GENTLEMEN:-Tn your inquiry whether platinum
may be employer with safety health in dental opera
t0ns, have no hesitation in giving Affirmative
It's Of the most nattackable substances in
nature Although resembling silver in appearance,
has twice the density of that metal and differs remar
kaby from it in nearly all its physical and chemical prop
critics. Cnly two Of the known acids-the niro.murat-
c and the nitro ydru-iuoric- any effect upon il
both of which dissolve gold wi even greater facility
Neither platinum gold when pure, all acted
upon by the fluids Of the mouth, and consequently can
exert preudcal influence upon the system when used
IN the filing fastening Of teeth. As the former how
is found in and the unadultera
ted state only while the latter is met with alleged in
every praporton with the baser metals, the employ
ment Of platinum may always be regarded safer than
the OF gold, unless IL has Immediately from
the nan Of the assayist. Yours, &C.
