  We calculate the energy distribution of a dyonic dilaton black hole by using
the Tolman's energy-momentum complex. All the calculations are performed in
quasi-Cartesian coordinates. The energy distribution of the dyonic dilaton
black hole depends on the mass, electric charge, magnetic charge and asymptotic
value of the dilaton. We get the same result as obtained by Y-Ching Yang,
Ching-Tzung Yeh, Rue-Ron Hsu and Chin-Rong Lee by using the Einstein's
prescription.
