The Labials are expressed by two curved figures for the lips. The Linguals by the figure of a tongue, according to its various applications either of the Top or Root to the several parts of the palate or teeth. The tongue is divided to represent vibration in forming R, HR.

The Sonorous consonants, of each kind, are distinguished from the Mutes, by the addition of ( ˜ ) to represent the motion of the epiglottis, by which sound is made.

The Breathing consonants are represented by a line passing through the mouth in various positions, according to the emission of the breath, the line being placed above the palate in the nasal letters.

It will be found that in this alphabet, J, Q, and X, are omitted as being compound letters, K as being synonymous with C (hard), and H as being a simple aspirate.
