Local anesthesia is growing in popularity with the medical profession. Generally we have to rely on the ordinary hypodermic syringe for the application of the anesthesia, unless one is fortunate enough to own a Farr apparatus. In the use of the ordinary syringe much time is consumed in refilling, or even in the exchange of syringes. It was with the thought of avoiding this delay that I devised the syringe illustrated. The syringe refills itself from a container attached to the syringe and suspended conveniently from the wrist of the surgeon. In this way a small or large amount of the anesthetic may be injected accurately with the least effort. In the illustration, 7 and 17 indicate the outlet and inlet valves, 11, 15 and 16 the intake channel, and 20 the container for the supply fluid.
