GOULBURN ISLANDS. The observations were taken
upon Bottle Rock, the largest of two rocky islets
at the north end of South-west Bay; but the results
were so doubtful and unsatisfactory, that the longitude
determined by the chronometers was preferred.
The following are the observations that were taken
to fix its situation, namely:
Latitude by fourteen meridional altitudes of the sun
l. l. on the sea-horizon, taken in various parts of
the bay, and reduced by survey to Bottle Rock 11 37
24.
The difference of longitude between Bottle Rock and
Cassini Island by chronometers, taken in:
1819: 7 40 47. 1820: 7 40 00. 1821:
7 38 28.
Mean difference between Cassini Island and Bottle
Rock: 7 39 45.
Longitude of Cassini Island from Careening Bay, by
survey: 125 38 46.
Longitude of Bottle Rock, by chronometer, from Cassini
Island: 133 18 31.
The mean of the results of the lunar distances that
were taken during the years 1818 and 1819, gave for
the longitude of the rock 133 degrees 31 minutes 58
seconds East. On our last voyage the mean of the
Bathurst’s and Dick’s watches made it
133 degrees 19 minutes 40 seconds, which was finally
adapted, since it accorded better with the chronometrical
difference between its meridian and that of Cassini
Island. I have never been able to account for
this extraordinary disagreement between the results
of the lunar distances and the chronometers, since
the former were taken with the sun on both sides of
the moon, and seemed to be very good.
CAREENING BAY. This place was fixed by a series
of observations, in latitude 15 degrees 6 minutes
18 seconds South, and 125 degrees 0 minutes 46 seconds
East. (See Appendix A. in a note.)
KING GEORGE THE THIRD’S SOUND. The longitude
of this place was adapted from the observations and
survey of Captain Flinders, as follows; namely:
The tent on the east shore of the entrance of Oyster
Harbour. Latitude 35 degrees 0 minutes 17 seconds,
and longitude 117 degrees 56 minutes 22 seconds.
The sandy beach under the low part of the land of
Bald Head (the first sandy bay round the head) is
in latitude 35 degrees 6 minutes, and longitude 117
degrees 58 minutes 6 seconds.
COEPANG, in the Island of Timor. The situation
of the flag-staff of FORT CONCORDIA, where our chronometers
were rated, is in latitude 10 degrees 9 minutes 6
seconds, and longitude 123 degrees 35 minutes 46 seconds,
according to the observations of Captain Flinders.
