Correction to account in Geological Survey Memoirs, vol.

Level of rails about 80 feet above Ordnance Datum.
From a letter from J. Darby to the Rev. O. Fisher, 1868.
["If, as is possible, the bore-hole was dry, the London
Clay might come up as what is here called 'dove-coloured
sand,' and the water might be got, as in other wells near,
from a bed in the London Clay."—Note from Mr. W. H.
Dalton.]
An account of a well at Brentwood came to hand too late
for insertion, and it will therefore form the starting-point of
another collection.
