ed that human bones would yet be
found in the midst of the flint implements, and in 1863 he claimed that
this prophecy had been fulfilled by the discovery at Moulin Quignon of
a portion of a human jaw deep in the early Quaternary deposits. But his
triumph was short-lived: the opposition ridiculed his discovery; they
showed that he had offered a premium to his workmen for the discovery
of human remains, and they naturally drew the inference that some
tricky labourer had deceived him. The result of this was that the men
of science felt obliged to acknowledge that the Moulin Quignon discovery
was not proven.

But ere long human bones were found in the deposits of the early
Quaternary period, or indeed of an earlier period, in various other
parts of the world, and the question regarding the Moulin Quignon relic
was of little importance.

We have seen that researches regarding the existence of prehistoric
man in England and on the Continent were at first mainly made in the
caverns; but the existence of man in the earliest Quaternary period
was confirmed on both sides of the English Channel, in a way even
more striking, by the close examination of the drift and early gravel
deposits. The results arrived at by Boucher de Perthes were amply
confirmed in England. Rude stone implements were found in terraces a
hundred feet and more above the levels at which various rivers of Great
Britain now flow, and under circumstances which show that, at the time
when they were deposited, the rivers of Great Britain in many cases were
entirely different from those of the present period, and formed parts
of the river system of the European continent. Researches in the high
terraces above the Thames and the Ouse, as well as at other points in
Great Britain, placed beyond a doubt the fact that man existed on the
British Islands at a time when they were connected by solid land
with the Continent, and made it clear that, within the period of the
existence of man in northern Europe, a large portion of the British
Islands had been sunk to depths between fifteen hundred and twenty-five
hundred feet beneath the Northern Ocean,--had risen again from the
water,--had formed part of the continent of Europe, and had been in
unbroken connection with Africa, so that elephants, bears, tigers,
lions, the rhinoceros and hippopotamus, of species now mainly extinct,
had left their bones in the same deposits with human implements as far
north as Yorkshire. Moreo
