The Einstein-Kur\ifmmode \mbox{\c{s}}\else \c{s}\fi{}uno$\stackrel{\mathrm{\ifmmode \check{}\else \v{}\fi{}}}{\mathrm{g}}$lu and the Einstein-Bonnor unified-field-theory equations for the time-independent, spherically symmetric electric and magnetic fields are reduced to an ordinary integrodifferential equation of the type previously solved by numerical methods. It is found that specifying the mass and charge of the electric monopole along with using Dirac's value for the magnetic charge is sufficient to determine the mass of the magnetic monopole in the Einstein-Kur\ifmmode \mbox{\c{s}}\else \c{s}\fi{}uno\ifmmode \breve{g}\else \u{g}\fi{}lu and the Einstein-Bonnor theories. The observed mass of the electron and the large (unobserved) mass of the magnetic monopole do not disagree with these unified field theories.
