examination of every bum in the district, I failed to find any of the 
blue clay on the lower ground. This I take to be an additional 
proof of the easterly flow of the ice. 
As far as the boulder evidence in this district goes, it proves con- 
clusively that the ice-flow was from the W., or a little to the S. of W. 
All along the south shore of the Moray Firth there are scattered 
boulders of conglomerate, hornblende, and dirriemore (besides 
other) granites. In the neighbourhood of Inverness, these would 
indicate a drift from the fST.fST.W. and one from the S.W., both 
tending E., or a little to the N. of E. The boulders of hornblende 
might have come from the N.W. The only place where I have 
seen hornblende in situ in the neighbourhood of Inverness, near 
which are found numerous boulders of that rock, is at Raven’s- 
Rock near Strathpeffer.

Mr Milne Home , Chairman of the Boulder Committee , after 
presenting the preceding Report , made the folloicing remarks : — 
I may explain that, to save the time of the meeting, and also to 
afford to members information regarding the operations of the 
Committee during the past year, copies of the Eeport were 
circulated with the billets for the present meeting ; — and for the 
same purpose, as Convener of the Committee, I now proceed to give 
an abstract of the chief features of the Report. 
I. Boulders in Nairn, Moray , and Banffshire. 
I begin by alluding to the boulders in these counties, because 
the notes applicable to them are in some sense a continuation of 
the part of last year’s Report applicable to these counties. 
In these counties there are two classes of important boulders, — 
Granites and Conglomerates. 
Of granites there are four kinds, distinguishable by the ingredients, 
and by the different districts where their parent rocks are situated. 
There are, First, the boulders, consisting of a very peculiar granite, 
with lenticular pieces of dark mica, arranged in pretty regular layers, 
through a pinkish mass, giving to it some resemblance to a stratified 
deposit. The granite of these boulders has been identified by Mr
