470 MINERALS IN THE [December, 



since, on the Brandywine, eastern side, about two miles 

 beyond Westchester, on the opposite side of the creek 

 from James JefFeris's farm. It is there found in pieces of 

 blue quartz in the road. Mr. Lukens has also found it 

 lately, about fifteen miles on the York road. Within a 

 few weeks, Mr. A. E. Jessup has found it to occur on the 

 Schuylkill, about ten miles from the city, in a rock simi- 

 lar to that of Trenton. 



Pistazite, Epidote, H. 



Pistazite, both massive and crystallized, wes found 

 by Mr. Vanuxem and myself, in a large piece of quartz, 

 about one fourth of a mile above the upper bridge on the 

 Schuylkill, western side, and nearly one hundred yards 

 from the river. It did not appear to be exactly in place, 

 as it was found on a pile of other stones. Colour, yel- 

 lowish olive. Form hexaedral prism with diedral sum- 

 mits. 



Zoizite, Epidote, H. 



Zoizite occurs in the hornblende rocks of the quar- 

 ly, end of canal road, in acicular crystals and fasiculated, 

 sometimes associated with zeolite, and rutilite. Colour, 

 grayish, and has a slight pearly lustre, 



Melanite, 



Mr. C. Wister is mentioned by Cleveland as having 

 found this mineral, imbedded in gneiss, back of Ger- 

 mantown, six miles from the city. Form, a double 

 dodecaedron with trapezoidal faces. Colour, velvet black. 

 I do not believe this to be the melanite of European mi- 

 neralogists, but a fine specimen of the common trapezoi-
