 ... consequence of the whirling motion of the earth about its axis, the parts near the equator, which have the greatest velocity, acquire thereby a greater distance from the centre than the parts near the poles.

...Hill militates against the supposition, that it was intended to represent the earth. It is thus said, that the form of the earth is that of an oblate spheroid, whilst this hill presents the form of a cone to the eye. The objection, when duly considered, carries... | |
