If (sayes Eleutherius) I durst presume that the same thing would be thought clear by me, and those that are fond of such cloudy Expressions as You justly Tax the Chymists for, I should venture to offer to Consideration, whether or no, since the Mercurial Principle that arises from Distillation is unanimously asserted to be distinct from the salt and Sulphur of the same Concrete, that may not be call’d the Mercury of a Body, which though it ascend in Distillation, as do the Phlegme and Sulphur, is neither insipid like the former, nor inflamable like the latter. And therefore I would substitute to the too much abused Name of Mercury, the more clear and Familiar Appellation of Spirit, which is also now very much made use of even by the Chymists themselves, of our times, though they have not given us so Distinct an Explication, as were fit, of what may be call’d the Spirit of a mixt Body.
I should not perhaps (sayes Carneades) much quarrel with your Notion of Mercury. But as for the Chymists, what they can mean, with congruity to their own Principles, by the Mercury of Animals and Vegetables, ’twill not be so easie to find out; for they ascribe Tasts only to the Saline Principle, and consequently would be much put to it to shew what Liquor it is, in the Resolution of Bodies, that not being insipid, for that they call Phlegme, neither is inflamable as Oyle or Sulphur, nor has any Tast; which according to them must proceed from a Mixture, at least, of Salt. And if we should take Spirit in the sence of the Word receiv’d among Modern Chymists and Physitians, for any Distill’d Liquor that is neither Phlegme nor oyle, the Appellation would yet appear Ambiguous enough. For, plainly, that which first ascends in the Distillation of Wine and Fermented Liquors, is generally as well by Chymists as others reputed a Spirit. And yet pure Spirit of Wine being wholly inflamable ought according to them to be reckon’d to the Sulphureous, not the Mercurial Principle. And among the other Liquors that go under the name of Spirits, there are divers which seem to belong to the family of Salts, such as are the Spirits of Nitre, Vitriol, Sea-Salt and others, and even the Spirit of Harts-horn, being, as I have try’d, in great part, if not totally reducible into Salt and Phlegme, may be suspected to be but a Volatile Salt disguis’d by the Phlegme mingl’d with it into the forme of a Liquor. However if this be a Spirit, it manifestly differs very much from that of Vinager, the Tast of the one being Acid, and the other Salt, and their Mixture in case they be very pure, sometimes occasioning an Effervescence like that of those Liquors the Chymists count most contrary to one another. And even among those Liquors that seem to have a better title then those hitherto mention’d, to the name of Spirits, there appears a sensible Diversity; For spirit of Oak, for instance, differs from that of Tartar, and this from that of Box, or of Guaiacum. And in short, even these spirits as well as other Distill’d Liquors manifest a great Disparity betwixt themselves, either in their Actions on our senses, or in their other operations.
And (continues Carneades) besides this Disparity that is to be met with among those Liquors that the Modernes call spirits, & take for similar bodies, what I have formerly told you concerning the Spirit of Box-wood may let you see that some of those Liquors not only have qualities very differing from others, but may be further resolved into substances differing from one another.
And since many moderne Chymists and other Naturalists are pleased to take the Mercurial spirit of Bodies for the same Principle, under differing names, I must invite you to observe, with me, the great difference that is conspicuous betwixt all the Vegetable and Animal spirits I have mention’d and running Mercury. I speak not of that which is commonly sold in shops that many of themselves will confesse to be a mixt Body; but of that which is separated from Metals, which by some Chymists that seem more Philosophers then the rest, and especially by the above mentioned Claveus, is (for distinction sake) called Mercurius Corporum. Now this Metalline Liquor being one of those three Principles of which Mineral Bodies are by Spagyrists affirmed to be compos’d and to be resoluble into them, the many notorious Differences betwixt them and the Mercuries, as They call Them, of Vegetables and Animals will allow me to inferr, either that Minerals and the other two sorts of Mixt Bodies consist not of the same Elements, or that those Principles whereinto Minerals are immediately resolved, which Chymists with great ostentation shew us as the true principles, of them, are but Secundary Principles, or Mixts of a peculiar sort, which must be themselves reduc’d to a very differing forme, to be of the same kind with Vegetable and Animal Liquors.
But this is not all; for although I formerly told You how Little Credit there is to be given to the Chymical Processes commonly to be met with, of Extracting the Mercuries of Metals, Yet I will now add, that supposing that the more Judicious of Them do not untruly affirme that they have really drawn true and running Mercury from several Metals (which I wish they had cleerly taught Us how to do also,) yet it may be still doubted whether such extracted Mercuries do not as well differ from common Quicksilver, and from one another, as from the Mercuries of Vegetables and Animalls. Claveus,Dixi autem de argento vivo a metallis prolicito, quod vulgare ob nimiam frigiditatem & humiditatem nimium concoctioni est contumax, nec ab auro solum alterato coerceri potest. Gast. Clave. in Apoll. in his Apology, speaking of some experiments whereby Metalline Mercuries may be fixt into the nobler metals, adds, that he spake of the Mercuries drawn from metals; because common Quicksilver by reason of its excessive coldnesse and moisture is unfit for that particular kind of operation; for which though a few lines before he prescribes in general the Mercuries of Metalline Bodies, yet he chiefly commends that drawn by art from silver. And elsewhere, in the same Book, he tells us, that he himself tryed, that by bare coction the quicksilver of Tin or Pewter (argentum vivum ex stanno prolicitum) may by an efficient cause, as he speaks, be turn’d into pure Gold. And the Experienc’d Alexander van Suchten, somewhere tells us, that by a way he intimates may be made a Mercury of Copper, not of the Silver colour of other Mercuries, but green; to which I shall add, that an eminent person, whose name his travells and learned writings have made famous, lately assur’d me that he had more then once seen the Mercury of Lead (which whatever Authors promise, you will find it very difficult to make, at least in any considerable quantity) fixt into perfect Gold. And being by me demanded whether or no any other Mercury would not as well have been changed by the same Operations, he assured me of the Negative.
And since I am fallen upon the mention of the Mercuries of metals, you will perhaps expect (Eleutherius!) that I should say something of their two other principles; but must freely confess to you, that what Disparity there may be between the salts and sulphurs of Metals and other Menerals, I am not my self experienced enough in the separations and examens of them, to venture to determine: (for as for the salts of Metals, I formerly represented it as a thing much to be question’d, whether they have any at all:) And for the processes of separation I find in Authors, if they were (what many of them are not) successfully practicable, as I noted above, yet they are to be performed by the assistance of other bodies, so hardly, if upon any termes at all, separable from them, that it is very difficult to give the separated principles all their due, and no more. But the Sulphur of Antimony which is vehemently vomitive, and the strongly scented Anodyne Sulphur of Vitriol inclines me to think that not only Mineral Sulphurs differ from Vegetable ones, but also from one another, retaining much of the nature of their Concretes. The salts of metals, and of some sort of minerals, You will easily guesse [by] the Doubts I formerly express’d, whether metals have any salt at [all], that I have not been so happy as yet to see, perhaps not for want of curiosity. But if Paracelsus did alwaies write so consentaneously to himself that his opinion were confidently to be collected from every place of his writings where he seems to expresse it, I might safely take upon me to tell you, that he both countenances in general what I have delivered in my Fourth main consideration, and in particular warrants me to suspect that there may be a difference in metalline and mineral Salts, as well as we find it in those of other bodies. For, Sulphur (sayes he)Paracel. de Mineral. Tract. 1. pag. 141. aliud in auro, aliud in argento, aliud in ferro, aliud in plumbo, stanno, &c. sic aliud in Saphiro, aliud in Smaragdo, aliud in rubino, chrysolito, amethisto, magnete, &c. Item aliud in lapidibus, silice, salibus, fontibus, &c. nec vero tot sulphura tantum, sed & totidem salia; sal aliud in metallis, aliud in gemmis, aliud in lapidibus, aliud in salibus, aliud in vitriolo, aliud in alumine: similis etiam Mercurii est ratio. Alius in Metallis, alius in Gemmis, &c. Ita ut unicuique speciei suus peculiaris Mercurius sit. Et tamen res saltem tres sunt; una essentia est sulphur; una est sal; una est Mercurius. Addo quod & specialius adhuc singula dividantur; aurum enim non unum, sed multiplex, ut et non unum pyrum, pomum, sed idem multiplex; totidem etiam sulphura auri, salia auri, mercurii auri; idem competit etiam metallis & gemmis; ut quot saphyri præstantiores, lævioris, &c. tot etiam saphyrica sulphura, saphyrica salia, saphyrici Mercurii, &c. Idem verum etiam est de turconibus & gemmis aliis universis. From which passage (Eleutherius) I suppose you will think I might without rashness conclude, either that my opinion is favoured by that of Paracelsus, or that Paracelsus his opinion was not alwaies the same. But because in divers other places of his writings he seems to talk at a differing rate of the three Principles and the four Elements, I shall content my self to inferr from the alledg’d passage, that if his doctrine be not consistent with that Part of mine which it is brought to countenance, it is very difficult to know what his opinion concerning salt, sulphur and mercury, was; and that consequently we had reason about the beginning of our conferences, to decline taking upon us, either to examine or oppose it.
I know not whether I should on this occasion add, that those very bodies the Chymists call Phlegme and Earth do yet recede from an Elementary simplicity. That common Earth and Water frequently do so, notwithstanding the received contrary opinion, is not deny’d by the more wary of the moderne Peripateticks themselves: and certainly, most Earths are much lesse simple bodies then is commonly imagined even by Chymists, who do not so consideratly to prescribe and employ Earths Promiscuously in those distillations that require the mixture of some caput mortuum, to hinder the flowing together of the matter, and to retain its grosser parts. For I have found some Earths to yield by distillation a Liquor very far from being inodorous or insipid; and ’tis a known observation, that most kinds of fat Earth kept cover’d from the rain, and hindred from spending themselves in the production of vegetables, will in time become impregnated with Salt-Petre.
But I must remember that the Water and Earths I ought here to speak of, are such as are separated from mixt Bodies by the fire; and therefore to restrain my Discourse to such, I shall tell you, That we see the Phlegme of Vitriol (for instance) is a very effectual remedie against burnes; and I know a very Famous and experienc’d Physitian, whose unsuspected secret (himself confess’d to me) it is, for the discussing of hard and Obstinate Tumours. The Phlegme of Vinager, though drawn exceeding leasurly in a digesting Furnace, I have purposely made tryall of; and sometimes found it able to draw, though slowly, a saccharine sweetness out of Lead; and as I remember by long Digestion, I dissolv’d [Corpals] in it. The Phlegme of the sugar of Saturne is said to have very peculiar properties. Divers Eminent Chymists teach, that it will dissolve Pearls, which being precipitated by the spirit of the same concrete are thereby (as they say) rendred volatile; which has been confirmed to me, upon his own observation, by a person of great veracity. The Phlegme of Wine, and indeed divers other Liquors that are indiscriminately condemnd to be cast away as phlegm, are endow’d with qualities that make them differ both from meer water, and from each other; and whereas the Chymists are pleas’d to call the caput mortuum of what they have distill’d (after they have by affusion of water drawn away its salt) terra damnata, or Earth, it may be doubted whether or no those earths are all of them perfectly alike: and it is scarce to be doubted, but that there are some of them which remain yet unreduc’d to an Elementary nature. The ashes of wood depriv’d of all the salt, and bone-Ashes, or calcin’d Harts-horn, which Refiners choose to make Tests of, as freest from Salt, seem unlike: and he that shall compare either of these insipid ashes to Lime, and much more to the calx of Talk (though by the affusion of water they be exquisitely dulcify’d) will perhaps see cause to think them things of a somewhat differing nature. And it is evident in Colcothar that the exactest calcination, follow’d by an exquisite dulcification, does not alwaies reduce the remaining body into elementary earth; for after the salt or Vitriol (if the Calcination have been too faint) is drawn out of the Colcothar, the residue is not earth, but a mixt body, rich in Medical vertues (as experience has inform’d me) and which Angelus Sala affirmes to be partly reducible into malleable Copper; which I judge very probable: for though when I was making Experiments upon Colcothar, I was destitute of a Furnace capable of giving a heat intense Enough to bring such a Calx to Fusion; yet having conjectur’d that if Colcothar abounded with that Metal, Aqua Fortis would find it out there, I put some dulcifi’d Colcothar into that Menstruum, and found the Liquor, according to my Expectation, presently Colour’d as Highly as if it had been an Ordinary Solution of Copper.
