When children are dead born, or expire soon after the birth, the same means ought to be used for their recovery, as if they had expired in circumstances similar to those mentioned above. These directions may likewise be extended to adults, attention being always paid to the age and other circumstances. * * * * * The foregoing cases and observations afford sufficient proof of the success which may attend the endeavours of persons totally ignorant of medicine, in assisting those who are suddenly deprived of life by any accident or disease. Many facts of a similar nature might be adduced, were it necessary, but these, it is hoped, will be sufficient to call up the attention of the public, and to excite the humane and benevolent to exert their utmost endeavour for the preservation of their fellow creatures. In short, not only the ordinary signs are very uncertain, but we may say the same of the stiffness of the limbs, which may be convulsive; of the dilation of the pupil of the eye, which may proceed from the same cause; of putrefaction, which may equally attack some parts of a living body, and of several others. Haller, convinced of the uncertainty of all these signs, proposes a new one, which he considers as infallible.--“If the person (says he) be still in life, the mouth will immediately shut of itself, because the contraction of the muscles of the jaw will awaken their irritability.” The jaw however, may be deprived of its irritability though a man may not be dead. Life is preserved a long time in the passage of the intestines. The sign pointed out by Dr. Fothergill appears to deserve more attention.--“If the air blown into the mouth, (says this physician) passes freely through all the alimentary channels, it affords a strong presumption, that the irritability of the internal sphincters is destroyed, and consequently that life is at an end.”--These signs, which deserve to be confirmed by new experiments, are doubtless not known to Undertakers.
