The prisms in this specimen are four-sided, and the two opposite sides that are parallel to the laminæ are broader than the other two; they are terminated by a four-sided pyramid with rhomboidal faces, which in some crystals are truncated at the apex. They line an irregular cavity in a fragment of a Basaltic column from the Giant’s Causeway. I was favoured with it by John Templeton, Esq.
