Book excerpt: Excerpt from Untrodden Ground in Astronomy and Geology: Giving Further Details of the Second Rotation of the Earth and of the Important Calculations Which Can Be Made by Aid of a Knowledge Thereof IN the following pages some further details will be given of the second rotation of the earth, and the important facts that are revealed by a knowledge thereof. The reader' who wishes to become conversant with this hitherto unknown movement, is recommended to investi gate this second rotation by itself; to omit, for the time being, all notice of the earth's daily rotation, and Of its annual revolution round the sun, and to examine the details of a slow second rotation of a sphere. It will then be manifest that, whilst the poles of rapid rotation are carried over small arcs by the second rotation, every other point on the surface of the sphere will be carried over arcs by the same movement; but these arcs will differ not only in extent, but in direction, according to their positions relative to the poles of the second axis of rotation.
