In regard to the of platinum for dental purposes
Prof Chace, Professor of Chemistry in Brown Unversi

BRowN UNIVERSITY, April 49, 1852.
GENTLEMEN To your inquiry whether platinum
may be enEoyei with safety health In dental opera
tions have no hesitation in giving affirmative an.
It's one OF the most nattackabe substances in
nature. Although resembling silver in appearances il
has twice the density OF that metal, and differs remar
kably from il in nearly all its ysca and chemical prop
critics. Only two of the known acds-the nitro muriat
ic and the nitro hydrU-uoric-h any effect upon it,
both of which dissolve gold with even greater facility
Neither platinum gold, when pure, are at all acted
upon by the fluids of the mouth, and consequently can
exert no preJudici influence upon the system when used
in the filling or fastening Of teeth. AS the former, how.
ever, is found in commerce and the unadutera
ted state only while the latter is with alloy ed in
every proportion with the baser METALS the employ
ment Of platinum may always be regarded safer than
the use ofg gold, unless has come Immediately from
the hands of the assayist Yours, &C,
