minerals, never before recorded as belonging to the district, have 
to be added to the list, and one new to science.* I leave out for 
the present the mining districts of Wanlockhead and Leadhills, 
which have been long well known—they are the only important 
metaliferous mines in the district. The Blackcraig mine, near 
Palnure, which was worked for lead for a good many years, but 
lately abandoned, produced very fine specimens of Dolomite, some 
of the crystals being of a fine purple tint, probably derived from 
the presence of manganese. I found there some very remarkable 
forms of Iron Pyrites—forms I had never before seen. The Pibble 
mine, about five miles north-east of Creetown, was long worked 
for lead, and large sums have been expended in opening it up ; it 
has resulted in a heavy loss to the promoters ; the usual lead and 
other minerals are to be found amongst the old heaps, but no very 
striking specimens. At Lackentyre, up the valley of the Fleet, 
Gatehouse, there are the remains of lead and copper workings, 
long since abandoned. Wulfenite (molybdate of lead) is found 
there—the only locality in Britain for this mineral. There are also 
the other usual lead and copper minerals. Hematite mines exist 
near Auchencairn (not:now worked), and trials have been made in 
the neighbourhood for copper, which exists, but not in anything 
like paying quantities. The usual copper ores are found in the old 
heaps. Copper has been tried for about half-way up the west side 
of Cairnsmore; the working there appears to have been very 
superficial ; good specimens of Chalcoperite were found in the 
heaps. Several trials for lead were made some years since along 
the side of the Monypool Burn, near Creetown. The lead was 
not found in paying quantities, and they were soon abandoned. 
I was” fortunate to find there a thin veil of Kupfernickel and 
Arsenic. The only other places which I know of in Scotland 
where Kupfernickel has been found are Wanlockhead and Hiider- 
stone, in Linlithgowshire ; it was in the vein on the Monypool 
Burn I found the new mineral above referred to. Up the Kinharvy 
Burn, above Kinharvy House, one or two manganese minerals are to 
be found, and very good specimens of brown quartz ; Antimonite 
was said to be found near that locality ; I have looked for it very 
carefully, but never found a trace of it. Zircon also was said to be 
found in the Criffel granite ; Mr Copeland mentions he could never 
find it ; I have looked very carefully for it, and broken up many
