There are certainly no islands in the latitude given except Pitcairn.) If Quiros was in the Latitude of 26 degrees and Longitude 146 degrees West, then I am certain that no part of the Southern Continent can no where extend so far to the Northward as the above mentioned Latitude.

But the Voyage which seems to thrust it farthest back in the Longitude I am speaking of, viz., between 130 and 150 degrees West, is that of Admiral Roggeween, a Dutchman, made in 1722, who, after leaving Juan Fernandes, went in search of Davis's Island; but not finding it, he ran 12 degrees more to the West, and in the Latitude of 28 1/2 degrees discover'd Easter Island.
Dalrymple and some others have laid it down in 27 degrees South and 106 degrees 30 minutes West, and supposes it to be the same as Davis's Isle, which I think cannot be from the Circumstance of the Voyage; on the other hand Mr.Pingre, in his Treatise concerning the Transit of Venus, gives an extract of Roggeween's Voyage and a map of the South Seas, wherein he places Easter Island in the Latitude of 28 1/2 degrees South, and in the Longitude of 123 degrees West* (* Easter Island is in longitude 110 degrees West, and is considered identical with Davis' Island.) his reason for so doing may be seen at large in the said Treatise.

He likewise lays down Roggeween's rout through those South Seas very different from any other Author I have seen; for after leaving Easter Island he makes him to steer South-West to the height of 34 degrees South, and afterwards West-North-West.

If Roggeween really took this rout, then it is not probable that there is any Main land to the Northward of 35 degrees South.

However, Mr.Dalrymple and some Geographers have laid down Roggeween's track very different from Mr.Pingre.From Easter Isle they have laid down his Track to the North-West, and afterwards very little different from that of La Maire; and this I think is not probable, that a man who, at his own request, was sent to discover the Southern Continent should take the same rout thro' these Seas as others had done before who had the same thing in View; by so doing he must be Morally certain of not finding what he was in search of, and of course must fail as they had done.
