It is not strictly required, when attending a meeting of the American Astronomical Society, to pose in front of the big AAS sign. However, I couldn't resist the opportunity. #aas247

Lord Byron, "Don Juan," Canto X [1823]
I haven't quite decided if this is the ideal epigraph for chapter 8. Too Byronic, do you think, or just Byronic enough?

Yesterday afternoon in the rooms of the Royal Society, at a joint session of the Royal and Astronomical Societies, the results obtained by British observers of the total eclipse of May 29 were discussed. [Times, November 7, 1919, page 12]
Oh, darn! This means I missed this year's "Revolution in Science" Day. (Headline in the Times of London from Nov. 7, 1919 about the same eclipse results.)

Why didn't geologists take Snider- Pelligrini seriously in 1858? Partly because of the lack of a known mechanism for plate techtonics. Partly because of his involvement in a wonky French plan to colonize Texas.
