ATOMIC STRUCTURE
which
equation,
with the
exception
of
the
expression
for
the
co-efficient,
agrees
with
(15).
By comparison
we
obtain
32
=
w7.....(20)
This
equation
signifies
that
of
the
energy
constituting
matter
three-quarters
is to be
ascribed
to the
electromagnetic
field,
[25]
and
one-quarter
to
the
gravitational
field.

Concluding
Remarks
The
above
reflexions show
the
possibility
of
a
theoretical
construction
of
matter out
of gravitational field
and
electro-
magnetic field alone,
without the introduction
of
hypothetical
supplementary
terms
on
the lines
of
Mie’s
theory.
This
possibility
appears particularly promising
in
that it
frees
us
from
the
necessity
of
introducing
a
special
constant
A
for
the
solution
of
the
cosmological problem.
On the
other
hand,
there
is
a
peculiar
difficulty.
For,
if
we specialize (1)
for
the
spherically
symmetrical
static
case we
obtain
one
equation
too few
for
defining
the
guv
and
duv,
with
the result that
any
spherically
symmetrical
distribution
of
electricity
appears
capable
of
remaining
in
equilibrium.
Thus the
problem
of
the constitution
of
the
elementary quanta
cannot
yet
be
[26]
solved
on
the immediate
basis
of
the
given
field
equations.
