A Comparative study of the whole of the evidence concerning the Palæozoic floor beneath the South-East of England and the manner in which the various members of the Mesozoics are disposed upon it has led the present writer to conclude that the area, originally defined by Professor P. F. Kendall, over which the effects of the operation of a “posthumous” Charnian axis may be discerned, can be greatly extended, more particularly to the eastward. The evidence, indeed, strongly suggests the presence of a second Charnian axis beneath Suffolk, proceeding thence south-eastward to North France.
