acciiniulation, nor to any deficiency either of one or ot two 

 fluids, but to the opposite polarities induced in imponderable 

 aethereal matter existing throughout space however otherwise 

 void, and Hkewise condensed more or less within ponderable 

 bodies, so as to enter into combination with their particles, 

 forming atoms which may be designated as aethereo-ponde- 

 rable. 



Frictional charges of electricity seek the surfaces of bodies 

 to which they may be imparted, without sensibly affecting the 

 aethereo-ponderable matter of which they consist. 



When surfaces thus oppositely charged, or, in other words, 

 having about them oppositely polarized fethereal atmospheres, 

 are made to communicate, no current takes place, nor any 

 transfer of the polarized matter : yet any conductor touching 

 both atmospheres, furnishes a channel through which the op- 

 posite polarities are reciprocally neutralized by being commu- 

 nicated wave-like to an intermediate point. 



Galvano-electric discharges are likewise effected by waves 

 of opposite polarization, without any flow of matter meriting 

 to be called a current. 



But such waves are not propagated superficially through 

 the purely aethereal medium ; they occur in masses formed 

 both of the aethereal and ponderable matter. If the generation 

 of frictional electricity, sufficient to influence the gold leaf 

 electrometer, indicate that there are some purely aethereal 

 waves caused by the galvano-electric reaction, such waves 

 arise from the inductive influence of those created in the 

 aethereo-ponderable matter. 



When the intensity of a frictional discharge is increased 

 beyond a certain point, the wire remaining the same, its powers 

 become enfeebled or destroyed by ignition, and ultimately 

 deflagration : if the diameter of the wire be increased, the sur- 

 face, proportionally augmented, enables more of the aethereal 

 waves to pass superficially, producing proportionally less 

 aethereo-ponderable undulation. 



Magnetism, when stationary, as in magnetic needles and 

 other permanent magnets, appears to be owing to an enduring 

 polarization of the aethereo-ponderable atoms, like that transi- 

 ently produced by a galvanic discharge. (Note page 461 and 

 paragraph 68.) 



The magnetism transiently exhibited by a galvanized wire 

 is due to oppositely polarizing impulses, severally proceeding 

 wave- like to an intermediate part of the circuit where reci- 

 procal neutralization ensues. 



When magnetism is produced by a frictional discharge 

 operating upon a conducting wire, it must be deemed a secon-
