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 to prevent sibilancy; and a continued sound produced by the larynx be modulated in passing through it; the letter A is formed, as in ball, wall, which is sounded like aw in the word awkward; and is the most usual sound of the letter A in foreign languages; and to distinguish it from the succeeding A might be called A micron; as the aperture of the fauces, where it is produced, is less than in the next A. A pronounced like ah, as in the word hazard. If the aperture of the fauces above described, between the back part of the tongue and the back part of the palate, be enlarged as much as convenient, and a continued sound, produced in the larynx, be modulated in passing through it; the letter A is formed, as in animal, army, and ought to have an appropriated character in our language, as thus [TN: Looks like an A on its head]. As this letter A is formed by a larger aperture than the former one, it may be called A mega. A pronounced as in the words cake, ale. If the retracted tongue by approximation to the middle part of the palate, as in forming the letters R, Ga, NG, Sh, J French, L, leaves an aperture just so large as to prevent sibilancy, and sonorous air from the larynx be modulated in passing through it; the letter A is produced, as pronounced in the words whale, sale, and ought to have an appropriated character in our language, as thus [TN: Looks like a handwritten 9]; this is expressed by the letter E in some modern languages, and might be termed E micron; as it is formed by a less aperture of the mouth than the succeeding E.
