By J. R. Dakyns, M.A., of H.M. Geological Sun r ey. 
O F all geological questions, perliaps that of the Antiquity of Man 
is the most populär. Nor is it one on whicb geologists have 
been rasli or hasty in advancing new ideas ; quite the reverse : they 
have lagged behind the evidence. In the “ Principles of Geology,” 
one of the most instructive chapters is that in which the author treats 
of the progress of Geology. Therein Sir Charles Lyell has shown 
how the Science had been retarded for three hundred years by men’s 
reluctance to admit such a simple and obvious matter as the marine 
origin of stratified rocks, owing to a fixed idea that the world had 
come into being,a short time since in much the same state as it appears 
to-day. Yet the illustrious author of the “ Principles of Geology ” let 
pass for thirty years the evidence that Man was contemporaneous 
with the extinct Pleistocene mammalia. In 1833 the evidence on 
this point was nearly as complete as it is now ; but it was practically 
neglected because it did not square with preconceived ideas. In fact, 
it was not accepted tili Lyell himself, reviewing the facts in his 
usual masterly manner, summed up judicially in favour of the new 
views in his first edition of the “Antiquity of Man.” Now, to com- 
pare great things with small, a like reluctance to admit new evidence 
on the subject is widespread. Tlien the prejudice was that man was 
modern, that he never saw old-world mammals any more than 
Silurian forms of life ; now, admitting perforce his co-existence with
