Mr. 0. J. Lodge. Experiments on 



[June 4> 



42. Summary of Experiments with Tube-condenser No. 1. 

 (" Longer Leads.") 



The readings were not all taken on the same day ; and the length of 

 the equivalent A spark, as read on different days, is recorded at the 

 top of each column. The wave-length is the same in each case, and 

 rough calculation makes it probably about 27 metres when the kick 

 is at a maximum. This may be supposed to be the second harmonic 

 of the vibration period of the long leads.
