[55]If
[eq. 79]
is
a
scalar,
[eq. 80]
should
be
reducible
to
[eq. 79].
[56][Eq.
81]
permits n
in
[eq. 80]
to
be
put
in
front of
a/axo
to yield
[eq. 82].
[57]Einstein
assumes
that the transformation differs
only infinitesimally
from the
identity
and
concentrates
on
terms
in
which
pua
and
nav
are
differentiated
at
least
once.
