pure condition up to the present epoch, Mixtec is spoken in the 
western and northern parts of Oajaca, and also in the adjoining portions 
of the state of Guerrero, and is closely related to the Chuchon, 
Amusgo, Cuitlatec, and other idiomatic forms of speech heard in these 
parts. The Mixtec proper is divided into upper and lower Mixtec, the 
majority of the Pueblos speaking the upper Mixtec, or Mixteco alto. 
In former times the Pueblos of Tanguitlan and of Tepuzculula were 
considered to speak the typical and purest form of the upper Mixtec. 
The Spanish grammar (Arte) of the Dominican father Antonio de los 
Reyes, printed in 1593, represents the dialect heard at Tepuzculula at 
that time, and has just been reédited by Leon Reinisch, at the 
expense of Count Hyacinthe de Charencey, in the eighteenth volume 
of the ‘* Actes de la Société Philologique de Paris,’’ 1890, making 93 
octavo pages. The prologue which precedes the work (eight pages) 
contains much that is valuable upon the ethnography and dialects of 
the Mixtec people. : 
The same eighteenth volume contains a Confessonario en len 
Mixe, by the Dominican father Augustin de Quintana, also republished 
at M. de Charencey’s expense, and filling 331 pages. It isa reprint 
from the edition of LaPuebla, Mexico, 1733, and besides the devo- 
tional texts embodies a vocabulary of the parts of the human body, 
the names of relationships, the numerals, and some grammatic infor- 
mation. Mije or Mixe is spoken in the eastern parts of Oajaca State.
