A specimen of crystallised quartz and albite has recently been acquired for the British Museum which has a few isolated crystals of this rare mineral dispersed upon it. Conclusive evidence that the specimen comes from Cornwall is supplied both by the appearance of the quartz and albite and by the presence of the clay-slate with which they are associated.
The mineral monazite or Turnerite has hitherto been discovered in few localities and never in the British Isles. Anatase, however, is mentioned in Greg and Lettsom (Manual of the Mineralogy of Great Britain and Ireland, p. 363) as occurring at Tintagel and near Liskeard in Cornwall ; and it is just possible that crystals of monazite may have been mistaken for anatase.
