IV on Variation, Pedro Medina in his Art de Navigar, Valladolid, 1545, contended that the magnetic needle always points to the true north; Stevenson, E. L. Early Spanish Cartography of the New World. (In: Proceedings of the American Antiquarian Society. Worcester, 1909.) Attention is called in this paper to certain errors in early Spanish maps, probably due to a failure to note properly the declination of the magnetic needle.
