✦ Synopsis

oration with the Bartol Research Foundation, W. F. G. Swann has given a discussion of the foregoing matter, particularly in its relation to variation of spectral distribution curve with altitude. At high altitudes the spectral distribution curve is narrow. At low altitudes it is broad, with the maximum at a larger value of the momentum.

Calculations resulting from the considerations cited have been made on the basis of existing data for the spectral distribution curve at two altitudes, 6.7 km and sea level. They serve to exhibit the fact that a dip in the absorption curve is to be expected and that it is very much more rapid at high altitudes than at sea level.
