Tuesday, 9th August 1870. 
This morning we were joined by Mr. Archibald Gibson and 
Mr. J. J. Thomson. We had three conveyances, which started 
at 8.30 a.m. for the pass over to Glen Lyon. We visited Larig- 
an-lochan and the rocks above it where Woodsia hyperborea was 
said to exist still. It used to abound in that locality, but we 
looked in vain for the plant to-day. 
We then ascended the hill to the east and pass to Ben Lawers ; 
walked round on its northern side to Ben Lawers. 
We saw Aldsine rubella, Erigeron alpinus, Gentiana nivalis 
(some quantity), M/yosotzs alpestris, and many other alpine plants. 
We then ascended to the top of Ben Lawers, and had a 
glorious view, the day being clear and warm. On the summit 
we gathered Draba rupestris, Saxifraga cernua, Polypodium 
alpestre, and other alpine species. 
Descended to Carnic about 6.30 p.m., and returned to Killin.

This morning at 8 o’clock the party proceeded in two convey- 
ances to Cherai, at the foot of Meall Ghaordie. The partyascended 
to the summit of Meall Ghaordie, gathering a few ordinary alpine 
plants on the way. The day was very hot and oppressive, and 
water was deficient. A quantity of tea was taken up the hill, 
which proved very refreshing. On reaching the summit the 
party descended on the side of the mountain next to Glen Lyon 
and a farmhouse called Stoneriach. They gathered Cystopteris 
montana, Bartsia alpina,and many good alpine species, They
