THE CONCLUSION .

THese last Words of Carneades being soon after follow’d by a noise which seem’d to come from the place where the rest of the Company was, he took it for a warning, that it was time for him to conclude or break off his Discourse; and told his Friend; By this time I hope you see, Eleutherius, that if Helmonts Experiments be true, it is no absurdity to question whether that Doctrine be one, that doth not assert Any Elements in the sence before explain’d. But because that, as divers of my Arguments suppose the marvellous power of the Alkahest in the Analyzing of Bodies, so the Effects ascrib’d to that power are so unparallell’d and stupendious, that though I am not sure but that there may be such an Agent, yet little less than αυτοψια seems requisite to make a man sure there is. And consequently I leave it to you to judge, how farre those of my Arguments that are built upon Alkahestical Operations are weakned by that Liquors being Matchless; and shall therefore desire you not to think that I propose this Paradox that rejects all Elements, as an Opinion equally probable with the former part of my discourse. For by that, I hope, you are satisfied, that the Arguments wont to be brought by Chymists, to prove That all Bodies consist of either Three Principles, or Five, are far from being so strong as those that I have employ’d to prove, that there is not any certain and Determinate number of such Principles or Elements to be met with Universally in all mixt Bodies. And I suppose I need not tell you, that these Anti-Chymical Paradoxes might have been manag’d more to their Advantage; but that having not confin’d my Curiosity to Chymical Experiments, I who am but a young Man, and younger Chymist, can yet be but slenderly furnished with them, in reference to so great and difficult a Task as you impos’d upon me; Besides that, to tell you the Truth, I durst not employ some even of the best Experiments I am acquainted with, because I must not yet disclose them;
