Its _rising again_ shows that the prime conductor lost little or
none of its electric charge, as it had done through the point: the
_falling_ of the ball while the large body was under the conductor
therefore shows, that a quantity of its atmosphere was drawn from the
end where the electrometer is placed to the part immediately over the
large body, and there accumulated _ready_ to strike into it with its
whole undiminished force, as soon as within the striking distance;
and, were the prime conductor moveable like a _cloud_, it would
approach the body by attraction till within that distance. The swift
motion of clouds, as driven by the winds, probably prevents this
happening so often as otherwise it might do: for, though parts of
the cloud may stoop towards a building as they pass, in consequence
of such attraction, yet they are carried forward beyond the striking
distance before they could by their descending come within it.
