The results with cadmium are therefore essentially the 

 same as with sodium, aud are perhaps even more convincing 

 from the fact that the red cadmium line is almost ideally 

 simple. Further, the fact that the same results are obtained 

 under such very different conditions (metallic cadmium 

 vapour in a vacuum as against sodic carbonate in a blowpipe 

 flame) would seem to furnish additional evidence against the 

 reversal hypothesis. 



The light from sodium in a vacuum-tube lias a somewhat 

 complicated and variable structure, but in one experiment, 

 the result of which is given in fig. 5, the visibility curve

(envelope) is relatively simple, and the corresponding 

 intensity curves (fig. 6) show results almost identical with
