330 Notice and Review of the Reliquiae Biluvianae. 
Geologists, in view of this subject, have made ita ques- 
tion, whether all rounded pebbles and bowlders, except 
those abraded and worn by rivers and other causes, now 
in action, were detached from the parent rock, and brought 
into their present shapes, by the waters of the deluge. 
We believe all will agree, that all these pebbles and bowl- 
ders, lying above the regular strata, were moved, and 
course in some measure worn, by that catastrophe: and we 
think it almost equally evident, that all the abrasion they 
present, cannot be imputed tothatevent. This is obvious- 
ly the opinion of Mr. Buckland. In describing the dilu- 
vial detritus in the vicinity of London, he says, “ The 
quartzose pebbles which I have been tracing without in- 
terruption from Birmingham to London, had, as 1 have be- 
ore mentioned, received their roundness before they were 
imbedded in the red spnsions formation ; their form can- 
the hard quartzose pebbles we are considering”? Again, 
he says, “ Similar varieties of gravel, the one angular, the 
other completely rolled, and derivative from the pe 
beds of the plastic clay "formation, occur in the valley of 
the Thames near London. These rounded pebbles, like 
those from Warwickshire, had apparently received their 
attrition from the long continued action of violently agita- 
ted waters, during more early revolutions that have a 
our planet; whilst the imperfectly rolled fragments are 
referable to the diluvial waters, which drifted them omy
