Abstract
IN the note above by G. K. Das and one of us (B.D.), it has been pointed out that the transition potential as defined therein with positive rays of hydrogen for the Hα line should be about 7,000 volts. We have carried out a systematic investigation with this line, the current being kept constant at all potentials with times of exposure varied within wide limits. The results are shown in Fig. 1.
