Abstract only. The chief facts are the alternation of peats of various 

 quality with sandy chalk or peaty calcareous beds ; the erosion of the 

 peat-surfaces and subsequent tilling up with reasserted chalk ; and the 

 existence of faults affecting part of these deposits. G. A. L.

Concludes that the upper marine deposits above the peat are very 

 recent, and later than the Roman conquest, that at the time of the 

 Roman invasion this region consisted of peaty marshes, and that the 

 formation of all the deposits of peat is earlier than the Roman 

 conquest. G. A. L.
