to the depth of half an inch, terminating in a kind of seam 
whee it is connected with the mass of Steatite. In both 
these respects, there is a close resemblance to some crystal- 
lizations of quartz, which are not pseudo-morphous. Stea- 
‘tite must, therefore, be considered as a mineral, which is 
erystallized, as well as amorphous, 
Z oisite, 
This variety of Epidote is found in abundance in Wards- 
borough, Vt. in quartz. The crystals are prismatic, gene- 
rally much. flattened, sometimes rounded, often aggregated, 
of a gray or greenish-gray colour, and varying in magnitude 
to a foot or more in length and one or two inches in breadth. 
They are distinctly striated, and have a pearly lustre. They 
much resemble the bladed crystals of Tremolite, but havea 
different and higher lustre, and the cross seams are nearly 
perpendicular to the sides. Before the blowpipe, the 
crystals are easily Zoisite is fused by t se 
compound blow-pipe into a black glass.

_ This mineral is found in the same masses with the Zoi-

like common chlorite, and seems to be passing into the
