• The characteristic ultraviolet absorption spectra of glasses with simple compositions were measured to 180 m$\mu$ with a small quartz spectrograph. The following results were obtained: \includegraphics{dummy.eps} To investigate, particularly, the mechanism of the absorption maximum at 237 m$\mu$ of the Pb glass, spectra of acetate- and of plumbite-solution were measured. And, from the evidence that the spectrum of mixed solution of sodium- and lead-acetate coincides with that of the Pb glass, it may be interpreted that the appearance of the absorption maximum of the Pb glass is due to lead ions bonded weakly unsaturated oxygens in the network of SiO4. The variation of luminescence efficiency of them with wave-length of exciting radiations was also measured within the range between $200{\sim}300$ m$\mu$, and it was found that the luminescence maximum appeared near the correspond ing wave-length to the absorption maximum.
