about 3.32 ^ C. at Stat. 56 isee the curve Fig. i6i and probably about 1,98'* C. 

 at Stat. 17 (see the curxe Fig. 18). giving a dift'erence of 1.34" C. The dist- 

 ance between the stations was about 335 miles, which gives a decrease 

 of temperature of 0.04 "C. for every 10 miles. The observations at Stat. 

 56 were, however, taken 32 days later than those at Stat. 17. and. if 

 Helland-Hansen and I are right 1912, p. 25]. the mean temperature of the 

 strata bet^^een 50 and 450 metres at Stat. 56 has therefore to be reduced 

 by about 0.30 ^ C. to be comparable with the corresponding temperature at 

 Stat. 1 7. We then find that the decrease in the temperature of the current 

 is 0.034" C. in 10 miles. Helland-Hansen and I have found before [1912, 

 p. 26) that the mean temperature of the Spitsbergen Atlantic Current, be- 

 tween 50 and 450 metres, is on the average lowered about 0.038 ^ C. for 

 every 10 miles the water travels northward, which is a fair agreement.
