■ 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 
W. 3° 40' S.), was found to be situated in latitude 15° 27' 4", 
and longitude 145° 10' 49". (See note, Appendix A. 
p. 279.) 
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 doubt- 
ful and unsatisfactory, that the longitude determined by the 
chronometers was preferred. The following are the obser- 
vations that were taken to fix its situation, viz. : 
Latitude by fourteen meridional altitudes 
of the O 1. 1. on the sea-horizon, taken in 
various parts of the bay, and reduced by o , „ 
survey to Bottle Rock . . . . 1 1 ,37 24 
The difference of longitude between Bottle 
Rock and Cassini Island by chronometers, 
taken in 1819 ..... 
1820 ..... 
1821 ... 
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
