We found the longitude of Port Royal bay, in this island, as settled by Captain Wallis, who discovered it on the 9th of June, 1767, to be within half a degree of the truth. We found Point Venus, the northern extremity of the island, and the eastern point of the bay, to lie in the longitude of 149°13', this being the mean result of a great number of observations made upon the spot. The island is surrounded by a reef of coral rock, which forms several excellent bays and harbours, some of which have been particularly described, where there is room and depth of water.
