The rectangular caxitv (e) con-tains the screw. (Fig. ). The tongue-spatulas are attached to thepegs (g). The screw (h) holds the epiglottis-spatula. attachmentwhich holds the mouth open, a sort of mouth-gag also is supplementaryto the suspension-hook (compare Fig. ). It is provided with a tooth-plate (k) which rests against the upper incisors. This tooth-plate is so. arranged, (). that it may be extended or shortened. Thisis accomplished by means of the screw (h). The screw-end of theliandle is inserted into the part (d) of the hook-si)atula, and is securelyfixed there by means of the screw (f) as shcjwn in hig. ]0(). By turn-ing the screw (f) the handle (!) may be variously placed. In this man-ner the patients mouth may be opened as wide as seems desirable. 4—Till- :-sp.\\. The tongue-spatula has in the course of lime undergniie many modi-fications, but we now possess a model which meets all demands. Inits construction 1 have adopted the alterations wliich Albrecht proposed. 138 SUSPEXSIOX LARVNGOSCOPV.
