Carboniferous limestone, and as near Gloucester as Hempstead, 
Felstone. 
In my collection I have numerous other foreign drift 
pebbles from various parts of the Cotteswolds, extending from 
Chipping Norton to Uley Bury, and I have been unable to 
identify the rocks from which some of these were derived. 
I cannot therefore help thinking that these two interesting 
pebbles must have come from the drift, although it is difficult 
to explain how the Oolitic matrix in which they are partly 
embedded, became attached to them. 
Since this Paper was read, I have, with Mr Smith, visited 
the quarry, which is now filled up; and when there, I saw 
Kirby, who assured me the pebble came out of the bottom, 
which was about ten feet below the surface, and was covered 
with the white stone. The quarry is near the junction of six 
roads, and within a few yards of the Half Way House Inn, and 
there are pit dwellings close to. 
On examination of the clay underneath the turf, I found 
it to correspond with the same I have met with in places all 
over the Cotteswolds, and in the large quarry at the other end 
of the Common there were fissures filled with it, many feet 
below the surface, like those in Woodchester Park, in the 
Boulder Clay, and which confirms my impression that the 
pebbles belong to the drift period. (See my Paper on the 
Gravel of the Severn, Avon, and Evenlode, and their extension 
over the Cotteswold Hills. Proceedings Cotteswold Club, vol. 
V, p. 108.)
