volume 1. See the plate volume 1). Crystalline epidote, and whitish
quartz, apparently from a vein. Purplish-brown epidote, with small nests
or concretions of green epidote and quartz; forming a sort of amygdaloid.
Conglomerate, containing angular fragments of yellowish-grey quartz-rock,
in a base of compact epidote. A nearly uniform greenish compound of
epidote intimately mixed with quartz, also occurs at this place. Flat
lamellar chalcedony. Very fine-grained reddish-grey quartzose sandstone,
with traces of a slaty structure, resembling that of York Sound, and
Cambridge Gulf, was found in the north-east end of this bay; and
fine-grained greenstone, on the summit of the adjacent hills.

Several of these specimens are almost identical with those of Port
Warrender; from which place Careening Bay is distant about sixty miles.

BAT ISLAND (Narrative volume 1) western entrance of Careening Bay. Quartz
from thin veins, with particles of an adhering rock, probably
chlorite-slate. Quartz, containing disseminated hematitic iron-ore and
copper pyrites. Quartz crystals, with chalcedony, from nodules in
amygdaloid. Quartz with specular iron ore. Greenstone, with chalcedony
and copper pyrites. A decomposed stone, probably consisting of wacke. The
specimens of trap-rocks from this place are from a cavern.

GREVILLE ISLAND, near the entrance of Prince Regent's River. Reddish,
coarsely granular, siliceous sandstone; in horizontal strata, intersected
by veins of crystallized quartz.*

(*Footnote. Narrative volume 2.)

HALF-WAY BAY, within Prince Regent's River on the west of the entrance,
near Greville Island. Hornblende rock ? nearly agreeing with that of
Pobassoo's Island, on the north-west of the Gulf of Carpentaria (see
above). Calcedony, apparently from nodules in amygdaloid. Greenish
quartz, approaching to heliotrope. Red, somewhat slaty jasper, mixed with
quartz and chalcedony, and containing specular iron ore.

The specimens from this place much resemble some of those from Sotto i
Sassi, in the Val di Fassa in the Tyrol, which I have seen in the
collection of Mr. Herschel; and which consist of reddish jasper with
chalcedony, and a greenish flinty stone, like heliotrope, the whole
belonging to the trap-formation.

POINT CUNNINGHAM, east of south from Cape Leveque, and about one hundred
and fifty miles south-west of Prince Regent's River. Very compact and
fine-grained reddish granular quartz, with a glistening lustre, an
