that the Hnes in the map are wrongly drawn, because had 

 there been many more stations the Hnes might have formed a 

 number of vortices, Hke those mentioned above, p. 282. How- 

 ever that may be, it is a fact that we fell in with a current 

 running south-west, in the midst of the water-masses following 

 the direction of the Gulf Stream towards the north-east, and 

 this singular circumstance may be dealt with in greater 

 detail. 



The section shown in Fig. 204 stretches from the Sargasso 

 Sea along: the track of the " Michael Sars " northwards to the 



Newfoundland bank

Newfoundland Bank. At Stations 64 and 65 the conditions 

 were uniform, resembling those found during the cruise from 

 the Canaries westwards (see Fig. 63, p. 84). All this part of 

 the Atlantic in and about the Sargasso Sea belongs to an 

 oceanographically homogeneous region, but at Station 66 we 

 suddenly met with very different conditions, for it was much 

 colder in all the layers above the deep water, and the salinities 

 were much lower. On proceeding farther north we again 

 found, at Station 67, the same warm and salt water-masses 

 as farther south at Stations 64 and 65. There was a decided 

 difference also as regards the pelagic flora and fauna, which 

 had a more northern facies at Station 66 than at Stations
