 Dewey, "and melts, rather hardly, into a dark enamel.''

2. Colophonite. At Conway ? 



• 40. Magncsian Garnet. At Haddam. (Vide Cleaveland'e 

 Min. Vol. 2. p. 777.) 



41. Epidote. At Milford Hills, in primitive greenstone. 

 (Silliman.) Also at Litchfield and Washington, in graphic 

 granite and sienite; crystallized. (Brace,) Also at Had- 

 dam, crystallized. Also at Tolland. [Webster.) Also nt 

 Athol, Worcester county, Mass. in prismatic bladed crj^^s- 

 tals, associated with black radiated schorl and hornblende. 

 Also in Shutesbury, in small crystals in gneiss. It occurs 

 also in a great many other places, disseminated in various 

 rocks, and not very interesting. 



1. Zoisite. At Haddam. (Webster.') Also at Wardsbo- 

 rough, Vermont, in much compressed, greenish grey, pris- 

 matic crystals; sometimes a foot long and one or two inch- 

 es wide. (Dewey.) Discovered b}^ Dr. J. A. Allen. Also 

 at Leyden, Brattleborough and Westmoreland. (Hall.) 



2. Arenaceous Epidote. At Haddam. (Webster.) Also 

 at Shutesbury, Leyden, Shelburne, Buckland, Whately, 

 Belchertown, Monson, and a great number of places, in 

 hornblende and greeqstone slate. 



42. PreJinilc. Near New-Haven, in secondary green- 

 stone, in radiated masses, or in veins. Also at Woodbury, 

 in the same sort of rock, in mammillary, botryoidal and al- 

 most globular masses. (Sillimun.) Also between Simsbury 

 and Wintonbury, in mammillary masses in greenstone. 

 (Hayden.) Also in Deerfield, Greenfield, and, indeed, in 

 almost every part of the secondary greenstone ranges from 

 New-Haven to Gill; in all the forms mentioned above. In 

 Deerfield the radiated masses sometimes contain pyritous 

 copper. They occur there, also, on pseudomorphous quartz, 

 having evidently been formed since the decomposition of 

 the crystals originally occupying the cavities. In the same
