    —though only in cxcc])lionnl cases—by Dr. Buck, of New York, in 1847; Kinlock, of Charleston, 1859; Hamilton, of New York, 185S; and Mr. Wheelhouse, of Leeds, 18O4. In 1863 I first operated successfully, using the j)lan here detailed, in a case, related further on, where a portion of the lower jaw, including two incisor teeth, had been removed by a direct blow from a capstan bar. Since then I have uniformly practised this plan. I'he instruments I now use, are the following:— Fig. I, PI. I ; the “ Handbit,” with cutting edges, right and left. Fig. 2, PI. I, shows the cutting edges ; fig. i exhibits the cutting edges with the right and left “ angles of relief.” 'I'he bit should have one-sixteenth of an inch diameter, and be three inches in length of stem. The hole drilled by it will thus allow one twenty-fourth of an inch silver annealed wire to pass easily. Fig. 3, PI. I ; the Key for coiling the wire ends, with slit. The slit should be wide enough to receive the wire easily, and should widen slightly towards the extremity. This key is cut out of a one-eighth inch steel rod. Fig. 4, PI. I ; The tube, with oblique orifice, to receive and guide the wire, when withdrawn through the bone or between teeth. Fig. 5, PI. I ] the watchmakers’ broach, to broach between teeth. It is well also to have at hand a similar broach, bent to a right angle at half-an-inch distance from the point.
