On the 8th, we were in the latitude of 8° 57' S.; which is a little to the southward of Cape St Augustine, on the coast of Brazil. Our longitude, deduced from a very great number of lunar observations, was 34° 16' W.; and by the watch, 34° 47'. The former is 1° 43', and the latter 2° 14' more westerly than the island of Fernando de Noronha, the situation of which was pretty well determined during my late voyage. Hence I concluded that we could not now be farther from the continent than twenty or thirty leagues at most; and perhaps not much less, as we neither had soundings nor any other signs of land. Dr Halley, however, in his voyage, published by Mr Dalrymple, tells us,[85] that "he made no more than one hundred and two miles, meridian distance, from the island [Fernando de Noronha] to the coast of Brazil;" and seems to think that "currents could not be the whole cause" of his making so little. But I rather think that he was mistaken, and that the currents had hurried him far to the westward of his intended course. This was, in some measure, confirmed by our own observations; for we had found, during three or four days preceding the 8th, that the currents set to the westward; and, during the last twenty-four hours, it had set strong to the northward, as we experienced a difference of twenty-nine miles between our observed latitude and that by dead reckoning. Upon the whole, till some better astronomical observations are made on shore on the eastern coast of Brazil, I shall conclude that its longitude is thirty-five degrees and a half, or thirty-six degrees W., at most.
We proceeded on our voyage, without meeting with any thing of note, till the 6th of October. Being then in the latitude of 35° 15' S., longitude 7° 45' W., we met with light airs and calms by turns, for three days successively. We had, for some days before, seen albatrosses, pintadoes, and other petrels; and here we saw three penguins, which occasioned us to sound; but we found no ground with a line of one hundred and fifty fathoms. We put a boat in the water, and shot a few birds; one of which was a black petrel, about the size of a crow, and, except as to the bill and feet, very like one. It had a few white feathers under the throat; and the under-side of the quill-feathers were of an ash-colour. All the other feathers were jet black, as also the bill and legs.
