  The effect of a barred potential (such as the one of the Milky Way) on the
galactic orbits of forty-eight globular clusters for which absolute proper
motions are known is studied. The orbital characteristics are compared with
those obtained for the case of an axisymmetric galactic potential. Tidal radii
are computed and discussed for both the better known axisymmetric case and that
including a bar. The destruction rates due to bulge and disk shocking are
calculated and compared in both galactic potentials.
