about 3.32 C. at Stat. 56 (see the curve Fig. 16) and probably about 1.98 C. 

 at Stat. 17 (see the curve Fig. 18), giving a difference of 1.34 C. The dist- 

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

 of temperature of o.o4C. 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 between 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. 17. We then find that the decrease in the temperature of the current 

 is 0.034 C. m I0 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 o.o38C. for 

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



Our Stat. 19 (80 18' N., io45 / E., depth 623 metres) and Stat. 20 

 .(80 21' N., nio / E., depth 587 metres), and also Stats. 43 and 41, were
