Grecian Archipelago. — Proceeding westwards, we reach the 

 Grecian Archipelago, where Santorin, afterwards to be de- 

 scribed, is the grand centre of volcanic action. 



It was Von Buch's opinion that the volcanos of Greece 



were arranged in 



JSLN.W 



that they afforded the only example in Europe of active 

 volcanos having a linear direction ; but M. Virlet, on the

during the French expedition to the 

 there is one determinate line of direction for the volcanic 

 phenomena in Greece, whether we follow the points of erup- 

 tions, or the earthquakes, or any other signs of igneous 



agency .% 



Macedonia, Thrace, and Epirus have always been subject 



to earthquakes, and the Ionian Isles are continually con- 

 vulsed. 



Respecting Southern Italy, Sicily, and the Lipari Isles, it 



is unnecessary to enlarge here, as I shall have occasion again 

 to allude to them. I may mention, however, that a band of 

 volcanic action has been traced by Dr. Daubeny across the 

 Italian Peninsula, from Ischia to Mount Vultur, in Apulia, 

 the commencement of the line being found in the hot springs 

 of Ischia, after which it is prolonged through Vesuvius to 

 the Lago d'Ansanto, where gases similar to those of Vesuvius 

 are evolved. Its farther extension strikes Mount Vultur, a 

 lofty cone composed of tuff and lava, from one side of which 

 carbonic acid and sulphuretted hydrogen are emitted. §
