By far the most thorough and comprehensive researches regarding the culture and social life of the American aborigines have been made by American scholars in the _Contributions to American Ethnology_, the _Reports of the Bureau of Ethnology_, the _Reports of the Smithsonian Institution_, including those of the National Museum, and in various periodicals, notably the _American Antiquarian_ and the _American Anthropologist_. The most important of these papers for Indian marriage and family customs are Dorsey, "Omaha Sociology," in _III. Rep. of Bureau of Eth._, 205-370 (Washington, 1884), supplemented by his "Siouan Sociology," _ibid._, XV, 205-44 (Washington, 1897); McGee, "Siouan Indians," _ibid._, XV, 153-204; _idem_, "The Seri Indians," _ibid._, XVII, Part I (Washington, 1898); Mooney, "Siouan Tribes of the East," in _XVII. Rep. of Bureau of Eth._ (Washington, 1894); Riggs, "Dakota Grammar, Texts, and Ethnography," in _Contributions to N.A. Ethnology_, IX (Washington, 1893); and the elaborate work of Powers, "Tribes of California" (Washington, 1877), constituting the third volume of the same series. Some important illustrations of the matrimonial usages of the Eskimo may be found in Murdoch, "Eth. Results of Point Barrow Expedition," in _IX. Rep. of Bureau of Eth._ (Washington, 1892); Nelson, "The Eskimo about Bering Strait," _ibid._, XVIII, Part I (Washington, 1899); and Turner, "Ethnology of the Ungava District," _ibid._, XI (Washington, 1894).
