[_i_] sometimes doth become a _Consonant_, but then is pronounced only
more swiftly, so as together with the following _Vowel_, it can make a
_Diphthong_; but [_i_] is formed after the same manner almost,
as [_e_] except that the _Teeth_ are for the most part, more stricken,
and the _Tongue_ put close to the _Teeth_, the passage of the _Voice_
is rendred more strait, whence a more smart Sound also breaks forth,
which notwithstanding, can sometimes be hardly distinguished from
[_e_] [_y_,] also is [_i_] pronounced longer then usually, or [_i_]
doubled. _o. u. w._ are _Labial Vowels_, that is, such as are formed
by a different positure of the _Lips_; also [_o._] and [_u._] are
different from one another, just as much as [_e._] and [_i_]: But
[_w._] is to [_u._] just as _j._ is to [_i._] for indeed _a. u. w._
are formed, when the _Teeth_ and _Tongue_ keep the same posture; but
the _Lips_ are more or less contracted, even as the _Teeth_ are in
[_e._] and [_i._] and so when they are less stricken, [_o._] is
produced, but when a little more [_u._] or [_w._]; but we ought
carefully to beware, whilst [_o._] or [_u._] are pronounced, least the
_Teeth_ should be seen; for else a certain kind of a soft _e._ will be
mingled; and instead of _ö._ or _ü._ there will be produced _o._ or
_u._ These Letters belong to the _French_, _au_ and _ou_, when
nevertheless they are nothing else but _Diphthongs_, also _oe._ of the
_Dutch_ is our _u._ but very improperly.

Mixt _Vowels_ are _ä. ö. ü._ These Characters are peculiar to our
Language, and were invented very ingeniously by our Ancients, though
our Moderns mostly know not the reason thereof. Each hath its simple
Character, because the Sound which they signifie, is only one, tho'
mixt; for _a._ _o._ and _u._ are so pronounced, that the passage of
the _Voice_, the _Tongue_ and _Teeth_ being conjoyned for to
pronounce, _e._ becomes Straiter, and so _e._ together with the said
