Mr. Webster appears to consider the Bagshot sand, 

 which extends over a considerable tract of country in 

 Surrey, and the blocks of granular quartz, named gray 

 weathers, met with in Berkshire and Wiltshire, as mem- 

 bers of this formation, and somewhat allied to the sand 

 and sandstone of the upper marine formation in the Paris 

 basin.
