Hewitson went "to hear a person styled 'Parallax' give a lecture in Institution Avenham". The lecture argued that the moon does not cause the tides, that the moon is self-luminous, that "the earth is a plane", and that the earth would finally be destroyed by fire. His verdict: "He seemed honest & intelligent & ingenious." - Editor's note 107: this was the third of three lectures titled "Earth Not a Globe". Note 116: "Parallax" came back to repeat his three lectures, "admission sixpence, reserved seats one shilling" (advert, Preston Herald, 26 May 1866, p.1). The editor cites C. Garwood, "Alfred Russel Wallace and the Flat Earth Controversy", Endeavour 25:4 (2001) 139-43, for calling Rowbotham "a self-educated quack inventor" (that is Garwood's characterization). - Bearing: claims 1 and 3. This is an independent eyewitness record of Rowbotham's lectures and their content (moon self-luminous, tides not lunar) in 1866, from a neutral contemporary journalist. It shows the lecture series was a commercial tour.

The page gives a chronology of his experiments as stated in his books: winter 1837 observations on the frozen river; summer 1838 experiments 1 and 2 (Welches Dam to Welney Bridge); further experiments in 1844, 1849, 1856 and 1862; April 1870 experiment 5 (Welney Bridge to the Old Bedford Sluice Bridge, Salters Lode). It also lists Wallace 1870, Oldham 1901 and Lady Blount 1904. - Site geography: "'Welney Bridge' is the name frequently but wrongly used for the Old Bedford Bridge at Welney". The author notes that Rowbotham's statements are "somewhat inconsistent or confusing". He identifies a kink in the waterway ("the Gullet", south of Sutton Gault) that could hide a boat. He also notes that for the 1870 experiment Rowbotham used a different stretch, from a sluice bridge near Downham Market. - It describes a 2015 "re-enactment" by the Cambridge Archaeological Unit at an Environment Agency "Ousefest" day, which the author criticises. - Bearing: claim 1. Exact sites and sight lines matter for any recomputation of the curvature. The naming confusion also explains why Walsh's 1870 decision says "Welney Bridge and Welch's Dam" while Carpenter's report says Old Bedford Bridge to Welney Bridge. This is a local historian's analysis, not a primary record. - Manea Fen scholarship (search "Manea Fen" Rowbotham 1838 Bedford canal community Hodson "Working Bee"): S.
