The Sceptical Chymist Part 4

But before I descend to the Mention of Particulars belonging to my Fourth Consideration, I think it convenient to premise a few Generals; some of which I shall the less need to insist on at present, because I have Touched on them already.

And first I must invite you to take notice of a certain pa.s.sage in _Helmont_;[14] which though I have not Found much heeded by his Readers, He Himself _mentions_ as a notable thing, and I take to be a very considerable one; for whereas the Distill'd oyle of _oyle-olive_, though drawn _per se_ is (as I have try'd) of a very sharp and fretting Quality, and of an odious tast, He tells us that Simple oyle being only digested with _Paracelsus's sal circulatum_, is reduc'd into dissimilar parts, and yields a sweet Oyle, very differing from the oyle distill'd, from [Errata: distill'd from] sallet oyle; as also that by the same way there may be separated from Wine a very sweet and gentle Spirit, partaking of a far other and n.o.bler quality then that which is immediately drawn by distillation and call'd _Dephlegm'd Aqua vitae_, from whose Acrimony this other spirit is exceedingly remote, although the _sal circulatum_ that makes these _Anatomies_ be separated from the a.n.a.lyz'd Bodies, in the same weight and with the same qualities it had before; which Affirmation of _Helmont_ if we admit to be true, we must acknowledge that there may be a very great disparity betwixt bodies of the same denomination (as several oyles, or several spirits) separable from compound Bodies: For, besides the differences I shall anon take notice of, betwixt those distill'd Oyles that are commonly known to Chymists, it appears by this, that by means of the _Sal Circulatum_, There may be quite another sort of Oyles obtain'd from the same Body; and who knowes but that there may be yet other Agents found in Nature, by whose help there may, whether by Trans.m.u.tation or otherwise, be obtain'd from the Bodies Vulgarly call'd Mixt, Oyles or other substances, Differing from those of the same Denomination, known either to Vulgar Chymists, or even to _Helmont_ Himself: but for fear You should tell me, that this is but a conjecture grounded upon another Man's Relation, whose Truth we have not the means to Experiment, I will not Insist upon it; but leaving You to Consider of it at leasure, I shall proceed to what is next.

[Footnote 14: _Illud notabile, in vino esse Spiritum quendam mitiorem ulterioris & n.o.bilioris qualitatis participem qu[=a] qui immediate per distillationem elicitur diciturque aqua vitae dephlegmata, quod facilius in simplici Olivarum oleo ad oculum spectatur. Quippe distillatum oleum absque laterum aut tigularum [Errata: tegularum]

additamento, quodque oleum Philosophorum dicitur, multum dissert ab ejus oleitate; quae elicitur prius reducto oleo simplici in partes dissimilares sola digestione & Salis circulati Paracelsici appositione; siquidem sal circulatum idem in pondere & quant.i.tatibus pristinis ab oleo segregatur postquam oleum olivarum in sui heterogeneitates est dispositum. Dulce enim tunc Oleum Olivarum ex oleo, prout & suavissimus vini spiritus a vino hoc pacto separantur, longeque ab aquae vitae acrimonia distinctus._--Helmont. Aura vitalis, pag. 725.]

Secondly, Then if that be True which was the Opinion of _Lucippus_, _Democritus_, and other prime _Anatomists_ of old, and is in our dayes reviv'd by no mean Philosophers; namely, That our Culinary Fire, such as Chymists use, consists of swarmes of little Bodies swiftly moving, which by their smallness and motion are able to permeate the sollidest and Compactest Bodies, and even Gla.s.s it Self; If this (I say) be True, since we see that In flints and other Concretes, the Fiery part is Incorporated with the Grosser, it will not be Irrationall to conjecture, that mult.i.tudes of these Fiery Corpuscles, getting in at the Pores of the Gla.s.s, may a.s.sociate themselves with the parts of the mixt Body whereon they work, and with them Const.i.tute new Kinds of Compound Bodies, according as the Shape, Size, and other Affections of the Parts of the Dissipated Body happen to dispose them, in Reference to such Combinations; of which also there may be the greater Number; if it be likewise granted that the Corpuscles of the Fire, though all exceeding minute, and very swiftly moved, are not all of the same bigness, nor Figure. And if I had not Weightier Considerations to Discourse to you of, I could name to you, to Countenance what I have newly said, some particular Experiments by which I have been Deduc'd to think, that the Particles of an open Fire working upon some Bodies may really a.s.sociate themselves therewith, and add to the Quant.i.ty.

But because I am not so sure, that when the Fire works upon Bodies included in Gla.s.ses, it does it by a reall Trajection of the Fiery Corpuscles themselves, through the Substance of the Gla.s.s, I will proceed to what is next to be mention'd.

I could (sayes _Eleutherius_) help you to some Proofes, whereby I think it may be made very probable, that when the Fire acts immediately upon a Body, some of its Corpuscles may stick to those of the burnt Body, as they seem to do in Quicklime, but in greater numbers, and more permanently. But for fear of r.e.t.a.r.ding Your Progress, I shall desire you to deferr this Enquiry till another time, and proceed as you intended.

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 Fact.i.tious, 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 Ill.u.s.trated by reflecting upon what happens in some Chymical Preparations of those Medicines which they call their _Bezoardic.u.m'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 b.u.t.ter, 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 h.o.m.ogeneous enough, may be of a Compounded Nature, those parts of each body that are most of Kin a.s.sociating 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 pa.s.s 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 Quant.i.ty (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 Gla.s.s Retort, I obtain'd according to my Desire, (besides the two Liquors I had put in) a pretty Quant.i.ty 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 pa.s.s 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 _a.n.a.lysis_ 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 gla.s.s. 'Tis true, that the _a.n.a.lysis_ which the Chymists princ.i.p.ally 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 gla.s.ses 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 Const.i.tute 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 b.u.t.ter 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 quant.i.ty 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 Const.i.tute 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 n.o.ble and Permanent Body, Gla.s.s, 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 a.s.sertion 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 a.s.signe 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 fas.h.i.+on'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 pa.s.s 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 Gla.s.s made of ashes, where the exceeding strongly-tasted _Alcalizate_ Salt joyning with the Earth becomes insipid, and with it const.i.tutes 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 n.o.bis exprimit, & usque in prima nostri const.i.tutivasese 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 pa.s.s 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 a.s.sociated 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 Chymic.u.m_ teach us concerning the Destillation of _Saccharum Saturni_; out of which _Beguinus_[16] a.s.sures 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 const.i.tute the Spirit of Vinager, and so that what pa.s.ses 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 const.i.tute a Chymical Oyle, which therefore though it pa.s.s for h.o.m.ogeneous, 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 trans.m.u.ted 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 pa.s.sages 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 Trans.m.u.ted 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 a.s.sociated 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 Const.i.tution of Mixt bodies. So that one sort of these _Spagyrists_, notwithstanding the specious t.i.tles 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 h.o.m.ogeneous; 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 h.o.m.ogeneous, 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 a.n.a.logie 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 h.o.m.ogeneous. 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 h.o.m.ogeneous 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 Ma.s.ses 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 princ.i.p.ally 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 a.s.sertions. 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 pa.s.s 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 h.o.m.ogeneous, 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 dest.i.tute 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 const.i.tute the Essence of the Chymists Sulphur; as uninflamablenesse joyned with any taste is enough to int.i.tle 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 mult.i.tude 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 h.o.m.ogeneous,) 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 Ident.i.ty 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 _Guaiac.u.m_ (of which a great Quant.i.ty 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 Gla.s.se-house, that sometimes the Metal (as the Workmen call it) or Ma.s.se of colliquated Ingredients, which by Blowing they fas.h.i.+on 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 ign.o.bler kind of Gla.s.s 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 quant.i.ty 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 Diaph.o.r.etick 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. .h.i.therto 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.

[Footnote 18: _Error vero per distillationem n.o.bis monstrat etiam Spiritum salinum plane volatilem odore nequicquam ut nec gustu distinguibilem a spiritu Urinae; In eo tamen essentialiter diversum, quod spiritus talis cruoris curat Epilepsiam, non autem Spiritus salis lotii._ Helmont. Aura Vitalis.]

[Footnote 19: _Aliquando oleum Cinnamomi, &c. suo sali Alcali miscetur absque omni aqua, trium mensium Artificiosa occultaque circulatione, totum in salem volatilem commutatum est. Helmont. Tria Prima Chymicorum, &c. pag. 412._]

This Disparity is also highly eminent in the separated sulphurs or Chymical Oyles of things. For they contain so much of the scent, and tast, and vertues, of the Bodies whence they were drawn, that they seem to be but the Material _Crasis_ (if I may so speak) of their Concretes. Thus the Oyles of Cinnamon, Cloves, Nutmegs and other spices, seem to be but the United Aromatick parts that did enn.o.ble those Bodies. And 'tis a known thing, that Oyl of Cinnamon, and oyle of Cloves, (which I have likewise observ'd in the Oyles of several Woods) will sink to the Bottom of Water: whereas those of Nutmegs and divers other Vegetables will swim upon it. The Oyle (abusively call'd spirit) of Roses swims at the Top of the Water in the forme of a white b.u.t.ter, which I remember not to have observ'd in any other Oyle drawn in any Limbeck; yet there is a way (not here to be declar'd) by which I have seen it come over in the forme of other Aromatick Oyles, to the Delight and Wonder of those that beheld it. In Oyle of Anniseeds, which I drew both with, and without Fermentation, I observ'd the whole Body of the Oyle in a coole place to thicken into the Consistence and Appearance of white b.u.t.ter, which with the least heat resum'd its Former Liquidness. In the Oyl of Olive drawn over in a Retort, I have likewise more then once seen a spontaneous Coagulation in the Receiver: And I have of it by me thus Congeal'd; which is of such a strangely Penetrating scent, as if 'twould Perforate the Noses that approach it. The like pungent Odour I also observ'd in the Distill'd Liquor of common sope, which forc'd over from _Minium_, lately afforded an oyle of a most admirable Penetrancy; And he must be a great stranger, both to the Writings and preparations of Chymists, that sees not in the Oyles they distill from Vegetables and Animals, a considerable and obvious Difference. Nay I shall venture to add, _Eleutherius_, (what perhaps you will think of kin to a Paradox) that divers times out of the same Animal or Vegetable, there may be extracted Oyles of Natures obviously differing. To which purpose I shall not insist on the swimming and sinking Oyles, which I have sometimes observ'd to float on, and subside under the spirit of _Guajac.u.m_, and that of divers other Vegetables Distill'd with a strong and lasting Fire; Nor shall I insist on the observation elsewhere mention'd, of the divers and unminglable oyles afforded us by Humane Blood long fermented and Digested with spirit of Wine, because these kind of oyles may seem chiefly to differ in Consistence and Weight, being all of them high colour'd and adust. But the Experiment which I devis'd to make out this Difference of the oyles of the same Vegetable, _ad Oculum_, (as they speak) was this that followes. I took a pound of Annisseeds, and having grosly beaten them, caused them to be put into a very large gla.s.s Retort almost filled with fair Water; and placing this Retort in a sand Furnace, I caus'd a very Gentle heat to be administer'd during the first day, and a great part of the second, till the Water was for the most part drawn off, and had brought over with it at least most of the Volatile and Aromatick Oyle of the seeds. And then encreasing the Fire, and changing the Receiver, I obtain'd besides an Empyreumatical Spirit, a quant.i.ty of adust oyle; whereof a little floated upon the Spirit, and the rest was more heavy, and not easily separable from it. And whereas these oyles were very dark, and smell'd (as Chymists speak) so strongly of the Fire, that their Odour did not betray from what Vegetables they had been forc'd; the other _Aromatick_ Oyle was enrich'd with the genuine smell and tast of the Concrete; and spontaneously coagulating it self into white b.u.t.ter did manifest self [Errata: it self] to be the true Oyle of Annisseeds; which Concrete I therefore chose to employ about this Experiment, that the Difference of these Oyles might be more conspicuous then it would have been, had I instead of it destill'd another Vegetable.

I had almost forgot to take notice, that there is another sort of Bodies, which though not obtain'd from Concretes by Distillation, many Chymists are wont to call their Sulphur; not only because such substances are, for the most part, high colour'd (whence they are also, and that more properly, called Tinctures) as dissolv'd Sulphurs are wont to be; but especially because they are, for the most part, abstracted and separated from the rest of the Ma.s.se by Spirit of Wine: which Liquor those men supposing to be Sulphureous, they conclude, that what it works upon, and abstracts, must be a Sulphur also. And upon this account they presume, that they can sequester the sulphur even of Minerals and Metalls; from which 'tis known that they cannot by Fire alone separate it. To all This I shall answer; That if these sequestred substances where indeed the sulphurs of the Bodies whence they are drawn, there would as well be a great Disparity betwixt Chymical Sulphurs obtain'd by Spirit of Wine, as I have already shewn there is betwixt those obtain'd by Distillation in the forme of Oyles: which will be evident from hence, that not to urge that themselves ascribe distinct vertues to Mineral Tinctures, extolling the Tincture of Gold against such and such Diseases; the Tincture of Antimony, or of its Gla.s.s, against others; and the Tincture of Emerauld against others; 'tis plain, that in Tinctures drawn from Vegetables, if the superfluous spirit of Wine be distill'd off, it leaves at the bottom that thicker substance which Chymists use to call the Extract of the Vegetable. And that these Extracts are endow'd with very differing Qualities according to the Nature of the Particular Bodies that afforded them (though I fear seldom with so much of the specifick vertues as is wont to be imagin'd) is freely confess'd both by Physitians and Chymists. But, _Eleutherius_, (sayes _Carneades_) we may here take Notice that the Chymists do as well in this case, as in many others, allow themselves a License to abuse Words: For not again to argue from the differing properties of Tinctures, that they are not exactly pure and Elementary Sulphurs; they would easily appear not to be so much as Sulphur's, although we should allow Chymical Oyles to deserve that Name. For however in some Mineral Tinctures the Natural fixtness of the extracted Body does not alwayes suffer it to be easily further resoluble into differing substances; Yet in very many extracts drawn from Vegetables, it may very easily be manifested that the spirit of Wine has not sequestred the sulphureous Ingredient from the saline and Mercurial ones; but has dissolv'd (for I take it to be a Solution) the finer Parts of the Concrete (without making any nice distinction of their being perfectly Sulphureous or not) and united it self with them into a kind of Magistery; which consequently must contain Ingredients or Parts of several sorts. For we see that the stones that are rich in vitriol, being often drench'd with rain-Water, the Liquor will then extract a fine and transparent substance coagulable into Vitriol; and yet though this Vitriol be readily dissoluble in Water, it is not a true Elementary Salt, but, as You know, a body resoluble into very differing Parts, whereof one (as I shall have occasion to tell You anon) is yet of a Metalline, and consequently not of an Elementary Nature. You may consider also, that common Sulphur is readily dissoluble in Oyle of Turpentine, though notwithstanding its Name it abounds as well, if not as much, in Salt as in true Sulphur; witness the great quant.i.ty of saline Liquor it affords being set to flame away under a gla.s.se Bell. Nay I have, which perhaps You will think strange, with the same Oyle of Turpentine alone easily enough dissolv'd crude Antimony finely powder'd into a Blood-red Balsam, wherewith perhaps considerable things may be perform'd in Surgery. And if it were now Requisite, I could tell You of some other Bodies (such as Perhaps You would not suspect) that I have been able to work upon with certain Chymical Oyles. But instead of digressing further I shall make this use of the Example I have nam'd. That 'tis not unlikely, but that Spirit of Wine which by its pungent tast, and by some other Qualities that argue it better (especially its Reduciblenesse, according to _Helmont_, into _Alcali_, and Water,) seems to be as well of a Saline as of a Sulphureous Nature, may well be suppos'd Capable of Dissolving Substances That are not meerly Elementary sulphurs, though perhaps they may abound with Parts that are of kin thereunto. For I find that Spirit of Wine will dissolve _Gumm Lacca_, _Benzoine_, and the _Resinous_ Parts of _Jallap_, and even of _Guaiac.u.m_; whence we may well suspect that it may from Spices, Herbs, and other lesse compacted Vegetables, extract substances that are not perfect Sulphurs but mixt Bodies. And to put it past Dispute, there is many a Vulgar Extract drawn with Spirit of Wine, which committed to Distillation will afford such differing substances as will Loudly proclaim it to have been a very compounded Body. So that we may justly suspect, that even in Mineral Tinctures it will not alwaies follow, that because a red substance is drawn from the Concrete by spirit of Wine, that Substance is its true and Elementary Sulphur. And though some of these Extracts may perhaps be inflamable; Yet besides that others are not, and besides that their being reduc'd to such Minuteness of Parts may much facilitate their taking Fire; besides this, I say, We see that common Sulphur, common Oyle, Gumm Lac, and many Unctuous and Resinous Bodies, will flame well enough, though they be of very compounded natures: Nay Travellers of Unsuspected Credit a.s.sure Us, as a known thing, that in some Northern Countries where Firr trees and Pines abound, the poorer sort of Inhabitants use Long splinters of those Resinous Woods to burne instead of Candles. And as for the rednesse wont to be met with in such solutions, I could easily shew, that 'tis not necessary it should proceed from the Sulphur of the Concrete, Dissolv'd by the Spirit of Wine; if I had leasure to manifest how much Chymists are wont to delude themselves and others by the Ignorance of those other causes upon whose account spirit of Wine and other _Menstruums_ may acquire a red or some other high colour. But to returne to our Chymical Oyles, supposing that they were exactly pure; Yet I hope they would be, as the best spirit of Wine is, but the more inflamable and deflagrable.

And therefore since an Oyle can be by the Fire alone immediately turn'd into flame, which is something of a very differing Nature from it: I shall Demand how this Oyle can be a Primogeneal and Incorruptible Body, as most Chymists would have their Principles; Since it is further resoluble into flame, which whether or no it be a portion of the Element of Fire, as an _Aristotelian_ would conclude, is certainly something of a very differing Nature from a Chymical Oyle, since it burnes, and s.h.i.+nes, and mounts swiftly upwards; none of which a Chymical Oyle does, whilst it continues such. And if it should be Objected, that the Dissipated Parts of this flaming Oyle may be caught and collected again into Oyl or Sulphur; I shall demand, what Chymist appears to have ever done it; and without Examining whether it may not hence be as well said that sulphur is but compacted Fire, as that Fire is but diffus'd Sulphur, I shall leave you to consider whether it may not hence be argu'd, that neither Fire nor Sulphur are primitive and indestructible Bodies; and I shall further observe that, at least it will hence appear that a portion of matter may without being Compounded with new Ingredients, by having the Texture and Motion of its small parts chang'd, be easily, by the means of the Fire, endow'd with new Qualities, more differing from them it had before, then are those which suffice to discriminate the Chym
