Rh Wind E. to E.S.E.; course, S. ½ W.; distance 114 m.; lat. 9° 1′ S., long. 33° 16′ W.

Tuesday, November 1st—Moderate breezes, for the most part Cloudy. Variation by the mean of Several Azimuths 0° 58′ W. in the Evening, and in the Morning found it to be 0° 18′ W. Wind E.S.E.; course S. ¾ W.; distance 98 m.; lat. 10° 38′ S.

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° 34′ E., from which it appears that about the aforegoing Noon we have Crossed the Line of no Variation in the Lat. of 10° 38′ S., and, according to the following Observations, in 32° 0′ W. long. from Greenwich. At 5ʰ 5′ 0″ Apparent time a.m. the long. of the Ship and the Observation of the moon and the star Aldebaran was found to be 32° 0′ 45″; at 8ʰ 17′ 0″, per sun and moon, 32° 25′ 0″; and at 9ʰ 0′ 16″, 32° 19′ 0. The mean of the three is 32° 14′ 55″. And again at 7ʰ 12′ 52″, per sun and moon, 32° 10′ 4″; and at 7ʰ 19′ 42″, per sun and moon, 32° 15′ 20″. The mean of these two is 32° 12′ 42″, and the mean of the whole is 32° 13′ 43″ W. 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 E.S.E., S.; course S. by W.; distance 132 m.; lat. 12° 48′ S, long. 32° 20′ W. per Observation.

Thursday, 3rd—A Fresh Trade wind and fair weather. Variation per Azimuth this Evening 0° 47′ E., and at a little past 9 a.m. long. in per sun and moon 33° 0′ W. of Greenwich. Wind E. by S.E.; course S. 15° W.; distance 128 m.; lat. 14° 51′ S., long. 33° 7′ W.

Friday, 4th—A Steady Gale and fair weather. P.M. Variation per Azimuth 1° 29′ W., ditto 1° 28′ W., and by the Amplitude 1° 12′ W.; mean 1° 23′ W., by which it appears that we have again Crossed the Line of no Variation. At ½-past 9 a.m. the long. of the Ship, per Observation of the sun and moon, 33° 26′ 30″. Wind E. by S.; course S. 19° 30′ W.; distance 125 m.; lat. 16° 49′ S., long. 33° 37° W.

Saturday, 5th.—Fine pleasant weather. Variation per Azimuth this morning 3° 21′ E., which makes me Doubtful of the Variation found yesterday, tho' at the time I had not the least room to doubt of the Accuracy of the Observations. Long. per Observation 34° 43′ 30″ W. Wind E. to N.E.; course S. 30° 35′ W.; distance 109 m.; lat. 18° 22′ S., long. 34° 50′ W.
