I answer, and proudly maintain, ""That this increase of weight comes from the air, thickened and made heavy, and in some measure rendered adhesive in the vessel by the violent and long—continued heat of the furnace—which air mixes with the calx , and attaches itself to its smallest particles—no otherwise than as water, when sand is thrown into it, makes it heavier by moistening it, and adhering to its smallest grains.

Plants too ought to become heavy by death, the celestial heat being expelled: but the contrary is evident to all. As to the increased weight of animals by death, the true cause, far remote from that which increases the weight of lead when calcined, is this: in the living animal its natural heat subtilizes, dilates, and augments the dimensions of the humours, the flesh, and every thing in it capable of dilatation—but losing this heat by death, the whole on this becoming cold, contracts and diminishes, whence the increase of weight, as I have often said already. What is there like this in lead?

With regard to the celestial heat making bodies light, Scaliger very properly objects that the heavens, which abound in this heat, as being the source of it, must be light and consequently univocal with the other bodies, which is absurd.

Now casting a look on all that moves, I see nothing that ascends by its own proper motion. Water, indeed, rises in a glass, if we throw earth into it; but all will allow, that it is not from any levity that is in the water, but rather, that the earth, by falling to the bottom, makes the water ascend. Now, if water does not acknowledge levity as the cause of this motion upwards, why should air confess it, which ascends in like manner when pressed on by water? Why fire, which does the same? It will be said, I doubt not, that if the upward motion of the elements be not natural to them, it must be violent; whence this absurdity follows, that each obtains its place in the universe by force. To this I answer, that the elements not having the cause of these motions in themselves, they may, so far, be called violent; but that this violence is gentle, and nowise ruinous.
