General Remarks, 133 



Brown, they would seem to point out the arrangement of the 

 strata on the northern coasts of New Holland. 



Of the three ranges which attracted Capt. Flinders' s notice, 

 (see the map, fig. 4, in PI. I.*) the first on the south-east, (3,4,5s 

 6,7,) is that which includes the Red Cliffs, Mallison's Island, a 

 part of the coast of Arnhem's Land, from Cape Newbold to 

 Cape Wilberforce, and Bromby's Isles ; and its length, from 

 the main land (3) on the south-west of Mallison's Island, to 

 Bromby's Isles (7) is more than fifty miles, in a direction nearly 

 from south-west to north-east. The English Company's Islands,, 

 (2, 2, 2, 2,) at a distance of about four miles, are of equal ex- 

 tent; and the general trending of them all, Captain Flinders 

 states (p. 233), is nearly N.E. by E., " parallel with the line 

 of the main coast, and with Bromby's Islands." — WesselFs 

 Islands, (1, 1, 1, 1,) the third or most northern chain, at four- 

 teen miles from the second range, stretch out to more than 

 eighty miles from the main land, likewise in the same direction. 



It is also stated by Captain Flinders, that three of the En- 

 glish Company's Islands which were examined, slope down 

 nearly to the water on their west sides; but on the east, and 

 more especially the south-east, they present steep cliffs; and 

 the same conformation, he adds, seemed to prevail in the other 

 islands f . If this structure occurred only in one or two in- 

 stances, it might be considered as accidental ; but as it obtains 

 in so many cases, and is in harmony with the direction of the 

 ranges, it is not improbably of still more extensive occur- 

 rence, and would intimate a general elevation of the strata 

 towards the south-east. 



Now on examining the general map, it will be seen, that 

 the lines of the coast on the main land, west of the Gulf of 

 Carpentaria, between Limmen's Bight and Cape Arnhem, — 

 from the bottom of Castlereagh Bay to Point Dale, — less di- 

 stinctly from Point Pearce, lat. 14° 23', long. 129° 18', to the 

 western extremity of Cobourg Peninsula, — and from Point 

 Coulomb, lat. 17° 20', long. 123° 11', to Cape Londonderry, 

 have nearly the same direction ; — the first line being about one 

 hundred and eighty geographical miles, the second more than
