Dutchess Couxty. In tlie town of Kliinebeck, 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,

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 sjjhene and 

 pyroxene. 



Two miles southeast of Amitv, crystal- 

 lized epidote occurs in a vein in quartz. 

 The crystals are often very jjcrfect, and 

 have a rich grass-green colour. The forms 

 are those represented in Fig. 351 ; Fig. 

 354, the monostiquc of Haiiy ; and the twin.
