The following is taken from a MS. by the late Mr. John Brown, F.G.S., of Stanway, Essex, and given by him to ProfessorHenslow, who gave it to me. The actual measurements are not mentioned, but I believe the scale to be about an eighth of an inch to a foot. It is valuable as having evidently been made when the beds were better seen than usual. Moreover, the constant waste of the cliff alters the section continually.
