udge from the appearance of those who had resided any length of time
at Coepang, the climate is not good; for even in comparison with us, who
had suffered considerably, they were sickly looking people. Yet they did
not themselves consider the colony as unhealthy, probably from making
their comparison with Batavia; but they spoke of Diely, the Portuguese
settlement, as very bad in this respect. Captain Baudin had lost twelve
men from dysentery, during his stay at Coepang, and I found a monument
which he had erected to his principal gardener; but it was even then
beginning to decay.

The _latitude_ of our anchorage, three-fifths of a mile to the north of
Fort Concordia, was 10 deg. 8' 2" from seven meridian altitudes of the sun;
but these being all taken to the north, I consider it to be more
correctly, 10 deg. 81/2' S.

_Longitude_ of the anchorage and fort, from fifty four sets of lunar
distances, of which the particulars are given in Table VII. of the
Appendix No. I., 123 deg. 35' 46" E.

Lieutenant Flinders took altitudes from the sea horizon, between April 1
p.m. and 8 a.m., for the rates of the time keepers; the mean of which,
with the errors from mean Greenwich time at noon there on the last day of
observation, were as under:

Earnshaw's No. 543, slow 2h 57' 14.56", and losing 16.73", per day,
Earnshaw's No. 520, fast 1h 57' 19.28", and losing 33.99", per day;

the rate of No. 543 differing only 0.2" from that with which we had left
Caledon Bay. The longitude given by this time keeper on April 1, p.m.,
with the Caledon rate, was 123 deg. 39' 8.4" east, or 3' 22" more than the
lunars; and when the Caledon rate is accelerated, the difference is only
2' 31/2" east. This quantity, if the longitudes of Caledon and Coepang Bays
be correct, is the sum of the irregularities of No. 543, during the
fifty-one days between one station and the other. The time keeper No. 520
had been let down on the passage, and its rate being now more than 3"
greater than at Caledon Bay, its longitude was not attended to at this
time.

In laying down the coasts and islands of Arnhem's Land, the bearings and
observed latitudes were used, with very little reference to the time
keepers; but No. 543, when corrected, did not differ so much from the
survey as 1' in twenty-five days. The rest of the track, from Wessel's
Islands to Coepang, is laid down by this time keeper with the accelerated
rate, and the application of a proportional part of
