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 [Errata: 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 [Errata: 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 [Errata: damp as the Englishmen also call it] (retaining the dutch Term) would at last have become a Metal, as Gold or Silver.
