The following minerals, from the Ulster lead mine, were obtained from tho 

 proprietors of the mine : 



Four large specimens of Quartz Ckystals. 



Each of these specimens is a group of crystals of the ordinary form, 

 attached to each other. The specimens are truly magnificent, the largest 

 group weighing forty-six pounds. 



Also five large specimens of Groups of Quartz Crystals, interspersed 

 with copper pyrites and lead ore. These crystals are all terminated prisms; 

 and the specimens are, perhaps, equal in beauty to any ever obtained in 

 this State.
