Fossil Plants VOLUME - I

In acceding to Mr Shipley's request to write a book on Fossil Plants for the Cambridge Natural History Series, I am well aware that I undertaken a work which was considered too serious a task by one who has been called a "founder of modern Palaeobotany." I owe more than I am able to express to the friendship and guidance of the late Professor Williamson; and that I have attempted a work to which he consistently refuse to commit himself, requires a world of explanation.
