ON ITS EXTERIOR. VOLCANOES. 275 



adjacent volcano of Tolima (4 55' N. lat., according to 

 Acosta) ; Purace and Sotara near Popayan (N. 2) ; the 

 Volcanes de Pasto, Tuquerres, and Cumbal (K 2 20' to 

 50') ; and the series of volcanoes from Pichincha near 

 Quito to the uninterruptedly active Sangay (from the 

 equator to 2 S.). This last-named subdivision of the 

 entire group is not particularly distinguished among 

 the volcanoes of the New World, either by its great 

 length or by the number it comprises ; nor does it, as 

 we now know, contain the highest summit : for Aconcagua 

 in Chili (S. lat. 32 39'), 23,003 feet .high according to 

 Kellett, 23,909 feet according to Fitz Koy and Pentland, 

 as well as the Nevados of Sahama (22,349 feet), Parina- 

 cota (22,029 feet), Grualateiri (21,959 feet), and Poma- 

 rape (21,699 feet), all between 18 V and 18 25' S. 

 latitude, are all believed to be higher than Chimborazo 

 (21,422 feet). Yet it is the volcanoes of Quito which, 

 among all the volcanoes of the new continent, enjoy the 

 most wide-spread renown; for it is to this part of 

 the chain of the Andes, and to these highlands of Quito, 

 that the remembrance of arduous labours for important 

 objects in astronomical, geodesical, optical, and barome- 

 trical operations, attaches itself, in connection with the 

 brilliant names of Bouguer and La Condamine. Where 

 intellectual associations prevail, where a multitude 

 of ideas have been awakened which have led simulta- 

 neously to the enlargement of several sciences, fame 

 remains long attached to the locality. Thus it has been 

 in the Swiss Alps with Mont Blanc, not on account of 

 its height, in which respect it surpasses Monte Eosa 

 only by 557 feet, nor on account of dangers overcome in 

 its ascent, but by reason of the value, number.
