The measurements recorded show distinctly the range of the 

 temperature in April and August, 1904. By taking successively the 

 stations 11 (April 23rd), 13 (April 23rd), 14 (April 23rd) and 15 

 (April 24th) it is distinctly seen how the temperature of the surface- 

 water of the ocean along the north coast of Iceland decreases from 

 west to east, as shown by the following figures: — 



St. 11 



2.40° 



St. 13 

 2.34° 



St. 14 

 1.50° 



St. 15 

 0.63° 



A similar decrease of warmth from west to east, but in a far 

 lesser degree, appears to occur in the month of August. 



Station 106 (Aug. 23rd) shows a much lower temperature than
