[Footnote 7: The very intelligent officer mentioned in the preceding note, seems to have been very materially benefited by the observations of Captain Cook, in navigating this quarter, and does not hesitate to avow his obligations. An instance of this is recorded in our account of Byron’s voyage, vol. 12, p. 74, which refers to a passage in the next section as to the currents losing their force at ten or twelve leagues from land.—E.]
SECTION IV.
Observations, geographical and nautical, with an Account of the Islands near Staten Land, and the Animals found in them.[8]
[Footnote 8: It has been thought advisable to retain this section verbatim, although the references it makes to Captain Cook’s chart can scarcely be understood without that accompaniment, and several observations of another sort which it contains, are given elsewhere. In justice to the memory of Cook, it was resolved to preserve the whole of his relation, at the risk of a very trivial repetition, which the reader, it is believed, will be little disposed to resent.—E.]
The chart will very accurately shew the direction, extent, and position of the coast, along which I have sailed, either in this or my former voyage. The latitudes have been determined by the sun’s meridian altitude, which we were so fortunate as to obtain every day, except the one we sailed from Christmas Sound, which was of no consequence, as its latitude was known before. The longitudes have been settled by lunar observations, as is already mentioned. I have taken 67 deg. 46’ for the longitude of Cape Horn. From this meridian the longitudes of all the other parts are deduced by the watch, by which the extent of the whole mast be determined to a few miles; and whatever errors there may be in longitude, must be general. But I think it highly probable that the longitude is determined to within a quarter of a degree. Thus the extent of Terra del Fuego from east to west, and consequently that of the straits of Magalhaens, will be found less than most navigators have made it.
