Dr. Hare on the Theories of Electrical Phenomena. 231 
Wire of great length, to be made the medium of discharge to a 
yden jar; agreeably to the hypothesis of one fluid, the electri- 
cal filament must be attracted at one end of the wire, and pro- 
pelled at the other, as soon as its terminations are brought into 
de communication with the coatings of the jar. Yet the influ- 
ence of the oppositely charged surfaces of the jar, cannot be con- 
ceived to extend to those portions of the electricity which are re- 
, Mote from the points of contact, until they be reached by a suc- 
Cession of vibrations. Hence it is inconceivable, that every par- 
ticle in the filament of electric matter can be made at the same 
time to move, so as to constitute a current having the necessary 
Velocity and volume to transfer, instantaneously, the electricity 
requisite to constitute a charge. Even the transmission of the 
impulses, in such an infinitesimal of time, seems to be incon- 
ceivable, . 
_ 5. In reply to these objections, it has been urged by the Frank- 
linians, that ‘a conductor being replete with electricity, as soon as 
this fluid should be moved at one end, it ought to move at the 
other. ‘This might be true of a fiuid if incompressible, but could 
hot hold good were it elastic. A bell wire moves at both ends 
when pulled only at one; but this would not ensue were a cord 
of gum elastic substituted for the wire.
