Early (first?) offprint of George Biddell Airy's "Figure of the Earth". According to Worldcat: "Extracted from v. 5 of Encyclopaedia metropolitana, ed. by Edward Smedley [and others], 1817-1845." Airy signs off at the end of the article: 'G.B. Airy, Observatory, Cambridge, August 17, 1830.'From Wikipedia: "In 1830, Airy calculated the lengths of the polar radius and equatorial radius of the earth using measurements taken in the UK. Although his measurements were superseded by more accurate radius figures (such as those used for GRS 80 and WGS84) his Airy geoid (strictly a reference ellipsoid, OSGB36) is still used by Great Britain's Ordnance Survey for mapping of England, Scotland and Wales because it better fits the local sea level (about 80 cm below world average).
