Saturday, 29th. Fresh Breezes and pleasant weather. Variation of the Compass 2 degrees 25 minutes West. Wind East-South-East; course South by West; distance 101 miles; latitude 5 degrees 25 minutes South, longitude 32 degrees 48" West. Sunday, 30th. A Steady breeze, and for the most part close cloudy weather. Variation by several Azimuths 1 degree 31 minutes West. At noon the observed latitude 7 miles southward of account. Wind East-South-East; course South 3/4 West; distance 107 miles; latitude 7 degrees 8 minutes South, longitude 33 degrees 4 minutes West. Monday, 31st. A Fresh breeze and Clear weather. Variation 0 degrees 15 minutes West. Observed Latitude again to the Southward of the Log. Wind East to East-South-East; course, South 1/2 West; distance 114 miles; latitude 9 degrees 1 minute South, longitude 33 degrees 16 minutes West. [November 1768. Between Equator and Rio.] Tuesday, November 1st. Moderate breezes, for the most part Cloudy. Variation by the mean of Several Azimuths 0 degrees 58 minutes West in the Evening, and in the Morning found it to be 0 degrees 18 minutes West. Wind East-South-East; course South 3/4 West; distance 98 miles; latitude 10 degrees 38 minutes South. 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.
