10) The London and Northwestern Railway forms a straight line 180 miles long between London and Liverpool. The railroad’s highest point, midway at Birmingham station, is only 240 feet above sea-level. If the world were actually a globe, however, curving 8 inches per mile squared, the 180 mile stretch of rail would form an arc with the center point at Birmingham raising over a mile, a full 5,400 feet above London and Liverpool.

Can someone make me understand of Curvature feet calculation which is mentioned in several proofs. As in 71 number proof ( or several other distanced based proofs ) That the Observer distance is 60 miles sea-level from Chicago buildings which should be 2,400 feet below the horizon. As per Nasa earth curvature goes down 8 inches per mile. 72 inches(6 feet) and 60 miles contain 60 x 8 = (480 inches) that is equal to (480/12) = 40 feet. How does it count to 2,400 feet?

97.) Mr. Hind, the English astronomer, says – "The simplicity, with which the seasons are explained by the revolution of the Earth in her orbit and the obliquity of the ecliptic, may certainly be adduced as a strong presumptive proof of the correctness" – of the Newtonian theory; "for on no other rational suppositions with respect to the relations of the Earth and Sun, can these and other as well-known phenomena, be accounted for." But, as true philosophy has no "suppositions" at all – and has nothing to do with, "suppositions" – and the phenomena spoken of are thoroughly explained by facts, the "presumptive proof" falls to the ground, covered with the ridicule it the dust of Mr. Hind's "rational suppositions" we are standing before us a proof that Earth is not a globe.

**144) Pictures of the Moon appearing upside-down in the Southern hemisphere and right-side up in the North are often cited as proof of the ball-Earth, but once again, upon closer inspection, provide another proof of the flat model. In fact, time-lapse photography shows the Moon itself turns clockwise like a wheel as it circles over and around the Earth. You can find pictures of the Moon at 360 degrees of various inclination from all over the Earth simply depending on where and when the picture was taken.**

`Astronomers tell us that, in consequence of the Earth's "rotundity," the perpendicular walls of buildings are, nowhere, parallel, and that even the walls of houses on opposite sides of a street are not! But, since all observation fails to find any evidence of this want of parallelism which theory demands, the idea must be renounced as being absurd and in opposition to all well-known facts. This is a proof that the Earth is not a globe.`
