It is likely that there should be no thorow passage by the Northeast, whereby to goe round about the world, because all Seas (as aforesayd) are maintained by the abundance of water, waxing more shallow and shelffie towards the ende, as we find it doeth by experience in Mare Glaciali, towards the East, which breedeth small hope of any great continuance of that sea, to be nauigable towards the East, sufficient to saile thereby round about the world.

[Sidenote:  Quicquid naturali loco priuatur, quam citisime corrumpitur.] [Sidenote:  Qualis causa, talis effectus.] 2 Also, it standeth scarcely with reason, that the Indians dwelling vnder Torrida Zone, could endure the iniurie of the cold ayre, about the Septentrional latitude of 80. degrees, vnder which eleuation the passage by the Northeast cannot bee (as the often experience had of all the South parts of it sheweth) seeing that some of the inhabiants of this cold climate (whose Summer is to them an extreme Winter) haue bene stroken to death with the cold damps of the aire about 72 degrees, by an accidental mishap, and yet the aire in such like Eleuation is alwaies cold, and too cold for such as the Indians are.

3 Furthermore, the piercing cold of the grosse thicke aire so neere the Pole wil so stiffen and furre the sailes and ship tackling, that no mariner can either hoise or strike them (as our experience farre neerer the South, then this passage is presupposed to be, hath taught vs) without the vse whereof no voiage can be performed.

4 Also the aire is so darkened with continuall mists and fogs so neere the Pole, that no man can well see, either to guide his ship, or direct his course.

5 Also the compasse at such eleuation doth very suddenly vary, which things must of force haue bene their destructions, although they had bene men of much more skill then the Indians are.

[Sidenote:  Similium similis est ratio.] 6 Moreouer, all baies, gulfes, and riuers doe receiue their increase vpon the flood, sensibly to be discerned on the one side of the shore or the other, as many waies as they be open to any main sea, as Mare Mediterraneum, Mare Rubrum, Sinus Persicus, Sinus Bodicus, Thamesis, and all other knowen hauens or riuers in any part of the world, and each of them opening but on one part to the maine sea, doe likewise receiue their increase vpon the flood the same way, and none other, which Mare Glaciale doeth, onely by the West, as M. Ienkinson affirmed vnto me:  and therefore it followeth that this Northeast sea, receiuing increase but onely from the West, cannot possibly open to the maine Ocean by the East.

7 Moreouer, the farther you passe into any sea towards the end of it, on that part which is shut vp from the maine sea (as in all those aboue mentioned) the lesse and lesse the tides rise and fall.  The like whereof also happeneth in Mare Glaciale, which proueth but small continuance of that sea toward the East.
