In my reign, however, tangible and visible proofs established beyond
doubt that every kind of body and substance, whether animate or
inanimate, contains an electricity of its own.
Although all electricities contain air electricity, and are similar in
some other respects, yet each differs from all others by reason of some
properties peculiar to itself, the species being different, though the
genus is the same. As in the case of the blood of animals, which is
called by the common name of blood in spite of material differences,
when the species is different, so we have a generic name for all
electricities, a term signifying "A spark of Heaven power."
Some electricities are diffused and attenuated; some are concentrated;
others are so tenacious of the body to which they belong that they are
all but steadfast. Some are sympathetic; some antipathetic, attracting
or repelling each other; some mingle gently; others, when brought into
contact, cause violent explosions.
