    Provisional Fitkin s Improvements in Instruments for Fairacting Teeth. acting directly upon the tooth, and is conveniently contrivod for resting on the bridge piece, for which purpose I prefer to shape it with an orifice near the end, by which it is passed over the end of the bridge piece, and thereby con¬ nected therewith. The compound instrument is generally applied by so placing the first portion or instrument that the rest piece may bear, rest, or 5 press against the gum on one side of the jaw, while at the opposite side thereof the second portion or instrument is rested on the bridge piece working thereon as a lever on its fulcrum, and so acting upon the tooth; in fact, both appliances or instruments may be worked as levers in some cases, the handles being moved in antagonistic or opposite directions. The first instrument may 10 be said to be formed with two fulcra, namely, the rest piece and the place of contact with the second appliance. Instead of the two instruments that constitute my apparatus being separate or detached, as above described, I sometimes modify the contrivance by jointing, connecting, or attaching them together, their arrangement being in 15 other respects similar to what has been before stated.
