1. Dr Balfour read an account of a botanical trip which he had 

 made with some of his pupils to CI ova, Glen Isla, and Braemar, in 

 August last. Dr B. alluded in an especial manner to the alpine 

 Flora of the British Isles, the Scandinavian type of Professor E. 

 Forbes ; and illustrated it by a complete series of specimens, arranged 

 according to the Natural System on pasteboard, so as to be seen at one 

 view. He noticed Professor Forbes' theory, as to the mode in which 

 the plants migrated at the Glacial Epoch. He also alluded to the 

 geological nature of the district visited, which is the richest in Britain 

 as regards alpine species, and the character of the Flora on the dif- 

 ferent kinds of primary rocks, especially granite and mica-slate. 

 Specimens of the rarer species collected during the excursion were 

 exhibited, among which the following are interesting as having been 

 found in new localities, or re-discovered, in old ones : — Carex rupes- 

 tris, abundant in Glen Dole, the specimens being unusually large ; 

 Poa Balfourii, near the falls of the Whitewater, and also in Glen Isla, 

 and on Lochnagar ; Poa coena, in Glen Isla ; Poa laxa, and the 

 variety flexuosa, of Parnell, Lochnagar, and Glen Dole ; Luzula
