 that this especially arctic character of the fauna is 

 maintained by the continual migration of arctic 

 species along with the arctic current indicated by 

 the depressions in the lines of equal temperature.

 not met with beyond its limits, owing doubtless to 

 the entire banking in and disappearance of the cold 

 water, and the obliteration of the arctic current 

 as such at the western opening of the channel 

 between the F&roe banks and the Hebrides.
