TERRA AUSTRALIS.

The latitude of our anchorage at the northern 
entrance, from four meridian altitudes of 
the sun, is - _ 
2 3 ° 44 ' 16" south. 
1802. 
August. 
Six sets of distances of the sun west of the 
moon, taken by lieutenant Flinders, would 
make the longitude 151 0 sT 22" east; the 
two time keepers gave 151 0 so' 10"; and 
fifty sets of distances, reduced from Broad 
Sound by the survey, which I consider to 
be the best authority, place the anchor- 
age in 151 20 eas ^ 
These being reduced by the survey to the southern entrance, place 
Gatcombe Head in latitude 23 0 52I' S. 
longitude 151 24 E. 
No variations were observed at the anchorage ; 
but two amplitudes off Gatcombe Head 
gave 11 0 n', and azimuths with three 
compasses, io° 50' east, the ship’s head 
being W. S. W. and W. N. W. These 
being reduced to the meridian, will give 
the true variation to be - 8° 40' east. 
This is an increase of near 2 0 from Bustard Bay ; and seems attribut- 
able to the attraction of the granitic land which lay to the westward, 
and drew the south end of the needle that way. 
The rise of tide at the place where I slept near the head of the 
port, was no more than four feet ; but upon the rocky islet in the 
northern entrance, there were marks of its having risen the double 
of that quantity. The time of high water was not well ascertained, 
but it will be between eight and nine hours after the moon’s passage 
over and under the meridian. 
On getting under way at daylight of the 9th, to prosecute the Monday 9. 
examination of the coast, the anchor came up with an arm broken 
off, in consequence of a flaw extending two-thirds through the iron.
