    potent reason than the one usually given, to be explained later on. So now we have our upper rimsbitesplate to represent our teeth when set up. It will be our guide, too, in setting them up. Xext we '11 do the same thing in our lower case. As in the upper, we '11 get, again, our rim*plate impression from our lower model (or from the mouth, as for that). But we must see that it will stay dozen—^^somewhat, at least— to its place in the mouth. This is important and almost essential in getting an ante^test bite. If tlie mouth has an alveolar ridge, it will suck down; but, if not, we must other- wise provide for its down^stay. In this flat, flabby case, we must have a substitute for suction in our lower bitc'plate. HEAVY LOWER BITE=PLATES. Here icatch mij most valuable little invention ever made in bite-taking-. We '11 take the im- pression of our lower model with heavily tceight- cd molding compound—that is, compound with fine bird=shot well kneaded into and through it; and even with small bars and rolls of lead also worked into the rim, if necessary, to hold it down to place. TRIM LOWER BITE^RIM FOR LENGTH OF LOWER TEETH. AVe 're now ready for trimming and fitting our lower bite-plate to the up])er one. But we '11 reverse the order and get tlie sliow=lengi:h for the teeth first. Don't forget that in the up- per case we first got the fullness and then the show=length; but in the lower case it is exactly reversed. And now, doctors, here is the tvay we get the lower bite^rim to the showslength of the
