drowning, even the most hideous mutilation under a railway train, is as nothing compared with burial alive. Strangely enough this universal horror seems to have produced no desire to guard against burial alive. We all fear it, and yet practically no one takes any trouble to avoid the risk of it happening in his own case, or in that of the rest of mankind. It would be the simplest thing in the world to take away all chance of burying alive; and yet the world remains indifferent, and enjoys its horror undisturbed by the hope of remedy.” The authors’ own reasonings, opinions, and conclusions are here briefly presented; but as the majority of the public are more or less influenced by authority, it has been thought advisable to furnish a series of authenticated facts under the several headings to which they belong, and to cite the judgments of eminent members of the medical profession who have given special attention to the subject. The source of difficulty has been an _embarras de richesse_, or how from a mass of material, the extent of which will be seen by reference to the Bibliography, to select typical cases without needless repetition. The premature burials and narrow escapes from such disasters, which are reported by distinguished physicians and reputable writers, may be numbered literally by hundreds, and for every one reported it is obvious from the nature of the case that many are never heard of. Amongst the names of notable persons who have thought the subject sufficiently practical for their attention may be mentioned those of Empedocles, Plato, Aristotle, Cicero, Pliny, Celsus, Plutarch, and St. Augustine in antiquity; of Fabricius, Lancisi, Winslow, Haller, Buffon, Lavater, Moses Mendelssohn, Hufeland, and Alexander von Humboldt in modern times. The subject has several times engaged the attention of the French Senate and Legislative Chamber, as well as the Legislative Assemblies in the various States of Germany. In 1871, Dr. Alex. Wilder, Prof. of Physiology and Psychological Science, read a paper before the members of both houses of the New York State Legislature at the Capitol, Albany; but we are not aware that the subject has ever been introduced in any of the other State Legislatures, or in the British Parliament, or in any of the Colonial Assemblies. In an editorial note, as far back as November 27, 1858, the _Lancet_, referring to a case of death-trance, remarked that such “examples are sufficiently mysterious in their character to call for a more careful investigation than it has hitherto been possible to accord to them.” The facts disclosed in this treatise, the authors hope, may encourage qualified scientific observers to study the subject of death-trance, which, it must be admitted, has been strangely overlooked in England, though it would not be easy to mention one which more deeply concerns every individual born into the world.
