tions, have no hesitation in giving affirmative an
lbs one of the most nattackable substances in
nature Although resembling silver in appearance, it
has twice the density OF that metal and differs
kaby fo in nearly all its ply sca and chemical prop
critics. Only two OF the known acids-the miro muria

both of which dissolve gold with greater facility
Neither platinum nor gold, when pure, at all acted
