conglomerates, indurated sand-rock, and a fine sandstone, of 

 great compactness, called grit. At Hastings, sands and 

 clays, with interspersions of lignite, laminated shales, grits, 

 and sandstones, constitute a long range of high cliffs.* The 

 general resemblance of these strata to fluviatile sediments 

 is most striking ; the laminated structure of the clays and 

 shales, the constant intermixture of minute portions of 

 lignite, the absence of pebbles and shingle, and the alterna- 

 tions of mud and sand, are lithological characters constantly 

 observable in river deposits.
