A surgeon who maintains the use of the fixation forceps through the opera- tion, dragging the eye-ball hither and thither by an instrument the application of which is exquisitely painful, and a surgeon who obtains what seems to him a clear pupil at the close of the operation, but closes the eye without testing vision, and going again to work, if the test be unsatisfactory, until clearer sight is obtained, foils to appreciate the ad- vantages of non-ana\sthesia, and is not entitled to point a moral by the results he secures. As my colleagues at the Infirmary have not, as yet, in all instances acted on this understanding, I cannot ad- mit that their figures, good as they are, may not ultimatel}' be improved. The operations here reported were all performed according to the method of von Graefe, the single departure therefrom being in the cut itself, which was more corneal and less linear than that origi- nally recommended by him.
