 premature ejection of the living foetus. The human foetus reaches maturity about nine months after conception, but it is capable of living even if born a considerable time before maturity. A child may live when born at seven months or even somewhat earlier, especially if artificial means are taken for preserving its life. When the fcetus is ejected at such a time that in the judgement of a skilled medical man it will probably live, this is called acceleration of birth rather than abortion in the strict sense. We are here concerned with the lawfulness of procuring abortion and of performing such operations as craniotomy and embryotomy, which destroy the life of the fcetus. There is only question of the living, not of the dead, fcetus, as is obvious.

5. Inasmuch as it is never lawful directly to kill the innocent, it is never lawful directly to procure abortion at a time when there is no probability that the foetus can live outside the mother's womb. This is clear, for the fcetus is a human being, with a human soul, which, as is commonly held by theologians, is infused into it by God at the moment of conception; it has, then, as much right to live as anyone else, and it certainly is innocent of all personal crime. To deprive it directly of the medium in which alone it can live is to kill it directly, just as to deprive a man of air by plunging him under water is to kill him directly. The direct procuring of abortion, then, is never allowed, inasmuch as it is the direct killing of the innocent, and intrinsically wrong. In the same way, anticipated homicide and a grievous sin are committed whenever means of whatever sort are taken to prevent conception.

6. However, just as the indirect killing of the innocent is lawful for a just cause, as we have seen, so a pregnant woman who is suffering from disease or tumour, or any complication which threatens life, may lawfully adopt the necessary means to save herself, even if what is a remedy for her causes the death of the foetus. In all these cases we have but the application of the principle of a double effect; the mother is not bound to sacrifice her life by abstaining from adopting the remedy indicated, especially as her own death would also involve the death of the child. Thus we may approve of the following solution by Dr. Capellman of the " case where the uterus with the foetus is locked in the upper strait, as may happen through retroversion, sinking, and prolapsus of the pregnant womb. If all other known means of turning or replacing the uterus fail, I believe it to be allowable to induce abortion indirectly, by procuring the discharge of the waters, or by the perforation
