Extract

Six years ago, in a paper read before this Society, Dr. Herbert H. Thomas drew attention to the relative abundance of andahsite in the Plioeene deposits of Cornwall, East Anglia, and Kent, and also in various glacial and recent sands. When that paper was written, the only recorded occurrence of unaltered detrital andalusite in sedimentary rocks of greater age than the Pliocene was that in the Middle Chalk of Beer in Devonshire.
