To those who, like physicians, students and nurses, are almost constantly thrown into direct contact with every form of epidemic, contagious and infectious diseases, the dangers arising therefrom are considerable. But undertakers are exposed to a still greater risk, namely: that of handling the remains of those who have died from the effects of those same diseases. Not only do they have to guard against the infectious character of the contagion, but they have also to protect themselves against the malignant effluvia which emanates from the victims of the contagion after disintegration of the body has taken place, the nauseous and sickening gases which are generated by decay, and the deadly virus which may be innoculated into the system, either through some puncture or abrasion of the skin; the virulent effects of the poison may be carried carelessly to the mouth, the nose or the eyes by a thoughtless action. Too much care cannot be exercised by undertakers in handling a corpse, especially if the subject is known to be afflicted with some infectious or malignant complaint. Still, the precautions generally in use among undertakers, and the different preparations that are commonly recommended as preventives, are useless in most cases, as there are conditions of the system which will increase the danger, and in some instances leave it open to the insidious attacks of disease and contagion. Too much importance has been attached, so far, by undertakers, to the artificial means devised by some, under the names of preservatives, antidotes, etc., etc. The reliance placed on them, in a great many cases, has proved futile, and although some possess real and undisputed merit, they proved ineffectual when the system has been influenced by the following CONDITIONS OF THE SYSTEM, which will increase the danger of contagion: _Fear._—Almost in every case, if a person is brought in sudden contact with the remains of one who has died of either cholera, small pox, yellow fever, or any of those terrible epidemic and contagious diseases which will in a few weeks decimate a populous city, the feeling will be one of repulsive horror; in some this feeling will amount to absolute fear, which will show itself in the dilated pupil, the bleached countenance, and the momentous forebodings which assail the mind and predispose the system to the attacks of the disease. In this case, the mind influences the body to such an extent that the disease has already fastened itself upon the system, before the first symptoms are felt. Another and potent cause of danger is that which proceeds from a debilitated condition of the system, the causes of which are numerous: over-exertion of either the body or the mind; labor carried on incessantly without due regard to relaxation; imperfect nutrition, or long fast, are all causes which will tend to render the system more vulnerable to the aggressions of sickness.
