[_g_] or _ch._ is sharper than [_h_] which I teach thus, when I shew
to my Deaf Patients the posture of the _Tongue_ in a Looking-Glass,
and give them to feel the expiring _Breath_; it is so in like manner
with [_s_] and [_f_] insomuch, as nothing is more easie than they, and
which may most easily be learned by the fore-going Description.

I can teach a Deaf Man, (though he were blind) the _Explosive
Consonants_; for if I cause him to feel the _Breath_ discharged upon
him, he would necessarily pronounce one of the three; for I bid him to
look simply on my _Mouth_ and _Tongue_, and then having put his Hand
to my _Mouth_, I pronounce either [_k._] or [_b._] [_p._] or [_d._]
[_t._] and command him to do the like.

(_x._) and (_z._) are pronounced no otherwise than is (_ks._) or
(_gs._) (when (_g_) is an _Explosive Consonant_) and (_ts._) wherefore
I shall add nothing concerning them.

Deaf Persons are to be diligently accustomed to pronounce these
_Semi-vowels_, _n. ng. l. r._ also the following _Consonants_; _h. g.
k. t._ with some kind of opening the _Mouth_, else they may joyn them
sometimes with certain _Vowels_, not without a notable yawning, & a
discordant noise. Now in general, Winter-time is fitter almost for to
instruct the Deaf, because then they see the _Breath_ coming forth
from the _Mouth_, whilst Pronounciation is in doing.

When therefore I taught any Deaf Person to pronounce the Letters
hitherto enumerated, and that one by one, I taught him so to utter two
or three of the easiest, that there should be interstice between them;
as for example, _ab. am. da. fa. ef. &c._ so that they might be
