OF ARTS AND SCIENCES. 407 



As exhibiting the electrostatic activity of the rapidly alternating 

 electrostatic field around the apparatus, a long Geissler tube without 

 metallic terminals was used, and brilliantly illuminated even at dis- 

 tances several feet away from the outside of the vat containing the 

 induction apparatus. The tube, however, failed to light in one posi- 

 tion ; that is, in the centre plane dividing the apparatus into halves, 

 which during action are electrified respectively positively and nega- 

 tively at each alternation (Figure 10). 



At the close of the experiments a vote of thanks was 

 extended to the speaker. 



S. H. Sc udder exhibited a medal struck to celebrate the one
