The T.E. scalar and the T.M. scalar whose derivatives yield the
respective vector potentials Eqs.(10) and (12) can be
related to Righi's magnetic ``super potential'' vector
and Hertz's electric ``super potential'' vector
[#!Phillips!#]. Indeed, if is the
T.E. scalar and is the T.M. scalar, then these scalars are
simply the -components of the corresponding super potential vectors

In fact, subsequent to Hertz's 1900 and Righi's 1901 introduction of their super potential vectors, Whittaker in 1903 showed that the Maxwell field can be derived precisely from our two gauge invariant scalars and [#!Phillips!#].
