[Footnote 29: It is stated that the Thioux were a small body of Indians, reduced in numbers by the Chicasa, and then incorporated by the Naktche; their language possessed the sound R. If this latter statement is true, their language was neither of the Naktche nor of the Maskoki or Dakota family. In conversation the Grigras often used this word _grigra_, which also implies the use of the articulation R. Cf. Le Page du Pratz, IV, chap, ii, sect. 1; Jefferys, French Dom. in America, p. 162, and what is said of the Sháwano under Yuchi, p.]
