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.
