Mr, Buckland on the 
Considerations on the Evidences of a Recent Deluge , afforded by 
the Gravel Beds , and state of the Plains and Vallies of Warwick- 
shire , and the North of Oxfordshire ; and of the Valley of the 
Thames from Oxford downwards to London . 
The extent of the quartz rock of the Lower Lickey, with its 
attendant fragments of other formations which I have been describing, 
is altogether so very inconsiderable, that I should have scarcely 
deemed it worthy the attention I have paid to it, had it not derived 
much greater importance from the wide dispersion and vast 
abundance of its ruins. The quantity of wreck we find dispersed 
over immense tracts of country, under the form of completely 
rounded pebbles of granular quartz rock, exactly similar in substance 
to that of the Lower Lickey, warrants us in assuming that there 
has been an extensive destruction of the masses from which these 
pebbles were supplied. Hence it seems certain, that before these 
pebbles were reduced to their present state, the quartz rock extended 
very far beyond the limits it now occupies, possibly so far as to be 
uninterruptedly connected with the beds of similar formation in 
the Caer Caradoc Group, in Salop; this and the Lickey Ridge being 
but residuary fragments of a once continuous chain, of which the 
intermediate portions have been broken down, and after violent 
attrition accumulated in the form of beds of pebbles in the lower
