GENTLEMEN To your inquiry whether platinum
may be employed with safety health in dental opera
tons have hesitation in giving an affirmative an
swer IT'S one of the inaitackabe substances in
nature Although resembling silver in appearance, il
has twice the density OF that metal, and differs remar-
kably from it in nearly all its steal and chemical prop
critics. Only two OF the known acds-the nl'ronurlat-
ic and the nitro hydrouorichave any effect upon 1t,
both of which dissolve gold will even greater faelly--
Neither platinum gold, when pure are at all acted
upon by the fluids of the mouth, and consequently can
exert prejudica influence upon the system when used
in the filing fastening of teeth As the former how
ever found in and the arts IN an unadultera-
ted state only, while the latter is met with aoyed in
every proportion with the baser metals, the employ
met Of platinum may always be regarded safer than
theuse of gold, unless has come Immediately from
tbe hands OF the assayist Yours, &C,
