Abstract
PROF. COLWELL and Mr. Friend1 state that from results of experiments conducted by them they have been led to believe that, besides the usual E and F regions of the ionosphere, there is a third region—the D region—at a height of 5–55 km. They further say: ” Such a layer has been postulated before as an absorption layer in the ozone region, but its reflecting powers have not been emphasised”.
