lie will succeed or fail just IN proportion
rs he has thr ability to observe the hun
deeds ormodcls which are pcrpetually be-
fore him, and rs he has the further and
rarer ability TO apply his observation to
the special cases that are in his labara-
tory. Imitation of nature is the the rule,
limitations of art and individual ncapaci-
tv make exact observance of this rule
comparatively rare. We replace the six
teen teeth with only fourteen and often
make them shorter, and every way small
er than the natural organs, We do not
make the grinding surfaces intcrlock with
such deep cusps Us in nature. At one
time, we cannot avoid an unnatural full

Notwithstanding these and many other
disadvantages, the perfection OF the
dcnto- ceramic art is such that skilled
artist, who is qGck TO observe what ma
ture requires, can, in the majority of cases
falling under his care, supply the lost
dental organs with great accuracy, and
preserve that higher order Of beauty
which grows out of the harmony of his
work with the expression Of the face and
entire person. But no dentist can give
his work this kind Of beauty who does

have found in my practice one Of the
most difficult things to overcome in put
ting up block teeth is to prevent that
striking artificial look owing to the regu
ular form, as l have before intimated, the
fairness of tho teeth and gums. How
ever there are few devices that we can
resort to, such as grinding off the cutting
edges in different ways SO as to give a
