    teeth. In fact, one has oftentimes been made to do this for years, without having been attended with any un- pleasant effects whatever, and in the insertion of a single tooth in the front part, or two or even three on the side, of the mouth, it is seldom necessary to apply more than one clasp. But in this case, the clasp should be fixed to a bicuspis or first or second molaris. After the clasps have been fitted to the teeth, they should be connected to the plate, while on the model, by means of two pieces of wax, softened until they are about the consistence of putty. The plate and clasps should now be taken off, without altering in the least their rela- tive position, and placed on a piece of paper with the concave side of the plate upwards, then plaster of Paris, prepared in the manner as before described, poured over it and the clasps. As soon as this becomes hard, the piece may be lifted from the paper, and the wax taken off, when, if there be any apertures between the clasps and plates, they should be filled either with gold foil or small pieces of plate. Finely ground borax (sub borate of soda) mixed with water, until it is of the consistence of cream, should now be applied with a camel's hair pencil, to the parts to be united, and after which, several small pieces of fine gold solder. It should next be placed on a piece of charcoal and the flame of a spirit or oil lamp be thrown upon it with a blow-pipe, until the solder fuses and unites the clasps to the plate. It is much better to solder the clasps to the plate in this manner than to do it on the plaster model, as that will be afterwards needed, and is liable to be injured by the intense heat necessary to be applied to fuse the solder. The clasps having been soldered to the plate, the piece should be placed in diluted sulphuric acid, and allowed to remain about twenty or thirty minutes for the purpose
