The letter i is an indefinite line, representing man in his primitive state of innocence, as it does still his body, as a line, without its extension, and his head and senses by its dot; and in a secondary sense are expressed by this line and dot, length or heighth towards the sun, the sun-beams, fire, heat, and other qualities both spiritual and animal, as still flowing upon man, and other things as relative to him, and originally perhaps centering in himself, and since his fall only relatively. But though man and nature have been impaired by original sin, they still seem to be invested with certain springs, energies, or returns of those ilations and qualities, as, thinking, willing, voice articulate, powers generative and growth; whereby the human species may be extended, and acquire so much knowledge and virtue, as, with the blessing of Providence, to be capable of being reinstated. The chief of which springs is expressed by the letter u, a compound of two i’s signifying man’s compound of male and female, and spirit and matter, with a c at their bottom, springing them upwards; by y as to the generative and vegetative parts, which also is expressive of woods and other growth; it being a compound of i j, and half of the spring c, as not being expressive of the spirit of man. The i also expresses man as an upright line placed in the centre of all worldly beings and substances, to whom they bear a relation, as shall be shewn under adverbs. The u vowel seems to derive its figure from the human face, the seat of the voice, and the heart, and the feminine or consonant v from the vagina, if it be an original letter, but, from its sound, it seems to supply the place of the digamma. The y or Υ resembles trees, plants and vegetables, and the j consonant is the half of it, and sometimes made use of instead of g, to express some of the generative parts and qualities. These vowels have each two sounds, the high and low, long and short, or grave and acute, viz. i, as in, _in_, _high_, or _i_, go thou; the u vowel, as, in, _unction_, _united_; and the y as the u in unction and y in hyssop; but the w has only one long sound, as in _woman_, _womb_, _wood_, and it is mostly applicable to spirituals, man, and things belonging to him; the wh has the gutteral sound of the Welsh ch, or the Greek χ as in _where_, _why_; the j consonant has the sound of g in _generation_; and the v consonant that of the soft flowing f of the Welsh, or as in _verb_, _vice_; thus supplying the softer sound and meaning of the digamma.
