But now this green oyl further without fire may at last (after the preparing of many fair colours between) be reduced to a blood red, sweet and pleasant oyl, which goeth far beyond the green both in pleasantness and vertue, and is in comparison to it like a ripe grape to an unripe: Hereof happily shall be spoken at another time, because occasion and time will not permit me now to proceed further in it. And therefore the Philo-Chymical Reader is desired for the present to be contented with the green oyl, to prepare it carefully, and to use it with discretion; and doubtless he will get more credit by it, and do more wonderful things then hitherto hath been done by the heavy corrosive oyl. _The use and Dose of the sweet oyl of Vitriol._ Of this green oyl, there may be taken from 1. 2. 4. 8. 10. or 12. drops at once, according to the condition of the patient and the disease, in fit Vehicles, in Wine or Beer, in the morning fasting, as other medicines are usually taken: Also the Dose may be increased or lessened, and as often reiterated as the disease shall require. This Oyl expelleth all ill humors, not only by stoole and vomits, but also by urin and sweating, according as it doth meet with superfluities; and this very safely, and without any danger at all; whereby many diseases radically or perfectly may be cured. Let no man wonder that I ascribe such great vertues unto this oyl, it coming from such a despicable stone, and its preparation requiring no great Art or paines, as those intricate deceitful processes do, that are every where extant in books quite filled up with them. And it is no marvel, that men are in love with such false and costly processes; for the most of them do not believe, that any good is to be found in things that are not in esteem; but only make great account of dear things, far fetcht, and requiring much time and paines for to be prepared. Such men do not believe the word of God, testifying, _That God is no respecter of persons_, but that all men that fear and love him, are accepted of him. If this be true (which no good Christian will doubt) then we must believe also, that God created Physick or the matter of Physick as well for the poor as for the rich. Now if it be also for the poor, then certainly such will be the condition thereof, that it may be obtained by them, and easily prepared for use. So we see that Almighty God causeth not only in great mens grounds to come forth good Vegetables, Animals and Minerals, for the curing of the infirmities of mankind, but that the same also are found every where else. Whereby we perceive, that it is also the will of God, that they shall be known by all men, and that he alone, as the Maker of all good, may be praised and magnified by all men for the same.
