[KING] ABSORPTION OF LIGHT IN GASEOUS MEDIA 139 
By making a comparison of the variations of intensity of radiation of 
different wave-lengths over the solar dise with the results of observa- 
tion it will be possible to determine from the observed intensity-curve 
outside the earth’s atmosphere the intensity-curve at the radiating 
layer of the sun. This corrected curve may then be compared with 
Planck’s formula and a closer approximation fnade to the temperature 
of the sun than the values now given. This investigation the writer 
hopes to be able to deal with in a future communication.
