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.

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
