The above remarks apply mainly to the circumambient 
deposits ; in inland hollows the debris would be accumu- 
lated when the cliffs were much higher, and though the 
latter to a great extent become denuded, the talus would 
remain, and even become augmented; so that somewhat 
massive conglomerates may occasionally occur at periods 
later than the Keuper. 
The “‘Dolomitic Conglomerate” is thus the most massive 
of all marginal accumulations presenting conglomeratic 
structure belonging to the Mesozoic era in the Mendip 
district, this circumambient accumulation being overlain

in places by deposits of somewhat analogous lithic 
structure, but not nearly so massive. It is at the close of 
Keuper times that the description of the past geography 
of the Mendip area is first attempted. The conclusions 
are, of necessity, mainly theoretical. In such a district 
as the Mendips they would be based upon the consideration
