Chapter VI: Part 6

You may then in the next place (sayes _Carneades_) observe with me, that not only there are some Bodies, as Gold, and Silver, which do not by the usual Examens, made by Fire, Discover themselves to be mixt; but if (as You may Remember I formerly told You) it be a De-compound Body that is Dissipable into several Substances, by being expos'd to the Fire it may be resolv'd into such as are neither Elementary, nor such as it was upon its last mixture Compounded of; but into new Kinds of mixts. Of this I have already given You some Examples in Sope, Sugar of Lead, and Vitrioll. Now if we shall Consider that there are some Bodies, as well Natural, (as that I last nam'd) as Factitious, manifestly De-compounded; That in the Bowells of the Earth Nature may, as we see she sometimes does, make strange Mixtures; That Animals are nourish'd with other Animals and Plants; And, that these themselves have almost all of them their Nutriment and Growth, _either_ from a certain Nitrous Juice Harbour'd in the Pores of the Earth, _or_ from the Excrements of Animalls, _or_ from the putrify'd Bodies, either of living Creatures or Vegetables, _or_ from other Substances of a Compounded Nature; If, I say, we consider this, it may seem probable, that there may be among the Works of Nature (not to mention those of Art) a greater Number of De-compound Bodies, then men take Notice of; And indeed, as I have formerly also observ'd, it does not at all appear, that all Mixtures must be of Elementary Bodies; but it seems farr more probable, that there are divers sorts of compound Bodies, even in regard of all or some of their Ingredients, consider'd Antecedently to their Mixture. For though some seem to be made up by the immediate Coalitions of the Elements, or Principles themselves, and therefore may be call'd _Prima Mista_, or _Mista Primaria_; yet it seems that many other Bodies are mingl'd (if I may so speak) at the second hand, their immediate Ingredients being not Elementary, but these primary Mixts newly spoken of; And from divers of these Secondary sort of Mixts may result, by a further Composition, a Third sort, and so onwards. Nor is it improbable, that some Bodies are made up of Mixt Bodies, not all of the same Order, but of several; as (for Instance) a Concrete may consist of Ingredients, whereof the one may have been a primary, the other a Secondary Mixt Body; (as I have in Native Cinnaber, by my way of Resolving it, found both that Courser the [Errata: delete "the"] part that seems more properly to be Oar, and a Combustible Sulphur, and a Running Mercury:) or perhaps without any Ingredient of this latter sort, it may be compos'd of Mixt Bodies, some of them of the first, and some of the third Kind; And this may perhaps be somewhat Illustrated by reflecting upon what happens in some Chymical Preparations of those Medicines which they call their _Bezoardicum's_. For first, they take Antimony and Iron, which may be look'd upon as _Prima Mista_; of these they compound a Starry _Regulus_, and to this they add according to their Intention, either Gold, or Silver, which makes with it a new and further Composition. To this they add Sublimate, which is it self a De-compound body, (consisting of common Quicksilver, and divers Salts United by Sublimation into a Crystalline Substance) and from this Sublimate, and the other Metalline Mixtures, they draw a Liquor, which may be allow'd to be of a yet more Compounded Nature. If it be true, as Chymists affirm it, that by this Art some of the Gold or Silver mingl'd with the _Regulus_ may be carry'd over the Helme with it by the Sublimate; as indeed a Skilfull and Candid person complain'd to me a while since, That an experienc'd Friend of His and mine, having by such a way brought over a great Deal of Gold, in hope to do something further with it, which might be gainfull to him, has not only miss'd of his Aim, but is unable to recover his Volatiliz'd Gold out of the Antimonial butter, wherewith it is strictly united.

Now (Continues _Carneades_) if a Compound body consist of Ingredients that are not meerly Elementary; it is not hard to conceive, that the Substances into which the Fire Dissolves it, though seemingly Homogeneous enough, may be of a Compounded Nature, those parts of each body that are most of Kin associating themselves into a Compound of a new Kind. As when (for example sake) I have caus'd Vitrioll and _Sal Armoniack_, and Salt Petre to be mingl'd and Destill'd together, the Liquor that came over manifested it self not to be either Spirit of Nitre, or of _Sal Armoniack_, or of Vitrioll. For none of these would dissolve crude gold, which yet my Liquor was able readily to do; and thereby manifested it self to be a new Compound, consisting at least of Spirit of Nitre, and _Sal Armoniack_, (for the latter dissolv'd in the former, will Work on Gold) which nevertheless are not by any known way separable, and consequently would not pass for a Mixt Body, if we our selves did not, to obtain it, put and Distill together divers Concretes, whose Distinct Operations were known before hand. And, to add on this Occasion the Experiment I lately promis'd You, because it is Applicable to our present purpose, I shall Acquaint You, that suspecting the Common Oyle of Vitrioll not to be altogether such a simple Liquor as Chymists presume it, I mingl'd it with an equal or a Double Quantity (for I try'd the Experiment more then once) of common Oyle of Turpentine, such as together with the other Liquor I bought at the Drugsters. And having carefully (for the Experiment is Nice, and somewhat dangerous) Distill'd the Mixture in a small Glass Retort, I obtain'd according to my Desire, (besides the two Liquors I had put in) a pretty Quantity of a certain substance, which sticking all about the Neck of the Retort Discover'd it self to be Sulphur, not only by a very strong Sulphureous smell, and by the colour of Brimstone; but also by this, That being put upon a coal, it was immediately kindl'd, and burn'd like common Sulphur. And of this Substance I have yet by me some little Parcells, which You may command and examine when you please. So that from this Experiment I may deduce either one, or both of these Propositions, That a real Sulphur may be made by the Conjunction of two such Substances as Chymists take for Elementary, And which did not either of them apart appear to have any such body in it; or that Oyle of Vitrioll though a Distill'd Liquor, and taken for part of the Saline Principle of the Concrete that yields it, may yet be so Compounded a body as to contain, besides its Saline part, a Sulphur like common brimstone, which would hardly be it self a simple or un-compounded body.

I might (pursues _Carneades_) remind You, that I formerly represented it, as possible, That as there may be more Elements then five, or six; so the Elements of one body may be Different from those of another; whence it would follow, that from the Resolution of De-compound body [Errata: bodies], there may result Mixts of an altogether new kind, by the Coalition of Elements that never perhaps conven'd before. I might, I say, mind You of this, and add divers things to this second Consideration; but for fear of wanting time I willingly pretermit them, to pass on to the third, which is this, That the Fire does not alwayes barely resolve or take asunder, but may also after a new manner mingle and compound together the parts (whether Elementary or not) of the Body Dissipated by it.

This is so evident, sayes _Carneades_, in some obvious Examples, that I cannot but wonder at their Supiness that have not taken notice of it. For when Wood being burnt in a Chimney is dissipated by the Fire into Smoke and Ashes, that smoke composes soot, which is so far from being any one of the principles of the Wood, that (as I noted above) you may by a further _Analysis_ separate five or six distinct substances from it. And as for the remaining Ashes, the Chymists themselves teach us, that by a further degree of fire they may be indissolubly united into glass. 'Tis true, that the _Analysis_ which the Chymists principally build upon is made, not in the open air, but in close Vessels; but however, the Examples lately produc'd may invite you shrewdly to suspect, That heat may as well compound as dissipate the Parts of mixt Bodies: and not to tell you, that I have known a Vitrification made even in close vessels, I must remind you that the Flowers of Antimony, and those of Sulphur, are very mix'd Bodies, though they ascend in close vessells: And that 'twas in stopt glasses that I brought up the whole Body of Camphire. And whereas it may be objected, that all these Examples are of Bodies forc'd up in a dry, not a Fluid forme, as are the Liquors wont to be obtain'd by distillation; I answer, That besides that 'tis possible, that a Body may be chang'd from Consistent to Fluid, or from Fluid to Consistent, without being otherwise much altered, as may appear by the Easiness wherewith in Winter, without any Addition or Separation of Visible Ingredients, the same substance may be quickly harden'd into brittle Ice, and thaw'd again into Fluid Water; Besides this, I say it would be consider'd, that common Quick-silver it self, which the Eminentest Chymists confess to be a mixt Body, may be Driven over the Helme in its Pristine forme of Quicksilver, and consequently, in that of a Liquor. And certainly 'tis possible that very compounded Bodies may concur to Constitute Liquors; Since, not to mention that I have found it possible, by the help of a certain _Menstruum_, to distill Gold it self through a Retort, even with a Moderate Fire: Let us but consider what happens in Butter of Antimony. For if that be carefully rectify'd, it may be reduc'd into a very clear Liquor; and yet if You cast a quantity of fair water upon it, there will quickly precipitate a Ponderous and Vomitive Calx, which made before a considerable part of the Liquor, and yet is indeed (though some eminent Chymists would have it Mercurial) an Antimonial Body carryed over and kept dissolv'd by the Salts of the Sublimate, and consequently a compounded one; as You may find if You will have the Curiosity to Examine this White powder by a skilful Reduction. And that You may not think that Bodies as compounded as flowers of Brimstone cannot be brought to Concurr to Constitute Distill'd Liquors; And also That You may not imagine with Divers Learned Men that pretend no small skill in Chymistry, that at least no mixt Body can be brought over the Helme, but by corrosive Salts, I am ready to shew You, when You please, among other wayes of bringing over Flowers of Brimstone (perhaps I might add even Mineral Sulphurs) some, wherein I employ none but Oleaginous bodies to make Volatile Liquors, in which not only the colour, but (which is a much surer mark) the smell and some Operations manifest that there is brought over a Sulphur that makes part of the Liquor.

One thing more there is, _Eleutherius_, sayes _Carneades_, which is so pertinent to my present purpose, that though I have touch'd upon it before, I cannot but on this occasion take notice of it. And it is this, That the Qualities or Accidents, upon whose account Chymists are wont to call a portion of Matter by the name of Mercury or some other of their Principles, are not such but that 'tis possible as Great (and therefore why not the like?) may be produc'd by such changes of Texture, and other Alterations, as the Fire may make in the small Parts of a Body. I have already prov'd, when I discours'd of the second General Consideration, by what happens to plants nourish'd only with fair water, and Eggs hatch'd into Chickens, that by changing the disposition of the component parts of a Body, Nature is able to effect as great Changes in a parcell of Matter reputed similar, as those requisite to Denominate one of the _Tria Prima_. And though _Helmont_ do somewhere wittily call the Fire the Destructor and the Artificial Death of Things; And although another Eminent Chymist and Physitian be pleas'd to build upon this, That Fire can never generate any thing but Fire; Yet You will, I doubt not, be of another mind, If You consider how many new sorts of mixt Bodies Chymists themselves have produc'd by means of the Fire: And particularly, if You consider how that Noble and Permanent Body, Glass, is not only manifestly produc'd by the violent action of the Fire, but has never, for ought we know, been produc'd any other way. And indeed it seems but an inconsiderate Assertion of some _Helmontians_, that every sort of Body of a Peculiar Denomination must be produc'd by some Seminal power; as I think I could evince, if I thought it so necessary, as it is for me to hasten to what I have further to discourse. Nor need it much move us, that there are some who look upon whatsoever the Fire is employ'd to produce, not as upon Natural but Artificial Bodies. For there is not alwaies such a difference as many imagine betwixt the one and the other: Nor is it so easy as they think, clearly to assigne that which Properly, Constantly, and Sufficiently, Discriminates them. But not to engage my self in so nice a Disquisition, it may now suffice to observe, that a thing is commonly termed Artificial, when a parcel of matter is by the Artificers hand, or Tools, or both, brought to such a shape or Form, as he Design'd before-hand in his Mind: Whereas in many of the Chymical Productions the effect would be produc'd whether the Artificer intended it or no; and is oftentimes very much other then he Intended or Look't for; and the Instruments employ'd, are not Tools Artificially fashion'd and shaped, like those of Tradesmen, for this or that particular Work; but, for the most part, Agents of Nature's own providing, and whose chief Powers of Operation they receive from their own Nature or Texture, not the Artificer. And indeed, the Fire is as well a Natural Agent as Seed: And the Chymist that imployes it, does but apply Natural Agents and Patients, who being thus brought together, and acting according to their respective Natures, performe the worke themselves; as Apples, Plums, or other fruit, are natural Productions, though the Gardiner bring and fasten together the Sciens of the Stock, and both Water, and do perhaps divers other wayes Contribute to its bearing fruit. But, to proceed to what I was going to say, You may observe with me, _Eleutherius_, that, as I told You once before, Qualities sleight enough may serve to Denominate a Chymical Principle. For, when they anatomize a compound Body by the Fire, if they get a Substance inflamable, and that will not mingle with Water, that they presently call Sulphur; what is sapid and Dissoluble in Water, that must pass for Salt; Whatsoever is fix'd and indissoluble in Water, that they name Earth. And I was going to add, that, whatsoever Volatile substance they know not what to make of, not to say, whatsoever they please, that they call Mercury. But that these Qualities may either be produc'd, otherwise then by such as they call Seminal Agents, or may belong to bodies of a compounded Nature, may be shewn, among other Instances, in Glass made of ashes, where the exceeding strongly-tasted _Alcalizate_ Salt joyning with the Earth becomes insipid, and with it constitutes a Body, which though also dry, fixt, and indissoluble in Water, is yet manifestly a mixt Body; and made so by the Fire itself.

And I remmember to our present purpose, that _Helmont_,[15] amongst other Medicines that he commends, has a short processe, wherein, though the Directions for Practice are but obscurely intimated; yet I have some reason not to Dis-believe the Process, without affirming or denying any thing about the vertues of the remedy to be made by it. _Quando_ (sayes he) _oleum cinnamomi &c. suo sali alkali miscetur absque omni aqua, trium mensium artificiosa occultaque circulatione, totum in salem volatilem commutatum est, vere essentiam sui simplicis in nobis exprimit, & usque in prima nostri constitutivasese ingerit._ A not unlike Processe he delivers in another place; from whence, if we suppose him to say true, I may argue, that since by the Fire there may be produc'd a substance that is as well Saline and volatile as the Salt of Harts-horn, blood, &c. which pass for Elementary; and since that this Volatile Salt is really compounded of a Chymical Oyle and a fixt Salt, the one made Volatile by the other, and both associated by the fire, it may well be suspected that other Substances, emerging upon the Dissipation of Bodies by the Fire, may be new sorts of Mixts, and consist of Substances of differing natures; and particularly, I have sometimes suspected, that since the Volatile Salts of Blood, Harts-horn, &c. are figitive [Errata: fugitive] and endow'd with an exceeding strong smell, either that Chymists do Erroneously ascribe all odours to sulphurs, or that such Salts consist of some oyly parts well incorporated with the Saline ones. And the like conjecture I have also made concerning Spirit of Vinager, which, though the Chymists think one of the Principles of that Body, and though being an Acid Spirit it seems to be much less of kin then Volatile Salts to sulphurs; yet, not to mention its piercing smell; which I know not with what congruity the Chymist will deduce from Salt, I wonder they have not taken notice of what their own _Tyrocinium Chymicum_ teach us concerning the Destillation of _Saccharum Saturni_; out of which _Beguinus_[16] assures Us, that he distill'd, besides a very fine spirit, no lesse then two Oyles, the one blood-red and ponderous, but the other swimming upon the top of the Spirit, and of a yellow colour; of which he sayes that he kept then some by him, to verify what he delivers. And though I remember not that I have had two distinct Oyles from Sugar of Lead, yet that it will though distill'd without addition yield some Oyle, disagrees not with my Experience. I know the Chymists will be apt to pretend, that these Oyls are but the volatiliz'd sulphur of the lead; and will perhaps argue it from what _Beguinus_ relates, that when the Distillation is ended, you'l find a _Caput Mortuum_ extreamly black, and (as he speaks) _nullius momenti_, as if the Body, or at least the chief part of the Metal it self were by the distillation carried over the Helme. But since you know as well as I that _Saccharum Saturni_ is a kind of Magistery, made only by calcining of Lead _per se_, dissolving it in distill'd Vinager, and crystalizing the solution; if I had leasure to tell You how Differing a thing I did upon examination find the _Caput Mortuum_, so sleighted by _Beguinus_, to be from what he represents it, I believe you would think the conjecture propos'd less probable then one or other of these three; either that this Oyle did formerly concur to constitute the Spirit of Vinager, and so that what passes for a Chymical Principle may yet be further resoluble into distinct substances; or that some parts of the Spirit together with some parts of the Lead may constitute a Chymical Oyle, which therefore though it pass for Homogeneous, may be a very compounded Body: or at least that by the action of the Distill'd Vinager and the Saturnine Calx one upon another, part of the Liquor may be so alter'd as to be transmuted from an Acid Spirit into an Oyle. And though the truth of either of the two former conjectures would make the example I have reflected on more pertinent to my present argument; yet you'l easily discern, the Third and last Conjecture cannot be unserviceable to confirm some other passages of my discourse.

[Footnote 15: Helmont pag. 412.]

[Footnote 16: Tyroc. Chym. L. 1. C. 4.]

To return then to what I was saying just before I mention'd _Helmont's_ Experiment, I shall subjoyne, That Chymists must confess also that in the perfectly Dephlegm'd spirit of Wine, or other Fermented Liquors, that which they call the Sulphur of the Concrete loses, by the Fermentation, the Property of Oyle, (which the Chymists likewise take to be the true Sulphur of the Mixt) of being unminglable with the Water. And if You will credit _Helmont_,[17] all [Errata: a pound] of the purest Spirit of Wine may barely by the help of pure Salt of Tartar (which is but the fixed Salt of Wine) be resolv'd or Transmuted into scarce half an ounce of Salt, and as much Elementary Water as amounts to the remaining part of the mention'd weight. And it may (as I think I formerly also noted) be doubted, whether that Fixt and Alcalizate Salt, which is so unanimously agreed on to be the Saline Principle of incinerated Bodies, be not, as 'tis Alcalizate, a Production of the Fire? For though the tast of Tartar, for Example, seem to argue that it contains a Salt before it be burn'd, yet that Salt being very Acid is of a quite Differing Tast from the Lixiviate Salt of Calcin'd Tartar. And though it be not truly Objected against the Chymists, that they obtain all Salts they make, by reducing the Body they work on into Ashes with Violent Fires, (since Hartshorn, Amber, Blood, and divers other Mixts yield a copious Salt before they be burn'd to Ashes) yet this Volatile Salt Differs much, as we shall see anon, from the Fixt Alcalizate Salt I speak of; which for ought I remember is not producible by any known Way, without Incineration. 'Tis not unknown to Chymists, that Quicksilver may be Precipitated, without Addition, into a dry Powder, that remains so in Water. And some eminent _Spagyrists_, and even _Raimund Lully_ himself, teach, that meerly by the Fire Quicksilver may in convenient Vessels be reduc'd (at least in great part) into a thin Liquor like Water, and minglable with it. So that by the bare Action of the Fire, 'tis possible, that the parts of a mixt Body should be so dispos'd after new and differing manners, that it may be sometimes of one consistence, sometimes of another; And may in one State be dispos'd to be mingl'd with Water, and in another not. I could also shew you, that Bodies from which apart Chymists cannot obtain any thing that is Combustible, may by being associated together, and by the help of the Fire, afford an inflamable Substance. And that on the other side, 'tis possible for a Body to be inflamable, from which it would very much puzzle any ordinary Chymist; and perhaps any other, to separate an inflamable Principle or Ingredient. Wherefore, since the Principles of Chymists may receive their Denominations from Qualities, which it often exceeds not the power of Art, nor alwayes that of the Fire to produce; And since such Qualities may be found in Bodies that differ so much in other Qualities from one another, that they need not be allow'd to agree in that pure and simple Nature, which Principles, to be so indeed, must have; it may justly be suspected, that many Productions of the Fire that are shew'd us by Chymists, as the Principles of the Concrete that afforded them, may be but a new kind of Mixts. And to annex, on this Occasion, to these arguments taken from the Nature of the thing, one of those which _Logicians_ call _ad Hominem_, I shall desire You to take Notice, that though _Paracelsus_ Himself, and some that are so mistaken as to think he could not be so, have ventur'd to teach, that not only the bodies here below, but the Elements themselves, and all the other Parts of the Universe, are compos'd of Salt, Sulphur and Mercury; yet the learned _Sennertus_, and all the more wary Chymists, have rejected that conceit, and do many of them confess, that the _Tria Prima_ are each of them made up of the four Elements; and others of them make Earth and Water concur with Salt, Sulphur and Mercury, to the Constitution of Mixt bodies. So that one sort of these _Spagyrists_, notwithstanding the specious Titles they give to the productions of the Fire, do in effect grant what I contend for. And, of the other sort I may well demand, to what Kind of Bodies the Phlegme and dead Earth, to be met with in Chymical Resolutions, are to be referr'd? For either they must say, with _Paracelsus_, but against their own Concessions as well as against Experience, that these are also compos'd of the _Tria Prima_, whereof they cannot separate any one from either of them; or else they must confess that two of the vastest Bodies here below, Earth, and Water, are neither of them compos'd of the _Tria Prima_; and that consequently those three are not the Universal, and Adequate Ingredients, neither of all Sublunary Bodies, nor even of all mixt Bodies.

[Footnote 17: _Ostendi alias, quomodo lib. una aquae vitae combibita in sale Tartari siccato, vix fiat semuncia salis, caeterum totum corpus fiat aqua Elementalis. Helmont. in Aura vitali._]

I know that the chief of these Chymists represent, that though the Distinct Substances into which they divide mixt bodies by the Fire, are not pure and Homogeneous; yet since the four Elements into which the _Aristotelians_ pretend to resolve the like bodies by the same Agent, are not simple neither, as themselves acknowledge, 'tis as allowable for the Chymists to call the one Principles, as for the Peripateticks to call the other Elements; since in both cases the Imposition of the name is grounded only upon the Predominancy of that Element whose name is ascrib'd to it. Nor shall I deny, that this Argument of the Chymists is no ill one against the _Aristotelians_. But what Answer can it prove to me, who you know am disputing against the _Aristotelian_ Elements, as the Chymicall Principles, and must not look upon any body as a true Principle or Element, but as yet compounded, which is not perfectly Homogeneous, but is further Resoluble into any number of Distinct Substances how small soever. And as for the Chymists calling a body Salt, or Sulphur, or Mercury, upon pretence that the Principle of the same name is predominant in it, That it self is an Acknowledgment of what I contend for; namely that these productions of the Fire, are yet compounded bodies. And yet whilst this is granted, it is affirm'd, but not prov'd, that the reputed Salt, or Sulphur, or Mercury, consists mainly of one body that deserves the name of a principle of the same Denomination. For how do Chymists make it appear that there are any such primitive and simple bodies in those we are speaking of; since 'tis upon the matter confess'd by the answer lately made, that these are not such? And if they pretend by Reason to evince what they affirm, what becomes of their confident boasts, that the Chymists [Errata: Chymist] (whom they therefore, after _Beguinus_, call a _Philosophus_ or _Opifex Sensatus_) can convince our Eyes, by manifestly shewing in any mixt body those simple substances he teaches them to be compos'd of? And indeed, for the Chymists to have recourse in this case to other proofs then Experiments, as it is to wave the grand Argument that has all this while been given out for a Demonstrative One; so it releases me from the obligation to prosecute a Dispute wherein I am not engag'd to Examine any but Experimentall proofs. I know it may plausibly Enough be Represented, in favour of the Chymists, that it being evident that much the greater part of any thing they call Salt, or Sulphur, or Mercury, is really such; it would be very rigid to deny those Substances the names ascribed them, only because of some sleight mixture of another Body; since not only the Peripateticks call particular parcels of matter Elementary, though they acknowledge that Elements are not to be anywhere found pure, at least here below; And since especially there is a manifest Analogie and Resemblance betwixt the bodies obtainable by Chymical Anatomies and the principles whose names are given them; I have, I say, consider'd that these things may be represented: But as for what is drawn from the Custome of the Peripateticks, I have already told You, that though it may be employ'd against Them, Yet it is not available against me who allow nothing to be an Element that is not perfectly Homogeneous. And whereas it is alledg'd, that the Predominant Principle ought to give a name to the substance wherein it abounds; I answer, that that might much more reasonably be said, if either we or the Chymists had seen Nature take pure Salt, pure Sulphur, and pure Mercury, and compound of them every sort of Mixt Bodies. But, since 'tis to experience that they appeal, we must not take it for granted, that the Distill'd Oyle (for instance) of a plant is mainly compos'd of the pure principle call'd Sulphur, till they have given us an ocular proof, that there is in that sort of Plants such an Homogeneous Sulphur. For as for the specious argument, which is drawn from the Resemblance betwixt the Productions of the Fire, and the Respective, either _Aristotelian_ Elements, or _Chymical_ Principles, by whose names they are call'd; it will appear more plausible then cogent, if You will but recall to mind the state of the controversie; which is not, whether or no there be obtain'd from mixt Bodies certain substances that agree in outward appearance, or in some Qualities with Quicksilver or Brimstone, or some such obvious or copious Body; But whether or no all Bodies confess'd to be perfectly mixt were compos'd of, and are resoluble into a determinate number of primary unmixt Bodies. For, if you keep the state of the question in your Eye, you'l easily discerne that there is much of what should be Demonstrated, left unprov'd by those Chymical Experiments we are Examining. But (not to repeat what I have already discover'd more at large) I shall now take notice, that it will not presently follow, that because a Production of the Fire has some affinity with some of the greater Masses of matter here below, that therefore they are both of the same Nature, and deserve the same Name; for the Chymists are not content, that flame should be look't upon as a parcel of the Element of Fire, though it be hot, dry, and active, because it wants some other Qualities belonging to the nature of Elementary fire. Nor will they let the Peripateticks call Ashes, or Quicklime, Earth, notwithstanding the many likenesses between them; because they are not tastlesse, as Elementary Earth ought to be: But if you should ask me, what then it is, that all the Chymical Anatomies of Bodies do prove, if they prove not that they consist of the three Principles into which the fire resolves them? I answer, that their Dissections may be granted to prove, that some mixt bodies (for in many it will not hold) are by the fire, when they are included in close Vessels, (for that Condition also is often requisite) dissolube [Transcriber's Note: dissoluble] into several Substances differing in some Qualities, but principally in Consistence. So that out of most of them may be obtain'd a fixt substance partly saline, and partly insipid, an unctuous Liquor, and another Liquor or more that without being unctuous have a manifest taste. Now if Chymists will agree to call the dry and sapid substance salt, the Unctous liquor Sulphur, and the other Mercury, I shall not much quarrel with them for so doing: But if they will tell me that Salt, Sulphur, and Mercury, are simple and primary bodies whereof each mixt body was actually compounded, and which was really in it antecedently to the operation of the fire, they must give me leave to doubt whether (whatever their other arguments may do) their Experiments prove all this. And if they will also tell me that the Substances their Anatomies are wont to afford them, are pure and similar, as Principles ought to be, they must give me leave to believe my own senses; and their own confessions, before their bare Assertions. And that you may not (_Eleutherius_) think I deal so rigidly with them, because I scruple to Take these Productions of the Fire for such as the Chymists would have them pass for, upon the account of their having some affinity with them; consider a little with me, that in regard an Element or Principle ought to be perfectly Similar and Homogeneous, there is no just cause why I should rather give the body propos'd the Name of this or that Element or Principle, because it has a resemblance to it in some obvious Quality, rather then deny it that name upon the account of divers other Qualities, wherein the propos'd Bodies are unlike; and if you do but consider what sleight and easily producible qualities they are that suffice, as I have already more then once observ'd, to Denominate a Chymical Principle or an Element, you'l not, I hope, think my wariness to be destitute either of Example, or else of Reason. For we see that the Chymists will not allow the _Aristotelians_ that the Salt in Ashes ought to be called Earth, though the Saline and Terrestrial part symbolize in weight, in dryness, in fixness and fusibility, only because the one is sapid and dissoluble in Water, and the other not: Besides, we see that sapidness and volatility are wont to denominate the Chymists Mercury or Spirit; and yet how many Bodies, think you, may agree in those Qualities which may yet be of very differing natures, and disagree in qualities either more numerous, or more considerable, or both. For not only Spirit of Nitre, Aqua Fortis, Spirit of Salt, Spirit of Oyle of Vitriol, Spirit of Allome, Spirit of Vinager, and all Saline Liquors Distill'd from Animal Bodies, but all the Acetous Spirits of Woods freed from their Vinager; All these, I say, and many others must belong to the Chymists Mercury, though it appear not why some of them should more be comprehended under one denomination then the Chymists Sulphur, or Oyle should likewise be; for their Distill'd Oyles are also Fluid, Volatile, and Tastable, as well as their Mercury; Nor is it Necessary, that their Sulphur should be Unctuous or Dissoluble in Water, since they generally referr Spirit of Wine to Sulphurs, although that Spirit be not Unctuous, and will freely mingle with Water. So that bare Inflamability must constitute the Essence of the Chymists Sulphur; as uninflamablenesse joyned with any taste is enough to intitle a Distill'd Liquor to be their Mercury. Now since I can further observe to You, that Spirit of Nitre and Spirit of Harts-horne being pour'd together will boile and hisse and tosse up one another into the air, which the Chymists make signes of great Antipathy in the Natures of Bodies (as indeed these Spirits differ much both in Taste, Smell, and Operations;) Since I elsewhere tell you of my having made two sorts of Oyle out of the same mans blood, that would not mingle with one another; And since I might tell You Divers Examples I have met with, of the Contrariety of Bodies which according to the Chymists must be huddl'd up together under one Denomination; I leave you to Judge whether such a multitude of Substances as may agree in these sleight Qualities, and yet Disagree in Others more Considerable, are more worthy to be call'd by the Name of a Principle (which ought to be pure and homogeneous,) than to have appellations given them that may make them differ, in name too, from the bodies from which they so wildly differ in Nature. And hence also, by the bye, you may perceive that 'tis not unreasonable to distrust the Chymists way of Argumentation, when being unable to shew us that such a Liquor is (for Example) purely saline, they prove, that at least salt is much the predominant principle, because that the propos'd substance is strongly tasted, and all Tast proceeds from salt; whereas those Spirits, such as spirit of Tartar, spirit of Harts-horn, and the like, which are reckoned to be the Mercuries of the Bodies that afford them, have manifestly a strong and piercing tast, and so has (according to what I formerly noted) the spirit of Box &c. even after the acid Liquor that concurr'd to compose it has been separated from it. And indeed, if sapidness belong not to the spirit or Mercurial Principle of Vegitables and Animals: I scarce know how it will be discriminated from their phlegm, since by the absence of Inflamability it must be distinguish'd from their sulphur, which affords me another Example, to prove how unacurate the Chymical Doctrine is in our present Case; since not only the spirits of Vegitables and Animals, but their Oyles are very strongly tasted, as he that shall but wet his tongue with Chymical Oyle of Cinnamon, or of Cloves, or even of Turpentine, may quickly find, to his smart. And not only I never try'd any Chymical Oyles whose tast was not very manifest and strong; but a skilful and inquisitive person who made it his business by elaborate operations to depurate Chymical Oyles, and reduce them to an Elementary simplicity, Informes us, that he never was able to make them at all Tastless; whence I might inferr, that the proof Chymists confidently give us of a bodies being saline, is so far from demonstrating the Predominancy, that it does not clearly Evince so much as the presence of the saline Principle in it. But I will not (pursues _Carneades_) remind you, that the Volatile salt of Harts-horn, Amber, Blood, &c. are exceeding strongly scented, notwithstanding that most Chymists deduce Odours from Sulphur, and from them argue the Predominancy of that Principle in the Odorous body, because I must not so much as add any new Examples of the incompetency of this sort of Chymical arguments; since having already detain'd You but too long in those generals that appertain to my fourth consideration, 'tis time that I proceed to the particulars themselves, to which I thought fit they should be previous:

These Generals (continues _Carneades_) being thus premis'd, we might the better survey the Unlikeness that an attentive and unprepossess'd observer may take notice of in each sort of Bodies which the Chymists are wont to call the salts or sulphurs or Mercuries of the Concretes that yield Them, as if they had all a simplicity, and Identity of Nature: whereas salts if they were all Elementary would as little differ as do the Drops of pure and simple Water. 'Tis known that both Chymists and Physitians ascribe to the fixt salts of calcin'd Bodies the vertues of their concretes; and consequently very differing Operations. So we find the _Alkali_ of Wormwood much commended in distempers of the stomach; that of Eyebright for those that have a weak sight; and that of _Guaiacum_ (of which a great Quantity yields but a very little salt) is not only much commended in Venereal Diseases, but is believed to have a peculiar purgative vertue, which yet I have not had occasion to try. And though, I confess, I have long thought, that these _Alkalizate_ salts are, for the most part, very neer of kin, and retain very little of the properties of the Concretes whence they were separated; Yet being minded to Observe watchfully whether I could meet with any Exceptions to this General Observation, I observ'd at the Glasse-house, that sometimes the Metal (as the Workmen call it) or Masse of colliquated Ingredients, which by Blowing they fashion into Vessels of divers shapes, did sometimes prove of a very differing colour, and a somewhat differing Texture, from what was usuall. And having enquired whether the cause of such Accidents might not be derived from the peculiar Nature of the fixt salt employ'd to bring the sand to fusion, I found that the knowingst Workmen imputed these Mis-adventures to the Ashes, of [Errata: Ashes off] some certain kind of Wood, as having observ'd the ignobler kind of Glass I lately mention'd to be frequently produc'd when they had employ'd such sorts of Ashes which therefore they scruple to make use of, if they took notice of them beforehand. I remember also, that an Industrious Man of my acquaintance having bought a vast quantity of Tobacco stalks to make a fixt Salt with, I had the Curiosity to go see whether that Exotick Plant, which so much abounds in volatile salt, would afford a peculiar kind of _Alcali_; and I was pleas'd to find that in the _Lixivium_ of it, it was not necessary, as is usual, to evaporate all the Liquor, that there might be obtain'd a Saline Calx, consisting like lime quench'd in the Air of a heap of little Corpuscles of unregarded shapes; but the fixt salt shot into figur'd Crystal, almost as Nitre or _Sal-armoniack_ and other uncalcin'd salts are wont to do; And I further remember that I have observ'd in the fixt Salt of Urine, brought by depuration to be very white, a tast not so unlike to that of common salt, and very differing from the wonted caustick Lixiviate tast of other salts made by Incineration. But because the Instances I have alledg'd of the Difference of _Alcalizate_ salt are but few, and therefore I am still inclin'd to think, that most Chymists and many Physitians do, inconsideratly enough and without Warrant from Experience, ascribe the Vertues of the Concretes expos'd to Calcination, to the salts obtain'd by it; I shall rather, to shew the Disparity of salts, mention in the first Place the apparent Difference betwixt the Vegetable fixt salts and the Animal Volatile ones: As (for Example) betwixt salt of Tartar, and salt of Harts-horn; whereof the former is so fixt that 'twill indure the brunt of a violent Fire, and stand in fusion like a Metal; whereas the other (besides that it has a differing tast and a very differing smell) is so far from being fixt, that it will fly away in a gentle heat as easily as Spirit of Wine it self. And to this I shall add, in the next place, That even among the Volatile salts themselves, there is a considerable Difference, as appears by the distinct Properties of (for Instance) salt of Amber, salt of Urine, salt of Mans Skull, (so much extoll'd against the falling Sicknesse) and divers others which cannot escape an ordinary Observer. And this Diversity of Volatile salts I have observ'd to be somtimes Discernable even to the Eye, in their Figures. For the salt of Harts-horn I have observ'd to adhere to the Receiver in the forme almost of a _Parallelipipedon_; and of the Volatile salt of humane blood (long digested before distillation, with spirit of Wine) I can shew you store of graines of that Figure which _Geometricians_ call a _Rhombus_; though I dare not undertake that the Figures of these or other Saline Crystals (if I may so call Them) will be alwaies the same, whatever degree of Fire have been employ'd to force them up, or how hastily soever they have been made to convene in the spirits or liquors, in the lower part of which I have usually observ'd them after a while to shoot. And although, as I lately told You, I seldom found any Difference, as to Medical Vertues, in the fixt Salts of Divers Vegetables; and accordingly I have suspected that most of these volatile Salts, having so great a Resemblance in smell, in tast, and fugitiveness, differ but little, if at all, in their Medicinal properties: As indeed I have found them generally to agree in divers of them (as in their being somewhat Diaphoretick and very Deopilative; [Errata: Deopilative)] Yet I remember _Helmont_[18] somewhere informes us, that there is this Difference betwixt the saline spirit of Urine and that of Mans blood, that the former will not cure the Epilepsy, but the Latter will. Of the Efficacy also of the Salt of Common Amber against the same Disease in Children, (for in Grown Persons it is not a specifick) I may elsewhere have an Occasion to Entertain You. And when I consider that to the obtaining of these Volatile Salts (especially that of Urine) there is not requisite such a Destructive Violence of the Fire, as there is to get those Salts that must be made by Incineration, I am the more invited to conclude, that they may differ from one another, and consequently recede from an Elementary Simplicity. And, if I could here shew You what Mr. _Boyle_ has Observ'd, touching the Various Chymicall Distinctions of Salts; You would quickly discern, not only that Chymists do give themselves a strange Liberty to call Concretes Salts, that are according to their own Rules to be look'd upon as very Compounded Bodies; but that among those very Salts that seem Elementary, because produc'd upon the Anatomy of the Bodies that yield them, there is not only a visible Disparity, but, to speak in the common Language, a manifest Antipathy or Contrariety: As is evident in the Ebullition and hissing that is wont to ensue, when the Acid Spirit of Vitrioll, for Instance, is pour'd upon pot ashes, or Salt of Tartar. And I shall beg leave of this Gentleman, sayes _Carneades_, casting his Eyes on me, to let me observe to You out of some of his papers, particularly those wherein he treats of some Preparations of Urine, that not only one and the same body may have two Salts of a contrary Nature, as he exemplifies in the Spirit and _Alkali_ of Nitre; but that from the same body there may without addition be obtain'd three differing and Visible Salts. For He Relates, that he observ'd in Urine, not only a Volatile and Crystalline Salt, and a fixt Salt, but likewise a kind of _Sal Armoniack_, or such a Salt as would sublime in the form of a salt, and therefore was not fixt, and yet was far from being so fugitive as the Volatile salt; from which it seem'd also otherwise to differ. I have indeed suspected that this may be a _Sal Armoniack_ properly enough so call'd, as Compounded of the Volatile salt of Urine, and the fixt of the same Liquor, which, as I noted, is not unlike sea-salt; but that it self argues a manifest Difference betwixt the salts, since such a Volatile salt is not wont to Unite thus with an ordinary _Alcali_, but to fly away from it in the Heat. And on this occasion I remember that, to give some of my Friends an Ocular proof of the difference betwixt the fixt and Volatile salt (of the same Concrete) Wood, I devis'd the following Experiment. I took common Venetian sublimate, and dissolv'd as much of it as I well could in fair Water: then I took Wood Ashes, and pouring on them Warme Water, Dissolv'd their salt; and filtrating the Water, as soon as I found the _Lixivium_ sufficiently sharp upon the tongue, I reserv'd it for use: Then on part of the former solution of sublimate dropping a little of this Dissolv'd Fixt salt of Wood, the Liquors presently turn'd of an Orange Colour; but upon the other part of the clear solution of sublimate putting some of the Volatile salt of Wood (which abounds in the spirit of soot) the Liquor immediately turn'd white, almost like Milke, and after a while let fall a white sediment, as the other Liquor did a Yellow one. To all this that I have said concerning the Difference of salts, I might add what I Formerly told you, concerning the simple spirit of Box, and such like Woods, which differ much from the other salts hitherto mention'd, and yet would belong to the saline Principle, if Chymists did truly teach that all Tasts proceed from it. And I might also annex, what I noted to you out of _Helmont_[19] concerning Bodies, which, though they consist in great part of Chymical Oyles, do yet appear but Volatile salts; But to insist on these things, were to repeat; and therefore I shall proceed.
