of Edinburgh , Session 1879 - 80 . 
picked up two pebbles of red granite about the size of a ben’s 
egg. Thinking it curious that granite should be found there, he 
laid the pebbles aside and kept them for some time, but they had 
since been mislaid. 
Having been told that a number of large pebbles of various kinds 
were seen at the west end of the island, on the beach, I went there, 
and found numerous pebbles of granite (both red and grey), gneiss, 
quartz, and hard Silurian rocks. 
On the highest part of the island (which is 182 feet above the 
sea), and on portions facing the N.W., the rocks have been well 
planed down to even surfaces by some agency from the west. But 
no striae were observed. 
4. A short time ago I went, on the invitation of Captain John 
Macnair of Edinburgh, to examine two boulders lying at the side 
of the Water of Leith, on the farm of Whelpside, near Kaims and 
Dalmahoy hills, about 9 miles S.W. of Edinburgh. One boulder 
was 13 x 10 x 6 feet, and the other 10 x 8 x 5 feet; but the depth 
of either could not be well ascertained, being deeply sunk. They 
were both of them a hard porphyry, containing minute crystals of a 
black mineral like hornblende, in a basin of white felspar. The 
longer axis of both was E. and W. They were covered with striae, 
long and deep, running also E. and W., and indicating a movement 
over them from due west. 
I ascended the Kaims hill, situated about a mile to the N.W. of 
the boulders, and found its west side swept bare, with numerous 
large fragments of the rock of the hill (a hard sandstone) strewed 
over its eastern slope. 
On my way back to Edinburgh I examined the whinstone quarry 
of Ravel rig, and found, on the natural surface of the rock composing 
the hill there, numerous examples of ruts and scoopings, all 
indicating an agency which had passed over the hill from due 
west. 
Kirkcudbrightshire. 
Large rounded fragments of granites and syenites are abundantly 
scattered over the Stewartry, and so arranged as to indicate that 
they have been dispersed by a force proceeding from the N.W. —
