Keppel Bay.~\ 
TERRA AUSTRALIS.

The latitude of our anchorage, from the 
mean of three meridian altitudes to the 
north, was - 
2 3° 2 9 / 34" south. 
1802. 
August. 
Longitude from twenty-four sets of dis- 
tances of the sun and moon, the particu- 
lars of which are given in Table I. of Ap- 
pendix No. I. to this volume, i5i°o' 28"; 
but from fifty other sets, reduced by the 
survey from Broad Sound, the better 
longitude of the anchorage is - 150 58 20 east. 
According to the time keepers the longitude would be 150* 57' 4,3"; 
and in an interval of six days, they were found to err no more than 
5" of longitude on the Port-Jackson rates. 
From three compasses on the binnacle, 
lieutenant Flinders observed the variation 
6° 48', when the ship’s head was north, 
and 5 0 47' when it was south-south-east. 
This last being reduced to the meridian, 
the mean of both will be - 64 7 east, 
nearly the same as in Bustard Bay ; but 2* less than was observed 
off Gatcombe Head. At the different stations round Keppel Bay 
whence bearings were taken, the variation differed from ,5° lo' to 
6° 30' east. 
Whilst beating off’ the entrance, I had 7 0 52' 
east variation, from azimuths with the 
surveying compass when the head was 
N. W., and from an amplitude, with the 
head N. by W., 6° 54'; the mean reduced 
to the meridian, will be for the outside 
of the bay - - - 6 16 east. 
Captain Cook had 7 0 24' near the same situation, from amplitudes 
and azimuths observed in 1770, with the Endeavour’s head W.N. W.
