In all the cases I succeeded in getting the anterior chamber clear, so that I could dilacerate the capsule, while keeping constantly the point of the cystitome in view. Prolapse of vitreous occurred nine times under the fol- ioicing circumstances:— Twice it was only one drop coming out during the trials of getting the remainders clearly out. Both eyes healed without irritation, with S = -J- and respectively. Twice it occurred in eyes with shrunken cataracts. The first was calcareous and disciform in an old woman. Such cataracts are difficult to get out. In this case vitreous escaped during the pressure of the spoon on the cornea. I succeeded, nevertheless, in pushing the cataract out without being obliged to enter the eye with an instrument. Healing perfect; S=TV in an eye unhealthy apart from the cataract. The second case was a soft cataract, with many earthy and fatty deposits on the capsule. After the exit of the lens I tried to extract the anterior capsule, but in this attempt I ruptured the hyaloid fossa, and some vitreous escaped. This had the advantage to push the capsular opacities aside, and form a clear pupil. The patient had no trouble, and was very soon discharged with S = J. The fifth case was that of an excessively myopic eye, in which I presup- posed the vitreous to be fluid and other changes present. I therefore extracted the lens with its capsule by means of a large spoon. The operation was done easily, and com- plicated with prolapsus vitrei only to a limited extent. The eye healed without trouble, but regained no higher
