FOREST MARBLE : CHARTERHOUSE HINTON. 351 
FT. IK. 
"Buff sands with large concretionary 
masses or "doggers" of calcareous 
sandstone. Some of the beds are 
very fissile. Lenticular masses and 
Forest Marble -<( thin seams of loam occur here and 
there, in which some Foraminifera 
and an Ostracod were found* -24 6 
Sand and another layer of stone (not 
(_ worked) - - 8 or 10 
These beds are the " Hinton sand and sandstone" of William 
Smith, the name being employed by him about the year 1800, 
and being published in 1813 by the Rev. Joseph Townsend.f 
Lonsdale who has given a particular account of these beds, 
remarks that "Patches or small almond-shaped nodules of soft 
clay are often imbedded in the stone ; and on being removed, by 
exposure to the weather, the emptied cells give it a vesicular 
appearance. Organic remains are not universally disseminated 
through the grit, but in some localities they are sufficiently 
numerous to compose the principal part of the block or stratum 
and convert it into an impure shelly limestone.''^ 
At Ridge or Rudge near Westbury, in Wiltshire, a pit showed 
the following section :

("Water at base of pit.) 
The upper beds are somewhat tumbled and irregular. The 
sandy beds evidently represent the Hinton Sandstone, and some 
of the concretionary masses, as remarked by Lonsdale, assume the 
form of " pot-lids." 
East of Telisford, just above Vaggs Hill Farm, we find hard 
compact and rather gritty limestone, surmounted by clays, which 
underlie the Cornbrash. A quarry east of Farleigh showed the 
same succession, as follows :
