Note 11 — Chapter II
Reading edition
This observation, made without the assistance of an ephemeris, or tables of declination, can only be considered as an approximation. It however proves that Sannack and Halibut island is the same, the latitude of that island, as ascertained by captain Cook, being 54 deg. 27 min. As the observation was made about the time of the equinox, the correction for declination might be estimated within a few minutes.
