Bayle de refractione, s.d.
A page on the apparent position of planets, in light of Descartes. "Bayle" could conceivably refer to Pierre Bayle (1647-1706), who critiqued Cartesianism once, early in his career, but Peter Bayle was not strictly known as a mathematician or an astronomer.
Excerpta et notanda in Kepleri ... ad vitellionem, c1693
A discussion, probably inspired by Sir Isaac Newton, of whether it was Willebrord Snell or Voss who discovered a law of refraction first, from which Rene Descartes arguably derived his version at last.
