Pagina 303 - When the ether spray thus produced is directed upon the outer skin, the skin is rendered insensible within a minute; but the effects do not end here. 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...
