of Petersen's middle stations III to VIII (between 22° and 47° 

 west longitude; see also fig. i, stations 3 to 8) and in Liepe's three 

 most southerly stations (pi. 15, stations VI, VII, VIII) which cor- 

 respond best with the relations of the middle part of the Atlantic 

 Ocean. These curves we have continued on by means of the curves 

 lb and lib for the most western Danish fields 30° to 39° west longi- 

 tude, and the Dutch field 5° to 14° north latitude, 25° to 34° west

 relative sun spot numbers according to Wolfer. Scale on the left. P-C:

longitude. Curve Ilia for Liepe's station 8 near the equator we have 

 continued on by means of curve Illb for the equatorial field of the 

 Atlantic, whose temperature was furnished us by the Central Bureau. 

 These temperature curves for Petersen's and Liepe's stations and 

 the three other fields show an unmistakable similarity to the tempera- 

 ture curves for the air in the tropics and in the other great regions 

 which are mentioned above. Curve VIII for the surface tempera- 

 ture in the Indian Ocean shows also great similarity to the other 

 curves.
