Dr. Price presented two very ingenious appliances; the first consisted of an instrument designed for putting in guttapercha fillings made after the principle of an electric cautery. It was suggested to the doctor that the same principle could be utilized in the making of wax spatula. The second consisted of an appliance to the hand-piece of a dental engine for the purpose of blowing a constant stream of warm air into the cavity while excavating. A stream of air is forced over a small incandescent lamp in this way heated at the same time light is thrown into the cavity.
