July 26.
On our voyage from Torres Strait to the western head of the Gulf of Carpentaria, which is Cape Arnhem, no incident occurred of sufficient interest to be worth recording; but no sooner had we passed Torres Strait than a very sensible difference was perceived in the temperature: the thermometer was observed to range between 75 and 83 degrees, which was about 3 degrees higher than it did on the south side of the Strait; this change produced a drier air and finer weather and soon restored our invalids to perfect health.
July 27.
Soon after daylight on the 27th Wessel's Islands, which had been seen the preceding evening, were descried bearing from West-North-West to South-West by West; and shortly afterwards lower land was observed more to the northward, towards the extremity of which we steered.
The eastern side of Wessel's Islands presents a level aspect; only a few shrubby trees appear at intervals to break the uniformity of its gently undulating outline.

The point, which is named Cape Wessel, is the extremity of the northernmost island of the group and is separated from that to the southward of it by a narrow and apparently a rocky strait.
On approaching within a mile and a half of the Cape we passed through a strong rippling tide without having soundings with fifteen fathoms.

Six natives were seen sitting on the verge of the cliffs that overhang the Cape, watching us as we passed; and farther on two more were observed walking on the beach.

On the west side of the Cape is a small sandy bay in which there appeared to be good anchorage.
In passing this bay we fell into another strong tide race, in which the sea curled and foamed about us as if we were in the midst of breakers; but, as before, no bottom was found with fifteen fathoms.
