[CHAP. vni. 



the remarkable conditions of climate on the coasts 

 of Northern Europe are due in a broad sense solely 

 to the Gulf-stream. That is to say, that although 

 movements, some of them, possibly of considerable 

 importance, must be produced by differences of spe 

 cific gravity, yet the influence of the great current 

 which we call the Gulf-stream, the reflux of the 

 great equatorial current, is so paramount as to reduce 

 all other causes to utter insignificance.
