Dutchess County. In the town of Rhinebeck, granular epidote occurs in a ferruginous 
green feldspar; and it is also said to have been found at Hudson, in Columbia county.* 
Essex County. Epidote, in small imperfect crystals of a fine greenish yellow colour, is 
found associated with quartz, feldspar and mica, in the town of Crown-Point, and about five 
miles north of the village of Alexandria. 
New-York County. This mineral occurs in small yellowish green and very beautifully 
finished crystals, in gneiss at Har¬ 
lem, on the banks of the East 
river, near 38th-street, and in 
other parts of the island. The 
most common forms of these crys¬ 
tals are represented in Fig. 351, 
bisunitaire of Haiiy, and Fig. 352.

Orange County. At Bog Meadow pond in the town of Cornwall, 
there is a locality of massive and somewhat fibrous epidote of a fine 
greenish yellow colour. 
About two miles north of Coffee’s, in the town of Monroe, it is in 
dark grass-green crystals in granite. The forms are the primary and 
the six-sided prism, Fig. 353. 
Six miles west of the village of Warwick, the massive variety occurs 
of a pale yellowish green colour. It is associated with sphene and 
pyroxene.

Two miles southeast of Amity, crystal¬ 
lized epidote occurs in a vein in quartz. 
The crystals are often very perfect, and 
have a rich grass-green colour. The forms 
are those represented in Fig. 351 ; Fig. 
354, the monostique of Haiiy ; and the twin, 
Fig. 355, similar to that figured by Shepard 
as from Franconia in New-Hampshire. The 
axis of revolution is parallel to the prismatic 
axis, and the angle of revolution 180°. M
