The other day Dr. Greene, assisted by Dr. Taylor, operated on the eye of Mort Petro, of Darlington, which was put out 13 years ago. Petro by a recent accident had almost completely lost the sight of his other eye, so it was decided to operate on the eye first put out, its vision being lost by the destruction of the pupil. A new pupil was cut and when the bandages were removed this morning, Petro was enabled to see objects about the room and the pictures on the wall. He was greatly pleased with the success of the operation.
