This, however, did not require a great effort of the imagination,for we have only impressed the same modification of the embryotomy forcepsthat Smellie and Levret long since gave to the one invented by the curvature is intended to fulfill the indication of accommodating the shape ofthe instrument to that of the curved canal it has to traverse.
