In fig-ure 60 one may see that the curves for the temperature varia- 

 tions both for the whole Atlantic Ocean and for the middle part 

 of it have great similarity to the curves of variation of air tempera- 

 ture in the tropics and in the south temperate zone, also for the 

 whole earth and in part a similarity to those of North America.

Figure 6o. Curves for the yearly anomalies of air temperature according 

 to Mielke in North America, the Tropics, Southern Temperate Zone, the 

 whole earth (I to IV), the surface temperature in the Danish field 20° to 

 29° west longitude, and in the two Danish fields 20° to 29° west longitude 

 and 30° and 39° west longitude (VI, a for the calendar year, b for September 

 to August), in the equatorial field of the Central Bureau (IXb), and at Liepe's 

 station VIII (IXa). The temperature anomalies of the surface along the 

 route Channel New York in February (VII), and February-April (VIII). 



This similarity to the yearly variations of air temperature holds 

 for the surface temperature, both for the whole year, as shown in 

 curves V, VI, and IX, and for February, shown in curve VII, and 

 also for February to April, curve VIII. 



Figure 6i shows great similarity between the curves for the varia- 

 tion in the surface temperature in the eastern part of the Atlantic
