Light grey quartzose sandstone of a fine grain, with a thin coating of brown hematite, was also found in this island: And a breccia, consisting of angular fragments of sandstone, cemented by thin, vein-like, coatings of dark brown hematite, was found there, in loose blocks at the bottom of perpendicular cliffs.

The specimen of this breccia is attached to a plate of granular quartz, and may possibly have been part of a vein.
The shore of INGLIS' ISLAND, the largest of the ENGLISH COMPANY'S RANGE (2.2.2.in the Map) is formed of flat beds, of a slaty argillaceous rock, which breaks into rhomboidal fragments; but the specimen is indistinct.

Ferruginous masses, probably consisting of brown hematite, come also from this island.
ASTELL'S ISLAND, north-east of Inglis' Isle.

Very fine-grained greyish-white quartzose sandstone; identical with that of Mallison's Island, and very closely resembling some of the specimens from Prince Regent's and Hunter's Rivers.
Among the remaining islands of this range, BOSANQUET'S, COTTON'S, and POBASSOO's Isles, were found by Mr.Brown to consist, in a great measure, of sandstone, of the same character with the specimens above-mentioned.
POBASSOO'S ISLAND, a small islet south-east of Astell's Isle.
Fine-grained, somewhat reddish, sandstone.

Another specimen of sandstone is friable, of a light flesh-red colour, and apparently composed of the debris of granite.
