It is not yet suitable to give here a complete list of all the ancient nations, who have, or may have colonized the Western hemisphere: this can only be done afterwards as a result of the instituted enquiries on the subject. Meantime I state as highly probable, even by mere analogy, that all the nearest nations of the Atlantic or Pacific Oceans, in the Eastern hemisphere, have either visited or colonized the Americas; particularly from the east, the bold navigators, Atlantes, Pelagians, Phenicians, Lybyans, Etruscans, &c., and from the west the ancient tribes of Tartars and Chinese, the Polynesians, &c. We shall throughout these historical outlines find ample proofs of this fact, exploding the erroneous belief that a single nation could have populated the whole of the Western Hemisphere. It shall appear also that these early settlers must have brought along many foreign tribes, as auxiliaries, vassals or slaves. In my Atlantic Journal of 1832 will be found a kind of classification of the ancient nations of both Americas, divided into 25 groups, 14 in North, 11 in South America. But this first attempt, cannot be perfect: it requires a close study of all the American languages, before we can ascertain correctly all their mutual affinities, and reduce each to the real parent group. Meantime this attempt, and the further correction of it in this work, will become very useful historical bases. I give therefore the list of the 25 groups, with a well known nation and language as the type, to which others may be gradually reduced. In North America 1. _Uski_ or _Innuit_, type the Esquimaux. 2. _Ongwi_, type the Hurons and Iroquois. 3. _Linni_, type the Lanapi or Delawares. 4. _Wacash_, type the Chopunish, and Nutkas. 5. _Skerreh_, type the Panis. 6. _Nachez_, type the Cados and Chetimachas. 7. _Capaha_, types the Washas or Ozages, and Dacotas or Sioux. 8. _Chactah_, types the Chactahs and Chicasas. 9. _Otali_, Tzulukis or Cherokis. 10. _Atalan_, type the Tarascas. 11. _Otomi_, type the Otomis. 12. _Anahuac_, type the Aztecas. 13. _Maya_, types the Mayas and Huaztecas. 14. _Chontal_, type the Tzendals and Chols. In South America 15. _Aruac_, types the Haytians, Aruacs, Taos, &c. 16. _Calina_, types the Caribs and Tamanacs. 17. _Puris_, type the Maypuris. 18. _Yarura_, types the Guaraos and Betoys. 19. _Cuna_, type the Dariens. 20. _Mayna_, type the Panos. 21. _Maca_, type the Muyzcas. 22. _Guarani_, type the Tupis and Omaguas. 23. _Mara_, type the Quichuas and Aymaras. 24. _Lulé_, types the Vilelas and Mbayas. 25. _Chili_, type the Chilians. Notwithstanding the condensed form of these outlines, the ample materials to be brought together, will extend them perhaps beyond the desirable limits. In order to lessen this difficulty and yet omit nothing that is new or important, the work will be divided into three series.
