On the other hand, the green-sand and chalk, as they ap- 
proach the central axis of the Weald, are not found to contain 
littoral shells, or any wreck of the fresh-water strata, such as

wasting cliffs. Had any such signs been discovered, we might 
ave been inclined, to suppose the geography of the region to 
ave once borne some resemblance to that exhibited in the dia- 
gram No. 77.
