Now the Considerations that induce men to think that there are Elements, may be conveniently enough referr’d to two heads. Namely, the one, that it is necessary that Nature make use of Elements to constitute the bodies that are reputed Mixt. And the other, That the Resolution of such bodies manifests that nature had compounded them of Elementary ones.
In reference to the former of these Considerations, there are two or three things that I have to Represent.
And I will begin with reminding you of the Experiments I not long since related to you concerning the growth of pompions, mint, and other vegetables, out of fair water. For by those experiments its seems evident, that Water may be Transmuted into all the other Elements; from whence it may be inferr’d, both, That ’tis not every Thing Chymists will call Salt, Sulphur, or Spirit, that needs alwayes be a Primordiate and Ingenerable body. And that Nature may contex a Plant (though that be a perfectly mixt Concrete) without having all the Elements previously presented to her to compound it of. And, if you will allow the relation I mention’d out of Mounsieur De Rochas to be True; then may not only plants, but Animals and Minerals too, be produced out of Water, And however there is little doubt to be made, but that the plants my tryals afforded me as they were like in so many other respects to the rest of the plants of the same Denomination; so they would, in case I had reduc’d them to putrefaction, have likewise produc’d Wormes or other insects, as well as the resembling Vegetables are wont to do; so that Water may, by Various Seminal Principles, be successively Transmuted into both plants and Animals. And if we consider that not only Men, but even sucking Children are, but too often, Tormented with Solid Stones, but that divers sorts of Beasts themselves, (whatever Helmont against Experience think to the contrary) may be Troubled with great and Heavy stones in their Kidneys and Bladders, though they Feed but upon Grass and other Vegetables, that are perhaps but Disguised Water, it will not seem improbable that even some Concretes of a mineral Nature, may Likewise be form’d of Water.
We may further Take notice, that as a Plant may be nourisht, and consequently may Consist of Common water; so may both plants and Animals, (perhaps even from their Seminal Rudiments) consist of compound Bodies, without having any thing meerly Elementary brought them by nature to be compounded by them: This is evident in divers men, who whilst they were Infants were fed only with Milk, afterwards Live altogether upon Flesh, Fish, wine, and other perfectly mixt Bodies. It may be seen also in sheep, who on some of our English Downs or Plains, grow very fat by feeding upon the grasse, without scarce drinking at all. And yet more manifestly in the magots that breed and grow up to their full bignesse within the pulps of Apples, Pears, or the like Fruit. We see also, that Dungs that abound with a mixt Salt give a much more speedy increment to corn and other Vegetables than Water alone would do: And it hath been assur’d me, by a man experienc’d in such matters, that sometimes when to bring up roots very early, the Mould they were planted in was made over-rich, the very substance of the Plant has tasted of the Dung. And let us also consider a Graft of one kind of Fruit upon the upper bough of a Tree of another kind. As for instance, the Ciens of a Pear upon a White-thorne; for there the ascending Liquor is already alter’d, either by the root, or in its ascent by the bark, or both wayes, and becomes a new mixt body: as may appear by the differing qualities to be met with in the saps of several trees; as particularly, the medicinal vertue of the Birch-Water (which I have sometimes drunk upon Helmonts great and not undeserved commendation) Now the graft, being fasten’d to the stock must necessarily nourish its self, and produce its Fruit, only out of this compound Juice prepared for it by the Stock, being unable to come at any other aliment. And if we consider, how much of the Vegetable he feeds upon may (as we noted above) remain in an Animal; we may easily suppose, That the blood of that Animal who Feeds upon this, though it be a Well constituted Liquor, and have all the differing Corpuscles that make it up kept in order by one præsiding form, may be a strangely Decompounded Body, many of its parts being themselves decompounded. So little is it Necessary that even in the mixtures which nature her self makes in Animal and Vegetable Bodies, she should have pure Elements at hand to make her compositions of.
Having said thus much touching the constitution of Plants and Animals, I might perhaps be able to say as much touching that of Minerals, and even Metalls, if it were as easy for us to make experiment in Order to the production of these, as of those. But the growth or increment of Minerals being usually a work of excessively long time, and for the most part perform’d in the bowels of the Earth, where we cannot see it, I must instead of Experiments make use, on this occasion, of Observations.
That stones were not all made at once, but that are some of them now adayes generated, may (though it be deny’d by some) be fully prov’d by several examples, of which I shall now scarce alledg any other, then that famous place in France known by the name of Les Caves [Gentieres], where the Water falling from the upper Parts of the cave to the ground does presently there condense into little stones, of such figures as the drops, falling either severally or upon one another, and coagulating presently into stone, chance to exhibit. Of these stones some Ingenuous Friends of ours, that went a while since to visit that place, did me the favour to present me with some that they brought thence. And I remember that both that sober Relator of his Voyages, Van Linschoten, and another good Author, inform us that in the Diamond Mines (as they call them) in the East-Indies, when having dig’d the Earth, though to no great depth, they find Diamonds and take them quite away; Yet in a very few years they find in the same place new Diamonds produc’d there since. From both which Relations, especially the first, it seems probable that Nature does not alwayes stay for divers Elementary Bodies, when she is to produce stones. And as for Metals themselves, Authors of good note assure us, that even they were not in the beginning produc’d at once altogether, but have been observ’d to grow; so that what was not a Mineral or Metal before became one afterwards. Of this it were easie to alledg many testimonies of professed Chymists. But that they may have the greater authority, I shall rather present you with a few borrowed from more unsuspected writers. Sulphuris Mineram (as the inquisitive P. Fallopius notes) quæ nutrix est caloris subterranei[(158)] fabri seu Archæi fontium & mineralium, Infra terram citissime renasci testantur Historiæ Metallicæ. Sunt enim loca e quibus si hoc anno sulphur effossum fuerit; intermissa fossione per quadriennium redeunt fossores & omnia sulphure, ut [autea], rursus inveniunt plena. Pliny Relates, In Italiæ Insula Ilva, gigni ferri metallum. Strabo multo expressius; effossum ibi metallum semper regenerari. Nam si effossio spatio centum annorum intermittebatur, & iterum illuc revertebantur, fossores reperisse maximam copiam ferri regeneratam. Which history not only is countenanced by Fallopius, from the Incom which the Iron of that Island yielded the Duke of Florence in his time; but is mention’d more expressely to our purpose, by the Learned Cesalpinus. Vena (sayes he) ferri copiosissima est in Italia; ob eam nobilitata Ilva Tirrheni maris Insula incredibili copia, etiam nostris temporibus eam gignens: Nam terra quæ eruitur dum vena effoditur tota, procedente tempore in venam convertitur. Which last clause is therefore very notable, because from thence we may deduce, that earth, by a Metalline plastick principle latent in it, may be in processe of time chang’d into a metal. And even AgricolaIn Lygiis, ad Sagam opidum; in pratis eruitur ferrum, fossis ad altitudinem bipedaneam actis. Id decennio renatum denuo foditur non aliter ac Ilvæ ferrum. himself, though the Chymists complain of him as their adversary, acknowledges thus much and more; by telling us that at a Town called Saga in Germany, they dig up Iron in the Fields, by sinking ditches two foot deep; And adding, that within the space of ten years the Ditches are digged again for Iron since produced, As the same Metal is wont to be obtain’d in Elva. Also concerning Lead, not to mention what even Galen notes, that it will increase both in bulk and Weight if it be long kept in Vaults or Sellars, where the Air is gross and thick, as he collects from the smelling of those pieces of Lead that were imploy’d to fasten together the parts of old Statues. Not to mention this, I say, Boccacius Certaldus, as I find him Quoted by a Diligent Writer, has this Passage touching the Growth of Lead. Fessularum mons (sayes he) in Hetruria, Florentiæ civitati imminens, lapides plumbarios habet; qui si excidantur, brevi temporis spatio, novis incrementis instaurantur; ut (annexes my Author) tradit Boccacius Certaldus, qui id [compotissimum] esse scribit. Nihil hoc novi est; sed de eadem Plinius, lib. 34. Hist. Natur. cap. 17. dudum prodidit, Inquiens, mirum in his solis plumbi metallis, quod derelicta fertilius reviviscunt. In plumbariis secundo Lapide ab Amberga dictis ad Asylum recrementa congesta in cumulos, exposita solibus pluviisque paucis annis, redunt suum metallum cum fenore. I might Add to these, continues Carneades, many things that I have met with concerning the Generation of Gold and Silver. But, for fear of wanting time, I shall mention but two or three Narratives. The First you may find Recorded by Gerhardus the Physick Professor, in these Words. In valle (sayes he) [Joachimaca] argentum [gramini] modo & more e Lapidibus mineræ velut e radice excrevisse digiti Longitudine, testis est Dr. Schreterus, qui ejusmodi venas aspectu jucundas & admirabiles Domi sua aliis sæpe monstravit & Donavit. Item Aqua cærulea Inventa est Annebergæ, ubi argentum erat adhuc in primo ente, quæ coagulata redacta est in calcem fixi & boni argenti.
The other two Relations I have not met with in Latine Authours, and yet they are both very memorable in themselves, and as pertinent to our present purpose.
The first I meet with in the Commentary of Johannes Valehius upon the Kleine Baur, In which that Industrious Chymist Relates, with many circumstances, that at a Mine-Town (If I may so English the German Bergstat) eight miles or Leagues distant from Strasburg call’d Mariakirch, a Workman came to the Overseer, and desired employment; but he telling him that there was not any of the best sort at present for him, added that till he could be preferr’d to some such, he might in the mean time, to avoid idleness, work in a Grove or Mine-pit thereabouts, which at that time was little esteem’d. This Workman after some weeks Labour, had by a Crack appearing in the Stone upon a Stroak given near the wall, an Invitation Given him to Work his Way through, which as soon as he had done, his Eyes were saluted by a mighty stone or Lump which stood in the middle of the Cleft (that had a hollow place behind it) upright, and in shew like an armed-man; but consisted of pure fine Silver having no Vein or Ore by it, or any other Additament, but stood there free, having only underfoot something like a burnt matter; and yet this one Lump held in Weight above a 1000 marks, which, according to the [Dutch, Account] makes 500 pound weight of fine silver. From which and other Circumstances my Author gathers; That by the warmth of the place, the Noble Metalline Spirits, (Sulphureous and Mercurial) were carri’d from the neighbouring Galleries or Vaults, through other smaller Cracks and Clefts, into that Cavity, and there collected as in a close Chamber or Cellar; whereinto when they were gotten, they did in process of time settle into the forementioned precious mass of Metal.
The other Germane Relation is of That great Traveller and Laborious Chymist Johannes (not Georgus) Agricola; who in his notes upon what Poppius has written of Antimony, Relates, that when he was among the Hungarian Mines in the deep Groves, he observ’d that there would often arise in them a warm Steam (not of that malignant sort which the Germains call Shwadt, which (sayes he) is a meer poyson, and often suffocates the [Diggers], which fasten’d it self to the Walls; and that coming again to review it after a couple of dayes, he discern’d that it was all very fast, and glistering; whereupon having collected it and Distill’d it per Retortam, he obtain’d from it a fine Spirit, adding, that the Mine-Men inform’d him, that this Steam or [Damp of the English Mine] (retaining the dutch Term) would at last have become a Metal, as Gold or Silver.
I referr (sayes Carneades) to another Occasion, the Use that may be made of these Narratives towards the explicating the Nature of Metalls; and that of Fixtness, Malleableness, and some other Qualities conspicuous in them. And in the mean time, this I may at present deduce from these Observations, That ’tis not very probable, that, whensoever a Mineral, or even a Metall, is to be Generated in the Bowels of the Earth, Nature needs to have at hand both Salt, and Sulphur, and Mercury to Compound it of; for, not to urge that the two last Relations seem less to favour the Chymists than Aristotle, who would have Metals Generated of certain Halitus or steams, the foremention’d Observations together, make it seem more Likely that the mineral Earths or those Metalline steams (wherewith probably such Earths are plentifully imbu’d) do contain in them some seminal Rudiment, or some thing Equivalent thereunto; by whose plastick power the rest of the matter, though perhaps Terrestrial and heavy, is in Tract of time fashion’d into this or That metalline Ore; almost as I formerly noted, that fair water was by the seminal Principle of Mint, Pompions, and other Vegetables, contriv’d into Bodies answerable to such Seeds. And that such Alterations of Terrestrial matter are not impossible, seems evident from that notable Practice of the Boylers of Salt-Petre, who unanimously observe, as well here in England as in other Countries; That if an Earth pregnant with Nitre be depriv’d, by the affusion of water, of all its true and dissoluble Salt, yet the Earth will after some years yield them Salt-Petre again; For which reason some of the eminent and skillfullest of them keep it in heaps as a perpetual Mine of Salt Petre; whence it may appear, that the Seminal Principle of Nitre latent in the Earth does by degrees Transforme the neighbouring matter into a Nitrous Body; for though I deny that some Volatile Nitre may by such Earths be attracted (as they speak) out of the Air, yet that the innermost parts of such great heaps that lye so remote from the Air should borrow from it all the Nitre they abound with, is not probable, for other reasons besides the remoteness of the Air, though I have not the Leasure to mention them.
