Again, I imagine that in many persons death is caused by the coagulation of the blood, which freezes and hardens in their veins, as it happens with those who have eaten hemlock, or who have been bitten by certain serpents; but there are others whose death is caused by too great an ebullition of blood, as in painful maladies, and in certain poisons, and even, they say, in certain kinds of plague, and when people die a violent death, or have been drowned.
The first mentioned cannot return to life without an evident miracle; for that purpose the fluidity of the blood must be re-established, and the peristaltic motion must be restored to the heart. But in the second kind of death, people can sometimes be restored without a miracle, by taking away the obstacle which retards or suspends the palpitation of the heart, as we see in time-pieces, the action of which is restored by taking away anything foreign to the mechanism, as a hair, a bit of thread, an atom, some almost imperceptible body which stops them.

CHAPTER LI.
APPLICATION OF THE PRECEDING INSTANCES TO VAMPIRES.
Supposing these facts, which I believe to be incontestably true, may we not imagine that the vampires of Hungary, Silesia, and Moldavia, are some of those men who have died of maladies which heat the blood, and who have retained some remains of life in their graves, much like those animals which we have mentioned, and those birds which plunge themselves during the winter in the lakes and marshes of Poland, and in the northern countries? They are without respiration or motion, but still not destitute of vitality. They resume their motion and activity when, on the return of spring, the sun warms the waters, or when they are brought near a moderate fire, or laid in a room of temperate heat; then they are seen to revive, and perform their ordinary functions, which had been suspended by the cold.
