t's chart of Bass Strait, some rocky islets are placed
forty miles east of Sea-Elephant Bay. I did not succeed in finding them,
although the Mermaid sailed close to their position. (See volume 1.)

The PYRAMID, at the east end of Bass Strait, is placed five miles too
much to the northward: its true situation is in latitude 39 degrees 52
minutes 40 seconds, and longitude 147 degrees 11 minutes 30 seconds.

A reef of rocks were seen by Lieutenant John Lamb, R.N., off Cape Albany
Otway. (See Horsburgh volume 2 page 499.)

There appears to be a considerable difference in the positions assigned
to ALBATROSS ISLAND, by the French expedition and Captain Flinders; the
former made the difference between the meridian of Albatross Island, and
that of the rock in Sea-Elephant Bay, 24 minutes 45 seconds; whilst by
the latter it is 32 minutes 30 seconds. But as Captain Flinders only saw
the north end of KING'S ISLAND, the error seems to originate in his
having laid down its eastern side from other authorities, for his
difference of longitude between its north-west point and the centre of
Albatross Island only differs 2 minutes 30 seconds from the French, who
surveyed that island with great care.

Several sunken rocks have been discovered from time to time near the
north end of GREAT ISLAND, so that ships, bound through Bass Strait to
the eastward, should not pass within Craggy Island without using great
caution. The best passage is on the south side of Kent's Group, between
it and the rocky islet (WRIGHT'S ROCK) to the south-east.

In a line between the above rocky islet and Craggy Island, and about two
miles from the former, is a reef with two small rocks upon it. (See
Horsburgh Supp. page 32.)

There are some considerable errors in Captain Flinders' chart of Van
Diemen's Land, with respect to the latitudes of the South-west Cape, the
Mewstone, the South cape, and the land between them. The first is laid
down 8 minutes too much to the North 30 degrees West (true) and the other
places in proportion. The corrected situations are given in the second
volume of this work.
