✦ Synopsis

of ultraviolet solar radiation with elevation, it is deduced that the apparatus passed through 65 to 70 per cent. of the ozone, and other ultraviolet-absorbing constituents, if any, in the upper atmosphere, most of which are localized in a layer extending from 15 to 27 km., with a wide maximum of concentration at a height of about 24 to 25 km., above the earth's surface. At the highest elevation attained by the instruments, the intensity of the ultraviolet solar radiation of wavelengths shorter than 3132A was IO to 12 times that observed at sea level.
