CLIMATOLOGICAL AVERAGES VON BEZOLD 429 



or <p = 38° 1 8', and in the southern hemisphere at sin cp = 0.57 

 or <p = 35 00' — so that here also within a zone that covers 0.6 of 

 the whole surface of the earth there prevail temperatures that lie 

 above the average, whereas outside of this zone or over the polar 

 segments, thaf both together cover 0.4 of the total surface, the 

 temperatures are below the general average. 



These statements may suffice to give an idea of the great advan- 

 tages offered by the method of presentation here employed. 



The important conclusions that we can draw on this basis with 

 reference to the thermal economy at the earth's surface and in 

 the atmosphere will be reserved for a future memoir.
