maintain itself, for the tides and courses of the sea are maintained
by their interchangeable motions, as fresh rivers are by springs, by
ebbing and flowing, by rarefaction and condensation.

So that it resteth not possible (so far as my simple reason can
comprehend) that this perpetual current can by any means be
maintained, but only by a continual reaccess of the same water,
which passeth through the strait, and is brought about thither again
by such circular motion as aforesaid, and the certain falling
thereof by this strait into Mare del Sur is proved by the testimony
and experience of Barnarde de la Torre, who was sent from P. de la
Natividad to the Moluccas, 1542, by commandment of Anthony Mendoza,
then Viceroy of Nova Hispania, which Barnarde sailed 750 leagues on
the north side of the Equator, and there met with a current which
came from the north-east, the which drove him back again to Tidore.

Wherefore this current being proved to come from the Cape of Good
Hope to the strait of Magellan, and wanting sufficient entrance
there, is by the necessity of Nature's force brought to Terra de
Labrador, where Jacques Cartier met the same, and thence certainly
known not to strike over upon Iceland, Lapland, etc., and found by
Barnarde de la Torre, in Mare del Sur, on the backside of America,
therefore this current, having none other passage, must of necessity
fall out through this strait into Mare del Sur, and so trending by
the Moluccas, China, and the Cape of Good Hope, maintaineth itself
by circular motion, which is all one in Nature with motus ab oriente
in occidentem.

So that it seemeth we have now more occasion to doubt of our return
than whether there be a passage that way, yea or no: which doubt
