ERRATA.
Courteous Reader,
IN a Work of this Nature it is impossible to escape Mistakes, the which Man-kind could never totally evade since the first lapse of his Great-grandfather Adam. I hope I shall obtain your pardon therefore, though this present Tract hath some few Typographical Errors, which yet are not many, nor considerable, though the Author were far remote from the Press all the while. I have here given thee notice of as many as I could here readily espy; If thou findest any other, I desire thy favourable Censure, and that thou wouldest correct these in manner following.
