Who he was
A clergyman and geologist, Reader in Mineralogy and Geology at the University of Oxford. When Henry Duncan wrote to him about the Scottish footprints, he at first doubted they were footprints at all. The casts Duncan sent changed his mind.
Tortoises on pastry
He walked a crocodile over soft pie crust, then his own tortoises over pie crust, wet sand and soft clay. In December 1827 he wrote to Duncan that he had little or no doubt tortoises made the fossil tracks. He guessed ancient tortoises moved faster than his own "dull torpid prisoners".
The dough party
On January 19, 1828, he repeated the trial at the London home of the geologist Roderick Murchison, before a room of scientists. The tortoises would not move, even when he flicked their tails, because they had stuck fast in the dough. A young guest, John Murray, wrote that many who came to scoff went home more ready to believe.
