stated in the Table. For, on account of our intercalation of one day every bissextile year, the Mexican year receded, as compared with ours, one day every four years. This correction must therefore be made, whenever a comparison of the dates is wanted for any other than the first year of the cycle. The Mexican intercalation of 13 days at the end of the cycle of 52 years made again the first year of every cycle correspond with our year, in the manner stated in the Table.
Another correction is again necessary, when we have a Tescocan instead of a Mexican date. For the first year of the Mexican cycle was 1 Tochtli, and that of Tescoco was 1 Acatl; which caused a difference now of three, now of ten days in their calendars, which in every other respect were the same. Both corrections appear in the second Table.—Trans. Amer. Ethnol. Soc., vol. i, p. 114. Tables C1, and C2.
