_my hypothesis_, since I find Stuart
had the same thought, though somewhat obscurely expressed, where he says
"he imagines this phenomenon may be solved by suction (improperly so
called) or rather pulsion, as in the application of a cupping-glass to
the flesh, the air being first voided by the kindled flax."

In my paper, I supposed a whirlwind and a spout to be the same thing,
and to proceed from the same cause; the only difference between them
being that the one passes over the land, the other over water. I find
also in the _Transactions_, that M. de la Pryme was of the same opinion;
for he there describes two spouts, as he calls them, which were seen at
different times, at Hatfield, in Yorkshire, whose appearances in the air
were the same with those of the spouts at sea, and effects the same with
those of real whirlwinds.

Whirlwinds have generally a progressive as well as a circular motion; so
had what is called the spout at Topsham, as described in the
Philosophical Transactions, which also appears, by its effects
described, to have been a real whirlwind. Water-spouts have, also, a
progressive motion; this is sometimes greater and sometimes less; in
some violent, in others barely perceivable. The whirlwind at Warrington
continued long in Acrement Close.

Whirlwinds generally arise after calms and great heats: the same is
observed of water-spouts, which are, therefore, most frequent in the
warm latitudes. The spout that happened in cold weather, in the Downs,
described by Mr. Gordon in the _Transactions_, was, for that reason,
thought extraordinary; but he remarks withal, that the weather, though
cold when the spout appeared, was soon after much colder: as we find it
commonly less warm after a whirlwind.

You agree that the wind blows every way towards a whirlwind from a large
space round. An intelligent whaleman of Nantucket informed me that three
of their vessels, which were out in search of whales, happening to be
becalmed, lay in sight of each other, at about a league distance, if I
remember right, nearly forming a triangle: after some time, a
water-spout appeared near the middle of the triangle, when a brisk
breeze of wind sprung up, and every vessel made sail; and then it
appeared to them all, by the setting of the sails and the course each
vessel stood, that the spout was to the leeward of every one of them;
and they all declared it to have been so when they happened afterward in
company, and came to confer about it. So that in this particular,
likewise, whirlwinds and water-spouts agree.
