768 ORTHODONTIA AS AN OPERATIVE PROCEDURE.

one first used by the autlior in 18S0. It consists of a vulcanite cap fit-
ting the labial and i)art of the lingual surfaces of the anterior teeth (Fig.
767). In this is imbedded a steel or German-silver wire, about No. 12,
so that the ends will protrude between the lips at the corners of the
mouth. These ends are bent into hooks, and extended far enough so
that elastics from them to the cap on the back of the head will not touch
the cheeks. These extended arms may be bent to conform to the curve
of the checks, but should not touch them. The cloth cap is such as any
seamstress can make easily, and extends forward above and below the
ear. On these projecting ends are sewed dress-hooks. For power use
round or flat elastic cord. Tie a knot in one end, place it in the hook
