place in the pre-dolmen period, whenever that may have been. If the original races in Belgium had been in the habit of erecting dolmens before they were dispossessed by the intruders, we should find remains at least of them there now, as we do both north and south of that district. As the case now stands, the conclusion seems inevitable that it was after their separation that the northern and southern families, though no longer in contact, adopted, each in its own peculiar fashion, those more permanent and megalithic forms which contact with a higher civilization taught them to aspire to, without abandoning the distinctions which separated them from the more progressive Celts and the thoroughly civilized Romans.
NOTE.
The map opposite is compiled partly from the two by M. Bertrand, mentioned p. 326, and partly from one which accompanies Baron de Bonstetten's 'Essai sur les Dolmens,' 1864. It has been corrected, in so far as the scale would allow, from the information since accumulated; and may be considered as representing fairly our knowledge of the distribution of dolmens at the present day. Till, however, the Governments of this country and of Denmark condescend to take up the subject, such a map must necessarily remain imperfect in its most vital parts.
