This specimen shows a variety of faces depending on certain laws of increase and decrease, and seems more regularly forming the metastatic within, where it abounds with pyrites, than externally. This serves tos how that crystallization may continue while one substance has another within it. The pyrites, from their colour, as well as form, should seem to hold copper as well as iron.
