Captain Cook and Mr. Wales placed Otaheite (Point Venus) in 149° 35' — 

 but subsequently Mr. Wales considered 149° 30' more correct. 



In Cook's first voyage the longitude of Otaheite was made 149° 32' 30"; in 

 the second, Mr. Wales made it 149° 34' 50''; and in the third voyage. Cook and 

 his officers made it 149° 37' 32" w. (at Point Venus). 



I was informed that M. Duperrey, in the Coquille, made the longitude of the 

 Bay of Islands 174° 01' 00" e. Our observations were made at the same point, 

 and, if such is the case, his result agrees with that of the Beagle, taken west- 

 ward from Greenwich.
