APPENDIX. 
[C. 
south-west, as far as Cape Cuvier, the general height of the 
coast is from four to five hundred feet ; nor are any moun- 
tains visible over the coast range. 
Several portions of the shore between Shark’s Bay and 
Cape Naturaliste have been described in the account of 
Commodore Baudin’s Expedition; but some parts still remain 
to be surveyed. From the specimens collected by Captain 
King and the French descriptions, it appears that the islands 
on the west of Shark’s Bay abound in a concretional calcareous 
rock of very recent formation, similar to what is found on the 
shore in several other parts of New Holland, especially in the 
neighbourhood of King George’s Sound ; — and which is abun- 
dant also on the coast of the West Indian Islands, and of 
the Mediterranean. Captain King’s specirhens of this pro- 
duction are from Dirk Hartog’s and Rottnest Islands ; and 
M. Peron states that the upper parts of Bernier and Dorre 
Islands are composed of a rock of the same nature. This 
part of the coast is covered in various places with ex- 
tensive dunes of sand; but the nature of the^base, on which 
both these and the calcareous formation repose, has not 
been ascertained. 
The general direction of the rocky shore, from North-west 
Cape to Dirk Hartog’s Island, is from the east of north to 
the west of south. On the south of the latter place the land 
turns towards the east. High, rocky and reddish cliffs have 
been seen indistinctly about latitude 27° ; and a coast of 
the same aspect has been surveyed, from Red Point, about 
latitude 28°, for more than eighty miles to the south-west. 
The hills called Moresby’s flat-topped Range, of which Mount 
Fairfax, latitude 28° 45', is the highest point, occupy a space 
of more than fifty miles from north to south. 
Rottnest Island and its vicinity, latitude 32°, contains in
