SURVEY OF THE INTERTROPICAL 
1822 . The south-east cape of Bruny Island, Tasman’s 
Oct. 6 . Head, is also placed too much to the southward 
in Captain Flinders’s chart, as well as in that 
of Baudin. From the Mermaid it was set in a line 
with the south-east cape, on the bearing of N. 
56° E. (the vessel’s head being to the eastward) ; 
and on this occasion (the brig’s head being to 
the westward) it bore, when in the same line, 
N. 53° E. The variation in the latter case was 
9° E., but in the former no more than 6° was 
allowed, and Captain Flinders found even 4° 
sufficient. 
I passed outside the Mewstone, and took its 
bearing as it came on with the points of the 
land between the south-west and the south-east 
capes, by which I satisfied myself beyond a 
doubt of the correctness of my observations, and 
of the error into which Captain Flinders had 
fallen, and which must either be attributed to 
the imperfection of his instrument, or to his 
reading off* the altitude 10' in error ; and as 
there is just that difference between it and the 
position assigned by Captain Furneaux, which 
is also confirmed by my observation, the proba- 
bility is in favour of the last conjecture. 
After leaving the coast of Van Diemen’s Land 
we had much damp, unwholesome weather, and
