Note 13 — Chapter I · ANCIENT MEXICO—CLIMATE AND PRODUCTS—PRIMITIVE RACES—AZTEC EMPIRE
Reading edition
Humboldt, Essai politique, tom. ii. pp. 29, 44-49.—Malte-Brun, book 85. This latter geographer assigns only 6700 feet for the level of the Valley, contradicting himself (comp. book 83), or rather Humboldt, to whose pages he helps himself plenis manibus, somewhat too liberally, indeed, for the scanty references at the bottom of his page.
