they lose
their fire; the particles of the other clouds close in receiving
it: in both, they have thereby an opportunity of coalescing into
drops.--The concussion, or jerk given to the air, contributes also to
shake down the water, not only from those two clouds, but from others
near them. Hence the sudden fall of rain immediately after flashes of
lightning.

34. To shew this by an easy experiment: Take two round pieces of
pasteboard two inches diameter; from the centre and circumference of
each of them suspend by fine silk threads eighteen inches long, seven
small balls of wood, or seven peas equal in goodness: so will the
balls appending to each pasteboard, form equal equilateral triangles,
one ball being in the centre, and six at equal distances from that,
and from each other; and thus they represent particles of air.
Dip both sets in water, and some adhering to each ball, they will
represent air loaded. Dexterously electrify one set, and its ball
will repel each other to a greater distance, enlarging the triangles.
Could the water supported by seven balls come into contact, it would
form a drop or drops so heavy as to break the cohesion it had with
the balls, and so fall. Let the two sets then represent two clouds,
the one a sea cloud electrified, the other a land cloud. Bring them
within the sphere of attraction, and they will draw towards each
other, and you will see the separated balls close thus; the first
electrified ball that comes near an unelectrified ball by attraction
joins it, and gives it fire; instantly they separate, and each flies
to another ball of its own party, one to give, the other to receive
fire; and so it proceeds through both sets, but so quick as to be in
a manner instantaneous. In the cohesion they shake off and drop their
water, which represents rain.

35. Thus when sea and land clouds would pass at too great a distance
for the flash, they are attracted towards each other till within that
distance; for the sphere of electrical attraction is far beyond the
distance of flashing.

36. When a great number of clouds from the sea meet a number of
clouds raised from the land, the electrical flashes appear to strike
in different parts; and as the clouds are jostled and mixed by the
winds, or brought near by the electrical attraction, they continue
to give and receive flash after flash, till the electrical fire is
equally diffused.

37. When the gun-barrel, (in electrical experiments) has but little
electrical fire in it, you must approach it very
