All of them are from a MS. volume in the library of the University of Mexico, entitled Cantares de los Mexicanos y otros opusculos, composed of various pieces in different handwritings, which, from their appearance and the character of the letter, were attributed by the eminent antiquary Don Jose F. Ramirez, to the sixteenth and seventeenth centuries.

The copy I have used is that made by the late Abbe Brasseur (de Bourbourg).  It does not appear to be complete, but my efforts to have it collated with the original have not been successful.  Another copy was taken by the late well-known Mexican scholar Faustino Chimalpopoca, which was in the possession of Senor Ramirez and sold at the vendue of his books in 1880.  It is No. 511 of the catalogue.

The final decision of the age of the poems must come from a careful scrutiny of the internal evidence, especially the thoughts they contain and the language in which they are expressed.  In applying these tests, it should be remembered that a song may be almost wholly ancient, that is, composed anterior to the Conquest, and yet display a few later allusions introduced by the person who preserved it in writing, so as to remove from it the flavor of heathenism.  Some probable instances of this kind will be pointed out in the Notes.

The songs are evidently from different sources and of different epochs.  There are two notes inserted in the MS. which throw some light on the origin of a few of the poems.  The first is in connection with No.  XII.  In my copy of the MS, the title of this song is written twice, and between the two the following memorandum appears in Spanish: 

“Ancient songs of the native Otomis, which they were accustomed to sing at their festivals and marriages, translated into the Mexican language, the play and the spirit of the song and its figures of speech being always retained; as Your Reverence will understand, they displayed considerable style and beauty, better than I can express with my slight talent; and may Your Reverence at your convenience approve and be entertained by them, as a skilled master of the tongue, as Your Reverence is.”

From its position and from the titles following, this note appears to apply only to No.  XII.

The second note is prefixed to No.  XIV, which has no title.  It is in Nahuatl, and reads as follows:—­
