In the 1587 edition of Ortelius is a map entitled "Typus Orbis Terrarum," in which New Guinea is made an island, with the words "Nova Guinea quæ an sit insula aut pars continentis Australis incertum." On the Terra Australis, here brought up far more to the north than elsewhere, and separated from New Guinea only by a strait, are the words, "Hanc continentem Australem nonnulli Magellanicam regionem ab ejus inventore nuncupant." While this sentence shows how indefinite was the idea of the extent of Australia towards the south, we think that the entire delineation, which brings the great Terra Australis so far northward in this longitude into connexion with New Guinea, goes far to show that Australia had really been discovered.
In various editions of Mercator occur copies of a map entitled, "Orbis Terræ Compendiosa descriptio quam ex magna universali Gerardi Mercatoris Rumoldus Mercator fieri curabat aº 1587," in which similar indications are given to those in the map of Ortelius just described.
In the map of Peter Plancius, given in the English edition of the voyages of Linschoten, 1598, similar indications of Australia occur, but leaving the question of the insular character of New Guinea doubtful.
In the Speculum Orbis of C. de Judæis, Antwerp, 1592, is a map entitled "Brasilia et Peruvia," on which occurs, "Chæsdia seu Australis Terra quam
