is not the effect of one single heaving up : most 

 of them appear to consist of isolated masses, 

 which have been progressively united together*. 

 The matter has not been emitted from one mouth, 

 but from several : so that a single island of 

 small extent contains a whole system of volca- 

 noes -f? 3 regions purely basaltic, and others covered 

 with recent lavas. The volcanoes still burning 

 are those of St. Vincent, St. Lucia, and Guada- 

 loupe. The first threw out lavas in 1718 and 

 1812 : in the second there is a continual forma- 

 tion of sulphur by the condensation of vapours, 

 which issue from the crevices of an ancient 

 crater. The last eruption of the volcano of 

 Guadaloupe took place in 1797. The Solfatara 

 of St. Christophers was still burning in 1692, 

 At Martinico, Vauclin, Montagne Pel6e, and 

 the crater surrounded by the five paps of Carbet, 

 must be considered as three extinguished vol- 

 canoes. The effects of thunder have been often 

 confounded in that place with subterranean fire. 

 No good observation has confirmed the sup- 

 posed eruption:}; of the 22nd of January, 1792, 

 The group of volcanoes in the Caribbee islands
