page 277 note 1 Mr. David Forbes, F.R.S., pointed out, many years ago, that the Hard Chalk and Grey Chalk really contained an equal quantity of silica as the Upper Chalk with flints, but it had not segregated out into flints in the former as in the latter formation. An excellent account of the Chalk formation and of the Flints and their probable mode of origin will be found in the Geology of England and Wales by Woodward, Horace B., F.G.S.
