Extract

Early in the year 1918 Mr. Atehur Russell picked up at the old antimony-lead mine at Glendilming in Eskdale, Dumfriesshire, Ipecimens of the antimony-lead ore Jound there, in which were small cavities lined with a drusy layer of mimlte crystals; these, being markedly deeper in eolour than the stibnite forming part of some of the specimens, belonged to a different species, and probably a sulphantimonite of lead. Mr. Russell blought some of the specimens to the Museum, and some of the small crystals were examined with the view of determining the species to which they belong.

page 354 note 2 A brief description of the mine is given by Robert Jameson in his book, 'A Mineralogical Description of the County of Dumfries,' Edinburgh & London, 1805, pp. 78-74 :-' About ten years ago, a vein of grey antimony ore was opened in Glendinning in Ekdale. The working was continued for tome time with much profit to the adventurers, but it has been lately given up, it as said owing to want of skill in the miners and energy in the proprietors. The vein traverses greywacke; but its extent, direction, dip, or width, I was not able to ascertain, as the workings had fallen in. The vein stones are quartz, and cale-spar ; the ores grey antimony, brown blende, filw-grained lead glazlce, and iron pyrites.'
