 fpar, which, is the pretended mother of emerald 

 (Cronft. Mineral. 73.) 



12 Pyrites j fome cryftallifed into marcafitical 

 cubes ; in all Veiuvian collections. The fame 

 from Mtna. 



13. Ochracecus iron cre^ either compaft, or in 

 polygone comb-like cryftallifations ; in all Vefu- 

 vian collcdions; pretended to be from Vefuvius 

 or -ZEtna. But the very fame fpecies of iron-ore 

 being common in the mines of Ifola d'Elba* near 

 Tofcana, I doubt whether it really be a volcanic 

 production. 



14. Pyritical yellow copper -ore ; pretended to be 

 from Vefuvius or JEtna, It may be ; but I am 

 dubious. 



15. Malachites and azure copper-ore on quartz 

 and calcareous fpar. Pretended Vefuvian pro- 

 ductions j as, 



1 6. Striated grey antimony, and
