38 Volcanoes in the Bay of Bengal. 



Streams of indurated lava are seen to proceed from these 

 chiefly towards the east side of the island. It is said to have 

 been on fire about 1828 or 1830. One of the peaks in which 

 it terminates, exhibits the remains of two craters of about 

 25 feet in diameter, — both have fallen in. A single crater 

 of much more recent formation than the others, appears in 

 the northern peak of Gibbel Teir, seems the northernmost of 

 the volcanoes in the Red Sea, and probably limits the band. 

 We have no information whatever, so far as I know, 

 as to any volcanoes in the interior of Arabia, or to the 

 northward. In his description of the sulphur mines of 

 Cummer (Khamir) opposite Kishmi, in the Persian Gulf, 

 Lieutenant Jenkins* does not state whether the country is 

 volcanic or gypseous, or both ; and Lieutenant Fullarton, 

 who presented specimens of crystallized sulphur")" to the 

 Bombay Asiatic Society in 1851, leaves us equally in the 

 dark. We know that gypsum abounds in it. An extinct vol- 

 cano, called Mount Nimrod, is described by M. Chaucourtois, J 

 as existing near the Salt Lake Vau, in Armenistan, on the 

 frontiers of Persia, between the 38th and 39th degrees of 

 latitude. On the banks of the Euphrates, near the city of 

 Hit, in the region of the Petroleum wells, Dr Winchester 

 found scoriae on the summit of a detached hill, about 80 feet 

 above the level of the plain ; but no other volcanic appearance 

 was observed. §
