[Herne Bay and Reculver were first visited on June 26th, 1863. The following details of this excursion are taken from the report by George Dowker, the Director.] (Proc., Vol. i., pp. 339-345.)

On arrival at Herne Bay the party, about thirty in number, proceeded in conveyances to Reculver, passing on their way various sections shown near the bridge-crossings of the Herne Bay and Margate (L. C. & I).) Railway, then being constructed. On alighting at Reculver they first went to see the church and Roman camp. Descending from the churchyard they found the cliff composed entirely of Thanet Sand. At its base were tabular, concretionary blocks of indurated sandstone; these blocks generally rested upon a very fossiliferous deposit, shells of the genus Cyprina being often in great abundance. Passing along the shore towards Herne Bay, the Thanet Sand was seen to dip in a westerly direction till it disappeared at Bishopstone, the Woolwich Beds forming the lowest beds. Above the Woolwich Beds were the light-coloured sands with concretionary masses of red sand, containing much iron, and thin pebble beds towards their base, termed by Prestwich the basement bed of the London Clay.[1] But before reaching Bishopstone the London Clay proper had appeared above this light-coloured basement bed, and, the dip continuing westerly, towards Herne Bay the London Clay formed the entire cliff.

The Thanet Sands contain many fossils, but few species, Cyprina Morrisi being the most common. In the Woolwich Beds the most abundant genera are Corbula, Dentalium, Cucullæa, and Cyprina.
