the same stuff. Thus, also, a damp moist air shall make a
man more sensible of cold, or chill him more, than a dry air that is
colder, because a moist air is fitter to receive and conduct away
the heat of his body. This fluid, entering bodies in great quantity,
first expands them, by separating their parts a little, afterwards,
by farther separating their parts, it renders solids fluid, and at
length dissipates their parts in air. Take this fluid from melted
lead, or from water, the parts cohere again, the first grows solid,
the latter becomes ice: and this is sooner done by the means of good
conductors.

[Illustration: (of wooden former for molten lead)]

Thus, if you take, as I have done, a square bar of lead, four inches
long, and one inch thick, together with three pieces of wood planed
to the same dimensions, and lay them, as in the margin, on a smooth
board, fixt so as not to be easily separated or moved, and pour
into the cavity they form, as much melted lead as will fill it,
you will see the melted lead chill, and become firm, on the side
next the leaden bar, some time before it chills on the other three
sides in contact with the wooden bars, though before the lead was
poured in, they might all be supposed to have the same degree of
heat or coldness, as they had been exposed in the same room to the
same air. You will likewise observe, that the leaden bar, as it has
cooled the melted lead more than the wooden bars have done, so it is
itself more heated by the melted lead. There is a certain quantity
of this fluid called fire, in every living human body, which fluid,
being in due proportion, keeps the parts of the flesh and blood at
such a just distance from each other, as that the flesh and nerves
are supple, and the blood fit for circulation. If part of this due
proportion of fire be conducted away, by means of a contact with
other bodies, as air, water, or metals, the parts of our skin and
flesh that come into such contact first draw more near together
than is agreeable, and give that sensation which we call cold; and
if too much be conveyed away, the body stiffens, the blood ceases
to flow, and death ensues. On the other hand, if too much of this
fluid be communicated to the flesh, the parts are separated too far,
and pain ensues, as when they are separated by a

Its inconveniencies are, that people have not even so much sight or use of the fire as in the Holland stoves, and are, moreover, obliged to breathe the same unchanged air continually, mixed with the breath and perspiration from one another's bodies, which is very disagreeable to those.

At the same time the air, warmed under the bottom plate, and in the air-box, rises and comes out of the holes in the side-plates, very swiftly, if the door of the room be shut, and joins its current with the stream before-mentioned, rising from the side, back, and top plates.
