Of the diaries of De León and Espinosa I cite only the manuscripts in the Archivo General y Público, Mexico. These, I believe, are not otherwise available, and have not before been used except by Mr. R. C. Clark, who has recently had access to my transcripts. Of Jesus María's Relación I follow an autograph manuscript, which, however, appears to be a copy instead of the original. Of the diaries of Terán and Ramón I have had access to the originals, and of the Mezières manuscripts either to the originals or to certified official copies. My copy of the Rivera diary is from the edition printed in 1736. For the Peña and Solís diaries I have had to depend upon the copies in the Memorias. On comparing Memorias transcripts, in general, with the originals I have found that they are very corrupt and that numerous mistakes have resulted from their use. But in cases where there are no essential differences, I cite the Memorias copies, because they are more generally accessible; otherwise I cite the originals.
