[XIII-13] Landa, Relacion, pp. 44-8. 'Le nom des Tutul-Xiu paraît d'origine nahuatl; il serait dérivé de totol, tototl, oiseau, et de xíuitl, ou xíhuitl, herbe, etc. En ceci il n'y aurait rien d'extraordinaire, puisqu'ils sortaient de Tula ou Tulapan, cité qui aurait été la capitale des Nahuas ou Toltèques après leur victoire sur Xibalba.' Brasseur, in Id., p. 47. See also Herrera, dec. iv., lib. x., cap. ii., iii.; Torquemada, tom. iii., p. 132; Cogolludo, Hist. Yuc., pp. 178, 182; Morelet, Voyage, tom. i., p. 271; Gallatin, in Amer.

[XIII-17] See [vol. ii., pp. 762-5].

[XIII-18] In his Hist. Nat. Civ., Brasseur follows this system and repeatedly gives 174 (171 on [p. 228] of this volume is a misprint) as the date of this migration, using it indeed to fix the date of the migration of the Toltecs and Quichés from Tulan; but he adopts the other theory in his notes to Landa's work.

[XIII-19] Reckoning an epoch as 24 years, the migration lasted from 173 to 270, or 97 years instead of 81, as in the text. Perez has it from 144 to 217, or 73 years, which agrees neither with the text nor with his own theory.
