of ashower of meteors seen by him on the 23d of November. 
Mr. Ewine had also seen the meteors, and Dr. Botton 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 eyvi- 
dences of the phenomenon could be obtained on account of the 
difficulty of excluding the direct visible light of the spark from 
the mauecscent light. }
