Gulf Stream are a powerful systole and cliastole in the sea. The 

 deep-channels of our fjords may be compared to veins that receive 

 the warm and salt water, the importance of which to the "organism" 

 of the Scandinavian Peninsula cannot easily be overvalued. 



III. Features of the hydrography of the coast sea. 



I have previously mentioned that the coast sea round Lofoten 

 and Vesteraalen is distinguished by great uniformity of hydro- 

 graphical conditions in winter. (5, p. 9 in my paper). In 1899 

 it was intended to examine this more closely, but the weather was 

 stormy throughout, and the little steamer we disposed of was rather 

 small. Several attempts were made to get outside the Lofoten- 

 Vesteraalen edge, but we were usually forced to turn back on 

 account of the bad weather. We succeeded however on a single 

 occasion (Mar. 22nd) to get so far out, that we had Gulfstream 

 water in the surface. 



About 60 miles in N. E. direction of Eøst (68^ 3' N., 10^ 

 0',5 E.) we had the following series of observations :

As I had no inversion thermometer affixed to my Petteeson's 

 water-fetcher, the 4 or 5 undermost temperatures cannot be impli- 

 citly relied upon. A little \varming during the upheaving through 

 a warm layer of several hundred metres is scarcely to be avoided
