Great Britain hare they been found to the north-west of a line drawn from 
the Severn to 'the Wash in Norfolk— a distance of two hundred miles, and 
in the direct line of the Lias escarpment ; ” and he further adds the sugges- 
tive fact, “ It is worthy of remark that the line of demarcation between the 
Drift-implement districts and those destitute of them, nearly corresponds 
with the line which divides the boulder-clay districts, from those destitute of 
boulder-clay. {Jour, of Anthrop. Inst., Jan. 1872, p. 284.) 
On the other hand, far from the chalh, on the ancient rocks of Norway and 
Sweden, there are no Palaeolithic tools ; the Museum of “ Copenhagen 
contains more than 10,000 polished stone axes and other implements of 
stone, and that of Stockholm not fewer than 15,000”; “but the Palaeolithic 
types are absolutely unknown there.”* The same kind of evidence is yet 
more conclusively derived from the ancient valley gravels of Cornwall ; 
these stanniferous gravel-beds have been thoroughly explored through at 
least a period of 2,000 years, in search of the “stream- tin” which they 
contain, and yet not one “tool” of the true Drift type has ever been 
found in them. Is it conceivable that Palaeolithic man selected only as his 
dwelling-place the dry and thirsty lands of the chalk-wolds, where no water 
is ; that he so loved the bare and barren sands which now constitute the 
rabbit warrens of West Norfolk, as to leave his weapons there by thousands ; 
and that he abhorred to dwell in the rich valleys of the new red sandstone, 
or in the “golden valleys” at the foot of the Oolite escarpment, where no 
such relics of his presence can now be found ; or is it not more rational to 
infer that this close relationship of the geographical distribution of the 
“ implements ” to geological structure is the result alone of natural causes ? 
3. No relics of man are found in the Drift with the so-called Implements . — 
Wherever man has been known to have existed, even in his most degraded 
state, there the evidences of his former presence are multiform. The people 
of the ancient lake-dwellings of Switzerland, in addition to their stone im- 
plements, left behind them the relics of their pottery, their food, their 
raiment, their ornaments, their habitations, and indications of their habits 
and pursuits ; but when w r e turn from these abundant evidences of man’s 
presence, to the consideration of the evidence presented by the Drift beds, 
we find roughly-chipped flints, and these alone ; not a bone of man’s frame, 
not a shred of his clothing, not a fragment of his pottery, not a trace of his 
habitation, or any indication of his works or pursuits : nothing but roughly- 
chipped flints dignified by the name of axes, and unlike in form and type 
any implements ever known to have been used by man ; and this form passes 
by such insensible gradations into the other forms of the rough angular gravel 
in which they are embedded, that the assumed evidence of design becomes 
obscured and obliterated. In the whole history of inductive science it 
would be difficult again to find a case in which so large a superstructure was 
attempted to be built on so slender a foundation.
