Extract

It is now about forty years since the completion of the late Sir Aubrey Strahan's Geological Survey Memoir on the Isle of Purbeck and Weymouth, published in 1898. All those who, like the present writer, have known the Dorset coast from boyhood and have carried Strahan's maps and memoir over most of the ground many times cannot have failed to learn from them lessons of incalculable value. They will have come to regard the memoir as a model of scientific method and of lucid presentation, a classic not to be questioned save in matters of palaeontology, now necessarily out of date.

page 61 note 1 Strahan's coast-sections stop short at Handfast Point and so do not show this increased dip at the base of the Eocene.

page 71 note 1 Dines and Edmunds (1927) spoke of the “ close parallel with the Dorset overthrusts described by Strahan ”; but at the time they wrote the current interpretation of the Dorset faults by Strahan gave no grounds for drawing any parallel, which now for the first time becomes possible. On Strahan's view the force must have come from the opposite direction, as described above.
