And so in other cases, especially of sudden maternal death, it is of importance to ascertain as nearly as possible the period at which death of the fœtus took place. If the two were coincident, the deduction might be other than if the latter were proved to have preceded the former by several days. The differences observed between putrefaction and decomposition in utero and in the open air must not be lost sight of. In the one case, according to Orfila, Devergie and Martin, Moreau, P. Dubois, Danyau, Cazeaux, Tardieu, and my own experience, a uniform and characteristic reddish-brown hue obtains in proportion to the time of retention after death, varied perhaps by the action of the amniotic fluid;[128] the fœtus wrinkles, dries, and becomes mummified, unless in earliest pregnancy, when it generally resolves itself into a gelatinous mass.

If the cervix, the portion of the uterus most frequently wounded, is found punctured or lacerated, while the ovum is still retained, there is reason for suspicion; if the membranes are torn and extensively detached, while the cervix is but little dilated, such is increased; and it is made almost a certainty, if with the latter condition, nothing remain of the ovum in the uterine cavity but lacerated fragments. Here the abortion would probably not merely have been intentionally induced, but by the direct introduction and agency of instruments.

Wounds of the fœtus are much rarer than those of the mother, and are usually simple pricks of the skin marked by blackish coagula or extravasations; which, if upon the skull and unless care be used, are liable to be simulated by clots casually adhering to the hair or scalp. If the wound be deeper, its course may be traced by dissection. Its situation varies; Devergie thinking it always on the back and buttocks, while Tardieu, with some warmth, would restrict its location to the top of the cranium. This difference is easily explained by variations in the time of pregnancy, and in consequence partly, as may also depend on its life or death, in the presentation of the child. The rarity of their occurrence, though denied by Taylor[129] and other medical jurists, might, however, be expected, and is readily accounted for; the instruments used by ignorant persons seldom entering the os, however severely wounding the cervix, and where they do enter, usually only piercing the membranes; against which, except toward the end of pregnancy, in a deficiency of liquor amnii, or in labor, the fœtus can hardly be said to forcibly press.

4. The Identity of the Party Accused.

Most of the points here involved having already been incidentally considered, we will not repeat them. The circumstances and history of the case, the relative correspondence of different testimony, the allegations of the accused, will all bear directly upon the question at issue.

In trials for abortion, of all others, the medical witness and the advocate should bear in mind their liability to error; the juror and the judge the fact that innocent persons are at times wrongly accused, often by the true criminals themselves.

In defence, it must either be pleaded that the alleged abortion did not occur, that it was accidental or natural, that it was necessitated, or that it was induced by another than the individual charged.

The first of these pleas is seldom offered except in the earliest months of pregnancy, and would be invalid if an attempt at the abortion could be proved. In default of this, however, where the ovum has been lost, or has passed unnoticed, the fact that the sanguineous effusion was hemorrhagic and attended with clots, would, in the absence of any uterine disease sufficient to account for this, be so far presumptive evidence; to be corroborated or not by the history of the case. Moles and hydatids are now generally allowed to be mere transformations of the product of conception; their premature discharge, therefore, equally an abortion.

In answer to the second plea, the importance of several points must be borne in mind. It has been well put by Tardieu that it is wrong to commence, as advised by most authorities on the subject, by enumerating all the natural and accidental causes liable to have produced the abortion. On the contrary, the signs and proofs of criminal violence should first be sought, and these compared with the allegations of witnesses and the possibility of a natural or accidental origin. The traces of falls, contusions, and wounds must be found, not believed on mere allegation; coincidences must be guarded against, equally with untruth.
