In the same direction lie Erromango, Tanna, and Annattom. The first is 18 leagues from Sandwich Island, and is twenty-four or twenty-five leagues in circuit. The middle of it lies in the latitude of 18° 54ʹ, longitude 169° 19ʹ E., and it is of a good height, as may be gathered from the distance we were off when we first saw it. Tanna lies six leagues from the south side of Erromango, extending S. E. by S. and N. W. by N. about eight leagues long in that direction, and every where about three or four leagues broad. The Isle of Immer lies in the direction of N. by E. 1/2 E., four leagues from Port Resolution in Tanna; and the island of Erronan or Footoona east, in the same direction, distant eleven leagues. This, which is the most eastern island of all the Hebrides, did not appear to be above five leagues in circuit, but of a considerable height, and flat at top. On the N. E. side is a little peak, seemingly disjoined from the isle, but we thought it was connected by low land. Annattom, which is the southernmost island, is situated in the latitude of 20° 3ʹ, longitude 170° 4ʹ, and S. 30° East, eleven or twelve leagues from Port Resolution. It is of a good height, with an hilly surface; and more I must not say of it. Here follows the lunar observations by Mr. Wales, for ascertaining the longitude of these islands, reduced by the watch to Port Sandwich in Mallicollo, and Port Resolution in Tanna. {Mean of 10 sets of observ. before 167° 56ʹ 33ʺ 3/4 } E.
