The child, previous to birth, never takes nutriment in by its mouth, for that is always firmly closed until after birth. Its food during gestation is probably derived from the blood of its mother through the umbilical cord, or navel-string, which likewise supplies its veins and arteries until the very hour of birth. An artery and two veins pass through this cord. There is sometimes an impediment in the circulation of new-born infants, which is called the blue disease, and for which there is no remedy. In these cases the body is of a leaden blue color, and the child appears sleepy and inanimate. Such children usually die before they are a year old, though sometimes they live four or five years. SEXUAL INDULGENCE. Most men are of an amative disposition, and after the age of puberty have frequent desires to indulge in sexual intercourse. Some feel this desire so overpoweringly that everything else is forgone, all risks are run, and consequences madly braved, merely for the gratification of a momentary passion. Females, on the contrary, are seldom troubled with sexual desires; and among those who risk their reputation and their social existence in the gratification of illicit love, few are prompted to the act by the amative feeling. It is the idea that they are loved, and the wish to impart pleasure to the loved object, that overpowers their own judgment. When once a man has gained the love of a true female heart, it lies in his power to use her person at will. Very few of the weaker sex can withstand the promptings of disinterested affection; but their sexual passions seldom lead them astray.
