together like sepulchral tumuli. ‘These mounds, composed of un- 
stratified gravel and boulders, Dr. Buckland says cannot be referred 
to the action of water, as they are placed precisely where a current 
descending from the adjacent high lands would have acted with the 
greatest velocity ; and they exactly resemble some of the moraines 
in the valley of the Rhone, between Martigny and Loek. ‘The vil- 
lage of Amulrie is considered by the author to stand on a group of 
low moraines ; and the road for two or three miles from it, towards 
Glen Almond, to traverse small moraines or surfaces of mica slate, 
rounded by glaciers. A few conical moraines appear also on the 
high lands between Glen Almond and Crieff. 
Proofs of Glaciers in and near Strath Karn.—This part of the val- 
ley of the Earn is flanked irregularly with ridges and terraces of 
gravel, the detritus of moraines ; and on its north side, in the woods 
adjacent to Lawers House, near Comrie, hard slaty rocks of the Devo- 
nian or old red sandstone system have been rounded and striated. At 
the west end of Comrie, near the bridge, blue-slate rocks have been 
also rounded and guttured. 
Evidence of Glaciers near Comrie.—In this district Dr. Buckland 
tested the value of the glacial theory by marking in anticipation on 
a map the localities where there ought to be evidences of glaciers 
having existed, if the theory were founded on correct principles. 
The results coincided with the anticipations. On a hill above the 
gorge, called the Devil’s Cauldron, near Fentallich, are rounded 
surfaces of greenstone, partially covered by moraines ; and at Kena- 
gart, also immediately above the Devil’s Cauldron, is a small cluster 
of moraines, easily separable into lateral and terminal. ‘Two miles 
up the valley a medial moraine forms a ridge on the level ground, in 
front of the confluence of Glen Lednoch and Glen Garren. The farm- 
house of Invergeldy is stated to stand on the detritus of a moraine, 
and the glen descending to it from Ben-na-cho-ny to be partially 
obstructed with moraines. The surface of the granite at Invergeldy, 
-which supplied the stone for Lord Melville’s monument at Crieff, is 
rounded and mammillated, but too much weathered to present a 
polish or striz. On a hill of trap, however, half a mile south of the 
farm of Lurg, there is a distinct polish, striated in the direction 
which a glacier descending the subjacent valley would assume. In 
Glen Turret, on the shoulder of the mountain immediately above the 
south-west extremity of Loch Turret, a very deep ravine intersects 
a vast lateral moraine, which Dr. Buckland shows must have been 
lodged there whilst the Loch was a mass of ice, and the valley above 
it filled with a glacier more than five hundred feet above the present 
level of the lake. At the falls of the Turret, at the lower extremity 
of the gorge, is an extensive lodgement of moraines; and-at the 
upper end, on the left bank of the Turrets near a gate which crosses 
the’ road, the slate-rocks are polished and furrowed; and at both 
these localities Dr. Buckland had anticipated that glacial action 
ought to be found.

Loch rounded and furrowed surfaces and portions of lateral mo--
