[C. 
from Cape Howe, about lat. 37°, to Cape Byron, lat. 29°, or 
even to Sandy Cape, lat 25°; and of the western coast, from 
the south of the islands which enclose Shark’s Bay, lat. 26°, 
to North-west Cape, about lat. 22°. — From Cape Hamelin, 
lat. 34° 12', to Cape Naturaliste, lat. 33° 26', the coast runs 
nearly on the meridian. The two great fissures of the south 
coast, Spencer’s, and St. Vincent’s Gulfs, as well as the 
great northern chasm of the Gulf of Carpentaria, have a 
corresponding direction ; and Captain Flinders (Chart 4,) 
represents a high ridge of rocky and barren mountains, on 
the east of Spencer’s Gulf, as continued, nearly from north to 
south, through a space of more than one hundred geogra- 
phical miles, between latitude 32° 7' and 34°. — Mount 
Brown, one of the summits of this ridge, about lat. 32° 30', 
being visible at the distance of twenty leagues. 
The tendency of all this evidence is somewhat in favour 
of a general parallelism in the range of the strata, — and per- 
haps of the existence of primary ranges of mountains on the 
-east of Australia in general, from the coast about Cape Wey- 
mouth* to the shore between Spencer’s Gulf and Cape Howe. 
But it must not be forgotten, that the distance between these 
shores is more than a thousand miles in a direct line; — about 
as far as from the west coast of Ireland to the Adriatic, or 
* The possible correspondence of the great Australian Bight, 
the coast of which in general is of no great elevation,, with the 
deeply-indented Gulf of Carpentaria, — tending, as it were, to a 
division of this great island into two, accords with this hypothesis 
of mountain ranges : but the distance between these recesses, over 
the land at the nearest points, is not less than a thousand English 
miles. — The granite, on the south coast, at Investigator’s Islands, 
— and westward, at Middle Island, Cape Le Grand, King George’s 
Sound, and Cape Naturaliste, is very wide of the line above- 
mentioned, and nothing is yet known of its relations.
