By progressive polarization in a wire, may not stationary polar 
ization, or magnetism be created; and reciprocally by pane 3 
polity may not progressive polarization be excited? am 
. Might not the difficulty, above suggested, of the incompetency. 4 
of any imaginable polarization to produce all the varieties of elec- 
trical excitement which facts require for explanation, be oh 
mounted by supposing intensity to result from an acenmulation  - 
_.. Of free electric polarized particles, and quantity from a still greater 
~ accumulation of such particles, polarized in a latent state or in . 
-ehemical combination ? 
_._. There are it would seem many indications in favor of the idea 
a that electric excitement may be due to a forced polarity, but in 
endeavoring to define the state thus designated, or to explain by 
_ means of it the diversities of electrical charges, currents and ef- 
' fects, I have always felt the incompetency of any hypothesis 
‘which I could imagine. How are we to explain the insensibility 
of a gold leaf electroscope, to a galvanized wire, or the indiffer- 
ence of a magnetic needle to the most intensely electrified sur- 
faces? 
| Possibly the Franklinian hypothesis may be combined with that 
above suggested, so that an electrical current may be constituted 
of an imponderable fluid in a state of polarization, the two elec- 
tricities being the consequence of the position of the poles, or 
_their presentation. Positive electricity may be the result of an 
| accumulation of electric particles, presenting poles of one kind ; 
| negative, from a like accumulation of the same matter with a 
presentation of the opposite poles, inducing of course an oppo- 
| site polarity. 'The condensation of the electric matter, within 
bs ponderable matter, may vary in obedience to a property analogous 
E to that which determines the capacity for heat, and the differ- 
ent influence of dialectrics upon the process of electrical induc- 
tion may arise from this source of variation. 
| With the highest esteem, I am sore truly, 
Rosert Hare.
