The pebbles of which the Bure 
valley beils are composed are, at 
Hellesdon and elsewhere, water- 
worn and rounded, but the imple- 
ment shows no sign of wear, as 
it certainly would have done had 
it been imbedded in a deposit of 
marine gravel, and finally, the 
pebbles arc of a dark red colour, 
being deeply stained with oxide 
of iron, while the implement is 
of ii grey colour, and shows very 
slight signs of being stained at all. 
It may be thought I have 
taken unnecessary pains to slay 
the slain, but it is worth taking 
some amount of trouble to show 
that there is no evidence what- 
ever for this supposed discovery. 
Some time ago, it was asserted 
on no better evidence than that 
of the present case, that TeUtna 
bait him had been found in the 
Norwich Crag, and it took us 
years, and cost us no end of 
labour to persuade geologists that 
such could not have been the 
case. It was only at last by the 
k merest accident that we were 
able to discover how the mistake 
originally arose.
