steered W. by S. by compass, the soundings increasing gradually from 7 fathoms to 13 at noon, when our latitude was 10° 38′ and longitude 141° 17′. No reefs or other dangers had been seen to the west of Booby Isle; nor were any met with in steering across the Gulph of Carpentaria towards Cape Wilberforce, though many birds, principally boobies, were seen every day. We ran in the night, with the precaution of heaving to every four hours, to sound; the depth was from 30 to 36 fathoms on a muddy bottom, nearly all across the Gulph.

On the 28th at two in the morning, Cape Wilberforce being seen directly a-head, we hove to in 18 fathoms till daylight; the south-east extreme of the cape then bore S. 54° W., and the largest of Bromby's Isles was two miles distant to the northward. After making some short tacks, we passed through between the two outer isles, with soundings from 6 to 11 fathoms; and at ten o'clock, when clear of the passage, the bearings of the nearest lands were as under: The longitude of our situation according to the positions laid down in the Investigator, would be 136° 41′ 10″, and the time keeper now gave 136° 42′ 12″. It was principally for the sake of comparing the two longitudes, that I made the land near Cape Wilberforce.

We steered northward for the two islets, and at noon, when the latitude from an observation to the south was 11° 43′, but from bearings 11° 42′, they were distant three quarters of a mile to the W. by S.; these islets had been set from the south-east head of Cotton's Island at N. 42° 35′ to 45° 5′ E., and that head was now seen bearing S. 45¼° W. At one o'clock the Wessel's Islands came in sight, and I hauled more up, wishing to ascertain their extent to the northward; but the wind being at E.N.E., we could not pass to
