of Edinburgh, Session 1880 - 81 . 273 
col between Ben More and Am Runican (2800 feet) were 
seen. 
Ninth Day. — Went over Ben Vorlich , then over Stuck a Ghroin, 
Meal Odhar , to Callander. No boulders. 
Tenth Day. — From Callander over Ben Ledi (2882 feet) ; a hill 
ridge to Ben Vane, and down to Strath yre. No boulders , except 
some of gneiss near Callander. (On three of these days Professor 
Heddle was alone, on the others he was accompanied by a party of 
never smaller than four. The sides and ridges of the hills were 
swept by binoculars.) 
Professor Heddle’s notes next mention his return to Arrocliar, 
and on the first day ascending the Cobler (2400 feet), making the 
circle of its summit, and descending to the col between Ben Narnan 
and Beinn Ime (3318 feet), and returning by the valley between 
Ben Narnan and the Cobler. He observed glaciation (ill-defined) 
passing north-eastward. There were a few rounded blocks of Syenite 
lying on the col, which seemed to have been moved in a north- 
easterly direction, from veins of that rock in the col. 
On the following day he ascended Ben Narnan , through and by the 
sides of what he terms a “ Cradle Cup,” to its summit, and then 
down to the col between it and Ben Ime, over its summit to the 
col between it and the north hill (name unknown), down by 
Choiregrogain and back by Glen Loin. Boulders of the same 
Syenite were seen on several parts of Clioiregrognain. Several 
veins or dykes of this Syenite were found, especially a very large 
one protruding from the north shoulder of Crons (2785 feet). 
Assuming that the boulders came from these dykes, they had by 
some agency been transported eastward. 
The “ Cradle Cup,” lying between Crois and Ben Arnan, is 
described as “ an elevated and confined little valley,” wdth a rocky 
dam, which if neve was formed there, might have retained it long 
enough to allow of it being converted into ice, supposing the 
climate to have been suitable. Hot even in the contracted portion 
of valleys, is there so marked an amount of grinding, grooving, 
and polishing seen, as was seen upon the inner side of the rock 
dam of this “ Cradle Cup.” These evidences of ice action, at 
an elevation of only 1500 feet above the sea, are all the 
more remarkable, on account of the total absence of glaciation
