They shouldhave fine teeth along the edges where the bands and tapesbear to prevent slipping, and small holes every half-inch tohold the strings, lacing, &c.

The tape strings pass from the cap inside and under theupper wings, then up between them and the tape lacings(tig. 23) which keep the strings from slipping, to the capwhence they started. The mental band passes up betweenthe sides of the lower jaw and the wings, where it is tied bythe strings, which pass through the holes. The band iscut off to show this ; but when worn it should be turneddown on the outside and pinned just below the wings. Theneck strap should be sewed to the mental band on one sideand pinned on the other, and worn tight enough to keep theband from slipping forward over the chin. The jaw and splint are supported by the cap in front ofits centre. This is counterbalanced by the elas
