Professor Stoerk, of Vienna, also, when laryngoscopy wasquite in its infancy, contrived a porte-caustique in which the caustic re-mains concealed till brought to the part desired to be touched, when, bypressure on a spring in the handle, it is made to protrude. My laryngeallancet is provided with a small piece of aluminium wire, which can befitted on in place of the cutting blade; in this way it becomes a guardedporte-caustique. The nitrate of silver is attached to the wire by fusionin the way already described. Bes
