arteries and nerves to their substance, so, probably, does the
periosteum of the teeth transmit minute arteries aud nerves to
their fangs, for the preservation of their vitality. This is the
more probable, as the vitality of the fangs does not depend
upon the internal membrane, as we shall shortly prove. Every
tooth has an internal cavity in some respects, of the shape
of the tooth itself, lined with its proper membrane, to
winch an artery and a nerve are transmitted, forming, to-
gether with the veins, absorbents and cellular substance, the
pulp or internal membrane of the tooth, which adheres firmly
to the walls of the cavity. Its blood-vessels are numerous,
and large enough for the circulation of the red particles of the
blood ; for in cutting off the crown of a carious tooth, the pulp
of which is living, a small quantity of blood is usually dis-
charged ; also, in removing the carious and dead portions of
teeth, much decayed, for the purpose of plugging, the part
near their internal membrane, will often appear reddish, from
the blood-vessels of this membrane, shining through the thin
layer of bone. If an aching tooth be extracted and split
asunder, the pulp will always appear red and inflamed, and
the vessels so large, that they can be distinctly seen, ramifying
through the whole pulp.
" A large quantity of blood is distributed to the teeth ; blood
carries with it the principle of nutrition, and is sent only to
those parts where renovation is necessary ; for what other
reason then, but to impart some principle of nutrition, can so
much blood be sent to the teeth." Fox on the Teeth. Part II,
page 34.
" The phenomena," says Mr. Charles Bell, " displayed in
the formation, adhesion, and diseases of the teeth, show them
to be possessed of life, and they have a correspondence or
