## Abstract

It is shown that Sachs's approach to the unification of gravity and electrodynamics brings nothing essentially new and is, in fact, equivalent to the already known forms of Einstein's equations. It thus follows that Sachs's ?gMaxwell equations?h do not represent the electromagnetic field and can be interpreted in purely gravitational terms.
