NOTES UPON PALAEOLITHIC IMPLEMENTS
FROM WANSTEAD PARK.
By CHAS. H. BUTCHER.
[Read 27th March, 1915.]
HAVING in my collection two characteristic Palaeolithic im-
plements from the Middle Terrace Gravels at Wanstead
Park, Essex, I here propose to give some description of them
and the drifts or gravels from which they were obtained.
The implements from the Middle Terrace Gravels which
occur at Wanstead Park are principally worked flakes, well
exhibiting the dexterity and neatness attained in the art of
flaking by Palaeolithic Man at this epoch of his reign in Britain.
They are all more or less deeply patinated (orange, olive and
yellow), and in many cases considerably abraded. As far as
I am acquainted with them, none bear any large portions of the
original crust of the flint, but although with this exception, a
fair number closely resemble the types of the early and mid-
Chellean specimens.
The oldest class of the implements of the Wanstead District,
deeply ochreous, rude in make and sometimes greatly abraded,
are found only in the deepest pits from 12 to 40 feet down in
coarse gravel resting on the London Clay; while the lustrous'
patinated and slightly abraded specimens of medium age are
usually found in gravel at the 12ft. level.
The relation of the Middle Terrace Gravels to the other im-
