d be called Je, and should have a different character
from the vowel i, with which it has an analogy, as thus _V_.

H. If the back part of the tongue be appressed to the pendulous
curtain of the palate and uvula; and air from behind be forced between
them; the sibilant letter H is produced.

Ch Spanish. If in the above situation of the tongue and palate a sound
be produced behind; and the sonorous air be forced between them; the
Ch Spanish is formed; which is a sonisibilant letter, the same as the
Ch Scotch in the words Bu_ch_anan and lo_ch_: it is also perhaps the
Welsh guttural expressed by their double L as in Lloyd, Lluellen; it
is a simple sound, and ought to have a single character as [TN: Looks
like an H on its side].

The sibilant and sonisibilant letters may be elongated in
pronunciation like the vowels; the sibilancy is probably occasioned by
the vibrations of the air being slower than those of the lowest
musical notes. I have preferred the word sonisibilants to the word
semivocal sibilants; as the sounds of these sonisibilants are formed
in different apertures of the mouth, and not in the larynx like the
vowels.

_Orisonant Liquids._

R. If the point of the tongue be appressed to the forepart of the
palate, as in forming the letters T, D, N, S, Z, and air be pushed
between them so as to produce continued sound, the letter R is formed.

L. If the retracted tongue be appressed to the middle of the palate,
as in forming the letters K, Ga, NG, Sh, J French, and air be pushed
over its edges so as to produce continued sound, the letter L is
formed.

The nasal letters m, n, and ng, are clear tremulous sounds like R and
L, and have all of them been called liquids by grammarians. Besides
the R and L, above described, there is another orisonant sound
produced by the lips in whistling; which is not used in this country
as a part of language, and has therefore obtained no character, but is
analogous to the R and L; it is also possible, that another orisonant
letter may be formed by the back part of the tongue and back part of
the palate, as in pronouncing H and Ch, which may perhaps be the Welch
Ll in Lloyd, Lluellin.

_Four pairs of Vowels._

A pronounced like au, as in the word call. If the aperture, made by
approximating the back part of the tongue to the uvula and pendulous
curtain of the palate, as in forming the sibilant letter H, and the
sonisibilant letter Ch Spanish, be enlarged just so much as t
