wegian coast. The maximal temperatures oft' the North Cape are 

 approximately the same as those olf the south coast of Iceland, some 

 8" of latitude to the south, and the mean maxima in the German 

 Bi^ht are again similar to those which we tind some 8 ' farther south 

 in the open ocean. 



In Fig. 9 we have a similar chart of the mean minimal tempera- 

 tures : and here we have an almost precisely contrary distribution to

that of the preceding figure : that is to say, the oceanic isotherms 

 are strongly bent to the southward, off our own west coast and the 

 west coasts of the Continent. But together with this marked influence 

 of the proximity of land in lowering the winter temperature of the 

 sea, w^e also see very clearly the influence of the Great Atlantic, or 

 " Gulf Stream," Current, whose warm waters proceeding on their 

 north-easterly course towards the Norwegian coast constitute a region 

 of relatively high minimal temperature ; until we come still nearer to
