But some one will object, that my vegetable spirits are not pure by reason of the ferment that is mixed, having in it self a spirit. I answer, there is not so great a portion of the ferment mixed which can corrupt the vegetable spirit. For although some spoonfuls of ferment yielding but a few drops of spirits be added to a great quantity of the vegetables; yet there can come no hurt or detriment to so many quarts of the vegetable spirit. I have seen some supercilious men that would not add ferment to the matter of their spirit, but sugar or honey, by which they would promote fermentation, and so have thought to get a pure spirit, not considering that honey and sugar, after fermentation are made to yield their spirit also, whereof one spoonful yields more than ten or twenty of Barm: But hony and sugar fermenting not without difficulty themselves, how can they promote the fermentation of other things? Who also have had experience, that the addition of their ferment hath been superfluous, whilst their flowers and hearbs have stood some weeks in maceration, before they begun to ferment, and that often times they have contracted an acidity, mustiness and stink, the reason of which was an unsutable ferment. There are indeed the fruits of some trees that have a sweet and full juice, as grapes, cherries, apples, pears, figs, _&c._ which need not the addition of any ferment, having a natural ferment of their own, but other vegetables not so, being lean, as hearbs, flowers and roots. It is necessary there to promote the fermentation of them by the addition of a sutable ferment, lest in length of time these hearbs and seeds lose their spirit exhaling in maceration. And thus much I was willing to say for information sake, and indeed for the sake of them who seek after the best and choicest medicines, wanting a good burning spirit as a companion applicable to them. For this spirit came not only by it self, as _Aqua vitæ_, into a medicinal use as well internal as external, especially that which is prepared of cordial, and cephalick hearbs; but also being united with the proper oyls of those hearbs in many desperate diseases, where it could put forth its vertues eminently. And thus much sufficeth concerning the preparation of vegetables that goes before the distillation of burning spirits. _The manner of distilling in general followeth._
