The foetal blood is transmitted to and fro between the body of the child and the placenta, by a cord which contains two arteries and one vein. This is called the umbilical cord, because it enters the body at the middle of the abdominal region, or umbilicus. It is composed, also, of its own proper membranous sheath, or skin, and cellular tissues, besides the blood-vessels. Two months after pregnancy, this cord can be seen, when it commences to grow rapidly.
QUICKENING.
Not until the mother feels motion is she said to be quick with child. That is, the child must be old and strong enough to communicate a physical impulse, which the mother can distinctly perceive, before it is regarded as having received life. This is a fallacy, for the germ has to be endowed with life before organization can begin. The act of impregnation communicates the vital principle, and from that moment it starts upon its career of development. A long period elapses after this occurs before it can make the mother feel its motions. Before quickening, the attempt to destroy the foetus is not considered so grave a crime by our laws, but after this quickening takes place, it is deemed a felony.
THE RIGHT TO TERMINATE PREGNANCY.
The expediency and the moral right to prematurely terminate pregnancy must be admitted when weighty and sufficient reasons for it exist. Such a course should never be undertaken, however, without the advice and approval of the family physician, and, whenever it is possible, the counsel of another medical practitioner should be obtained. There may be so great a malformation of the pelvic bones as to preclude delivery at full term, or, as in some instances, the pregnant condition may endanger the life of the mother, because she is not able to retain nourishment upon the stomach. In such cases only, is interference warranted, and even then the advice of some well-informed physician should be first obtained, to make sure that the life of the mother is endangered before so extreme a measure is resorted to.
Those who are qualified for maternal duties should not undertake to defeat the intentions of nature, simply because they love ease and dislike responsibility. Such persons may be considered genteel ladies, but, practically, they are indifferent to the claims of society and posterity. How such selfishness contrasts with the glorious, heroic, Spartan spirit of the young woman who consulted us in reference to the acceptance of a tempting offer of marriage! She was below medium size and delicately organized. She hesitated in her answer, because she was uncertain as to her duty to herself, and to her proposed husband, and on account of the prospective contingencies of matrimony. After she was told that it was doubtful whether she could discharge the obligations of maternity with safety to herself, and yet that she might prove to her intended husband a true and valuable wife, she quickly answered, her black eyes radiant with the high purpose of her soul: "If I assent to this offer, I shall accept the condition and its consequences also, even if pregnancy be my lot and I know it will cost me my life!" She acceded to the proposal, and years found them one in happiness; then a daughter was born, but the bearing and nursing were too much for her delicate constitution, and she continued to sink until she found rest in the grave. Of all her beautiful and noble sayings, none reflect more moral grandeur of spirit than the one in which she expressed her purpose to prove true to posterity.
THE SIGNS OF PREGNANCY.
The symptoms which indicate pregnancy are cessation of the menses, enlargement of the mammæ, nausea, especially in the morning, distention of the abdomen, and movement of the foetus. A married woman has reason to suspect that she may have conceived, when, at the proper time, she fails to menstruate, especially when she knows that she is liable to become pregnant. A second menstrual failure strengthens this suspicion, although there are many other causes which might prevent the appearance of the menses, such as disease of the uterus, general debility, or taking cold, and all of these should be taken into account. In the absence of all apparent influences calculated to obstruct the menses, the presumption ordinarily is that pregnancy is the cause of their non-appearance. The evidence is still more conclusive when the mammæ and abdomen enlarge after experiencing morning sickness. Notwithstanding all these symptoms, the audible sound of the heart, or the movements of the foetus, are the only infallible signs of a pregnant condition.
THE DURATION OF PREGNANCY.
The ordinary duration of pregnancy is about forty weeks, or 280 days. It is difficult to foretell exactly when a pregnancy will be completed, for it cannot be known precisely when it began. Some gestations are more protracted than others, but the average duration is the time we have given. A very reasonable way to compute the term, is to reckon three months back from the day when the menses ceased and then add five days to that time, which will be the date of the expected time of confinement. It is customary, also, for women to count from the middle of the month after the last appearance of the menses, and then allow ten lunar months for the term. This computation generally proves correct, except in those instances in which conception takes place immediately before the fast appearance of the catamenia. A few women can forecast the time of labor from the occurrence of quickening, by allowing eighteen weeks for the time which has elapsed since conception, and twenty-two more for the time yet to elapse before the confinement. With those in whom quickening occurs regularly in a certain week of pregnancy, this calculation may prove nearly correct.
