It hath been too much the humour of late, for men rather to adventure on the Forreign crazy stilts of other mens inventions, then securely walk on the ground-work of their own home-spun fancies. What I here present ye with, is an original in your own Mother-tongue; and yet I may not improperly call it a Translation, drawn from the Black Copy of mens wicked actions; such who spared the Devil the pains of courting them, by listing themselves Volunteers to serve under his Hellish Banners; with some whereof I have heretofore been unhappily acquainted, and am not ashamed to confess that I have been somewhat soiled by their vitious practices, but now I hope cleansed in a great measure from those impurities. Every man hath his peculiar guilt, proper to his constitution and age: and most have had (or will have) their exorbitant exiliencies, erronious excursions, which are least dangerous when attended by Youthfulness. This good use I hope the Reader will make with me of those follies, that are so generally and too frequently committed every where, by declining the commission of them (if not for the love of virtue, yet to avoid the dismal effects of the most dangerous consequences that continually accompany them.) And how shall any be able to do this, unless they make an introspection into Vice? which they may do with little danger; for it is possible to injoy the Theorick, without making use of the Practick. * * * * * To save my Country-men the vast expence and charge of such experimental Observations, I have here given an accompt of my readings, not in Books, but Men; which should have been buried in silence, (fearing lest its Title might reflect on my Name and Reputation) had not a publick good interceded for its publication, far beyond any private interest or respect. When I undertook this Subject, I was destitute of all those Tools (Books, I mean) which divers pretended Artists make use of to form some Ill-contrived design. By which ye may understand, that as necessity forced me, so a generous resolution commanded me to scorn a _Lituanian_ humour or Custom, to admit of _Adjutores tori_, helpers in a Marriage-bed, there to engender little better than a spurious issue. It is a legitimate off-spring, I’ll assure yee, begot by one singly and soly, and a person that dares in spight of canker’d Malice subscribe himself A well-willer to his Countries welfare, _Richard Head_.
