Note 25 — Chapter VI · NATIONS, WHETHER PROGRESSING OR STAGNATING, ARE INDEPENDENT OF THE REGIONS IN WHICH THEY LIVE

The special construction of these tumuli and the numerous instruments and utensils they contain are occupying the attention of many eminent American antiquaries. It is impossible to doubt the great age of these monuments. Squier is perfectly right in finding a proof of this in the mere fact that the skeletons discovered in the tumuli fall to pieces when brought into the slightest contact with the air, although the conditions for their preservation are excellent, so far as the quality of the soil is concerned. On the other hand, the bodies which lay buried under the cromlechs of Brittany, and which are at least 1800 years old, are perfectly firm. Hence we may easily imagine that there is no relation between these ancient inhabitants of the land and the tribes of the present day—the Lenni-Lenapes and others. I must not end this note without praising the industry and resource shown by American scholars in the study of the antiquities of their continent. Finding their labours greatly hindered by the extreme brittleness of the skulls they had exhumed, they discovered, after many abortive attempts, a way of pouring a preparation of bitumen into the bodies, which solidifies at once and keeps the bones from crumbling. This delicate process, which requires infinite care and quickness, seems, as a rule, to be entirely successful.
