rpHE main physical features of the county are the Chalk uplands 

 X of the south-eastern and southern part, the curious plateau 

 on the west, the Cam Valley between them, and the fenland of 

 the north. 



Of Jurassic rocks, the Oxford Clay is not well exposed save near 

 Whittlesea. The Corallian rocks are of considerable interest. Two 

 types occur — the Ampthill Clay facies of the western outcrop and 

 the Calcareous facies of the Upware Inlier. The Elsworth rock 

 forms the base of the deposits of each of these types, and its 

 relationship to the members of the Calcareous facies is a subject 

 still under discussion. The Upper and Lower Kimeridge Clay are 

 found at Ely and in the neighbourhood of that city. 



Of Ci"etaceous rocks the Lower Greensaud is well seen near 

 Gamlingay. The old phosphate workings of Wicken are now closed. 

 The Gault is seen in many exposures. Most of the sections exhibit 

 Lower Gault, but Mr. Fearnsides has recently detected the Upper 

 Gault in the Barnwell brick-pit. The basal member of the Chalk,
