    other no'bite on it. Wlieii the plaster is hard, we '11 take the teeth out of the mouth, and, using compound or bees*wax instead of plaster, we '11 fasten them in the articulator; the plaster on the teeth being our articulating guide. In placing them in the articulator, we '11 be just as careful in the use of the face-bow, or measuring'Stick, as we were in articulating the bite in the first place, and for the same ex- plained reasons. (We '11 now go to the labora- tory, out of patient's sight.) When these finished dentures are in the ar- ticulator, we '11 remove the plaster from be- tween them, bring them together, and look un- der and see what has to be ground off. A few touches with tlie carborundum wheel, and the worst is off. Xow we '11 follow up with carborundum sand^paper, by sliding it be- tween the teeth until eacli one will touch its opponent, even to the holding of the thinnest tissue paper, if we so wish. But in this final grinding we mustn't neg- lect to give the lateral motion to the articu- lator, to wear the teeth off to the regulation lateral quid=chewing attrition. A STILL FINER LAST GRINDING TOUCH. A still finer last toucli may be made with carborundiun grit. Stick a strong piano'wire coil-spring firmly onto the extending point of the guide screw of the articulator, of a length to ])ush the teeth to about an inch apart. Then put ^a bumpswheel on your lathe s])indle and hold the articulator so the bumps will strike it on to]). The spring will open the jaws, and the bump (one or more) on the wheel will close them. Thus you '11 have a chewing^ machine to—chew too fast, if vou don't watch out.
