The more highly-organized the mother, the more child-bearing exhausts her, because she is drained of her intellectual and spiritual forces. She, therefore, requires longer periods of rest and recuperation than the healthy, animal woman who can bear a child every two years for many succeeding years, and retain health and vigor. Many of the most lovely, most charming, and altogether admirable women, become the inmates of insane asylums from having maternity thrust on them at too near periods of time. For a child to be well born, his parents should be happily mated and in good health; the coming together should be mutual, and with a willingness, if not a desire, for parentage. Quite infrequent relations, if any, should take place up to the fourth month. This should, of course, be left entirely to the wife’s decision--to her feeling of what is right and best for _her_. I have known wives very desirous of having children, who, on finding themselves pregnant, could not help turning with glad affection to the father of the child. Nothing is as yet proved on this head, and there is no telling what magnetisms may or may not be furnished the embryo at this early stage. Nature in the woman refuses to entertain the thought of sexual commerce after the fourth month. SLEEPING. There are many reasons which make it most unadvisable for husband and wife to occupy the same bed, and growing physiological knowledge will sooner or later effect a change in this, as in many other of our habits. In the first place, it is not desirable in this way to equalize the magnetism of the two parties. Part of the mutual attraction is thus lost. Then sleep is not so wholly undisturbed and refreshing as when one is quite alone. But most important of all, the mere fact of contact often arouses the animal when the will and judgment are asleep, and a base union takes place, which is followed by regret, shame, and bodily weakness. A late writer on marriage, parentage, and kindred subjects takes the ground that the sexual attraction exists solely for the production of offspring. He gives the impression that, unless the minds of the parties concerned are filled with the desire for parentage, the physical union is wholly sensual and unjustifiable. Here the experience of the very best men and women who should certainly give us a standard, if one is possible, goes contrary to this view, and certainly we ought not to discard this testimony for that of the unspiritual animal world, especially when this varies from the human in being polygamous, and each season choosing another mate; neither can it be supposed that the animal of intuition creates offspring.
