convenient to try to resume, in as few words as possible, the principal results we have arrived at from the preceding investigation.
First, with regard to their age. It seems that the uncivilized, ancestral-worshipping races of Europe first borrowed from the Romans — or, if any one likes, from the Phœnicians or Greeks of Marseilles — the idea of using stone to accentuate and adorn the monuments of their dead. In like manner, it certainly was from the Bactrian Greeks that the Indians first learned the use of stone as a building material. How early the Eastern nations adopted it in its rude form we do not know. In its polished form it was used as early as the middle of the third century B.C., but we have no authentic instance of the rude form till at least a century or two after Christ; but, once introduced, its use continued to the present day. Its history in the West seems somewhat different. The great chambered tumuli at Gavr Innis, and others in France, as well as those at Lough Crew, in Ireland, seem to belong to a time before the Romans occupied the states of Western Europe; but no stone monument of this class has yet made out its claim to an antiquity of more than two centuries, if so much, before the Christian era. Some of those in Greece about Mycenæ, and those at Saturnia, may be earlier, but they are as yet undescribed scientifically, and we cannot tell. From shortly before the Christian era, till the countries in which they are found became entirely and essentially Christian, the use of these monuments seems to have been continual, whenever a dolmen-building race — or, in other words, a race with any taint of Turanian blood in their veins — continued to prevail. This, in remote corners of the world, seems to have extended in France and Britain down to the eighth or ninth century. In Scandinavia it lasted down to the eleventh or twelfth, and sporadically, in out-of-the-way and neglected districts, as late both in France and Great Britain.
These results do not, of course, touch the age of the earthen tumuli or barrows, for the determination of whose age no scale has yet been invented; still less do they approach the question of the antiquity of the Cave men or the palæolithic stone implements,
