The same laws which regulate the perfection of plants, the growth of corn, the fleetness of the greyhound, and the symmetry of the horse, govern the physical and mental culture of man. In the vegetable kingdom, the agriculturalist is aware that the success of his crops depends upon the condition of what he sows, and the fertility of the soil wherein it is sown. It is precisely the case with the propagation of the human species. The race may be improved, or deteriorated, accordingly as the laws which govern the continuance of mankind are more or less observed. But we are digressing from the subject of which we intended to speak—that of the transmission of diseases from parent to child. Parents exercise a mighty influence over the physical condition of their offspring,—the general constitution, mental and physical qualities, and even individual peculiarities, being transmitted from sire to son. Premature marriage, and, consequently too early sexual congress, although it may not prove detrimental to the parents, except where its privileges are intemperately exercised, may be, and often is a great disadvantage to the children, they being generally delicate, imperfect, and seldom arriving at maturity. The same results follow, where the parents, or either of them are at the moment of conception in ill-health. And shall the circumstances of early marriage, or a bad state of health, debar the sexes from the satisfaction of the holiest and most ennobling of the passions? Would it not be far more just and moral, then, to make use of a preventive of conception, when from motives of economy, offspring is not desired, or, from the reasons mentioned above, health cannot be given at the same time that life is imparted? The candid reader will have but one answer. Physicians, generally, when referring to the subject of the transmission of disease, lay it down as a law, that persons so affected should not marry. Here we beg leave to differ from them, and, we think, justly. Consumptive or scrofulous persons certainly should not beget offspring; but we cannot see why they should be prevented from enjoying the pleasures of the married state. It is necessary for the general health of an individual, that the sexual embrace should be occasionally enjoyed—indeed it is an established fact, that many of those women who die unmarried, owe their early death, to a species of consumption, excited by deprivation of the sexual act. We think therefore, that all ought to be married, and that those who cannot produce healthy progeny, should make use of means to prevent conception.
