Any desired size may thus be obtained; 212 OPEEATITE DEXTISTEY. the lower down upon the instrument the nick is made the larger the hole ;the tighter the dam is drawn the smaller the hole will be. The wTiter has used this method many years, to the exclusion of allothers, and with perfect satisfaction. Fig. 308 shows the relative size of holes adapted to (1) incisors andcuspids, (2) bicuspids, (3) molars. The depressed rubber dam (Fig. 309) Fro. 308. Fig. 309.
