Reading edition
The declination here given is that of April 19th. The corrected calculation for the 18th, with refraction 2′,0 and declination + 10° 50′,1, gives 75° 42,1; or 75° 26′,1, if the sun’s semi-diameter has to be deducted. On April 19th, the declination was + 11° 10′,1, whereby the height of the Pole would be 76° 2′,1; or, deducting the sun’s semi-diameter, 75° 46′1. ↑
