﻿782 Principal Series in the Spectra of the Alkali Metals. 



In the case of Lithium the results are not quite so 



satisfactory. Hicks finds the convergence-frequency to be 



43482-20 + 1-18. Bevan uses 43482-98, but points out that his 



latest measurements indicate a higher convergence-frequency.
