of Scotland the rock was found in situ. Mr Macdonald replied, 
— “ The light-coloured pinkish granite in the British Linen 
Company’s Bank came from the hill of Correnie in Aberdeen- 
shire, not far from Kemnay. It was cut from boulders. But 
similar rock is to he had quite near. Bock very much the 
same appears about Kincardine O’Neil, in Deeside, and also 
about Ballater and Braemar. A similar stone is found at 
Beaufort, county Mayo, and most likely in other parts of 
Scotland and Ireland. 
“ Your boulder is very much akin to all these rocks ; perhaps 
a little closer in the grain, but substantially the same. 
“ Many of the ocean-worn beach stones all along the coast 
to the south of this, are of the same granite as your boulder, 
or very much like it. 
“ I cannot lay my hands on a specimen sent to us, some 
years ago, from the Island of Uist; but if recollection hears 
me out truly, granite very much of the same character is to 
be got there.” 
Coldstream . — At the Hirsel (Earl of Home). About 120 feet above 
sea, boulder of white chert about 4 feet square, but very rough 
and irregular in shape. Found in a bed of gravel in making 
new avenue from Hirsel Policy to Coldstream. No rock of 
this nature known on north side of Tweed. It occurs at two 
or three places along the south of the Tweed, viz., at Carham 
and Nottylees; places bearing W. by S. from boulder, distant 
about 3 miles, with Tweed valley intervening. 
As rock composing boulder friable, and its shape very angular 
and ragged, it could not have been rolled or pushed to its 
present site, nor could have been thrown down from any great 
height. Probability is, that when detached from parent rock, 
it fell upon ice, which floated it across valley. 
Dunse . — On farm of Cockburn, a boulder of mica- schist well 
rounded. Is from 2 to 3 feet in length and breadth. An 
erratic from the Highlands of Scotland, and must have travelled 
at least 100 miles across many valleys and ranges of hills. — 
(First noticed by Mr Stevenson of Dunse.) 
Foulden . — Several small boulders of coarse sienite (lying on old 
red san Istone), composed of red felspar, black hornblende, and
