Variety of Copper and Lead Ores from very distant Mines, and some of Tin with Mundick and Pyrites; most of them the Gift of the learned and ingenious Dr. Woodward, as a Copper Ore from Westmoreland; another (with Spar) from Cornwal; a third from Mr. Basset's Mine; a 4th (with Tin in it) from a different Mine of Mr. Basset's; a 5th from Sir. Will. Godolphin's, all in the said County; a 6th with Spar pretty rich in Tin. A Copper Ore from Devonshire; and another from Cheshire. One from the Mines near Richmond in Yorkeshire. Another very rich. Don. R. Gale Arm. One that I brought from Talentire in Cumberland. Another sent me by Ste. Tempest of Broughton, in Craven Esq;. But the greatest Curiosity relating to this Metal was sent me from Sweden by Mr. William Sykes Merchant, An 1688, when (and never else, as I am informed) several of them were found in the Copper Grove at Fallum: it is a most regular Octoedra, hath six angular Points, and consequently eight solid Triangles, or as many Pyramids joined in Base; the Figure of it may be seen in the Phil. Trans. N° 277. It is not unusual for Metals, as well as their Fluores or Spars, to strike into various and exact Mathematical Figures, wherein Nature seems to attempt what she hath brought to Perfection in this, which is the most curious, and in the Opinion of most competent Judges, beyond any Thing that hath been seen in its Kind. My Lord Bishop of Carlisle obliged me with a Specimen of Lead Ore and Sulphur pick'd up at the Out-bursts of their several Veins that have begun to shoot out in such regular Forms.
