Kázmér, M. ; Papp, G.: Minerals from the Carpathians in an eighteenth-century British collection
10 July 1725. p. 1. Vegetable bodies dug up out of the Earth. Parts of Trees and Shrubs found buried under Ground. a. 13. A piece of Wood dug up out of the Alum-Mines near Düben in Hungary. Sent by Dr. Kisner, of Francfort. <Frankfurt> {E-l 8-35} Piece of wood. Unusually light piece, not necessarily fossil - or saturated by alum only? This specimen probably hasn't come from Hungary. We are unable to identify Düben with any Hungarian locality, and according to SoÓS & SZŐKEFALVY-NAGY (1967) alum production in Hungary began only around 1760 and before this date the alum demands were satisfied by import from Italy. p. 10. Anomiae §.85. Another, dug up at the Depth of 50 fathom in an Iron-Mine, about 20 Miles from Newsohl <Neusohl>, Hungary. Mr. Weber. {E-22-24} A small rhynchonellid brachiopod. It is the first invertebrate fossil published from Hungary, p. 28. Bones, Teeth, &c of Fishes p.. 154. A small piece of Bone, having its Surface of a green Colour, and its interior Parts of a blue; broke off from a much larger. That is throughout the same Colour. It seems to be part of the scutellated Bone of a Sturgeon; being flat, of a porous or cellular Constitution on one side, tho' the Cells be somewhat worn down, and flatted; and smooth on the other. 'Tis about 1/10 of an Inch in thickness, 3 Inches long, and 1 Inch and broad. Taken up near Herngrundt <Herrengrund> in Hungary; colour'd by the Water of the rich Copper-Mines. Given me by Dr. Edward Brown, President of the College of Physicians. Those bodies that the Jewellers call Turcois-Stones, are no other than Pieces of Bones tinged blue by the Copper-Ore, amongst which they were lodg'd. These they cut, polish, and set in Rings. And indeed the same learned Gentleman, in his Travels, p. 68. informs us, that in those very Copper-Mines of Herngrundt, are stones found of a beautiful green and blue Colour; and one sort upon which Turcoises have been found, and therefore call'd the Mother of the Turcois. By this I am the better enabled to apprehend an obscure Passage in P. Poterius's Pharm. Spagyr. 1. 2. c. 25. where he says, that in the Cabinet of S. Cassiani del Pozzo at Rome, he saw "Turcois-Stones made of EburFossile, exactly like the true natural Turcoises, agreeing with them in all respects, in Colour, in Hardness, and in Virtues." {E-27-63} Annls hist.-nul.
