Wilkins, John, A discovery of a new world : or a discourse tending to prove, that 'tis probable there may be another Habitable World in the Moon ; with a discourse concerning the Probability of a Passage thither; unto which is added, a discourse concerning a New Planet, tending to prove, that 'tis probable our earth is one of the Planets

So that the Orb of its an-

All which appearances, cannot ſo well be
