2 _Fretum_ a streight or narrow sea running betweene two lands.

3 _Sinus_ a Creeke, Gulfe, or Bay, when the sea runnes vp into
the bosome of the land by a narrow enterance but openeth it
broader when it is within; if it bee very litell it is called a
Hauen, _Portus_.

4 _Lacus_ a Lake, a little sea with in the land hauing riuers
running into it, or out of it, or both. If it hath neither it is
called _Stagnum_ a standing Poole, also _Palus_; a fenne.

5 _Fluvius_ a Riuer, which from the pleasantnesse is also called
_Amnis_; from the smalnesse of it _Rivus_.

Now concerning these parts diuers questions are moued; whether
there bee more Sea or Land? whether the sea would naturally
ouerflow the land, as it did in the first creation, were it not
withheld within his bankes by diuine power? whether the deepenes
of the Sea, doth exceede the height of the mountaines? whether
mountaines were before the flood? what is the hight of the
highest hilles? whether Iland, came since the flood? what is the
cause of the Ebbing and flowing of the Sea? what is the original
of springs and riuers? what manner of motion the running of the
riuers is? with such like, whereof some belong not so properly to
this science of Geography as to others. Wee speake onely a word
or two of the last, & so proceed. The question is whether the
motion of the riuers bee streight, or Circular. The doubts on
both sides will best appeare by a figure first drawne: wherein,
Let (_HMO_) be the Meridian of _Alexandria_ in _Ægipt_, or of the
