Chain-Island, an island lately discovered by captain Wallis in the South-sea. It seemed to be about five miles long and as much broad, lying in the direction of north-west and south-east. It appeared to be a double range of woody islands joined together by reefs, so as to compose one island of an oval figure, with a lake in the middle. The trees are large; and from the smoke that issued from the woods, it appeared to be inhabited. W. Long. 145° 54'. S. Lat. 17° 23'.
