    which it is not possible to obtain with ordinary soldered work. Then with silicate of soda paint the joints, to keep the rubber from forcing in where it would show after vulcanizing. Flask, vulcanize, and finish as usual. The rubber may be allowed to project beyond the edge of the plate on the labial surface, if desirable, and this in many cases will be found to be very satisfactory, as by such means the rubber may be left thick near the alse of the nose, when the loss of the cuspids may necessitate a support to the soft parts adjacent, and which in this manner can be readily supplied. If the rubber extends upward so far as to irritate the parts, a few minutes will suffice to make the necessary alteration. When celluloid is used for attaching the teeth, the pala- tal portion of the blank should be sawed out, leaving only the part covering the alveolar ridge, which may be trimmed away so that there will be but little excess of material. For lower plates the ordinary full lower blank is used, trimming to suit the case. After preparing the blank in this manner, the manipulations are the same as for a celluloid base. The teeth being arranged upon the metal plate and the contour restored in wax as desired, fill the plate with plaster, and also the lower section of the flask. Imbed the plate in this, forming the line of sepa- ration at the edge of the wax rim, thus allowing the pala- tal portion of the metal to be covered with plaster. After the other section is formed, separate as for vulcanite.
