THE GEOLOGICAL SOCIETY OF LONDON. 
Vo. III. 1840. No. 70. 
April 29.— Abraham Gesner, Esq., residing in Nova Scotia; the 
Rey. James Cartmell, M.A., Christ Church, Cambridge; and Alger- 
non Sydney Aspland, Esq., Lamb’s Buildings, Temple, were elected 
Fellows of this Society. 
A paper was first read, “ On a few detached places along the coast 
of Ionia and Caria; and on the island of Rhodes ;” by William John 
Hamilton, Esq., Sec. G.S. 
The localities described in this paper are, 1. Fouges (anc. Phocea); 
2. Ritri (anc. Erythre); 3. Sighajik (anc. Teos); 4. Scalanuova, 
near Ephesus; 5. Boodroom (anc. Halicarnassus); 6. Cnidus; 7. 
Island and shores of the Gulf of Syme; and 8. Rhodes. : 
1. Fouges is situated in a small bay at the northern extremity of 
the Gulf of Smyrna, and all the formations in its neighbourhood ex- 
amined by Mr. Hamilton are volcanic. On the north side of the 
bay, a range of hills, from 300 to 400 feet high, extends several miles 
to the eastward, and consists in the uppermost part, of beds of smooth 
semivitrified red and gray trachyte, containing numerous cavities 
lined with mammillated chalcedony. The trachyte passes down 
wards into a soft, white, pumiceous sandy rock. The greater part 
of the hills to the north of the bay are composed of the same for- 
mation, traversed, in several places by north and east, narrow trap- 
dykes, which have altered the adjacent rocks into an imperfectly 
banded jasper. About one mile to the north-east of Fouges, Mr. 
Hamilton noticed a mass of black hornstone, and to the west and 
north-west, near the water’s edge, trappean and amygdaloidal rocks, 
overlaid by the pumiceous sandstone. ‘ 
2. fitra is situated on the shores of the bay of Erythrze, opposite 
the island of Scio; and the geological structure of the neighbouring 
district consists of red crystalline, apparently stratified trachyte, and 
of blue or gray, more or less, crystalline limestone, with associated 
sandstone. The two latter rocks are of anterior date to the trachyte, 
but Mr. Hamilton could not determine their relative geological age, 
as they appear to be destitute of organic remains. The beds of lime- 
stone are sometimes vertical. On the shore near the Acropolis the 
author noticed also vertical strata of indurated shale and jasper, and 
near the juncture of the trachyte and limestone, to the north of the 
Acropolis, that the calcareous beds were much shattered. The two
