Switzerland, with the liverwort Anthelia furatzkana forming the 
first coloniser of the snow-washed soil, accompanied by the 
characteristic Gnaphalium supinum, and the orange lichen Solorina 
crocea. The “ Suxifraga cernna corrie” proved most interesting and 
during the descent Professor Balfour pointed out an extensive 
association of Funcus trifidus competing with the intruding Alche- 
milla alpina pasture association. The more interesting arctic-alpine 
species, of which a considerable number were found in flower, will 
be alluded to in Mr. Druce’s account of the floristic results of the 
expedition. After reaching the summit most of the party explored 
the cliffs above Lochan ’a Chat, and crossed the extensive and 
partially denuded peat-deposits to the east of the summit, gathering 
Cornus suecica in the Vaccinium Myrtillus-Empetrum nigrum asso- 
ciation at about 3,000 feet. The whole party met at the Lawers 
Hotel for tea between 5 and 6 o’clock. Professor Massart obtained 
a number of excellent photographs of the arctic-alpine associations. 
On August 18th the early steamertook the party to Killin pier, 
and thence by train through Glen Ogil and by Loch Earn to 
Callander. After an early lunch the party drove to the Trossachs, 
and after walking a little way along the shores of Loch Katrine, 
turned back through the wood to Loch Achray. This wood 
proved to be a very beautiful and typical example of a Quercus 
sessiliflora wood with heathy ground vegetation, a type so common 
on the old siliceous rocks of northern and western Britain. A few 
plants belonging to the non-heathy type, e.g., Scilla non-scripta, 
occurred hereand there. On the cliffs to the north the characteristic 
zonation of oak below and birch above was well seen. The party 
returned to Callander, where the night was spent. 
On the morning of August 19th the party travelled to Glasgow, 
and after a brief view of the Town Hall, etc., went straight to the 
Botanic Garden, where Dr. Lawson kindly showed the well-known 
moss-house. The Botanical Institute was afterwards visited, and 
then Professor Bower, who was not fully recovered from a sprained 
knee and came over from his house on crutches, entertained 
the party to lunch at the Students’ Union. The afternoon was 
spent at the Glasgow Exhibition where the historical and particu- 
larly the “ prehistorical” section greatly interested the party. In 
the evening the party left for Greenock where they embarked for 
Dublin. 
On the morning of Sunday, August 20th, after a smooth passage, 
the party arrived in Dublin and were met on the quay by Mr. Lloyd 
Praeger, who had organised with his usual care and thoroughness 
the Irish portion of the tour, and who acted as guide throughout 
Ireland. The Botanic Garden of Trinity College was visited in 
the forenoon under the guidance of Professor H. H. Dixon, while 
in the afternoon the Glasnevin Gardens were visited by most of the 
party, a few members going instead to the sand dunes and salt 
marshes of the North Bull. 
On August 21st the party left Broadstone station by the west- 
bound mail at 7 a.m., and travelled right across Ireland to Clifden, 
Co. Galway, where the afternoon was spent on the hillsides on the 
north of Clifden Bay. The constant association of Ulex Gallit, 
Dabeocia polifolia and Erica cinerea in clumps scattered in the
