to as a species dependent for any future extension entirely upon 

 its increase at a single centre (the pine-forests of Kothiemurchus), 

 and quite independent of any accessions by migration. Another 

 class of illustrations was then brought forward relating to species 

 which have greatly increased under our own eyes. From being 

 regular birds of passage, these have invaded our northern areas, 

 aj^parently from different centres, ever increasing and pushing 

 forward. The Stock-Dove, Tufted Duck, Great Spotted Wood- 

 pecker, Hawfinch, Redstart, Starling, Goosander, and Ked-breasted 

 Merganser were cited as examples. A point deserving further 

 attention is, that extension of range of species as breeding species 

 in Britain does not depend upon the autumnal lines of migrations, 

 but upon the returning lines of spring migrations. Another 

 species which of late years has bred numerously in Scotland — the 

 Woodcock — was stated to have extended its breeding area recently 

 into the bleak, unwooded islands of the Outer Hebrides. This, 

 however, was not done apparently until the more sheltered birch- 

 clad glens and young fir and larch-plantations of the mainland 

 had received and cherished the earlier colonists of the species. In 

 conclusion, Mr. Harvie-Brown in his paper appealed to naturalists 

 to pay close attention to detail in recording the movements of all 

 living things, as important results might be reached even from 

 what might appear of little importance at the time.

Mr. George Horn exhibited a collection of Alpine plants from 

 the Andes. Among them were Luzula Alopecurus, Desv., Azorella 

 aretioides, Willd., Cerastium irnhncatum, H.B. 6: K., and species of 

 Valeriana and Alchemilla from the snow-limit ; also Astragalus 

 uniflorus, DC., gathered on Chimborazo, at an altitude of 15,000
