The flap thus formed ia two structures is then carefully raised from the attachment to the external surface of the bone, and held aside by an assistant, with either a blunt tenaculum or forceps. The instrument is then implanted upon the centre of the exposed bony surface, and by the rotatory or semi-rotatory motion imparted to it, gradually separates a circular disk of the bone. The pressure necessary to make the instrument seize or bite on the bone may at first be considerable, but as the trephine penetrates, the force must be carefuUy relaxed in order to avoid the hazard of injuring the parts beneath by the sudden yielding of the bone and plunging of the iustrimient into the parts beneath, accompanied by the bony disk, as it separates from its last attach- ments, perhaps passing beyond reach, and costing no little touble and danger before it can be discovered and removed.
