Scotland in a N.E. direction from Dumbarton. This conglomerate 
boulder, 5 J x 4J x 4 feet, had its corners well rounded. The nearest 
point to the parent rock in situ , would be at or near Callander, a 
distance of about 40 miles, in a direction about N.W., with several 
ranges of hills and valleys intervening. 
6. Mr Melvin, at Eatho Eailway Station, drew the Convener’s 
attention to the greenstone rocks there, how they are well rounded 
and smoothed on their sides facing the W. whilst on their sides 
facing the E. they were rough. 
He also pointed out how, on several of those smoothed surfaces, 
there are numerous striae and ruts running in a direction W.N.W. 
and E.S.E. (magnetic). 
Portions of these smoothed and striated rocks are covered by 
boulder clay or till, containing many small boulders and hard 
pebbles, which, by passing over and pressed down on the rocks, 
might have produced both effects. 
A number of large trap boulders were lying about. The largest 
examined, weighing between 2 and 3 tons, has horizontal striae on 
its side, which faced JST.N.W. These striae might have been formed 
by a force coming in a direction from W.N.W. and striking 
obliquely on that side of the boulder. 
This locality is at a height of from 180 to 190 feet above the 
sea.

Lowlands. 
In April 1880, whilst there was still so much snow on the High- 
land hills as to render explorations on them impossible, the 
Professor went to Dumfriesshire, having received notice of two 
boulders among the "Wanlockhead hills. 
(1.) The first he examined, called “ The Crooked Stone,” lies in 
a field on the right bank of the Clyde, about 3 miles above Elvan- 
% 
foot Station. The stone protrudes above the surface about 5 feet. 
Its width is nearly 5 feet ; its thickness about 1 \ feet. 
It is on a knoll projecting somewhat above the adjacent river- 
terrace.
