Nevertheless, to approve that there lieth a way to Cathay at the north-west from out of Europe, we have experience, namely of three brethren that went that journey, as Gemma Frisius recordeth, and left a name unto that strait, whereby now it is called Fretum Trium Fratrum. We do read again of a Portuguese that passed this strait, of whom Master Frobisher speaketh, that was imprisoned therefore many years in Lisbon, to verify the old Spanish proverb, "I suffer for doing well." Likewise, An. Urdaneta, a friar of Mexico, came out of Mare del Sur this way into Germany; his card, for he was a great discoverer, made by his own experience and travel in that voyage, hath been seen by gentlemen of good credit. Now if the observation and remembrance of things breedeth experience, and of experience proceedeth art, and the certain knowledge we have in all faculties, as the best philosophers that ever were do affirm truly the voyage of these aforesaid travellers that have gone out of Europe into Mare del Sur, and returned thence at the north-west, do most evidently conclude that way to be navigable, and that passage free; so much the more we are so to think, for that the first principle and chief ground in all geography, as Ptolemy saith, is the history of travel, that is, reports made by travellers skilful in geography and astronomy, of all such things in their journey as to geography do belong. It only remaineth, that we now answer to those arguments that seemed to make against this former conclusion.
