Proceedings of the Royal Society 
near Stornoway. On Stainchol shore the Professor found dolerite 
boulder containing Lahradorite. He states that the parent rock is 
situated^about fifty yards to H.H.W. {Sixth Report, p. 38). 
Judging from what is casually said by Dr Macculloch and 
Principal James Forbes, regarding boulders in Skye, they must be 
numerous and interesting. Thus Forbes refers to boulders '‘'•poised 
upon others, or fantastically balanced on the tops of elliptical domes 
of roclcs; ” and Macculloch says that the summits (on which some 
of the boulders stand) are not only hare, hut often very narrow, 
while their declivities are steep, and sometimes perpendicular. 
Macculloch confesses his inability to explain these phenomena. 
Inverness-shiee. 
Loch Nevis, on west coast. Several large boulders of coarse- 
grained granite seen near Inverie House, lying on slate rocks. 
On road towards Gussern, several boulders of interest pointed 
out to Convener by late Mr James Baird, the proprietor. 
At height of 360 feet above sea, and near sea-shore, rocks 
smoothed and striated from IST.W. by W. 
Two large boulders lie on side of a hill, which slopes down to the 
W.H.W. One of these, of elongated shape, has its longer axis 
N.W. and S.E. 
A large boulder, consisting of two fragments, pointed out by Mr 
Baird, in consequence of his believing that the boulder had been 
broken by falling from a height, and striking on the hare rock, 
where these fragments now lie. The two fragments are four or five 
feet apart. Whilst the opposing surfaces correspond in shape, they 
are so weathered, as to show that the fracture was not of recent date. 
At summit level between Inverie and Gussern, there is a horizontal 
terrace, facing the sea, and at from 400 to 500 feet above sea, with 
a number of boulders on it. 
At Invergussern, lower part of valley blocked by a huge gravel 
ridge, now cut through by river, quite in the position of a terminal 
moraine. But, being composed of nearly horizontal beds of gravel 
and sand, from 40 to 50 feet deep, more probable that it is a sea 
deposit, and that it for some time confined a lake; for on the 
sides of valley horizontal water-lines occur {Second Report, p. 164).
