Note 10 — Chapter I · ANCIENT MEXICO—CLIMATE AND PRODUCTS—PRIMITIVE RACES—AZTEC EMPIRE
Reading edition
About 62° Fahrenheit, or 17° Réaumur. (Humboldt, Essai politique, tom. i. p. 273.) The more elevated plateaus of the table-land, as the Valley of Toluca, about 8500 feet above the sea, have a stern climate, in which the thermometer, during a great part of the day, rarely rises beyond 45° F. Idem (loc. cit.), and Malte-Brun (Universal Geography, Eng. trans., book 83), who is, indeed, in this part of his work, but an echo of the former writer.
