The mean tempe- 

 rature of Isachsen's 

 Stats. 17, 18, and 

 19 of July 17th — 

 1 8th, 1 910, was 

 2.50 C 



Owing to the hig- 

 her latitude and the later season, 

 the mean temperature of Arrhe- 



nius' stations should be reduced to about 1.85" C. for com- 

 parison with that of Isachsen's stations. 



The current should accordingly have been 0.65° C. colder 

 in 1896 than in 19 10, but this result will have to be con- 

 sidered as very doubtful. 



The mean temperatures for 100, 200, 300. and 400 

 metres for other stations in this region, are given in the fol- 

 lowing table : ^ 



1 At Isachsen's Stat. 37 and the Belgica Stat. 3 (B 3), the temperature in 400 metres 

 had to be taken from the probable vertical temperature-curves.
