Primaval Man in the Valley of the Lea.

I have not yet seen. A few chisel-ended implements occur. 
Eude choppers and somewhat large scraping tools are com¬ 
mon. All the artificially-chipped stones of this medium age 
are subabraded and lustrous. They were not made where 
now found, but 
have been carried 
by the drift for 
a short distance 
from the north, 
or from a higher 
terrace. A point¬ 
ed weapon and 
a chopper of me¬ 
dium Palaeolithic 
age are illustrated 
half real size at 
figs. 10 and 11 
(formerly Nos. 
588 and 482 in 
my collection, but 
now in the pos¬ 
session of Mr. 
John Evans). A 
scraper from the 
Thames Valley at 
Hanwell (No. 9 in 
collection) is il¬ 
lustrated half real 
size in fig. 12. 
The tools when 
seen in the un¬ 
disturbed gravel 
of the Lea are 
invariably flat Fig. —Chopping-tool, one half actual size. 
never upright, and the butt or heavy end is often towards the 
Thames and the point towards the northern position from 
whence they have been washed. It is rare to find implements 
in situ , although I have several times so found them.
