DETAILED LIST OF SPECIMENS. 
The specimens mentioned in the following list have been 
compared with some of those of England and other countries, 
principally in the cabinets of the Geological Society, and of 
Mr. Greenough ; and with a collection from part of the con- 
fines of the primitive tracts of England and North Wales, 
formed by Mr. Arthur Aikin, and now in his own posses- 
sion. Captain King’s collection has been presented to the 
Geological Society; and duplicates of Mr. Brown’s speci- 
mens are deposited in the British Museum. 
Rodd’s Bay, on the East Coast, discovered by Captain 
King, about sixty miles south of Cape Capricorn *. — Red- 
dish sand-stone, of moderately-fine grain, resembling that 
which in England occurs in the coal formation, and beneath 
it (mill-stone grit.) A sienitic compound, consisting of a 
large proportion of reddish felspar, with specks of a green 
substance, probably mica; — resembling a rock from Shap 
in Cumberland. 
Cape Clinton, between Rodd’s Bay and the Percy Islands. 
— Porphyritic conglomerate, with a base of decomposed fel- 
spar, enclosing grains of quartz and common felspar, and 
some fragments of what appears to be compact epidote; 
* In Captain King’s collection are also specimens found on the 
beach at Port Macquarie, and in the bed of the Hastings River, 
of common serpentine, and of botryoidal magnesite, from veins in 
serpentine. The magnesite agrees nearly with that of Baudissero, 
in Piedmont. (See Cleaveland’s Mineralogy, 1st edition, p. 345.)
