Abstract
DR. JOHNSTON-LAVIS'S letter is indeed welcome; it confirms my own impression that English geologists have neglected concretionary processes. During my fifteen years of observation of the Fulwell beds no one ever suggested osmosis to me before Prof. S. Leduc. Even the authorities of the British Museum, South Kensington, whilst accepting a large number of my best specimens—some of them I cannot replace—have since repeatedly refused to give them the benefit of a modern classification, because none could be recognised.
