This ClipArt gallery offers 5 illustrations of sign language phonetics, showing consonants that use the back of the mouth or throat. These illustrations were published by by Edmund Lyon of the Deaf-Mute Institution in 1891.

Consonants have a closed or narrowly expanded adjustment of the vocal organs, so that in their production some part of the throat or mouth obstructs, squeezes, or divides the breath. &hellip;in representing consonants the hand suggests a narrow adjustment of the organs, by having the prominent or accented fingers straightened and the second phalanx of the thumb close to the plane of the palm. <p> Non-Vocal Consonant positions have the voice phalanx of the thumb bent at right angles to the breath phalanx, or unaccented. Primary Consonant positions have only the first finger accented. Throat Consonant positions differ from those of the Back in having the index and center fingers separated.

Shut Consonant positions do not have any of the fingers accented. Throat Consonant positions differ from those of the Back in having the index and center fingers separated.

Consonants have a closed or narrowly expanded adjustment of the vocal organs, so that in their production some part of the throat or mouth obstructs, squeezes, or divides the breath. &hellip;in representing consonants the hand suggests a narrow adjustment of the organs, by having the prominent or accented fingers straightened and the second phalanx of the thumb close to the plane of the palm. From the Vocalized Throat primary consonant which represents guttural contraction, we may derive a very appropriate orinasal symbol by placing the breath phalanx of the thumb in the position for nasality. This symbol acts retrospectively, so in representing an orinasal we represent the vowel in the usual way and immediately follow it with the orinasal symbol.

Consonants have a closed or narrowly expanded adjustment of the vocal organs, so that in their production some part of the throat or mouth obstructs, squeezes, or divides the breath. &hellip;in representing consonants the hand suggests a narrow adjustment of the organs, by having the prominent or accented fingers straightened and the second phalanx of the thumb close to the plane of the palm. <p> Vocalized Consonant positions have the voice phalanx of the thumb accented; that is, brought in line with the breath phalanx; this constitutes the only difference between the Vocalized and analogous Non-Vocal Consonant positions. Primary Consonant positions have only the first finger accented. Throat Consonant positions differ from those of the Back in having the index and center fingers separated.
