T^Zu YELLOW MUNDICK. Marchafeta. Pyrites Aureus • 
not for that it hath any Gol J in it, but is both within, and 
without, of a fhining Metallick yellow. As heavy, as moft 
Ores. Here are of various Figures $ as 
The ORBICULAR MARCHASITE 5 tuberated, about 
the bignefs of Hand- Ball. 
Another, leffer, and a little compreffed. 
The GRAP-MARCHASITE. March. BotryiJea. It con-
