Perturbation of the perihelion distance q of long-period comets by the galactic tidal force is calculated. It is shown that the maximum perturbation is suffered by those with i (inclination) close to 50 to about 60 deg and not by those with i close to 90 deg, contrary to the prediction of the first-order perturbation theory. The dependence of the perturbation of q upon i is compared with the distribution of the inclinations of observed long-period comets, and it is shown that the latter is not consistent with an isotropic cloud of comets perturbed by the galactic tide alone. A close stellar encounter is unlikely to be an external disturbance. It is argued that giant molecular cloud is the most likely mechanism of the external disturbances.
