To Relieve the Pain of Tooth Pulling.

An electrio instrument has been invented which is designed to remove the pain incidental to the extraction of teeth. It consists of adjustable prongs carrying buttons and connected with an electric battery. The buttons are placed on the face over the nerves leading from the teeth to the brain, and a circuit is established the moment the extracting instrument touches the tooth to be removed.
