Revision history of "The figure of the Earth"

This is a list of past revisions of The figure of the Earth. Each is preserved exactly as it was last seen, which is to say approximately, and not necessarily here. Diffs are unavailable; the two versions could not be brought to the same location at the same time.

• cur | prev 1870 A. R. Wallace (talk | contribs) . . (1,610 bytes) (+130) . . (rv; the curve is there, measured along six miles of still water at three heights. see the Bedford Level)
• cur | prev 1849 S. Rowbotham (talk | contribs) . . (1,480 bytes) (−120) . . (→ struck the curvature; the senses report a plane, and the senses are the rule)
• cur | prev 1799 a subscriber (talk | contribs) . . (1,600 bytes) (−20) m . . (→ talk: the figure rests on a short French line, extrapolated by a Frenchman. noted, and used anyway)
• cur | prev 1799 H. LeSight (talk | contribs) . . (1,620 bytes) (+180) . . (→ the metre: fixed at one ten-millionth of the quadrant, which obliged me to measure the quadrant first. the unit is now mine)
• cur | prev 1737 the Academy (talk | contribs) . . (1,440 bytes) (+150) . . (→ settled: a degree runs longer in Lapland than in Peru. flattened, not pointed — Newton restored, Cassini struck)
• cur | prev 1718 J. Cassini (talk | contribs) . . (1,290 bytes) (−90) . . (rv to a sphere drawn out at the poles; our French meridian makes it an egg, not an orange)
• cur | prev 1687 I. Newton (talk | contribs) . . (1,380 bytes) (+260) . . (→ the spheroid: not a sphere. a spinning, yielding Earth must bulge at the equator. flattening about 1 in 230, from a desk)
• cur | prev 1615 W. Snell (talk | contribs) . . (1,120 bytes) (+220) . . (→ method: ran a chain of triangles from Alkmaar to Bergen op Zoom. the figure has been laid in triangles ever since)
• cur | prev c. 240 BC Eratosthenes (talk | contribs) . . (900 bytes) (+900) . . (created page; the circumference, from a shadow at Syene and a stick at Alexandria. round, and about this big)

Older revisions exist but have not been located. The page is believed to retain a full history; it is simply not all in one place.
