Lot Essay
Two tracts dealing with the phenomenon of spontaneous luminescence and phosphorence. Having witnessed the wandering showman, J.D. Krafft, demonstrate his kalte Feuer to Charles II, Boyle "was led to isolate phosphorus which had been independently isolated by the German chemist K. Brand (or Brandt) in 1667. Boyle then published his two celebrated tracts, the first on Aerial Noticula as he called it -- the 'stuff' that gives fireflies their glow -- and Icy Noticula, which he believed to be phosphorus itself" (Fulton).
