Since now, on the basis of a definite value of the solar constant, 

 one can at least approximately compute all the quantities relating 

 to insolation, when we know the location of the neutral lines, and 

 since also the approximate determination of the intensities J n and 

 / of the two branches of the schematic flow of heat is not a matter 

 of insuperable difficulty, therefore there is also a possibility of find- 

 ing the quantity of heat radiated outward in the two radiation 

 zones, including that reflected outward from the highest regions of 

 the atmosphere. 



These formulae teach us that we may hope for information as to 

 the interchange of heat in the highest inaccessible regions of the 

 atmosphere as soon as we are successful in determining with suf- 

 ficient accuracy the solar constant and also the intensity of the flow 

 of heat through the two neutral sections. 



Even this latter problem seems not insoluble, at least within cer- 

 tain limits, since in this flow the lower accessible strata principally 

 comes into consideration.
