IV.—On Roslyn or Roswell Hill Clay-pit, near Ely1
Published online by Cambridge University Press: 01 May 2009
Extract
Roslyn or Roswell Hill Clay-pit has long been a standing puzzle to Cambridge geologists. I have visited it several times, and have notes upon it made in 1853 and in 1856. I was there in November, 1866, having, by Professor Sedgwick's permission, the the assitance of Mr. H. Keeping.
