_Thus far this Learned =Philosopher=: To which I shall only add this, That if when he wrote those Essays, =Chymists= were able to contribute so much to the Necessities and Conveniences of Mankind, when =Chymistry= was but young in =England=, and but few Chymists who were accurate in their Operations, and perhaps, fewer who had any competency of Learning, or so much as lightly Tincted with the =Hermetick Philosophy=; if, I say, that it discovered so great a light when it had but newly ascended our Horizon, and was, as I may say, but in its Infancy, what assistance may now be had from it, when (notwithstanding all the Obstacles, and unkind usage it hath met withal) it is grown to a more virile Age and Vigour: But although =Chymistry= be much enlarged, and advanced in =England=, in respect of the Numbers, and Qualifications of the Lovers, and professors of it; yet are not Chymists free from pressing Disadvantages, not having the freedom of administring their own Medicines, how powerful and salutiferous soever, and otherwise adapted to the Necessities of the Sick, than the common =Apparatus= of Physick. So, that as the Case now stands, the help and Succour which the Sick and Diseased receive from Chymical Physick, is but very small to what they might have, if knowing Chymists had the freedom of exercising that Art in all its parts, which with much Industry, Labour, and Costs, they have been sollicitous to attain. But when this disincouragement of ingenuity and Obstacle of the publick good, shall become more apparent to those in whose power it is to redress it, I do not doubt but it will meet with a Remedy._ _But now, to give some account of my present undertaking. I have at length (by God’s help, and the assistance of my Subscribers) finished my Translation of =Glauber=’s =Works=, and here present it to the Reader, in the =English= Tongue. How well I have performed it, I must submit to the judgments of others: I could have been very glad to have seen it done by some abler hand; but when I have heretofore proposed the doing but of some parts of it to those whom I knew might easily have accommodated =English= Artists therein; telling them that I wondered so Excellent an Author, should be so long extant, and that none should unveil him of his =Latin= and =German= Coverings, and put him into an =English= Dress. I have had for answer, That this Age was not worthy of it; so that it seems to me, that the Providence of God had reserved it for fitter times, although to be done by one of the meanest of the Sons of =Pyrotechny=. But this I can say, that I have acquitted my self in this matter, as well as the slenderness of my Parts, weakness of Body, and the necessary Affairs of my Laboratory would permit me; but_ ----Ubi desint Vires, acceptanda est Voluntas.
