The specimen is made from a very hard grey rock,
apparently stained by limonite on patches of the surface. A thin section
cut from one edge shows a micaceous aggregate with a little iron ore.
The specific gravity of the specimen is 3.02. It has not been possible
to match this rock.
It is disappointing that so little can be said at present as to the
exact localities from which these implements originated. The need for
further research in this field is very obvious.
Reginald Smith noted in the B.M. Stone Age Guide (1926)
that greenstone and basalt axes are common in the Thames Valley, and it
is noteworthy that none of the present examples occurred more than three
miles from the south bank of that river.

MEDIEVAL DISCOVERIES AT CRAY HOUSE, BEXLEY
Digging undertaken in a very limited area of the garden of
Cray House, as recorded in Arch. Cant., LXXI, xliv,
revealed remains of several features of interest which it is the purpose
of this note to describe more fully.
The plan (Fig. 2) shows two fragments of walls composed of
broken roof-tiles1 set in clay mortar. These walls may have
1 The size of a complete
tile is estimated to have been 9½ in. by 6½ in. with a thickness of ½
in. They have tapering peg-holes and closely resemble the plain tiles
from Joyden’s Wood illustrated in Arch. Cant., LXXII, p. 28.
