mineral
oil, or
natural
oil, a dark brown or

which,
at
certain
points,
exists
in the upper
strata
of the
earth,
from
whence
it is
pumped,
or
forced
by
pressure
of the gas
attending
it. It
consists
of a
complex
mixture
of
various
hydrocarbons,
largely
of the
methane
series,
but may vary much in
appearance,
composition,
and
properties.
It is
refined
by

etc. It is
isolated
as a soft, waxy,
white,
unstable
metal,
so
readily
oxidized
that it
combines
violently
with
water,
and to be
preserved
must be kept under
petroleum
or some
similar
liquid.
Sodium
is used
combined
in many
salts,
in the free state as a
reducer,
and as a means of
obtaining
other
metals
(as
magnesium
and
aluminium)
is an
important
commercial
product.
