of a shower of meteors seen by him on the 23d of November. 

 Mk. Ewing had also seen the meteors, and Dr. Bolton had heard 

 of them. 



Addendum to the Abstract of Dr. Pupin's Paper "On 

 the Bearing of Electrical Discharges on Solar 



Physics." 



Among the lines of laboratory research one was especially 

 recommended and that was the investigation of the fluorescence 

 of perfect gases under the influence of the light of powerful 

 electrical discharges. Dr. Pupin stated that he believed that 

 these gases are rendered fluorescent by the action of the light 

 of very powerful oscillatory jar discharges. [In one of his 

 experiments, which he showed to Professors Rees and Van Am- 

 ringe, of Columbia College, ten days before the reading of the 

 paper, he thinks that he succeeded in rendering hydrogen fluor- 

 escent (with a faint bluish color) by the action of the light of 

 exceedingly powerful jar discharges ; but no conclusive evi- 

 dences of the phenomenon could be obtained on account of the 

 difficulty of excluding the direct visible light of the sj)ark from 

 the fluorescent light.]
