Mica Schists of the Schuylkill River. — Theodore D. Rand pre- 

 sented specimens of mica schist from the river road near Strawberry 

 Mansion, Fairmount Park. The nodules resemble very imperfect 

 andalusite crystals, but appear to be almost wholly quartz with a 

 little kyanite or sillimanite, resembling closely those described by 

 the late Dr. George H. Williams, in the Fifteenth Annual Report of 

 the United States Geological Survey, p. 665, as occurring on Sligo 

 Branch (probably Fairfax Co., Va.) and as suggesting contact 

 metamorphism of included fragments.
