The plastic Brickearth closely resembles London Clay, from
which it was probably derived. Bones, obtained from the
Corbicula sands, have been identified as :
Elephas sp., Metacarpal III or IV.
Equus sp., Left metatarsal.
Bos or Bison sp., Left humerus (distal end), left femora
(one whole specimen and a proximal
end), thoracic vertebra, cervical verte-
bra, right scapula and scapula fragment.

COMPARISON WITH DEPOSITS OF THE CLASSIC SITES.
The section provides an interesting comparison with the
High Road ( =Cauliflower, Sam's Green, Curtis' or Page's Pit)
and Uphall sites, whose successions may be summarized here.
Figure 1 indicates the position of these older sites, together
with the recent section.
