magnets and either electro-magnets or volta-electric currents, is
strikingly in accordance with and confirmatory of M. Ampère's theory, and
furnishes powerful reasons for believing that the action is the same in
both cases; but, as a distinction in language is still necessary, I propose
to call the agency thus exerted by ordinary magnets, _magneto-electric_ or
_magnelectric_ induction (26).

59. The only difference which powerfully strikes the attention as existing
between volta-electric and magneto-electric induction, is the suddenness of
the former, and the sensible time required by the latter; but even in this
early state of investigation there are circumstances which seem to
indicate, that upon further inquiry this difference will, as a
philosophical distinction, disappear (68).[A]

§ 3. _New Electrical State or Condition of Matter._[A]

[A] This section having been read at the Royal Society and reported
upon, and having also, in consequence of a letter from myself to M.
Hachette, been noticed at the French Institute, I feel bound to let it
stand as part of the paper; but later investigations (intimated 73.
76. 77.) of the laws governing those phenomena, induce me to think
that the latter can be fully explained without admitting the
electro-tonic state. My views on this point will appear in the second
series of these researches.--M.F.
