Paper, 'Notes on the microscopic structure of some rocks from the Andes of Ecuador, collected by E Whymper. No III. Cotopaxi and Chimborazo' by T G [Thomas George] Bonney

Description

Bonney writes: 'In regard to these two important volcanic mountains of the Ecuadorian Andes, Mr Whymper has favoured me with some descriptive notes, which appear to me of so much interest that I incorporate them with but slight modification into my paper [...] Two volcanoes in Ecuador—Sangai and Cotopaxi—are always in a state of activity, and, of these two, the latter is the higher and the more important mountain. Cotopaxi, according to my observations with mercurial barometer on its summit, is 19,650 feet high, and it is the second in altitude of the Andes of Ecuador, being inferior only to Chimborazo.'
