NOTES UPON PALAEOLITHIC IMPLEMENTS 
FROM WANSTEAD PARK. 
By CHAS. H. BUTCHER.

H AVING in my collection two characteristic Palseolithic 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.
