... appears , then , that the influence of the centrifugal force is most powerful at the equator , not only because it is actually greater there than elsewhere , but because its whole effect is employed in diminishing gravity , whereas , in ...

... appears from theory , that a horizontal line passing round the earth through both poles must be nearly an ellipse , having its major axis in the plane of the equator , and its minor axis coincident with the axis of the earth's rotation ...

... appears that the length of the degrees increases from the equator to the poles , nearly in proportion to the square of the sine of the latitude ( N. 127 ) . Consequently , the convexity of the earth diminishes from the equator to the ...
