So soon as the skin is divided, the ether begins to exert on the nervous filaments the double action of cold and of etherization : so that the narcotism can be extended deeply to any desired extent. Pure rectified ether used in this manner is entirely negative ; it causes no irritation, and may be applied to a deep wound, as I shall show, without any...
