Note, — In support of the theory which I have put forward m 

 my introductory remarks, namely, that in the higher latitudes 

 visited by our expedition the duration of the sun's power is too 

 brief to enable flowering plants to ripen their seeds, and that m 

 fact no annuals occur, I may mention that a large series of appa- 

 rently ripe seeds, taken from almost all the species occurring at 

 the stations visited, has been submitted to Messrs. Moore and 

 Burbidge, of the GhiMievin and College Botanic Gardens, Dublin, 

 and that their efforts to obtain even a single seedling were 



unsuccessful.
