With such well-authenticated and altogether indisputable evidence already in our possession, the additions made to our grounds for belief in the antiquity of the prehistoric dawn of Britain or Europe do not materially affect the conclusions thereby involved, though they add to the apparent duration of the human era. Whatever difficulties may seem to arise from the discoveries at Abbeville and Amiens, or the older ones at Gray’s Inn Lane, Hoxne, and elsewhere, in relation to the age of man, the chronology which suffices to embrace the ancient Caledonian whaler within the period of human history will equally adapt itself to more recent disclosures. And lying, as the Scottish relics did, almost beneath the paving of the Roman causeway, they suffice to show that discoveries relative to the British Celt of Julius Cæsar’s time, or to the Romanised Briton of Claudius or Nero, which have hitherto seemed to the antiquary to illuminate the primeval dawn, bear somewhat less relation to the period to which the Dunmyat and Blair-Drummond Moss harpoons belong, than the American aborigines of the fifteenth century do to primeval generations of the New World. The very question raised anew by such disclosures as the British drift, ossiferous caves, grave-mounds, and chance deposits reveal, is whether the ancient Celt, on whom Roman and Saxon intruded, was not himself a very recent intruder on older allophylian occupants?[18] If he was not, we are left to imagine for his race an antiquity and a history, compared with which the dreams of Merlin and the fables of Geoffrey of Monmouth are credible things.
