If I mistake not, I was the first to bring forward this _mode of interment_ practiced by our aboriginal nations, as a strong evidence of the unity of the American race. "Thus it is that notwithstanding the diversity of language, customs and intellectual character, we trace this usage throughout both Americas, affording, as we have already stated, collateral evidence of the affiliation of all the American tribes."--Crania Americana, p. 246, and pl. 69. Mr. Bradford in his valuable work, _American Antiquities_, has added some examples of the same kind; and the Chevalier D'Eichthal has also adduced this custom, in connexion with some traces of it in Polynesia, to prove an exotic origin for a part at least of the American race. See _Mémoires de la Société Ethnologique de Paris_, Tome II, p. 236. Whence arose this conventional position of the body in death? This question has been often asked and variously answered. It is obviously an imitation of the attitude which the living Indian habitually assumes when sitting at perfect ease, and which has been naturally transferred to his lifeless remains as a fit emblem of repose.

[8-+] I have been looking to Dr. Dickerson, of Natchez, for more complete details derived from the tumuli of that ancient tribe which formed a link between the Mexican nations on the one hand, and the savage hordes on the other. Dr. Dickerson is amply provided with interesting and important materials for this inquiry, which we trust he will soon make public. [8-++] The skull brought me from Ticul by Mr. Stephens, is that of a young female. It presents the natural rounded form; which accords with the observation of M. D'Orbigny, (L'Homme Americain,) that the artificial moulding of the head among some tribes of Peruvians was chiefly confined to the men. [8-§] Travels in Central America, vol. ii, p. 311.

[12-++] I am aware that the walls of the ancient Mexican and Peruvian edifices are often vertical; but where this is the case the pyramidal form is attained by piling, one on the other, successive tiers of masonry, each receding from the other and leaving a parapet or platform at its base.
