    FORMATION OF THE TEETH. When the rudiments of the teeth are firsf discoverable, they are small gelatinous or pulpy bodies, enveloped in thin membra- nous sacks, and arranged in a sort of exca- vation or groove in the jaw, which at this time is but imperfectly formed. Bony fibres then shoot across this groove, and separate it into distinct cells, each of which contains its proper pulp, or embryo tooth, invested in its membrane. At the time of birth, the formation of the temporary teeth has generally so far advanced, that the pulps have attained their full size, and ossification has extended over their surfaces in such a manner as to form complete bony shells of the size and figure of the crowns of the teeth; and the pulp of the first permanent grinder, on each side of both jaws, has ac- quired a considerable magnitude. After this the pulps begins to elongate, in order to form the fangs, and the process of ossification is continued for the same purpose till they are completed.
