Topsails, and obliged us to strike Topgallant Yards. At 8 a.m. wore ship
and stood to the Southward. Wind South-West and West; course South 68
degrees 45 minutes West; distance 44 miles; latitude 44 degrees 9 minutes
North, longitude 10 degrees 20 minutes West; at noon, Lizard North 29 1/2
degrees East, 138 leagues.

Sunday, 4th. Fore part fresh Gales and Clear; remainder light Airs and
Calm. At 6 a.m. Cape Finister bore South by West 1/2 West, distance 10 or
11 leagues. Loosed all the Reefs out of the Topsails, and got Topgallant
Yards across. Wind Westerly, Calm; at noon, Island of Cyserga,* (*
Sisarga, near Coruna.) East-South-East 3 leagues.

Monday, 5th. Light breezes and Calm all these 24 hours. At 2 p.m. had an
Observation of the Sun and Moon, which gave the Longitude 8 degrees 42
minutes West from Greenwich. At 6 Cape Finister bore South by West 1/2
West, 6 Leagues. Variation of the Compass per Azimuth 18 degrees 42
minutes West. At Noon, Cape Finister South by East, distant 4 leagues;
latitude observed 43 degrees 4 minutes, therefore Cape Finister must lay
in latitude 42 degrees 53 minutes North.* (* This is correct.) Wind
Westerly, North-West, Calm.

Tuesday, 6th. Moderate breezes and Clear weather these 24 Hours. A.M.
found the Variation by the Mean of 5 Azimuth to be 21 degrees 40 minutes
West, 3 Degrees more than what it was found Yesterday, which I cannot
account for,* (* Cook, as all other navigators of his time, was unaware
of the deviation of the compass caused by the iron of the ship.) as both
Observations appeared to me to be equally well made. At 10.28 had an
Observation of the sun and moon, which gave the Longitude 9 degrees 40
minutes West from Greenwich. By this Observation Cape Finister must lay
in 8 degrees 52 minutes, and by that made yesterday in 8 degrees 40
