Further, the fact that the same results are obtainedunder such very different conditions (metallic cadmiumvapour in a vacuum as against sodic carbonate in a blowpipeflame) would seem to furnish additional evidence against thereversal hypothesis. The light from sodium in a vacuum-tube lias a somewhatcomplicated and variable structure, but in one experiment,the result of which is given in fig. 5, the visibility curve Fig. 5.
