Extract

The object of this paper is to show that librations of the Earth follow conditions that are prescribed by nutations. The poles of rotation, excitation and inertia are treated as moving within a system that has approximately constant speed and direction relative to the Conventional International Origin. Applied excitations are presumed to cause other excitations, part forming at once and part forming progressively.
