James Hutton – A Theory of the Earth with Proofs and Illustrations – 1795
WTF? Hutton was talking about upthrusting, but it is hard to tell from his description. Hutton's great work was "Theory of the Earth; or an Investigation of the Laws observable in the Composition, Dissolution, and Restoration of Land upon the Globe (1788)". He was never at a los for words, it seems.
Fortunately Hutton had a dedicated and less verbose assistant named John Playfair who re-wrote/translated Hutton's work after his death into something that everyone could read. Playfair's "Illustrations of the Huttonian Theory of the Earth (1802)" clarified Hutton's ideas and did not put everyone to sleep in the process (even the title was considerably shorter). Suddenly everyone said, "Oh, now I get it. What a clever fellow that Hutton was". Bless that John Playfair.
