Note 552 — THE THIRD VOYAGE NORTH-WARD TO THE KINGDOMES OF CATHAIA and China, in Anno 1596.
Reading edition
The corrected calculation, with declination + 17° 44′,9 and refraction 12′,2, will give 75° 47′,9. If the sun’s lower edge was observed, 16′ will, in this instance, have to be added to the latitude, which thereby becomes 76° 3′,9. ↑
