The dynamical theory used to obtain the masses of the uranian satellites from their orbital precession rates contains a fundamental error. The masses can be derived from the precession rates, but a correct analysis of the available data must allow for the fact that the eccentricities, inclinations and precession rates all vary considerably with time, due to mutual secular perturbations.
