Note 479 — THE THIRD VOYAGE NORTH-WARD TO THE KINGDOMES OF CATHAIA and China, in Anno 1596.

With 7′,5 for refraction, and—7° 10′,8 for the sun’s declination, the above observation gives 76° 8′,7 for the height of the Pole. If no allowance was made at the time for the sun’s semi-diameter, 16′ will have to be deducted, which will make the true latitude to be 75° 52′,7. ↑
