eral a and whole in actual seruice which give
entire satisfaction, has adopted it in his practice, and IS
prepared to recommend lit public condolences the more
So from the unqualified expressions Of preference, and
confident of superiority over block Teeth on
gold plates by who have tried both Pure plati
used instead of gold the latter being necessarily
aoytd with silver and copper fuses too readily for the
purpose. Platinum is not acted upon by the fluids Of
the mouth consequently, is free from the metallic (gal-
vanc) taste oencompaned of in the of fine gold.
This method OF setting Teeth has been in operation in
this office tor several months but public notice has been
delayed to afford ample opportunity of comparing 1t
Thoroughly with every other known aud popular mode,
and Also not to excite public pecatioH without JUS
iable basis Its comparative advantages in the con-
structon oil half or whole sets, upon the atmospheric
pressure principle, will be demonstrated upon applica
ton. Among them are the following, viz

In regard to the of platinum for dental purposes

L., as follows:
Brown UNIVERSITY April is, 1852.
CONFERENCE.-THE your inquiry whether platinum
may be employed with safety health in dental opera
tons, have no hesitation in giving affirmative
1t one of the most inatackabe substances in
nature. Although resembling silver in appearance
has twice the density of that metal and differs
kably from it nearly all its physicaland chemical prop
critics. Only two fthe known acidshe niIro.muriat-
lie and the INTERCHANGEABLE any effect upon it,
both of which dissolve gold with greater facility.
Neither platinum nor gold when pure, all acted
upon by the fluids of the mouth, and consequently
exert no preudcia influence upon the system when used
in the filling or fastening Of teeth. As the former how
ever is found 10 coTamece and the unadutera-
ted state only while the latter is with allowed in
every proportion with the baser metals, the employ
ment Of platinum may always be regarded safer than
the of gold, unless 1t has Immediately from
