:j24 the BOTIVM OF THE SEA. 



In the island of Bima, or 8umbawa, there is a very 

 active volcano, named the Tomboro. In 1821 such 

 a movement of the sea occurred here, that the island 

 was partly submerged, and vessels at anchor in the 

 port were thrown to a great distance on tlie shore. 

 Many were landed even on the roofs of tlie houses. 

 Tomboro itself remained calm during the time, but a 

 volcanic mountain to the north-east of it threw up 

 stones and cinders in the midst of a torrent of vapours. 

 The earthquake was felt in the neighbouring isles, at 

 Celebes, and even at Macassar, where the same de- 

 vastation occurred as at Bima. These two places 

 are nevertheless separated by an arm of the sea 100 

 leagues broad. 



/. Products of Submarine Volciinoes — How they differ from the 

 prudufts of Subuerial Volcanoes. 



A very close analogy has been observed between 

 the products of all the volcanoes on the earth's sur- 

 face. Submarine volcanoes are no exception to the 

 general rule. One and the same cause produces all 

 these phenomena. The nature of the medium into 

 which they eject their gas and igneous matter can 

 alone occasion any difference in the character of the 

 eruption.
