Abstract
The occurrence of glaucophane has not, I believe, been previously noted in Great Britain, and as it is a mineral of some interest, my friend Mr. Teall has suggested that a separate notice of it should be given. It would otherwise be naturally described in the Report on the Microscopic Structure of Anglesey Rocks to be presented to the British Association at their forthcoming meeting.
