P. Perez's Essay._ Since this exposition was written, I have had an opportunity of seeing the work, above quoted, of Chevalier Boturini, in which, speaking of the Toltec Indians, he says: After their peregrination through Asia, they reached the Continent (America), and penetrated to Hutchuetlapallan, the first city of New Spain, in which their wise men convened 130 and some years before the birth of Christ; and seeing that the civil did not agree with the astronomical year, and that the equinoctial days were altered, they determined to add in every four years one day, in order to recover the hours which were (annually) lost. And it is supposed that they effected it by counting one of the symbols of the last month of the year twice (as the Romans did with their bissextile days), without disturbing their order, because adding or taking away (a symbol) would destroy their perpetual system; and thus they made the commencement of the civil year to agree with the vernal equinox, which was the principal and governing part of the year.
