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 St. 13 St. 14 St. 15
2.40° 2.34° 1.50° 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
