General History of the Air (27 Apr)

“By the Air I commonly understand that thin, fluid, diaphanous, compressible and dilatable Body in which we breath, and wherein we move, which envelops the Earth on all sides to a great height above the highest Mountains; but yet is so different from the Aether [or Vacuum] in the intermundane or interplanetary Spaces, that it refracts the Rays of the Moon and other remoter Luminaries.” Robert Boyle, General History of the Air, 1692.
