Notes on the occurrence of wulfenite at Brandy Gill, Cumberland, and of leadhillite at Drumruck mine, Kirkcudbrightshire

Arthur Russell
1936 Mineralogical Magazine and Journal of the Mineralogical Society  
In October 1875 the late J. G. Goodchild recorded his then recent discovery of a mineral which he stated 'he believed' to be wulfenite and which he had found on an old mine dump near Carrock Fell, Troutbeck, Cumberland. One specimen only was, I believe, found by Mr. Goodehild, and this he presented to the Carlisle Museum, where it has been seen by myself, the label bearing the more precise locality of Brandy Gill.
