&go. The nugget in question is larger by 5 grains 
than the largest hitherto found in Sutherland —viz, : 
the Rutherford nugget discovered in March last: and 
this circumstance—taken in connexion with the other 
facts mentioned in this section (\dz.) affords the 
strongest encouragement to gold-prospectors to direct 
their attention to the Highland glens of Perthshira 
The “Manual” also mentions, on the authority of 
Professor Tennant, gold as accompanying cubic 
Pyrites in Perthshire. 
In Murchison's “ Siluria ” (3d edition, p. 478^ 
foot-note t), it is stated that, near Locheamhead, a 
metalliferous veinstone, on property belonging to the 
Marquis of Breadalbane*, is slightly impregnated 
with gold, which occurs in a “ gossan,” contiguous 
to the junction of Trap with crystalline limestone 
and schist, and is associated with arsenical pyrites 
and lead ore. 
The late Marquis of Breadalbane seems not only to 
have taken an interest in the occurrence of gold 
v\dthin his territory, but to have possessed various 
specimens thereof, which he showed to Professor 
Tennant of London, Sir James Simpson of Edin¬ 
burgh, and other scientific men well known at the 
present day. Professor Tennant [who holds the 
Chair of Geology and Mineralogy in King’s College, 
London, and who is a Mineralogist of much experience] 
—mentioned in a discussion on gold-mining at the 
Society of Arts, in May, 1862, that he “ was stopping 
at Lord Breadalbane’s last year, and in looking round 
the neighbourhood, he found quartz -^ith gold and 
iron pyrites in it. But it would probably cost 30s 
for each 20s worth obtained ” [to work it]; “ which 
as a commercial speculation might not appear a 
desirable one to all parties !” This last remark 
applies to quartz-crushing, and the subsequent separa¬ 
tion of the gold by amalgamation or other complex 
* The fcircumstauces under ■which iruetalliferous veins occur in 
Breadalbane are fully described in an Essay ** On the Mines and 
Minerals of the Breadalbane Highlands” by F. Odernheimer— 
published in the‘‘Prize Essays and Transactions of the 
aad and Agricultural Society of Scotland ” for 1841, p. 541.
