“ Now if we imagine a pendulum suspended from such an altitude, and in such a position, that one extremity of its line of oscillation shall be supposed to reach to London and the other to Edinburgh; and if we imagine the ball of such pendulum to be drawn towards, and retained over London, it is clear that, so long as it remains in that situation, it will share the velocity of London, and rotate with it. But if it be set at liberty it will immediately begin to oscillate between London and Edinburgh, retaining, it is asserted, the velocity of the former place. ”
