  We consider the equation of motion in the gravity sector that arises from the
non-linear realisation of the semi-direct product of E11 and its first
fundamental representation, denoted by l1, in four dimensions. This equation is
first order in derivatives and at low levels relates the usual field of gravity
to a dual gravity field. When the generalised space-time is restricted to be
the usual four dimensional space-time we show that this equation does correctly
describe Einstein's theory at the linearised level. We also comment on previous
discussions of dual gravity.
