84 GEOLOGY OF THE ISLE OF WIGHT. 



At Esher the clayey district of the Bagshot 

 sands prevails and overlies the London clay, which 

 in our further progress is generally concealed by 

 the sands of this subdivision of the eocene strata. 

 At Goldsworth-hill, four miles north of Guild- 

 ford, a deep section of the Bagshot sands is ex- 

 posed, consisting of greenish and yellowish sands, 

 in which fossil teeth and other remains of several 

 kinds of fishes (principally of the Shark family), 

 and casts of shells, have been discovered. The most 

 interesting fossil obtained is a large tooth of a 

 Saw-fish, which, at that time, was the only known 

 instance of the genus Pristis in the English strata ; 

 but subsequently, examples of the teeth have been 

 found in the clay of Bracklesham, in Sussex. The 

 other teeth are referable to three kinds of car- 

 tilaginous fishes, and with them were associated 

 teeth and palatal bones of Bays, and vertebrae of 

 osseous fishes, of species common in the clay of 

 Sheppey; also a portion of the carapace or buckler 

 of a freshwater turtle.'* 



At Weybridge the banks show an example of 

 false stratification, as it is termed, of white and 

 fawn-coloured sands, with the usual capping of 

 gravel and clay. At Woking Common the Bag-
