Abstract
IN preceding communications (NATURE, NOV. 2, 1929, and Comptes rendus, Jan. 1930) we have given a brief account of the extension of the extreme ultraviolet down to 100 resp. 88 A. in the spectrum of doubly ionised beryllium (Be III). Using a vacuum-spark with a considerably increased capacity and ionisation power, it has now been possible to record the strongest radiations in the hydrogen-like spectra of completely ionised lithium (Li III) and beryllium (Be IV), thus extending optical spectra to 76 A.
