The next morning we were off Cape Croker and at noon were passing Port Essington; the projecting heads of which, at the distance of four or five leagues, have the appearance of being two small islands, for the land at the back and on either side is too low to be seen. Between Port Essington and Cape Van Diemen we steered so as to see several parts of the coast of Melville Island in order to compare their relative meridional distances with those of last year's survey. August 22. The latter projection, which is the western limit of the north coast, came in sight on the evening of the 22nd when its longitude was found to be 130 degrees 19 minutes 33 seconds, which is 1 minute 2 seconds to the westward of last year's observation; the mean therefore may be considered as its true longitude, which is 130 degrees 20 minutes 30 seconds. At sunset we were eleven miles from the Cape, bearing South 67 1/2 degrees West. August 23. And the next morning it was seen in the South-South-East. After rounding it a course was steered down the western side of Bathurst Island. August 26. But it took us until the 26th before we passed Cape Fourcroy. August 27. On the following evening we made the land on the south side of Clarence Strait in the vicinity of Vernon's Islands: this was the last land seen by us on leaving the coast in May, 1818. Between Goulburn Island and this part we had a succession of light baffling winds, with sultry, damp, and hazy weather, which proved very unfavourable for our sick, the number of whom was increasing. Mr. Bedwell was confined to his bed with a serious attack of dysentery, occasioned by exposure to the sun whilst superintending the shore parties at Goulburn Island; and the greater part of the crew were affected with ophthalmia, probably occasioned by the excessive glare and reflection of the sun's rays from the calm glassy surface of the sea. August 28. At daylight on the 28th we found ourselves near the land to the south-west of Vernon's Islands, which also were in sight. To the south was a deep opening trending to the south-east of a river-like appearance; but, as it did not seem to be of sufficient importance to detain us, we passed on to the westward.
