Captain Cook, reduced from his observations at Botany Bay, 1770: 151 11
32.
Captain Hunter, 1788: 151 19 43.
Lieutenant Dawes 1788: 151 18 50.

Ditto 1802: 151 11 49.
Captain De Freycinet, 1802: 151 8 32.
M. D'Espinosa by an eclipse of sun and occultation of Jupiter 1st and 2nd
Satellites, 1793: 151 12 45.
Governor Bligh, 1806, eclipse of sun: 151 17 49.
Captain P.P. King, 1817, eclipse of sun, calculated by Mr. Rumker: 151 17
29.
Sir Thomas Brisbane, 1822 (the mean of six eclipses places his
observatory in 151 degrees 15 minutes 20 seconds): 151 15 32.
Mr. Rumker, eclipse of sun at Parramatta, reduced to Fort Macquarie: 151
17 30.

Mean Longitude of Fort Macquarie 151 15 26.

PERCY ISLAND (Number 2). The longitude of the south-west end of this
island is by Captain Flinders' observation in 150 degrees 13 minutes
East.

ENDEAVOUR RIVER. The observatory, which was placed within a few yards of
the shore on the south side of the entrance (the summit of the highest
bush near the extremity of the opposite sandy beach, bearing by compass
West 3 degrees 40 minutes South) was found to be situated in latitude 15
degrees 27 minutes 4 seconds, and longitude 145 degrees 10 minutes 49
seconds. (See note, Appendix A.)

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 voyag
