K. George's Sound.-] TERRA AUSTRALIS. 
The Latitude of the tents in Princess-Royal 1802 
Harbour, from three meridian zenith dis- January 
tances of the sun, observed with Ramsden's 
universal theodolite, was - - 35 2 5 south. 
Longitude from thirty-one sets of distances of 
the sun east and west of the moon, of which 
the particulars are given in Table I. of the 
Appendix to this volume, - 117 53 10 east. 
These being reduced by the survey to Bald Head, at the entrance 
of the sound, will place it in 
0 in 
Latitude - 35 6 15 south. 
Longitude - 118 o 45 east.* 
The mean rates of the time keepers, deduced from equal alti- 
tudes taken on and between Dec. 15 and Jan. 1, and their errors 
from mean time at Greenwich, at noon there on the last day of ob- 
servation, were as under : ., 
Earnshaw's No. 543, slow o 21 46,69 and losing 6,46 per day. 
No. 520, o 51 2,81 16,72 
Arnold's No. 176, 1 0 45,46 9,26 
No. 82 went too irregularly to be worth taking. 
The longitude of the tents given by the time keepers on the 
first day of observation, with the Cape rates, was as follows : 
Earnshaw's No. 543, 118 0 14' 49" east. 
520, 117 59 22 
Arnold's 176, 118 1 14 
The two first, which generally throughout the voyage shewed them- 
selves to be the best time keepers, were on a mean 13' 56" to the 
east of the lunar observations ; but by using rates accelerating in 
* The situation of Bald Head, in captain Vancouver's chart, is 35° 6' 40" south, and 
118° 16' 30" east from lunar observations which were not corrected for the errors of the 
astronomical tables. The situation assigned to Bald Head in the voyage of the French 
admiral D'Entrecasteaux, is 35° 10' south, and 118° 2' 40" east; but since the admiral 
passed it at six in the evening, and in blowing weather, an error of a few minutes may 
have entered into both latitude and longitude.
