254 ISLAND OF MAURURA. 
Englishman Edwards, who alone are known to 
have since touched on these islands; the former 
visited only the more northern islands; and 
the latter communicated no particulars of his 
voyage to the public. I therefore considered 
it worth the trouble to complete the survey, by 
examining those which lay to the south of La 
Pérouse’s track. 
I at first steered past the Society Islands, 
lying to leeward from Tahaiti, in order to rec- 
tify their longitude; and afterwards carefully 
endeavoured to avoid the course taken, to my 
knowledge, by any former navigator. 
On the 25th of March we saw, to the north, 
the island of Guagein, and to the north-west 
that of Ulietea. When the western point of the 
latter lay due north from us, I found its longi- 
tude, according to our chronometers, 151°26' 30’, 
which is nearly the same as on the maps. 
The island of Maurura, on the contrary, is 
very inaccurately laid down ; we found the longi- 
tude of the middle of this island, as we sailed 
past its southern coast, to be 152° 10’ 40”. In 
the evening we had already cleared the Society 
Islands, and were pursuing a westward course..
