The uterine souffle affords us little aid in the diagnosis of the child's death: it is frequently very distinct when the child is evidently alive; and where it has been heard previous to its death, it will continue for some hours afterwards, although with diminished strength and over a smaller space. During labour there are a variety of symptoms, by the aid of which we can pronounce, with a very tolerable degree of certainty, whether the child is alive or not; if alive, the foetal heart can invariably be detected; and, for the reasons above stated, will be heard more distinctly than in the earlier months of pregnancy. If, from the violence or duration of the labour, or any other cause, the child is becoming exhausted, the pulsations become weaker and slower until they stop; so that by the aid of auscultation we possess distinct evidence of the child's life being endangered, and of its complete extinction. If the _head_ presents during labour, a firm elastic swelling (caput succedaneum) will rise on that portion of it which first enters the vagina: this is produced by the circulation in the presenting part of the scalp being obstructed by the pressure which the os uteri and vagina exert upon it, an effect which can only be produced upon the head of a living child: where, on the other hand, the child is dead, the scalp will be felt to be soft, flabby, and without swelling. This may be looked upon as a very certain proof of the child's death in primiparæ, where the head is advancing slowly, and where it is tightly encircled by the distended vagina. But in multiparæ, where the soft passages have been dilated by repeated labours, the pressure upon the head is so slight, and its passage through them so rapid, that little or no swelling is produced: even in these cases the finger of the accoucheur will easily distinguish the head of a dead child by the loose yielding flabby feel of its integuments; the cranial bones are more moveable, and overlap each other at the sutures more than usual; their edges feel sharp, as if no longer covered by the scalp; and frequently communicate a grating sensation when they rub against each other. The great fontanelle is flaccid and loose; the bones, which form it, appear falling together, from a want of sufficient contents to keep them asunder, a circumstance which probably arises from the circulation in the brain having ceased; and in those cases where the child has already been dead some time, a crackling or crepitous sensation is communicated to the finger from emphysema, the result of decomposition.
