of a mineral occur at Tower Hill, in Cumberland, which we

‘mostly massive, having generally an uneven cross fracture, 
though sometimes it is nearly smooth. The colours are vari-

ot blackish ssrpcoliae running through it, occasionally, in 
various directions. It is both Pas and in long acicular 
prisms, which are generally disposed in a radiating form. 
Its masses possess a highly er eedlins structure, and very
