    460 and the number of cases in which the irrigator was no used was 40—total, 500. N.B.—In a few cases the irrigator was not used either because the chamber was clear and the iris in good position or because a minimum of interference with the eye was indi- cated. The bulk of the 40, however, were performed before the irrigating apparatus was available. Visual results after operation.—Spheres only were used and the patients were tested with miniature bull’s eyes (M.B.E.) at distances from one to six metres. A vision of M.B.E. at six metres equals T°d vision by types or rather more. This result has been obtained by careful comparative experiments with educated patients. The cases were tested on discharge as it is impossible to test so many cases except by strict routine. A percentage were got hold of later and re-tested and none of these had degenerated in vision after the testing, while many had improved greatly. Visual Results.
