or nests,
but unaccompanied by any portion of the adjacent rock. The structure in
one of these specimens approaches to the amygdaloidal. A compact greenish
stone, with disseminated crystalline spots of epidote, and of quartz, and
apparently consisting of an intimate mixture of those minerals, is also
among the specimens from Port Warrender.

All these specimens are from detached water-worn masses at the foot of
Crystal Head, on the south-west of the port. The summit of the head is
flat and tabular, and the rocks in the vicinity are described by Captain
King as consisting of siliceous sandstone. Chalcedony, apparently from
amygdaloid of the trap formation, was also found at Port Warrender.

The epidote of this place is in general of a pale-greenish colour, but is
mixed with, and sometimes appears to pass into, spots of a rich
purplish-brown. The specimens resemble generally the epidote of Dauphiny
and Siberia; but Mr. Levy, who has been so good as to examine them,
informs me that the crystals exhibit some modifications not described
either by Hauy, or by Mr. Haidinger in his paper on this mineral, and
which are probably peculiar to this locality.

WATER ISLAND, on the west side of CAPE VOLTAIRE, at the south-west
entrance of Port Warrender, is described (volume 1) as consisting of
quartzose sandstone; as is also KATER ISLAND, in Montagu Sound. And the
same rock appears to occur throughout the islands on this part of the
coast. (Narrative 1.)

MONTAGU SOUND, about five-and-twenty miles south-west of ADMIRALTY GULF
(Narrative 1). Greyish granular quartz; like that of the Lickey Hill, in
Worcestershire. Fine-grained quartzose sandstone, of a purplish hue,
resembling a rock on the banks of the Severn, near Bridgenorth. Grey and
reddish sandstone; apparently composed of the debris of granite, and very
nearly resembling that of Simms Island above-mentioned.

HUNTER'S RIVER, falling into YORK SOUND, on the north-east side. Somewhat
coarse reddish-white sandstone; like that of the coal formation, and some
varieties of millstone grit. Fine-grained, reddish-grey quartzose
sandstone, having the appearance of stratification, and resembling the
rocks of Cambridge Gulf.

ROE'S RIVER, at the eastern termination of York Sound (Narrative 1) runs
between precipitous banks of sandstone, in nearly horizontal strata,
which rise to the height of three hundred feet.

CAREENING BAY, between York Sound and Prince Regent's River (Narrativ
