they would one pursue. On the one hand the aérial fil- 
aments being unsuitable for the conveyance of the electric waves, 
these are forced by them out of the normal path, first in one 
direction, then in another; while on the other hand, the finest 
metallic filament furnishes a channel for the electric Ride! so 
favorable that this channel is pursued, although the consequent 
eg ag of the conducting particles be so intense as to make 
y asunder with explosive violence. Even when a bell 
jae has been dissipated by lightning, it has been found to facili- 
tate and determine the path of the discharge.

the peculiarity of the spark is partially the consequence of the 
polarizability of the gaseous atoms through which the eee

ponderable Atoms of the bodies ‘affected, are deranged from 
their natural state of neutralized Polarity.

‘affection of ponderable particles; and that the reason why t 
most intense statical charge does not affect a galvanom aes 
is, that it is only when oppositely excited bodies are neutraliz- 
ed by the interposition of a conductor, as during a discharge, 
that ethereo-ponderable particles are sufficiently polarized to 
enable them to act upon others in their vicinity, so as to pro- 
ce a polar affection the opposite of their own. In this way 
mamic induction is consistently explained, by supposing that
