Note 156 — Chapter VIII

"Linguistic Stocks of South American Indians," in AA, new series, xv (1913); also, Wissler, The American Indian, pp. 381-85, listing eighty-four stocks. It must be borne in mind, however, that the tendency of minute study is eventually to diminish the number of linguistic stocks having no detectable relationships, and that, in any case, classifications based upon cultural grade are more important for the student of mythology than are those based upon language alone.
