This is often found accompanying common Galena. It is externally known to Mineralogists by the peculiar small striated appearance which is attributed to the nature of the crystallization of the Antimony, and which seems to derange the primitives of Common Galena; so that one substance interrupting another may be recognized here; and perhaps in some other place we may be able to show something more important in the nature of the laws of mixed crystallization.
The specimen here figured was sent by my friend the Rev. J. Harriman. it seems to be less antimoniated toward the base, and somewhat resembling tab. 131.
