Note 40 — Chapter I

See, especially, the details of the conference held at Salamanca (the great seat of learning in Spain), given in the fourth chapter of Washington Irving's "Columbus." One of the objections advanced was, that, admitting the earth to be spherical, and should a ship succeed in reaching in this way the extremity of India, she could never get back again; for the rotundity of the globe would present a kind of mountain, up which it would be impossible for her to sail with the most favorable wind.—Hist. del Almirante, cap. ii.; Hist. de Chiapa por Remesel, lib. ii., cap. 27.
