Abstract
As a small contribution to this theory, the Cornish beaches may furnish a quota. They are entirely composed of finely comminuted shells, with a small admixture of fragments of Bryozoa, spines of minute Echinoderms, and occasional mica flakes. Such sandy beaches occur in small bays, and if subjected to metamorphic action would form lenticular masses of limestone intercalated between the strata deposited above and below them. Hence such occurrences of limestone might well indicate such a littoral origin as is here displayed.
