90 Charles Maclaren, Esq., on the Existence of 



may have extended as far south as the lower, or still farther, 

 is probable enough. The surface under c is much broken, and 

 something like vestiges of terraces may be found on it. The 

 greater height of the hill here would render the torrents, 

 which are very numerous, more destructive ; and it is possible 

 tliat the lower moraines were chiefly formed from the wrecks 

 of the upper. The hills on the west side of the loch scarcely 

 exceed the height of a in figure 1, and they present no dis- 

 tinct traces of lateral moraines. 



Terminal Moraines, 



The projecting 

 ton ue of land at 

 Row, iy fig. 5, is about 

 a mile in length at 

 low water. It ter- 

 minates in a point, 

 marked by a pole 

 or beacon, and its 

 breadth at the other 

 end where the road 

 crosses it, near the 

 hill foot (at h o, fig. 

 1) is 600 feet. Its 

 elevation above the 

 high tide level is 40 

 feet. There is a 

 point at Roseneath, 

 exactly opposite {h in fig. 5), whose breadth is greater, and 

 its length smaller, but its height and materials the same. The 

 space of open sea between the two points, at low tide, I esti- 

 mated at 800 feet, and a shoal extends from the one to the 

 other, upon which there is only 4 fathoms of water, while the 

 depth a little below is 9 fathoms, and a little above, 18. 



The small diagram P in the corner of figure 1, shews the 

 form of Row Point on the cross section about midway between 

 its extremities. The south side g h slopes very gently, while 

 the north side e/is highly inclined. A drab-coloured clay is 

 seen on the west side, and seems to form the basis of the
