The other kind of _Consonants_ are explosive; which, _viz._ are discharged at one push, and as it were, in the twinkling of an Eye and are nothing else but _Breath_, which being got close together, either in the fore, middle, or hinder Region of the Mouth, is discharged on a suddain; and (_k_) is indeed formed in the hinder Region, when the hinder part of the _Tongue_ is moved to the _Roof_, that the _Breath_ cannot break forth, neither by the _Mouth_, nor by the _Nose_, but is suddenly let loose again: For thus the imprisoned _Breath_ breaks out, and by breaking out, maketh _k. c._ or _q._ which in _Germany_ are all the same Letter; in the middle Region are _d._ and t. formed, when, _viz._ the _Breath_, by help of the Tongues being moved to the _Teeth_, or _Roof_, and suddainly drawn back again, being more or less compressed, rusheth out by its own Springiness, and so _d._ or _t._ is made, which only differs, as _b._ and _p._ according to the more or less; in the outermost Region of the _Mouth_ are formed, (_b_) and (_p_) when, _viz._ the _Breath_ being compressed in the whole _Cavity of the Mouth_, they get out through the _Lips_ opened. Lastly; here follows those _Consonants_, which are compounded of _Hissing and Explosion_, such are (_x_) or _ks._ and (_z_) or _ts._ which only are the alone anomalous or irregular ones of the _German_ Language; for if I may speak what I think; we might well enough want these _Characters_; yet I disapprove not of the use of them, but only shew what might be more convenient, _viz._ that _Voice_ or _Breath_ which is simple, might be expressed also by a simple _Character_, and on the contrary, that a _Character_, which is simple and only one, would signifie but one only _Voice_ or _Breath:_ But if the commodious use of _Short-hand_ may be objected, I would perswade to express all possible Combinations, of _Vowels_, with _Semi-vowels_, and _Consonants_, by simple _Characters_. This is what I determined to say concerning the Letters, and their Formation; and seeing I am not willing to write a _Grammar_, what might yet further be said of them, I pass by; but what I have performed, I leave it to others to judge thereof, not so much to teach them, as by what is here presented to excite them, being desirous, as it becomes a young Man, to learn of them: I hope they will pardon my Errors, because of my Youth. Yet certain I am, had the ancient _Hebrews_, _Greeks_ and _Romans_, thus describ'd their Letters, there would have been no contention about the manner of Pronounciation. CHAP.
