David, thanks for the links to Fullton's orrery! It's a remarkable piece of clockwork. It looks like it's fully up to date for its era (1830s), as it includes the "new" discoveries of Uranus, several asteroids, and the moons of the outer planets.

Neptune wasn't discovered until the 1840s, but you can imagine Fullton's frustration if he thought he'd completed his masterpiece, only to learn that yet another new asteroid, moon or planet had been discovered! Rather like Blackadder's mischievous coining of "new" words like "contrafibularity" when Dr. Johnson announces that he has finally completed his Dictionary of the English language!
