[34-1] Since writing the text I have received the admirable work of Dr. von Martius, _Beiträge zur Ethnographie und Sprachenkunde Amerika's zumal Brasilians_, Leipzig, 1867, in which I observe that that profound student considers that there is no doubt but that the Island Caribs, and the Galibis of the main land are descendants from the same stock as the Tupis and Guaranis. [35-1] _Comptes Rendus_, vol. xxi. p. 1368 sqq. [35-2] The two best authorities are Daniel Wilson, _The American Cranial Type_, in _Ann. Rep. of the Smithson. Inst._, 1862, p. 240, and J. A. Meigs, _Cranial Forms of the Amer. Aborigs._: Phila. 1866. They accord in the views expressed in the text and in the rejection of those advocated by Dr. S. G. Morton in the Crania Americana.

An intuition common to the species.--Words expressing it in American languages derived either from ideas of above in space, or of life manifested by breath.--Examples.--No conscious monotheism, and but little idea of immateriality discoverable.--Still less any moral dualism of deities, the Great Good Spirit and the Great Bad Spirit being alike terms and notions of foreign importation.
