part of the iris, with a small round opening of a perfect black ; it appears more than probable that If the retina had not been previously enfeebled by a violent disorder resulting from the first operation the Marquis would have recovered the sight of his eye to a certain degree, without any difficulty.
