Extract

During the last summer, whilst mapping the district between Nevin and Clynnog-fawr, I discovered the intrusion which is described in this communication. I can find no reference to it, either in geological maps of the Lleyn or in any geological literature, and conclude that the occurrence has not been placed on record.
