feet crystal. It was in possession ot the late Dr. Andrews, of Charlotte. 
Dr. Andrews informed me that a very beautiful diamond of consid- 
erable size, like a small chinkapin, and of black color, had been found at 
tne same locality, by three persons, while washing for gold. In their 
ignorance, believing that it could not be broken, they smashed it to pieces. 
Dr. Andrews tested the hardness of a fragment, which scratched corrun 
dum with facility, proving it to be a diamond. A very beautiful octahe- 
dral diamond ot first water has been found many years ago at the Portis’ 
Mine, Franklin coounty. There is a report that a second one has been 
found at the same locality. 
11. Graph tie. 
Graphite has been found at numerous localities. It forms large beds in 
the gneissoid and micaceous schists; sometimes very minute scales arc 
disseminated thaough the micaceous rocks. In most places it is yet too 
impure and gritty, at others purer, and better varieties have been obtained. 
The largest beds occur in Wake county, others in Lincoln, Cleavelaud, 
Catawba, Alexander, Stokes, Surry, Wilkes, Person and Yancey counties.

In very minute crystals and specks in the chloritic slate associated with 
gold, chalcopyrite and pyrite at the Barnhardt vein of Gold II111, Rowan 
county. 
13. TetKADYMITE, VAR 2. SULPHUROUS. 
This rare mineral has been found associated with gold in quartz at 
David Beck’s Mine, five miles west of Silver Hill, in Davidson county ;

Mine, Cullen’s Mine, at the Asbury vein, in Gaston county, at Capt.
