have not been able exactly to identify this rock, hut from 
descriptions in niineralogical hooks, I am of opinion that it is a 
diorite. The stone has every appearance of being waterworn and 
rounded, hut whence it came I cannot say. 
20. One of the stones in the “ circle ” at Culloden Railway 
Station is a serpentine. There is serpentine in Glenurquhart, which 
is about 12 or 14 miles W. from Inverness. I do not think the 
builders of these circles would have gone so far for building 
material. 
21. A friend of mine in Glenurquhart tells me that there are 
granite boulders in that district, differing from all the granites 
surrounding the Glen. He is investigating the matter, and I expect 
to have exact information regarding them soon.

1. On the south slope of Tullocli Hill, the following boulders 
occur : — 
(1) At the height of 550 feet above sea, an irregularly rounded 
boulder of granite-gneiss, supposed to he one of those mentioned by 
Mr. John Campbell in Frost and Fire , vol. ii. p. 152, as consisting 
“ of a peculiar kind of pink granite, resting on slate,” and of which 
he gives a diagram at page 167. 
Its girth is 29 feet; greatest length 11 feet; height 7 feet, and 
breadth 7 feet. Its major axis is U.U.W. and S.S.E., with sharpest 
end to E. The felspar in the boulder is pale red, and the mica so 
arranged as to produce a laminated appearance. 
(2) About a quarter of a mile S.W. of Ho. 1, on Upper Docharty 
Farm, at 400 feet above sea, another boulder of same rock 8x5x5 
feet; and major axis U.U.W. and S.S.E., with sharp end to west. 
(3) To H.W. of Ho. 1 boulder, at a height of 620 feet above sea, 
a flat block of mica schist, 11x7x2 feet; major axis W. and E. 
The west end pointed, and appears as if scoured by running water. 
The upper surface is scored by natural ruts, grooves, or striae, 
2 and 3 inches broad, and from J to \ inch deep. These run in a
