xxvi Physical and Geognostic Suggestions, 



or Atiti, which is more generally known as the volcano of the 

 island of Amboyna, ever poured out anything except hot 

 mud (1674), or whether it should be merely classed as a 

 solfatara. The main group of the South Asiatic Islands 

 is connected through the Moluccas and the Philippines with 

 the Papua and Pellew islands, and the Caroline Archipelago 

 of the South Sea. 



The most important geological fact to be remarked with 

 reference to the island of Formosa, abounding in mineral 

 coals, is the break in the line of direction of the open vents, 

 when, instead of N.E. to S.W., the central line follows the 

 meridian line, which it pursues nearly as far as 6° S., passing 

 through Formosa and the Philippine Islands (Luzon and 

 Mindanao), respecting which deviation nothing certain is 

 known, and in which region every mountain of conical shape, 

 or outline is invariably set down as a volcano, even though 

 there should be no indications of a crater. The Sooloo Ar- 

 chipelago forms the connecting link between the islands of 

 Borneo and Mindanao, the long, narrow island of Palawan, 

 constituting that between Borneo and Mindoro. 



The Island of Yesso, separated from that of Niphon by the 

 Straits of Saugar, or Tsugar, and from the islands of Krafto 

 (Saghalien) and Tschoka, or Tarakai, by the Straits of La 

 Perouse, connects, through its North Eastern Cape, with the 

 archipelago of the Kuriles. From Broughton's Southern Vul- 

 can Bay up to its northernmost point, Yesso is traversed by 

 an uninterrupted range of volcanoes — a fact the more worthy
