On some remarkable composite crystals of copper pyrites from Cornwall
Published online by Cambridge University Press: 14 March 2018
Extract
During a recent visit to Cornwall the attention of Professor Lewis was directed by Mr. James Wickctt to some composite crystals of copper pyrites recently found in one of the deep mines in the neighbourhood of Redruth. On the specimens acquired by the Cambridge Museum about thirty crystals show this composite growth, which causes the crystals to resemble ill-developed pentagonal dodecahedra of iron pyrites.
