[17] See M. Ternaux-Compans' Original Memoirs of the discovery of America—(Conquest of Mexico, p. 451)—Compans publishes in this, for the first time, an official list sent between 1522 and 1587 by the viceroys of New Spain to the mother country. The PESOS of gold, must be multiplied by a mean of eleven dollars and sixty-five cents in order to give their value in dollars. See Banker's Magazine, ut antea, p. 594, in note. See Prescott's History of the Conquest of Mexico, vol. i., 320. Raminez, in his notes on the Spanish translation of Prescott's History of the Conquest rates the peso de oro at two dollars and ninety-three cents. This result is reached by a long financial calculation and course of reasoning. See La Conquista de Mejico, vol. ii., at p. 89 of the notes at the end of the volume.
[18] This is Humboldt's estimate in the essay cited in this section. We think it rather too large, yet give it upon such high authority. See our general table of Mexican coinage.
