it almost always occurs. The two are, in fact, so much alike
that their chemical separation is by no means an easy task. The
specific gravity of nickel is given at 8.357 when cast, and
8.729 if rolled; in this and in atomic weight it differs little
from cobalt. Nickel and cobalt are also closely allied to iron,
which they resemble in color, although slightly whiter than that
metal, the former having rathe
