150 HUNTER ON THE TEETH.
and it was in the Upper-Jaw of a child about nine months old
there were the bodies of two Teeth, in shape like the Cuspidati,
placed directly behind the bodies of the two first permanent
Incisores ; so that there were three Teeth in a row placed behind
one another, viz., the temporary Incisor, the body of the per-
manent Incisor, and that supernumerary Tooth. The most re-
markable circumstance was, that these Supernumerary Teeth were
inverted, their points being turned upwards, and bended by the
bone which was above them not giving way to their growth, as
the Alveolar process does, (o)
It often happens that the Incisores and Cuspidati, in the
Upper-Jaw especially, are so irregularly placed, as to give the
appearance of a double row. I once saw a remarkable instance
of this in a boy ; the second Incisor in each side was placed
farther back than what is common, and the Guspidatus and first
Incisor closer together, than if the second Incisor had been
directly between them ; so that the appearance gave an idea
of a second row of teeth.
(o) [Mr. Tomes observes that " Supernumerary teeth may spring up
during the second dentition in any part of the alveolar arch, and the
forms of such teeth may either resemble those of special members of the
normal series, or they may deviate from each of the recognised forms,
and assume a somewhat irregular conical shape, sufficiently characteristic
in itself to be at once recognised as that of a supernumerary tooth." (1)
He mentions a case in which there were as many as four supernumerary
teeth forming a group with the upper incisors and canines. Sometimes
supernumerary teeth are not distinguishable from the normal forms. In
other instances the crowns are of a conical form, or the point may pre-
sent a depressed or otherwise irregular surface. Hunter is mistaken in
saying that they only occur amongst the incisors and canines. They are
occasionally observed amongst the molar series. Sometimes they resemble
irregularly-formed wisdom teeth implanted externally to the normal
molars. At other times they are not distinguishable in form from ordi-
nary molars and bicuspids.]
