naturally
assumed
a
geometrical

-
An
inorganic
body,
which,
by
the
operation
of
affinity,
has
assumed
the
form
of
a
regular
solid,
terminated
by
a
certain
number
of
plane
and
smooth
surfaces;
glass
of
a
superior
composition
and
manufacture;

-
Anything
congealed
like

smooth
surfaces;
any
natural
body
transparent
or
semi-

together,
as
an

-
The
regular
form
which
a
substance
tends
to
assume
in
solidifying,
through
the
inherent
power
of
cohesive
attraction.
It
is
bounded
by
plane
surfaces,
symmetrically
arranged,
and
each
species
of
crystal
has
fixed
axial
ratios.
