No. 1 and 2 are not laid open in the great sand pits, but are seen in a chalk pit adjoining to the eastern extremity of the sand pit. The following section at Loam Pit Hill, near Lewisham, about three miles south-west of Woolwich, presents analogies that identify many strata in the two sections, as from the chalk upwards to No. 8; in each inclusively the principal difference consists in the presence of fewer or more pebbles, in beds of sand evidently contemporaneous.
