“The sexual instinct has been given to man for the perpetuation of his species; but in order to refine this gift and set limits to its abuse, it has been wisely ordered that a purely intellectual quality――that of love――should find its most passionate expression in the gratification of this instinct. Dissociate the one from the other, and man sinks below the level of a brute. Destroy the reciprocity of the union, and marriage is no longer an equal partnership, but a sensual usurpation on the one side and a loathsome submission on the other. Consider the moral effects of such shameful manœuvres: wedlock lapses into licentiousness; the wife is degraded into a mistress; love and affection change into aversion and hate. Without suffering some penalty, man cannot disturb the conditions of his well-being or trespass beyond its limitations. Let him traverse her physical laws and Nature exacts a forfeit: dare he violate his moral obligations, an offended Deity stands ready to avenge them. That this law is immutable, witness, from the history read to you, the estrangement between the husband and wife; witness his ill health and ill temper, and the wreck of body and mind to which she has been reduced.” Again, from the _Medical Advance_ for 1876, we find the following language written by Dr. Arnalt: “There is one phase of sexual depravity to which I would, in passing, call your attention. “We are fully aware of the many devices used to avoid impregnation. It may be well to remember that such desires may, under certain circumstances, be excusable; but let us never forget the fact that generally they are conceived in iniquity. “Of the many ways of avoiding possible conception, there is one so filthy, mean and degrading, and fraught with such fearfully disastrous consequences to health, that I make special mention of it. I have reference to the practice of withdrawing the male organ from the vagina before the completion of the embrace. “But when man brings to the marriage-bed so foul a nature that he can repeatedly and constantly perpetrate such an outrage upon nature’s most precious gifts, he places himself at once beyond the desert of human sympathy.
