Wednesday, 2nd. A Steady breeze and fine pleasant weather. This Afternoon, by the mean of Several Azimuths and the Amplitude, found the Variation to be 0 degrees 34 minutes East, from which it appears that about the aforegoing Noon we have Crossed the Line of no Variation in the Latitude of 10 degrees 38 minutes South, and, according to the following Observations, in 32 degrees 0 minutes West longitude from Greenwich. At 5 hours 5 minutes 0 seconds Apparent time a.m. the longitude of the Ship and the Observation of the moon and the star Aldebaran was found to be 32 degrees 0 minutes 45 seconds; at 8 hours 17 minutes 0 seconds, per sun and moon, 32 degrees 25 minutes 0 seconds; and at 9 hours 0 minutes 16 seconds, 32 degrees 19 minutes 0 seconds. The mean of the three is 32 degrees 14 minutes 55 seconds. And again at 7 hours 12 minutes 52 seconds, per sun and moon, 32 degrees 10 minutes 4 seconds; and at 7 hours 19 minutes 42 seconds, per sun and moon, 32 degrees 15 minutes 20 seconds. The mean of these two is 32 degrees 12 minutes 42 seconds, and the mean of the whole is 32 degrees 13 minutes 43 seconds West from Greenwich, which is less by a whole Degree than that by account, which is a Considerable Error to be made in 5 Days in these low Latitudes. One would think from this that we must have had a Current setting to the Eastward, which is not likely that it should set against the settled trade wind. The 3 first of these Observations were made by Mr. Green, and the 2 last by myself. Wind East-South-East, South; course South by West; distance 132 miles; latitude 12 degrees 48 minutes South, longitude 32 degrees 20 minutes West per Observation.
