Biot and Arago, it is stated that the light of a powerful lamp, with good reflectors, was placed on a rocky summit, in Spain, called Desierto las Palmas, and was distinctly seen from Camprey, on the Island of Iviza.
In the account of the trigonometrical operations in France, by M. 43, A, B, C, and D, D, represent the same points respectively as in fig.
Paul's cross B, Shooter's Hill and D, D, the datum line-the Trinity high water mark. 42 and 43, will show the differenceīetween the theory of rotundity and the results of actual survey. The highest point of Hampstead Hill is 430 feet, which we find, on making the proper calculation, would be 78 feet below the summit of Shooter's Hill whereas, according to the Ordnance Survey, and as may be proved by experiment, the three points are in the same direct line again demonstrating that the earth is a plane. Paul's cross would be 32 feet, and Hampstead Hill 96 feet. "levelled" theodolite would be a tangent, below which St. If the earth is a globe, the line of sight from the Paul's Cathedral is 7 statute miles, and from St. The altitude of each of these points is 412 feet above the Trinity high water mark, at London Bridge. Paul's Cathedral, and fall upon a part of Hampstead Hill, the altitude of which is the same as that of Shooter's Hill. If a good theodolite is placed on the summit of Shooter's Hill, in Kent, and levelled, the line of sight, on being directed to Hampstead Hill, will cut the cross on St. Sacred Texts Earth Mysteries Index Previous Next Experiments Demonstrating the True Form of Standing Water, and Proving the Earth to be a Plane: Experiment 14 Zetetic Astronomy, Earth Not A Globe: Chapter II.
