m is an extensive coral reef, extending for fifteen miles in North East by North direction, parallel with l, from which it is separated by a channel of from one to two miles wide. At its south-west end, where there is an extensive dry sandy key, and some dry rocks, it is two miles wide: but towards its northern end it tapers away to the breadth of a quarter of a mile. The south trend of its south-west end lies seven miles North 44 degrees West from Pelican Island, and four miles from Island 2 of Claremont Isles. n is another extensive reef, which may possibly be connected with m. At its westernmost end, about four miles North by East 1/2 East from the west end of m., is a dry sand of small extent. It was considered probable that there was a safe passage between the reefs l and m. We steered so far as to see the termination of the latter, upon which the sea was breaking, which afforded a proof of its not being connected with the former, which also the dark colour of the water sufficiently indicated. The Mermaid was nearly lost in attempting to cross the latter reef. (Volume 1.) CLAREMONT ISLES consist of five small islets, numbered from 1 to 5; they are of coral formation, and are covered with small brushwood; they are from six to seven miles apart, excepting 4 and 5, which are separated by a channel only a mile and a half wide: off the east and south-east end of 5, a coral reef extends for a mile and a half to the eastward, having two dry rocks on its north-east end.

Reef o extends in an east and west direction for a mile and a half, and at a mile farther there is another reef, that may be connected to it; o has a dry sand near its western extremity, in latitude 13 degrees 34 minutes, and longitude 143 degrees 38 minutes 45 seconds. Islet 6, in latitude 13 degrees 29 minutes, longitude 143 degrees 38 minutes 26 seconds, is a very small, low, woody islet, with a reef extending for three-quarters of a mile off its north and south ends. A reef lies two miles and one-third North 72 1/2 degrees West from islet 6, and South 59 degrees East from the summit of Cape Sidmouth; this reef is not more than a quarter of a mile in extent, and has a rock in its centre, that is uncovered at half tide; it is a brown looking shoal, and therefore of dangerous approach. Off ROUND HILL there is a sandbank covered by the sea; it lies about two miles from the shore, and about East-North-East from Round Hill summit. q is a small, brown, rocky shoal, that is not visible until close to it; it bears South 60 degrees East, four miles from the extremity of Cape Sidmouth.
