This is a copy of Moran's "libro grande" (1625-1650), and includes two versions of the grammar (in different hands), confessional materials, and a vocabulary of 500 words which has been added to the others. The first three pages are a narrative of Spanish missions (1689-1692) by Thomas Murillo. For description, see: D. G. Brinton. "Notice of some manuscripts..." American Journal of Science, 2nd Series, 1869, v. 47, 222-230.
