Now this preparation, which is the most hurtful poyson, a terror unto all the living, is nothing else but a _fulmen terrestre_ denouncing unto us the wrath and coming of the Lord. For Christ to judge the world is to come with thundering and lightning: and this earthly thunder perchance is given us for to put us in mind and fear of that which is to come, but this is not so much as thought on by men, who prepare it only for to plague and destroy mankind therewith in a most cruel and abominable manner, as every one knoweth. For none can deny but that there is no nimbler poyson, than this gunpowder. It is written of the Basiliske, that he killeth man only by his look, which a man may avoid, and there are but few (if any at all) of them found: but this poyson is now prepared and found every where. How often doth it fall out, that a place wherein this powder is kept is stricken with thunder as with its like, in so much that all things above it are in a moment destroyed, and carryed up into the air? Also in sieges, when an Ordnance is discharged, or Mines blown up, all whom it lays hold on, are suddenly killed, and most miserably destroyed. What nimbler poyson then could there be invented? I believe there is none, who will not acknowledge it to be such. And seeing that the ancient Philosophers and Chymists were always of opinion, that the greater the poyson is, the better medicine may be made of it, after it is freed from the poyson, which with us their posterity is proved true by many experiences; as we see by Antimony, Arsenick, Mercury, and the like minerals, which without preparation are meer poyson, but by due preparation may be turned into the best and most effectual medicaments, which though not every one can comprehend or believe, yet Chymists know it to be true, and the doing of it is no new thing to them. And because I treat in this second part of medicinal spirits, and other good medicaments, and finding that this which can be made out of gunpowder, is none of the least, I would not omit in some measure, and as far as lawfully may be done, to set down its preparation: which is thus performed. _How to make a spirit of Gunpowder._ Your distilling vessel being made warm, and a great receiver with sweet water in it, being applyed to it without luting, put a dish with gunpowder, containing about 12. or 15. grains a piece, one after another into it; in the same manner as above was taught to do with gold. For if you should put in too much of it at once, it would cause too much wind and break the receiver.
