The analysis of the religious sentiment I offer is an inductive one, whose outlines were furnished by a preliminary study of the religions of the native race of America, a field selected as most favorable by reason of the simplicity of many of its cults, and the absence of theories respecting them. This study was embodied in "The Myths of the New World; a Treatise on the Symbolism and Mythology of the Red Race of America" (second edition, N. Y. 1876).
