Number of all the active volcanoes in the Cordilleras, p. 273 ; 

 Proportions of distances with and without volcanoes, p. 277; 

 Volcanoes in North-west America north of the parallel of the 

 Kio Gila, pp. 388-403 ; Review of all volcanoes not belonging 

 to the New Continent, pp. 326-386 ; Europe, pp. 320-328 ; 

 Islands of the Atlantic, pp. 328-332 ; Africa, pp. 332-334 ; 

 Asia, continent, pp. 334-348 ; Thian-schan, pp. 337-342, and 

 Notes 567-572 ; Kamtschatka, pp. 342-348 ; East Asiatic

 Note 485; Volcanoes of Japan, pp. 356-361); South Asiatic 

 Islands, pp. 361-367 (Java, pp. 280-289); Indian Ocean, pp. 

 367-371 ; Pacific Ocean, pp. 372-386. 



Supposed number of volcanoes on the globe and their distribution 

 on continents and in islands, pp. 406-411 ; Distance of volcanic 

 activity from the sea, pp. 277, 412-413 ; Areas of depression, 

 pp. 412-415, and Note 567 ; Maars (mine-funnels), pp. 229-231 ; 

 Different modes by which, without the elevation or formation of 

 conical or dome-shaped frameworks, solid masses may arrive at 

 the surface of the Earth from its interior through fissures (basalts, 

 phonolites, and some pearl-stones ; beds of pumice seem also to 

 have proceeded not from summit-craters, but from such fissures). 

 Some streams from volcanic summits themselves consist not of a 

 connected fluid, but of disconnected scorise, and even of series of 

 expelled blocks and fragments ; there have been eruptions of 

 rocks which have not all been glowing, pp. 289, 310, 313-316, 

 323, 324.
