salinity at all depths is quite the most remarkable feature of the 

 section, indicating an unusually large proportion of water of Arctic 

 origin in the Norwegian sea. This water appears to be moving south- 

 wards in mid-channel, both at the surface and in the depth, a slight 

 weakening being apparent between 50 and 100 fathoms, where the 

 salinity rises above 35*1. On the western side the increase of salinity 

 is so slight as to make it doubtful if any northward movement is

taking place ; it seems more likely that the 3 5 "4 water observed there 

 in June is merely undergoing mixture with the fresher water, a view 

 supported to some extent by its steady temperature. A northward 

 movement is, however, apparent on the eastern side, where the 

 temperature is relatively high, and the salinity rises above 35"4. 



We may summarize these results as follows : — 



1893. — Both northward and southward moving streams strong. 

 The Norwegian stream occupied most of the channel in the inter- 

 mediate depths ; below it water was moving southwards, and on the
