Lunaticks

However, perhaps the whole ethos of the Lunaticks can be summed up by a quote from a letter Darwin wrote to Boulton, apologizing for having to miss a meeting: "Lord, what invention, what wit, what rhetoric, metaphysical, mechanical, and pyrotechnical, will be on the wing, bandied like a shuttlecock from one to another of your troup of philosophers."

--Erasumus Darwin, physician, grandfather to Charles Darwin, founder of the Lunar Society of Birmingham aka the Lunaticks. They met every Sunday closest to the full moon for dinner and discussion.
