YELLOW MUNDICK. Marchafita. Pyrites Aureus ■ 
not for that it hath any Gold in it, but is both within, and 
without, of a (Lining Metallick yellow. As heavy, as moft 
Ores. Here are of various Figures; as 
The ORBICULAR MARCHASITE; tuberated, about 
the bignefs of Hand-Ball. 
Another, leffer, and a little comprelTed. 
The GRAP-MARCHASITE. March. Botryidea. Itcon-
