the languages of Mexico; (2) notes on the immigration of the tribes of
Mexico; (3) geography of the languages of Mexico.

The author states that he has no knowledge whatever of the languages he
treats of. All he attempts to do is to summarize the opinions of others.
His authorities were (1) writers on native grammars; (2) missionaries;
(3) persons who are reputed to be versed in such matters. He professes
to have used his own judgment only when these authorities left him free
to do so.

His stated method in compiling the ethnographic map was to place before
him the map of a certain department, examine all his authorities bearing
on that department, and to mark with a distinctive color all localities
said to belong to a particular language. When this was done he drew a
boundary line around the area of that language. Examination of the map
shows that he has partly expressed on it the classification of languages
as given in the first part of his text, and partly limited himself to
indicating the geographic boundaries of languages, without, however,
giving the boundaries of all the languages mentioned in his lists.
