ROSILY, and THEVENARD ISLES are low and sandy; they were seen by us at a considerable distance.
BARROW'S ISLAND, of about forty miles in circumference, is of moderate height and level aspect, but of very sterile and barren appearance.

A considerable reef extends towards the main from its south-east side, where there is also a small islet: on the north-east side are three islets; the two outermost of which are low and rocky.

The west coast of Barrow's Island was seen by the French, who thought it was part of the main; they named its north-west end, CAPE DUPUY, and its south end, CAPE POIVRE.

At ten miles South 25 degrees West from the last cape, the French charts have assigned a position to a reef: and four miles North 10 degrees East from Cape Dupuy is another.

Neither were noticed by us, since we did not approach this part sufficiently near to see them if they do exist; of which, from the account of the French, there can be but little doubt.
LOWENDAL ISLAND and TRIMOUILLE ISLAND were seen by us, but not any vestige of HERMITE ISLAND, which the French have placed in their chart.
From M.de Freycinet's account, the two latter islands were seen at different times; and since Trimouille Island has a reef extending for five miles from its north-western extremity, as Hermite Island is described to have, there seems to be good reason to suppose that there is but one; had there been two, we should have seen it on passing this part in 1822.* (*Footnote.
