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.
