The Greywacke

'A colourful and joyous romp through the not-so-sedate world of mid-nineteenth-century geology' - John Wright, author

'Engaging and persuasive ... Everyone interested in geology should know about Murchison, Sedgwick and Lapworth' - Richard Fortey, author

'This is history with its boots on ... Packed with vivid stories, The Greywacke brings to life an unlikely cast of characters who changed the way we view the world' - James A. Secord, author

'Whether trudging down Welsh ravines, scrambling in the Lake District, covering vast distances across rural Russia or hard going amid the crags of north-west Scotland, the writing puts us there, in the field, on the ground ... A great story well told' - Andrew Greig, author

'A joyful collision of science, history and nature writing, The Greywacke shines a light on the almost superhuman feats of endurance, the unglamorous physical realities, the many, many hours of patient labour that the science of geology is built upon. Following the work of three important nineteenth geologists as they attempt to unlock the secrets of the rocks and the mysteries of geological time, it uncovers a story of friendships, feuds, triumphs and breakdowns. I particularly enjoyed the chapter on Lapworth: a beautifully clear and engaging description of the mechanics of stratigraphic work and a wonderful portrait of a scientist who deserves to be better known' - Helen Gordon, author
