3S4 NOTICE OF MARINE DEPOSITES 
XXVI, — Notice of Marine Deposites on the 
3Iargin of Loch Lomond, 
By Mr J. Adam son, 
(Read Mth December 182^.) 
to beauty or magnificence of scenery, Loch Lomond 
has many interesting features common to it with the other 
Scottish lakes which occupy the chasms of the great primi- 
tive mountainous district ; it is, however, more closely con- 
nected with a different set of hollows. It is the most cha- 
racteristic example of a group of long recesses which lie 
together, and nearly parallel to each other, but which, in- 
stead of following the direction of the mountain ranges, 
stretch almost perpendicular to it, generally cutting through 
the Transition and part of the Primitive rocks, together 
with the older members of the Floetz formation. All the 
others of those valleys are connected with the sea by means 
of the Frith of Clyde, and are partly filled with its salt 
water, and enlivened by its appropriate animals. There is 
reason enough to believe, that this was at one time the 
condition of Loch Lomond also; but at present, we find 
there, along with the Ocean's depth, only the remains of its 
inhabitants.
