Many years ago JH questioned him about the calculation of the perturbations in an inclined orbit, the satellites of Herschel [Uranus] for example. Has only recently seen the light. Is now confident that he can calculate the perturbations of any planet in any orbit. Gives details and would be glad of JH's comments.
