826 Whiston (Longitude 1721, 49) zufolge betrug die Neigung der Magnetnadel in London 1676 73° 30 ' und im Jahr 1719 73° 45 ' mit einer gewöhnlichen bzw. 75° mit einer nach Fatios Angabe (ebd., 6 f.) tarierten Inklinationsnadel.

826 74° Neigung der magnetischen Nadel entsprechen ungefähr dem Mittelwert der von Graham (Observations 1725, 334 – 336) für Anfang 1723 angegebenen Messungen.
