Arte de la lengua cahita (Mexico, 1737), the only printed grammar of the language of the Yaqui and Mayo

A grammar and vocabulary of Cahita, the language of the Yaqui and Mayo rivers, written by a Jesuit of the Sinaloa mission and printed at Mexico in 1737 with a catechism by Tomas Basilio. Its editor in 1890 could find only three copies and knew of no other grammar of the language ever published. The book refuses the Latin category of the frequentative, lists the letters Cahita lacks, and says in its dedication that it exists to make preaching quicker.
