hill, but I will confine myself to . the most important of those 

 noted on the 18th, my research on the other days being very 

 much confined to HepaticcB. 



" I may add that the season was a very late one. I have 

 never seen so much snow lying on the. hills in July during all 

 the years I have wandered over them. In the Glen Lochay 

 district I crossed hundreds of acres of snow, the patches being 

 far too large to walk round about, and some of the fissures 

 showed a thickness of not much under 100 feet, and the 

 glissading down some of the patches was as pleasing an ex- 

 perience as the walking up others was laborious. There were 

 a few pretty large patches on Ben Laoigh, which added very 

 much to our knowledge of the conditions under which alpine 

 plants exist and flourish. To see the alpine form of Caltha 

 minor in flower within three feet of the snow, and in water 

 at a temperature of 34°, with the mountain still ice-bound 

 about six inches below the surface, is interesting in the extreme. 

 Let me now speak of the plants I saw, and try to give some idea 

 of their condition —
