Prof. Morris remarked that though we have here the Thanet Sands 

 lying conformably on the Chalk, it is probable that we have lost some 

 hundreds of feet of chalk, either by denudation or by decomposition 

 after the deposit of the sands, and that the bed of green-coated flints 

 on the Chalk must have been formed by the quiet and slow removal 

 of part of the latter. W. W.
