Ivoryfrom the Tooth of the Hippopotamus.

We should select this, if we intend to use it, which has a
large proportion of enamel, and is of a fine clear colour, and
of a close, dense, compact structure, with a fine grain, not
coarse or cracked, and checked through its substance. It
does not require any particular preparation before working it,
nor is it necessary to put it in water, as it is not apt to split
when dry, or upon working it, if carefully managed.

Transplanting Teeth, fyc.
I have already said all that I wish to say upon this subject.
Those who wish for directions upon it, can consult Mr. Hun-
ter's remarks and directions upon transplanting teeth, &c*

section in.

OF THE MANNER IN WHICH ARTIFICIAL TEETH SHOULD BE
INSERTED IN THE MOUTH.

There are various modes of inserting artificial teeth in the
mouth ; some of which are very pernicious, and others very
useful and proper. Of these I shall mention but four, to wit
Firstly, with Ligatures.
Secondly, with Springs and Clasps.
Thirdly, with Pivots.
Fourthly, with Clasps alone.
