108 Sedimentary Formations 
Of course there arc scattered notices and collections in Museums. 
These, however, have not yet become historical! The Rev. J* R 
T.-Woods, is the only writer who has taken up the subject 
systematically in Tasmania, and wo are indebted to him for some 
valuable lists, of which may be mentioned lt Description of New 
Tasmanian Shells ( Proc. It. S. Tasm., 1875 and IS7(1), M and 
44 Census, with brief descriptions of Marine Shells of Tasmania 
and adjacent Islands {Proc. It. S. Tasm., read 13 Mar, 1877).” 
This, indeed, comprises long iinca of the coasts of East, South¬ 
east, and West Australia, embracing upwards of 550 distinct 
species, besides those of the Tasmanian coasts and Bass's Strait, 
collected from various sources and especially from the compilers 
personal researched: 
The late Mr. Strange was a collector of Port Jackson Shells; 
but what became of his complete collection 1 do not know. 
Some are, probably, in the Australian Museum, Sydney. Mr. 
Brazier, C.M.Z.S., the Her. It. L, King, B.A., Mr. Margraves, 
Junior, and others, have also contributed many species ; and on 
the whole, the catalogue must be an extensive one. 
Raised beaches also occur at various heights on rocky projec¬ 
tions of the coast, indicating elevation of the land, of which there 
is distinct evidence in the recent period, not only in More toil 
Bay, but near Sydney, and thence to Bass's Strait; also on both sides 
of that Strait, and as far as Adelaide and King George’s Sound. 
Mr. Selwyn gives data for assuming the elevation of the land to 
have reached occasionally 4,000 feet in Victoria, but he has no 
evidence of Tertiary Marine fossils above GOO feet. Unfortu¬ 
nately, on the Eastern coast, having no Marine Tertiaries, we 
have to found our deductions, as respects New South Wales, on 
less secure data. Yet we have here evidence of another kind, 
and pot-holed surfaces of considerable extent have been found by 
me at various heights from BOO to nearly 3,000 feet. 
In a brief memoir like the present it is impossible to quote all 
the authorities, nor has time allowed a more satisfactory digest or 
a wider range of statements. What has been thus collected is 
brought together in the design of giving a concise summary of 
the general Geology of the Colony, omitting, on account of its 
perplexity, all specific reference to the igneous rocks traversing, 
covering, transmuting, or supporting the Sedimentary deposits. 
In this Edition many new facts have been introduced with the 
view of bringing on the discoveries that have been made from 
time to time to the present period, when a new system of 
geological inquiry has been just instituted in this Colony. 
If private independent travel and research have not been able 
to accomplish more than this abstract discloses, it may be hoped 
that now the Government has commenced the work from its own 
resources, pecuniary and official, more will be accomplished than
