The mean temperature of Isachsen's Stats. lo, ii and 12, of June 

 27th — 28th, 1910, is 3.09" C. Owing to the earlier season, this should 

 be raised to 3.42 ° C. in order to be comparable with that of Hamberg's 

 station. 



The current should accordingly^ have been about 0.17° C. warmer in 

 1910 than in 1898. 



The mean temperature of Stat, i (Fig. 21, G i) of the De Geer Expe- 

 dition, on September 2nd, 1908, was 344" C. (see the following Table). 



The mean temperature of Isachsen's Stat. 29, of September 6th, 1910, 

 was 3.31° C. That of his Stats. 28 and 29 of July 22nd, 1910, was 

 2.81° C. Owing to the earlier season, this should be raised to 3.26^ C. 

 in order to be comparable with the former. 



Owing to the more southerly position the mean temperature of G 1 

 should be raised to 3.54 ° C. 



In this region the Current should accordingh- have been about 0.25^ C. 

 warmer in 1908 than in 1910. 



The mean temperature of Mohn's Stats. 353, 354, and 355 was 0.93° C, 

 while that of Isachsen's Stats. 26, 27, 28, and 29 was 2.63° C. Owing to 

 the difference in latitude and in season, the latter value should be cor- 

 rected to 2.78° C. 



According to these values, the current should have been 1.85° C. 

 colder in 1878 than in 1910. 



Owing to the more northerly position, the mean temperature (2.24 ^ C.) 

 of Hamberg's Stat. L, of July 25th, 1898, should be corrected to 2.30" C. 

 in order to be comparable with the mean temperature 2.81 '^ C. of Stats. 

 28 and 29 of July 22nd, 1910. 



The current should accordingly have been 0.51 ^ C. colder in 1898 

 than in 1910. 



Arrhenius' Stations 3—6 of August 21st, 1896, (Fig. 21, A 3— A 6), 

 are north of Isachsen's Section VI. Unfortunately, however, the deep-sea
