are sunk (while the paste remains soft) two cramps, made
with platina wire prepared for this purpose. It'is also neces-
sary, that the tooth may be more susceptible of being firmly
soldered, to implant a third cramp a little lower than the two
first, and in the middle of the groove upon the side of the
triturating surface.
After this manner as many teeth may be moulded as are
wished.
They are left to dry in their moulds : they may then be
