“* After having obtained in Switzerland the most conclusive proofs, that 
at a former period the glaciers were of much greater extent than at the 
present ; nay, that they had covered the whole country, and had trans- 
ported the erratic blocks to the places where these are now found, it was 
my wish to examine a country where: glaciers are no longer met with, but: 
in which they might formerly have existed. I therefore directed my at- 
tention to Scotland, and had scarcely arrived in Glasgow, when I found 
remote traces of the action of glaciers; and the nearer I approached the 
high mountain chains, these became more distinct, until, at the foot of 
Ben Nevis, and in the principal valleys, I discovered the most. distinct 
moraines and polished rocky surfaces, just as in the valleys of the Swiss 
Alps, in the region of existing glaciers;.so that the existence of glaciers 
in Scotland at early periods can no longer be doubted. The parallel 
- roads of Glenroy, are intimately connected with this former occurrence 
of glaciers, and have been caused by a glacier from Ben Nevis. The 
phenomenon must have been precisely analogous to the glacier lakes of 
the Tyrol, and to the event that took place in the valley of Bagne.” : 
At one of the early meetings of the Geological Society of London, M. 
Agassiz read a paper, illustrating his views and their application to Scot- 
land. This was followed on the 4th of November by.a long. paper from 
Dr. Buckland, on the same subject, and which was concluded on the 
meeting of the 18th, but reserving its more minute details for a subse 
quent evening ; while Mr. Lyell has also commenced the reading of a paper 
“Qn the Geological evidence of the former existence of glaciers in For 
farshire.” Dr. Buckland, in his paper, gives a general account of his 
a in Scotland, and among the more remarkable parts of his com- 
' munication is the announcement that the traces of ancient glaciers. are. 
apparent in Crickhope Linn, in Nithsdale, Dumfriesshire, upon the rocks 
of Stirling and Edinburgh castles, and upon Corstorphine, the Calton, | 
and Law Hills, near Edinburgh. This theory, as applied to Scotland, ee 
- comparatively new ; and in the animated discussions to which it has just . 
given rise, has been combatied, or strictly scrutinized, by Messrs. Gree 
nough, Sedgwick, Murchison, Whewell, Phillips, and De la Beche. We 
have no doubt that the traces, as stated by the Professor, exist in all the 
above named localities ; but while such is the case, it becoties most 1™
