Appendix

Abstract

Well-sections to follow, for reference, after the section at Park Hill, Croydon : ante, p. 99. South to North sections,--from Croydon to Ware. At Mitcham Mr. Nightingale kept the following careful record of his well, and preserved a series of specimens, but I found the shells generally too much crushed by the auger to be determinable. Well-section, Nightingale's Factory, Mitcham*, 1850.
