It is unknown whether the volcanos of the north-west coast 

 have recently made any eruption. 



Orizaba is 17,300 feet high ; the streams of lava observed on 

 the sides of the mountain remove every doubt as to its volcanic 

 nature ; but no recent eruptions are known of. 



Popocatepetl has smoked ever since the conquest of Mexico. 

 Cortes relates indeed, that he ordered ten of his most courageous 

 companions to reach the summit, and to discover the secret of its 

 smoking, which he wished to communicate to Charles V. This 

 volcano is always burning, but it has projected lava from time 

 immemorial. Its height measured by M. de Humboldt is 17,600 

 feet. 



The volcano of Tuxtht is situate to the south-west of Veracruze. 

 Its last very considerable eruption occurred in 1793. The 

 ejected ashes were then carried as far as Perote, a distance, in a 

 straight line, of 57 leagues. 



Xorul/o. — M. de Humboldt remarks, that the catastrophe 

 which gave rise to the volcano of Xorullo, is, perhaps, one of the 

 most extraordinary physical revolutions which the annals of 

 our planet contain. In the middle of a continent, at 36 leagues 

 distance from any active volcano, the earth rose to the extent of 

 three or four square miles in the form of a bladder, on the night 

 of the 28th and on the 29th of September, 1759. In the centre 

 of a thousand inflamed cones, six mountains from 1,300 to 1,700 

 feet high above the original level of the surrounding country, sud- 

 denly arose. The principal of them is Xorullo, the height of 

 which is 1 ,700 feet. Its eruptions continued without cessation 

 until the month of February, 1 760. The subterranean fire is now 

 very active. 



The volcano of Colima, the most western of those in New 

 Spain, ejects now hardly any thing but ashes and smoke. Its 

 height is about 1,000 feet. 



M. de Humboldt has made the important observation, that the 

 Peak of Orizaba, Popocatepetl, Colima, and other extinct vol-
