The analog of the Lorentz force law as described in Eqs. (36) of "Original Article: May 7, 1999" on this website should be replaced by,
where 
is the
permutation or Levi-Civita symbol,
, and
. The
are the components
of the velocity four-vector of the point source charge that creates the field,
, and the
are the components
of the velocity four-vector of the point test charge,
. These equations
give rise to the terms
which we interpret
as
where m is the mass of the test charge. Equating terms in Eqs. (2) and integrating we get for the mass,
or
where 
and
are constants
of integration and
is the electric
potential created by the other charge.
