Note 48 — Chapter VIII
Reading edition
It appears by the measurements of Mr. Pentland in the Peru-Bolivian Andes, that many of their passes are higher than in the equatorial portion of the chain. The passes of Rumihuasi, on the high road from Cusco to Arequipa, of Toledo (between Arequipa and Puno), of Gualillas and Chullunquiani (between Arica and La Paz), all in the Western Cordillera, attain the respective elevations of 16,160, 15,790, 14,750, and 15,160 feet;—whilst in the Eastern or Bolivian Cordillera the passes of Challa (between Oruro and Cochabamba), of Pacuani (between La Paz and Coröico), of Pumapacheta (between the lake of Titicaca and the affluents to the Amazon), of Vilcañoto (between the valley of the Collao and that of the river Yucay), rise to heights of 13,600, 15,350, 13,600, and 14,520 English feet.
