on limestone, interbedded with the old red sandstone, at Dalroy, 
on the Nairn. It is composed of ordinary gneiss. 
6. Conglomerate boulder in a field, a little to the N.E. of “ Tom 
Riach” boulder, measures 95 feet in circumference, and 35 feet in 
length. It lies about 350 feet above sea-level. Same kind of con- 
glomerate as the “Torn Riach/’ which would show that it came from 
the S.W. 
7. Conglomerate boulder (same as other), lies in the bed of the 
River Nairn, to the East of Daviot House. Measures about 6x7x8 
feet. 
8. Four conglomerate boulders, same as last, on the moor, north 
of Nairnside School House, at a height of 590 feet above sea-level. 
One measures 14x8 feet, one 13x15 feet, one 9x9 feet, and 
one 9x8 feet. These may have come from west. They do not 
rest one upon the other. 
9. In Cran-More Wood, Nairnside, there is one boulder measur- 
ing 9x6x3 feet, which is stratified conglomerate, similar to that 
found at Eailie, about 5 miles to the west. This boulder lies at 
a height of 600 feet above sea-level. In the same wood there is a 
gneiss boulder, 5x6 feet, slightly rounded, and resting on old red 
sandstone. 
10. Conglomerate boulder, on south shore of Loch Duntilchaig, 
opposite Achnabat, a few feet above the loch and 720 feet above 
sea-level. It measures 4x5x3 feet. There are several others of 
the same rock lying along the shore of the loch. These can easily 
be identified with the rock on JDunchae, which is about a mile to 
the W. There is no other similar rock in the whole neighbour- 
hood. It is composed not of rounded pebbles, but of thin pieces of 
rock. 
11. Granite boulder on the west shoulder of Dalcromlin Hill, 
which lies S.W. by S. of Inverness. This boulder rests on con- 
glomerate rock, 1200 feet above sea-level, and measures 5x3x3 
feet. 
12. Clach-an-abau is a conglomerate boulder, lying in Petty Bay, 
to the E. of Inverness. It was moved by the tide. The waters 
round it had frozen, and thus served as a means of floating it. It 
is not large, perhaps about 4x3 feet. The underlying rock is old 
red sandstone.
