The letters r, ϱ, ρ, Ρ, R, represent animals and their parts, and their mouths as the place of sound; S being added to P, as a sound, forms R, the sound as well as part of an animal; and they are all to be sounded as in _viper_, except where they happen to be radical letters, and then with an aspirate h as in _rhyme_. The S, σ, Z, are also letters of sound, but express no part of man, and are rather the shape of some animal of the serpentine kind, the waving of the breath or water, &c. They have two sounds, the hard and soft, as in _loss_, _zone_. This explanation of letters, together with what has been given already in my former treatises, and shall be added amongst the particles, will, it is to be hoped, be deemed satisfactory, as to the sense and origin of letters, and the sacred characters; notwithstanding the pretensions lately set up for those of irregular lines, curves, and windings, which can express but few things, and the remarks of another ingenious gentleman, as to the non-entity or insignificancy of the Hieroglyfics; his enquiry having been confined to the vulgar sorts, or the paintings or engravings of animals, &c. when it now appears the Hieroglyfics consisted only of those few sacred or _secret_ characters. The hints and specimens here given of the method of combining the hieroglyfic figures, being as compleat as the press will admit of; and a process thereof, thro’ the whole of the English language, considering the corrupt state of languages, tho’ the English is as capable of an hieroglyfic combination as any, requiring much loss of time, trouble, and expence, and perhaps the aid of a Hunter and a Hill, and some other reasons occurring, the author hopes he shall be excused for proceeding no further at the present, in the combination of characters. Of Particles and Syllables. A Particle is a simple articulate sound and sign of one or two characters or letters; but a syllable sometimes by the cutting off of vowels, becomes a combination of more letters, which is yet commonly pronounced as a simple articulate sound; there being a natural relation and agreement betwixt the signs and sounds of letters, and ideas and things. Particles and syllables were originally framed according to their hieroglyfic shape, the natural sounds of ideas and things, and the sense and value of letters, as has been already explained; and therein the quantity of the action of sound was measured and proportioned to the motion, action, or energy of the thing to be expressed, as the high, loud, acute, or short accent, for an active or energic particle, and the low, grave, and long, for a passive, substantive, or a negative one.
