    When the rudiments of the first or temporary teeth become so far advanced as to be well defined in form, the membranous sac of each sends forth a new sac, like a minute bud by its side. These new little sacs, are the germs of the permanent teeth which are to succeed the temporary ones, just as new buds succeed the old leaves of a deciduous foliage.- And as these sacs increase in size, the sockets of the tempo- rary ones become enlarged, and small niches, or recesses, are formed in the internal plates or partitions forming the sockets before described. These niches increase in capacity in proportion with the growth of the new sacs of the perma- nent teeth, until they gradually form new sock- ets, within the old ones, around them all. There is, however, an orifice left between the sockets, through which the membranes of both sets of teeth continue to be connected, and which are supplied by the nerves and vessels, common to both, running through the canal beneath them. But there is much reason to suppose that the new teeth flourish, by means of this connection, at the eventual expense of the old ones, for after the latter have fulfilled their temporary functions, their membranes, and even theukvery roots, have wasted away, and
