A crystalline rock, consisting of greenish-grey hornblende, with a very small proportion of felspar (Hornblende rock ?).
Fragment, apparently from a columnar mass, of a stone intermediate between clink-stone and compact felspar.
Such of the English Company's Islands as were examined by Captain Flinders, are stated by him to consist, in the upper part, of a grit, or sandstone, of a close texture; the lower part being argillaceous, and stratified, and separating into pieces of a reddish colour, resembling flat tiles.

The strata-dip to the west, at an angle of about 15 degrees.
South-west bay of GOULBURN'S SOUTH ISLAND, two hundred and fifty miles west of the Gulf of Carpentaria (Narrative 1).

Coarse-grained reddish quartzose conglomerate and sandstone; resembling the older sandstones of England and Wales, and especially the mill-stone grit beneath the coal formation.

Fine greyish-white pipe-clay; of which about thirty feet in thickness were visible, apparently above the sandstone last mentioned.
Coarse-grained, ferruginous sandstone, containing fragments of quartz, from above the pipe-clay.

The appearance of the cliff from which these specimens were taken, is represented in the view of the bay on the south of Goulburn Island (volume 1); and a distant head in the view consists of the same materials.
SIMMS ISLAND, on the west of Goulburn's south Island (Narrative 1) is composed of a reddish conglomerate, nearly identical with some of the specimens above-mentioned.
The western side of LETHBRIDGE BAY, on the north of MELVILLE ISLAND, consists of a range of cliffs like those at Goulburn's Island; the upper part being red, the lower white and composed of pipe-clay.
