Text: It is demonstrated, Section III, that if approach to the center of force, or the sun, is supposed by any predominance of the force of gravitation, unless some extraordinary intervening cause is supposed, the earth must continue to approach that center. It has not helped the matter any, nor shown any such added cause, by showing the necessary equality at all times, of the centrifugal with the centripetal force, or that the cause of approach toward the sun with increasing rapidity, must be by a continually-increasing rapidity, must be by a continually-increasing acuteness of angle of the opposed forces always of equal value. In either case, a system of exertion of force in one direction is shown; but no provision for a change, such as to produce a reverse direction, has been.
