The author expresses belief that the phenomena may find explan- 
ation in the recognition of two movements, — one outward from 
Ben Nevis as a centre, the other a force travelling from the W.N.W. 
or KN.W. (Eighth Report, p. 21). 
Notes on boulders, situated to the west of Fort-William, by Mr 
Colin Livingston, teacher of public school, Bort- William. 
The author enumerates boulders and striated rocks on west side of 
Ben Nevis, and expresses a confident opinion that two glaciers existed, 
the one descending Glen Nevis, the other Glen Spean and Glen More. 
He refers to immense mounds and ridges of detrital matter, 
(having animperfect stratification) towards Inverlochy and Torlundy, 
— such as might have been produced, if it fell from some height 
(Eighth Report, pp. 23, 27). 
6. Since the time when Mr Livingstone’s Notes (given in the 
Eighth Eeport) were framed, he has made a further inspection of the 
hills to the W. and S.W. of Ben Nevis, and has communicated to 
Convener the following additional facts : — 
Stoh Ban, reaching a height of 3274 feet above sea, is situated 
west of Glen Nevis. It is composed of quartzite, which accounts for 
its Gaelic name of White Pin. Boulders of this rock are found to 
the eastward, on various parts of the west slopes of Ben Nevis. 
Another hill of interest is Mulloch-Nan-Coirean,^^ 3077 feet, 
having a rounded top of red granite. On its top there is a slab of 
mica slate. How it came there, Mr Livingstone says is a mystery. 
He admits that mica slate rock exists in large quantities towards 
Sghor Challum, a hill 1823 feet, situated to the west. But he sees 
the difficulty of conceiving that any glacier could have brought it. 
On the same hill there are boulders of micaceous gneiss and 
quartz. The quartz boulders, he says, may have come from Stoh 
Ban ; the birthplace of the gneiss boulders is (he says) uncertain. 
7. Notes on Ben Nevis and Craig Dhu, by Professor Heddle of 
St Andrews, were sent to Committee. He expresses an opinion 
that a glacier swept down Glen Nevis, even overtopping a hill of 
3077 feet. He also suggested the probable existence of another vast 
glacier cradled in the gorges between Aonach Beg and Aonach Mor. 
8. Ben Nevis. — Convener ascended to top, by a path leading 
up the N.W. side of hill. Enormous boulders of grey granite lie 
on N.W. slopes. A few on each side of path were measured, and gave
