THE VOYAGE OF H.M.S. CHALLENGER 



undigested, and assuming this, it is possible that some of the small-seeded plants reached 

 the islands through seminivorous birds carried thither by violent storms. The following 

 classification is only offered as a possible solution of the question of transport for each 

 species. Other natural means of dispersal, such as winds, have not been considered, 

 because the object was to bring into prominence what probably might be effected by the 

 ocean and birds alone.
