Note 185 — Chapter II
Reading edition
Lyell's Principles of Geology, pp. 201, 714, 715; see also Somerville's Physical Geography, vol. ii. p. 71. And on this confining power of the Cordillera of the Andes, see Azara, Voyages dans l'Amérique Méridionale, vol. i. p. 33. According to Dr. Tschudi, the eastern chain is properly the Andes, and the western the Cordillera; but this distinction is rarely made. Tschudi's Travels in Peru, p. 290.
