Abstract
FABRY and Buisson1 have shown that the short wave-length limit of the spectrum of the sun near 2900 A. is due to the absorption by ozone in the atmosphere of the earth. This absorption of the ultra-violet Hartley band of ozone begins at the wave-length 3100 A. and reaches a maximum at 2540 A. (Läuchli2). It is important to notice that the absorption falls rapidly on the short wave-length side of the band. Edgar Meyer3 first pointed out that this property of ozone gives an opportunity of observing sunlight in the region of 2100 A. Several investigators searched for this short wave-length radiation, but without any success4. The reason for this is mainly given by the fact that below 2600 A., the atmospheric oxygen is strongly absorbing over long distances5, so that it is necessary to use extremely sensitive ap paratus to detect any radiation of this wave-length.
