was gilded over, and had a rich piece of Silver-ore, fastned in the middle of it, and this Inscription grav'd on the outside, Eisen ivare Ich, kupfer bin Ich, Silber trag Ich, Gold bedeckt mich. 20 i. e.Copper I am, but Iron was of old, Silver I carry, cover'd am with Gold. MINERALS GATHERED AT HERRENGRUND Cy he best source of information on minerals gathered at Herrengrund in the ti' late 17th century is the catalogue of the Museum of the Royal Society (GREW, 1681). Another work provoding numerous data on Hungarian minerals is the catalogue of a JOHN WOODWARD, a medical doctor of London (KÁZMÉR, 1998, KÁZMÉR & PAPP, 1999). His specimens are preserved - in original arrangement - in the Sedgwick Museum of the University of Cambridge (PRICE, 1989) Here the minerals from Herrengrund are listed following the system of GREW (1681). WOODWARD'S communications are inserted between GREW'S paragraphs. Their identification with valid scientific names needs further, possibly instrumental studies. „The MOTHER of the TURCOIS 21 , as i supposed. Found in the Mines of Herngrunt in Hungary, and given by Dr. Edward Browne. Here are two Pieces. One of them, the greatest part, blew; with some places black. In ivhich is also immersed a sort of small Sand-colourd Stones, so hard as to scratch Glass. The other, hath also a mixture of some parts that are green. The Blew and Green, are both, and they only dissoluble upon the effusion of Acids. The best of these Stones are the Blewest. (a) They have also this property; _c. to look blew by Day; (b) and Green by Candle-light. Many, faith Boetius 21 , have judged this to be reckon'd by Pliny, amongst jaspers with the Name of Boreas. But either Pliny and the Ancients, or those that make that judgement of them, ivere generally mistaken. For this is a very sofl Stone, and easily dissoluble with Ebullition, immediately upon te effusion of some, especially Nitrous Acids: and may be scraped with a Knife. So that I am of Opinion; That 'tis nothing else but a sort of Aerugo in some measure petrify 'd. Which also is further confirm'd in that
