IV.—On the Constituents of the Sands and Loams of the Plateau Gravel occurring in the Pit Sections near Ash, Sevenoaks

Extract

I am indebted to the Rev. Ashington Bullen, B.A. (London), F.G.S., for eight samples of sands and loams from the Plateau Gravel of Kent, which he has placed in my hands for examination with the microscope. They were carefully collected by Mr. B. Harrison, of Ightham; and for convenience they are here lettered A–H.
