By comparison with M. Knudsen's chart of the surface- 

 temperature and sahnity in the sea between Iceland and the 

 Faeroes, 1895 and 1896 ^, it may also be seen that our surface- 

 temperatures in this sea in July 1900 was considerably higher 

 (one or two degrees) than in July and August, 1896. 



Our surface-temperatures in the sea north and north-west 

 of Iceland are on the whole considerably higher than those ob- 

 served during the Ingolf Expedition in the beginning of August 

 1896. 



The distribution of salinity on the sea surface seem to have 

 been subject to similar variations, but the determinations of the 

 salinity are not made with a sufficiently high degree of^accu- 

 racy for previous years to allow of any certain conclusions in 

 this respect. It seems, however, as il the belt with a surface- 

 salinity above 35 °/oo has been widest in July, 1900, when the 

 surface-temperature off the Norwegian coast was relatively low, 

 and narrowest in July, 1897, when the latter was highest. 



The distribution of salinity at the sea-surface between Lo- 

 foten and Jan Mayen seem to have been much the same in Au- 

 gust, 1900, as found by the Norwegian North Atlantic Expedi- 

 tion in July, 1877, only that our salinities seem to have been 

 somewhat lower at the sea-surface just east of Jan Mayen. Our 

 surface-temperatures in this sea were, however, higher than those 

 observed in 1877 ; but the reason may be that we were there 

 a few weeks later in the season. 



In the northern part of the Norwegian Sea, Dr. Hjort found 

 in September, 1900, surface-temperatures and sahnities which 

 were strikingly lower than those found by the North Atlantic 

 Expedition in 1878, and also lower than those found by the 

 Swedish Expeditions in August and September, 1896 (and July 

 1897). 



The surface-salinity of this sea does not, however, seem to 

 have been markedly lower than observed in September 1896.
