the
assumption
of
polarizing
forces
exerted
by
the electrical particle
on
the
neutral molecules
does not
suffice for the
explanation
of their small mobil-
ity, but that,
in
dry
air
and at normal temperature,
one
must
ascribe
to
the
negative
ions
a
diameter about twice
as
large, and
to
positive ions
one
about
three times
as
large
as
that ascribed
to
the neutral molecules.
For flames,
the author finds that it is
to
be
concluded
from
the
empirical
results that
the
mass
of the
negative
electricity carriers is
about
a
thousand times
smaller than that
of
the positive
ones,
and that the
mass
of the latter
equals
that of the
hydrogen
atom;
hence, the former
corresponds
to
cathode
rays,
the
latter
to
Goldstein
rays.
