The cases showing this, which are mentioned in the Keports and 
Abstract, are so numerous that they need not be particularised. 
Testimony to the north-westerly direction from which boulders 
in Scotland have been carried, is given by the following geological 
authorities — Professor Geikie {Abstract^ p. 841) ; Sir Eoderick Mur- 
chison {Abstract^ p. 795) ; Charles Maclaren {Abstract, p. 840) ; Eobert 
Chambers {Abstract, p. 876); J. F. Campbell {Abstract, p. 815); 
J. F. Jamieson {Abstract, p. 795) ; Professor Harkness {Abstract, p. 
797); W. Jolly {Abstract, p, 799); Mr Anderson Smith {Abstract, p. 
776); John Young (Glasgow University) {Abstract, p. 839); James 
Croll {Abstract, p. 841); T. Hay Cunningham {Abstract, p. 838). 
In the Lewis there are kaims or escars on a very large scale, — 
continuous for several miles, whose north-westerly direction, and 
numbers of boulders lying upon them, suggest the idea that they 
may be due to the same agency which has transported the boulders 
{Abstract, p. 820). 
2. But whilst a movement from north-westward is very general 
in Scotland, it is right to notice exceptional cases. 
In Loch Long and Loch Fyne there has been a movement from 
N. or H. by E. {Abstract, p. 774, 775). In Islay {Abstract, p. 806). 
Buteshire {Abstract, p. 791). 
In Morayshire and Elgin Mr Jolly points out two streams, one 
from 6° S. of west, — the other from 15° H. of west {Abstract, p. 799). 
In Perthshire {Dunkelcl) the direction of the strise on the 
rocks at a high level is from JST.N.W., — whilst at a lower level, in 
the same valley, it is from N.E. {Abstract, p. 857). In the Lewis a 
similar case occurs; — the direction of the movement at a high level 
being from W.N. W. ; and at a low level, in the same district, from W., 
or even W.S.W. {Abstract, p. 819). In Assynt, whilst the normal 
direction is N. 60° W., the direction changes to due north, caused (as 
Chambers supposes) by the interference of a hill {Abstract, p. 875). 
So also near Gairloch, whilst the normal movement is from 
W.H.W., as shown by boulders and stri93, there is a locality among 
the hills, where the movement is shown to have been from W.S.W. 
{Abstract, p. 861). 
Cases have already been noticed, where there are two sets of strise 
crossing one another. Thus in Morayshire {Abstract, p. 849) the 
H.W. striae are crossed by others of a later date coming from H. 
by E.
