The increased mental and moral cultivation of mankind imposes upon them the necessity for greater physical culture. "Wiser and weaker," is a trite saying, and means that the exercise of the higher nature discloses the equivalent necessity of culturing the body, in order to support the increasing expenditures of the former. Mental and moral discipline are essential for a proper understanding how to provide for the body, for physical training increases the capacity of the individual for self-preservation. Constant vigilance is the price of health as well as of liberty.
It is an interesting physiological fact that, while the growth and development of the individual are rapidly progressing, the reproductive powers remain almost inactive, and that the commencement of reproduction not only indicates an arrest of growth, but, in a great measure, contributes toward it. From infancy to puberty, the body and its individual organs, structurally as well as functionally, are in a state of gradual and progressive evolution. Men and women generally increase in stature until the twenty-fifth year, and it is safe to assume that perfection of function is not established until maturity of bodily development is completed. Solidity and strength are represented in the organization of the male, grace, and beauty in that of the female. His broad shoulders represent physical power and the right of dominion, while her bosom is the symbol of love and nutrition. The father encounters hardships, struggles against difficulties, and braves dangers to provide for his household; the mother tenderly supplies the infant's wants, finding relief and pleasure in imparting nourishment, and surrounds helpless infancy with an affection which is unwearied in its countless ministering attentions. Her maternal functions are indicated by greater breadth of the hips. Physical differences so influence their mental natures, that, "before experience has opened their eyes, the dreams of the young man and maiden differ." The development of either is in close sympathy with their organs of reproduction. Any defect of the latter impairs our fair ideal, and detracts from those qualities which impart excellence, and crown the character with perfections. Plainly has Nature marked out, in the organization, very different offices to be performed by the sexes, and has made these distinctions fundamental.
Likewise, Nature expresses the intention of reproduction by giving to plants and animals distinctive organs for this purpose. These are endowed with exquisite sensibility, so that their proper exercise produces enjoyment beneficial to both. Excessive sexual indulgence not only prostrates the nervous system, enfeebles the body, and drains the blood of its vivifying elements, but is inconsistent with intellectual activity, morality, and spiritual development. The most entrancing delights and consummate enjoyments are of the emotive order, ideal, abstract, and pure, so inspiring that they overpower the grosser sensual pleasures and diffuse their own sweet chastity and refining influence over all the processes of life.
Hence, the gratification of the sexual instincts should always be moderate. It should be regulated by the judgment and will, and kept within the bounds of health. No person has a moral right to carry this indulgence so far as to produce injurious consequences to either party, and he who cannot refrain from it is in no proper condition to propagate his species. In all culture there must be self-control, and the practice of self-denial at the command of love and justice is always a virtue. Self-government is the polity of our people, and we point with pride and laudable exultation to our political maxims, laws, and free institutions. The family is the prototype of society. If self-restraint be practiced in the marital relation, then the principle of self-control will carry health, strength, and morality into all parts of the commonwealth. The leading characteristics of any nation are but the reflection of the traits of its individual members, and thus the family truly typifies the practical morality and enduring character of a people.
OVULATION.
The Ovaries are those essential parts of the generative system of the human female in which the ova are matured. There are two ovaries, one on each side of the uterus, and connected with it by the Fallopian tubes; they are ovoidal bodies about an inch in diameter, and furnish the germs or ovules. These latter are very minute, seldom measuring 1/120 of an inch in diameter, and frequently are not more than half that size. The ovaries develop with the growth of the female, so that, finally, at the pubescent period, they ripen and liberate an ovum, or germ vesicle, which is carried into the uterine cavity through the Fallopian tubes. With the aid of the microscope, we find that these ova are composed of granular substance, in which is found a miniature yolk surrounded by a transparent membrane, called the zona pellucida. This yolk contains a germinal vesicle in which can be discovered a nucleus, called the germinal spot. The process of the growth of the ovaries is very gradual, and their function of ripening and discharging an ovum every month into the Fallopian tubes and uterus is not developed until between the twelfth and fifteenth years.
This period, which indicates, by the feelings and ideas, the desires and will, that the subjects are capable of procreation, is called puberty. The mind acquires new and more delicate perceptions, the person becomes plumper, the mammæ enlarge, and there is grace and perfection in every movement, a conscious completeness for those relations of life for which this function prepares them. The period of puberty is also indicated by
MENSTRUATION.
The catamenial discharge naturally follows the ripening and liberation of an ovum, and as the ovaries furnish one of these each month, this monthly flow is termed the menses (the plural of the Latin word mensis, which signifies a month). The menstrual flow continues from three to five days, and is merely the exudation of ordinary venous blood through the mucous lining of the cavity of the uterus. At this time, the nervous system of females is much more sensitive, and from the fact that there is greater aptitude to conception immediately before and after this period, it is supposed that the sexual feeling is then the strongest. When impregnation occurs immediately before the appearance of the menses, their duration is generally shortened, but not sufficiently to establish the suspicion that conception has taken place. The germ is the contribution of the female, which provides the conditions which only require the vivifying principle of the sperm for the development of another being. The period of aptitude for conception terminates at the time both ovulation and menstruation cease, which, unless brought about earlier by disease, usually occurs about the forty-fifth year of her age.
