    points are well shown—namely, the malar bone, the outer edge of the orbit, the shadow which represents the position of the eye within the orbit, and the linear foreign body in its upper portion. The radiograph indicated that the position of my first magnet-opera- tion in the upper ciliary region was correct, and that had I proceeded further, or had the magnet been more powerful, I probably would have Fig. 1. A C A-B, outer margin of orbit C, foreign body. Tlie plate was placed against the left temple the light was directed into the eye obliquely from the nasal side. In the negative the lens can be dimly seen below C, but this does not show well in the reproduction or in the print. Exposure four minutes. secured the body ; therefore a triangular flap of conjunctiva was raised and a curved incision, 8 mm. in length, was made through the sclera in the upper ciliary region, about midway betAveen the insertion of the superior rectus and the corneal margin. The flat point of a large electro-magnet, kindly loaned for the purpose by Dr. Sweet, as it was more powerful than my own instrument, was introduced and almost im-
