raene through a narrow gorge between hills of mica schist. A coul6e, 

 probably derived from the most western of the three newest cones, 

 has flowed through this gorge and expanded over the plain at Adala. 

 The Hermus, thus impeded in its course, appears to have flown over 

 the lava, the surface of which is smooth and bears a stratum of peb- 

 bles. In course of time the river has worn a channel between the 

 mica slate and the lava to the depth of 80 feet, completely cutting 

 through the coulee ; yet so compact is the lava which has escaped the 

 action of the stream of water, that it exhibits not the slightest tendency 

 to decomposition. 



The author then points out the strong resemblance between the 

 structure of the Catacecaumene and the volcanic district of Central 

 France. In each country are extensive lacustrine formations, cones 

 of scoriae of different ages, coulees, sometimes forming plateaux on 

 the summits of isolated hills, at others continuous streams, and thick 

 beds of lava worn through by the action of running water. 



10, Modern aqueous deposits. — Under this head a description is 

 given of the travertine deposited by hot springs between the foot of 

 Mount Olympus and Broussa, forming an accumulation 2 miles in 

 length, and at the latter locality half a mile in breadth and 100 feet 

 high. The water has a temperature of 184° of Fahrenheit, but at 

 present there are no springs except those at the foot of Mount Olym- 

 pus. 



A description was next given of the changes which have been pro- 

 duced by sedimentary matter deposited near the mouths of the rivers. 

 Thus the island of Lade, once the scene of a sea-fi^ht between the 

 Persians and the lonians, is now a hill in the midst of a plain j the 

 Latmic Gulf is changed into an inland lake j the once flourishing 

 town of Miletus, losing its hiirbour, is become a heap of ruins ; the 

 port of Ephesus is converted into a stagnant pool ; and the delta of 

 the Hermus threatens in a few centuries to destroy the harbour of the 

 prosperous city of Smyrna. 



The memoir concluded with the description of a recent lacustrine 

 deposit in the valley of the Rhyndacus above Kirmasteu, which appears 

 to have been for the greater part removed by the action of that river, 

 only detached platforms, 50 or 60 feet high, being left on the sides 

 of the valley.

Nov, 1, 1836.— Specimens of the Spartina glabra, a grass new to 

 the British Flora, were presented by Dr. Bromfield, by whom it was 

 discovered during the past summer on the muddy banks of the river at 

 Southampton, growing in great abundance intermixed with the S. 

 stricta. The species had been previously found only in North America. 

 It is now in such plenty in the Southampton station that, if really in- 

 troduced by ballast or other means, it must have been long since 

 naturalized.
