This investigation was made over the period 1899/1900 —1913,1914 
for a combination of five Dutch stations, Flushing, Maestricht, de 
Bilt, Helder and Groningen, for three German stations together, 
Görlitz, Ratibor and Posen and for a combination in the far North- 
West viz. Angmagsalik (Greenland), Akureyri and Stykkisholm 
(Iceland). 
The choice of these combinations has not been an accidental one. 
Precursory calculations demonstrated that the largest posztive cor- 
relation was found in East-Germany, the largest negative in North- 
Ieeland and East-Greenland.

These results partially agree with Meinarpus’s conclusions, where 
he found the greatest correlation to exist, between fluctuations of 
the watertemperature in the Norwegian Sea and those of the air- 
temperature in South-Sweden and the Southern and Western parts 
of the Baltic.
