' 9 ' not for that it hath any G old in it, but is both within, and 
without, of a (hining Metallick yellow. As heavy, as moll 
Ores. Here are of various Figures 5 as 
The ORBICULAR MARCH ASITE 3 tuberated, about 
the bignefs of Hand-Ball. 
Another, lefler, and a little compreffed. 
The GRAP-M ARCHASITE. March. Botryidea. It con-
