error, and on this occasion a very considerable 
one was detected. 
When Captain Flinders passed round Van 
Diemen’s Land in the Norfolk, he obtained a 
meridional supplementary altitude of the sun to 
the south, his vessel being under the land, 
•which made the South-west Cape in 43° 29' S. ; 
but finding the next day that his instrument was 
2' 40" in error to the north, he assigned to the 
cape a position of 43° 32'. In the Introduc- 
tion to his voyage ^ he makes some remarks in a 
note upon the positions assigned to it by Captains 
Cook and Furneaux ; the latter officer placed it 
in 43° 39', in which I also found it to be by its 
transient bearing from the South Cape. By a 
series of bearings carried along the coast, its 
position is thirty -three miles W. 3° S. true, from 
the South Cape. 
All parts of the coast in this interval are pro- 
portionally in error as to latitude, but tolera- 
bly well placed in reference to the coast. The 
subjoined are the positions now assigned to the 
following places, mz, :
