It is not at all an uncommon thing for women in all ranks of life, to encourage, and even seek removal of the ovaries in order to escape an increase in the family.
They become acquainted with persons who have submitted to this operation for ovarian disease, and noting nothing but improvement in their health, attended by sterility, their intense anxiety to enjoy immunity from child-bearing makes them eager to submit to operation.
It would be distinctly immoral to sterilize healthy women, who become possessed with the old Roman passion for a childless life, or who simply wish to limit their families for any selfish or personal reason.
Any law which recognizes the induction of artificial sterility should make operative interference with those fit to procreate a healthy stock an offence.
Induced sterility should rank with induced abortion, and be a criminal offence, except in certain cases which could be defined.
There is much evidence to suggest that artificial sterilization may become as a great vice, as great a danger to the State as criminal abortion.
Artificial abortion, as commonly performed, is a much more dangerous operation than tubo-ligature.

Of the two operations, any experienced surgeon would readily declare that the latter is the simpler and the safer; the one less likely to lead to unfavourable complications, and the one, moreover, that would leave the subject of it with the better "expectancy of life." Anaesthetics and antiseptics have made this comparison possible and true.
Any surgeon who performs tubo-ligature should be liable to prosecution, unless he can justify his action according to the law relating to the artificial sterility of the unfit.
While the law would eventually require to be obligatory, with regard to the absolutely unfit, it would require to be permissive in all other cases.
Many voluntarily abstain from marriage, because of a strong hereditary tendency to certain diseases such as cancer and tubercle.
There must of necessity be many on the border-land between the fit and the unfit, and clauses permitting sterilization under some circumstances would be required.
CONCLUSION.
In conclusion let us briefly review the whole position taken up in this imperfect study of a great question.

2.

The food-rate is persistently increasing.
