A fetus, then, of six calendar, or solar, months (not lunar) is viable if treated in a hospital by competent physicians. Otherwise it is not viable, except in a strictly technical sense; it will not live more than a few days or weeks. Reports of infants younger than six months as having been successfully reared are not credible--it is easy to make an error in the reckoning. A full seven-months infant may be reared with proper feeding and skilled care; a six-months infant may be reared (with difficulty) in a hospital with skilled care. If it is certain that the removal of a six-months fetus will here and now save the life of a mother (a very difficult matter to judge by the best diagnosticians), this removal may be done, provided the infant is delivered in circumstances where skilled care, incubator, and proper food are obtainable; otherwise the removal is not justifiable. That the ordinary physician says it is necessary to empty the uterus is not a sufficient reason, as he is likely to act from ill-digested information set forth by professorial pagans, who place no value whatever on human life in an infant. A most important and essential circumstance in the matter of inducing abortion at the end of the sixth month of gestation to save a mother's life is that in practically every case requiring such interference the diseased condition of the mother has checked the growth of the fetus, and the fetus therefore is really not a six-months child in development. Such an undeveloped fetus is not viable. Eclamptic women, and those who have nephritis, are most likely to have undeveloped fetuses. In cases of this kind the seventh month should be completed before interference. How is this human body in all its complexity developed from the microscopic germ-cells? There has been a vast deal of ink spilled in striving to solve this mystery, but we come out empty by the same door wherein we went. The early Preformationists guessed that the ovum contains an embryo fully formed in miniature, and development is a mere unfolding of what had already existed. The biologists of to-day mention the Preformationists with superior scorn, and then present Preformationism under other names. Weismann's theory is the most fashionable at present.
