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.
