[565] The epidemic of the matlazahuatl, so fatal to the Aztecs, is shown by M. de Humboldt to have been essentially different from the vómito, or bilious fever of our day. Indeed, this disease is not noticed by the early conquerors and colonists, and, Clavigero asserts, was not known in Mexico till 1725. (Stor. del Messico, tom. i. p. 117, nota.) Humboldt, however, arguing that the same physical causes must have produced similar results, carries the disease back to a much higher antiquity, of which he discerns some traditional and historic vestiges. “Il ne faut pas confondre l’epoque,” he remarks, with his usual penetration, “à laquelle une maladie a été décrite pour la première fois, parce qu’elle a fait de grands ravages dans un court espace de temps, avec l’époque de sa première apparition.” Essai politique, tom. iv. p. 161 et seq., and 179.

[568] [According to a curious document published by Icazbalceta (Col. de Doc. para la Hist. de México, tom. ii.), two of the principal caciques present on this occasion communicated secretly with Cortés, and, declaring themselves disaffected subjects of Montezuma, offered to facilitate the advance of the Spaniards by furnishing the general with paintings in which the various features of the country would be correctly delineated. The offer was accepted, and on the next visit the paintings were produced, and proved subsequently of great service to Cortés, who rewarded the donors with certain grants. But the genuineness of this paper, though supported by so distinguished a scholar as Señor Ramirez, is more than questionable.—K.]
