* If this sand belongs to the Reading Beds (and I know of no such sand in the 
Drift here), there must be a small outlier, or a large pipe, of the Reading Beds, 
making, however, no feature at the surface, and therefore not suspected. 
t It is hard to make out these sandy and silty beds, hut from the occurrence 
of shells one is led to infer that they belong to the hasement-hed of the London 
Clay.
