The specimen was found near Wanlockhead, Dumfriesshire, in 1872, by Andrew Gemmell, miner, who unfortunately broke up the piece, and disposed of the fragments to different parties in the locality. Mr Dudgeon was enabled to get possession of all the fragments, and has restored the mass to its original form. The specimen is a very interesting one, being the largest known piece of auriferous quartz found in Scotland; and Mr Dudgeon thought it would interest the fellows of the Society to exhibit it at the meeting before placing it in the Museum of Science and Art, which has now been done with the consent of the different owners.
