the most important witness--the dead body itself--unheard, and the inquest so far valueless.” Which may mean that, without the risk of an autopsy, it is impossible in such cases to determine whether they are beyond resuscitation or not, unless putrefaction settles the question. Unfortunately there is nothing in the external appearance of those cases of so-called sudden death in which the vital machinery may be totally wrecked, to distinguish them from those of apparent death, in which all the organism is in a state of perfect integrity, and in which resuscitation is possible, provided the vital principle has not entirely left the body. Consequently, the only safe rule to observe in all cases in which death has not followed poisoning, or injuries which kill outright, or some known disease of sufficient duration and severity to bring on dissolution, is to wait for unmistakable evidences of decomposition before autopsy, embalming, cremation, or burial is allowed. In former times precipitate interments of persons who died suddenly were specially guarded against. Nothing is more common, on opening a newspaper, than to see one or more announcements of sudden death. These occurrences are so frequent that the great London dailies, except when an inquest is held, or when the deceased is a person of note, omit to record them. The narratives are much alike: the person, described to be in his usual health, is seized with faintness in the midst of his daily-avocation, and he falls down apparently dead; or he retires for the night, and is found dead in his bed. In many instances _post-mortems_ are made, and an inquest held; but in other cases the opinion of the attendant doctor, that the death is due to heart-disease, syncope, asphyxia, coma, apoplexy, or “natural causes,” is deemed sufficient. The friends who are called in to look at the body will remark, “how natural and how life-like,” “how flexible the limbs,” “how placid the face;” and, without the faintest attempt at resuscitation, arrangements are made for an early burial. [DR. WILDER ON SUDDEN DEATH.] Dr. Alexander Wilder, Professor of Physiology and Psychology, in a letter to the author, says:--“There are a variety of causes for sudden death. The use of tobacco is one. Another is overtaxed nervous system. Men of business keep on the strain till they drop from sheer exhaustion. At the base of the brain is a little nerve-ganglion, the medulla oblongata, which, once impaired, sends death everywhere. Overtaxing the strength by study and mental stress will do this. The solar ganglion below the diaphragm is the real vital focus of the body. It is first to begin, last to die. A blow on it often kills. An emotion will paralyse it. Even undue excess at a meal, or the use of overmuch alcohol, may produce the effect.
