the pbaenomena in the British Islands are concerned, " for 

 we can easily imagine, that when very different physical 

 featiires prevailed, and when lands now above the sea 

 were beneath it, cold currents may have extended very far 

 southwards of the Arctic circle, and have been inhabited 

 by species now restricted (through geographical changes) 

 to a less horizontal range " (Russia and the Ural moun- 

 tains, p. 551. note). Prof. E. Forbes considers the mam- 

 maliferous crag as belonging to this group.
