(as understood by him), from the southern point of Tasmania 
to the agen of 28°, in longitude 152°; but not further west- 
d than 146° on the parallel of Mount Alexander. It i is, 
however, doubtful whether the ranges between this furthest 
western point and Wilson’s Promontory, where he considers 
the Chain to be cut off by the sea, is anything more than a 
spur in that direction. 
ut the extent of the Cordillera westerly, to its termination 
on the border of South Australia is so well defined, that there 
can be no question that the 8. W. and W. extension has as 
true a character as any part of the Northern prolongation. 
This may be geologically deduced from researches of the Geo- 
logical Survey of Victoria. That province is limited, at its 
eastern corner, by a line joining Cape Howe and the head of 
the Murray, so that the boundary crosses very near the highest 
point of all Australia, which Strzelecki made 6,500 feet — 
the sea, but which subsequent observations have shown to 
7,175 feet, This correction rests on observations made by Lyne 
in 1852, and a re-discussion of them, in comparison with results 
obtained by Professor Neumayer in "1862. On 8th May, 1852, 
I made the highest point of Kosciusco, 4,077 feet above my 
then base, at 3,098 feet above the sea, which therefore came out 
7,175 feet; and in February, 1863, Professor Neumayer wrote 
me word that he made the highest peak in November, 1862, 
7,175 feet. This makes Kosciusco’s summit above the crossing 
place of the Indi or Hume river, at Groggan’s, 5,42 +; 
The 144th meridian to the northward limits very nearly all 
the high land of the East Coast to Cape Melville, whilst ie 
142nd meridian limits to the westward the basin of the Dar- 
ling, including part of the drainage along the Thomson and 
Barcoo from the head of the oe bad where it passes into 
South Australia, on the 141st meri 
us, all this enormous quislipe or western New South 
Wales and southwestern Queensland is, as it were, bounded 
by ranges of high geological a ee the Grey and Barrier 
groups being of undoubted similar age to the mass of the East- 
ern Cordillera. 
It has long been known that the strike of the older sedi- 
mentary rocks all through the Cordillera, in Victoria, as well as 
in New South Wales, it is generally meridional; so that in the 
ormer province the beds strike across the Cordillera, whilst i in 
the latter they form various angles s from parallelism with it to 
a transverse direction, as the Chain doubles and winds rregu- 
larly in its course.
