In the introduction to a Treatise entitled “The Uncertainty of the Signs of Death, and the Danger of Precipitate Interments,” published in 1746, the author, Mr. M. Cooper, surgeon, says:--“Though death at some time or other is the necessary and unavoidable portion of human nature, yet it is not always certain that persons taken for dead are really and irretrievably deprived of life, since it is evident from experience that many apparently dead have afterwards proved themselves alive by rising from their shrouds, their coffins, and even from their graves. It is equally certain that some persons, too soon interred after their supposed decease, have in their graves fallen victims to a death which might otherwise have been prevented, but which they then find more cruel than that procured by the rope or the rack.” The author quotes Lancisi, first physician to Pope Clement XI., who, in his Treatise _De subitaneis mortibus_, observes:--“Histories and relations are not the only proofs which convince me that many persons supposed to be dead have shown themselves alive, even when they were ready to be buried, since I am induced to such a belief from what I myself have seen; for I saw a person of distinction, now alive, recover sensation and motion when the priest was performing the funeral service over him in church.” After reporting and describing a large number of cases of premature burial, or of narrow escapes from such terrible occurrences, in which the victims of hasty diagnosis were prepared for burial, or revived during the progress of the burial service, Mr. Cooper continues:--“Now, if a multiplicity of instances evince that many have the good fortune to escape being interred alive, it is justly to be suspected that a far greater number have fallen victims to a fatal confinement in their graves. But because human nature is such a slave to prejudice, and so tied down by the fetters of custom, it is highly difficult, if not absolutely impossible, to put people on their guard against such terrible accidents, or to persuade those vested with authority to take proper measures for preventing them.”
