# Searchlights on Health/The Mysteries of the Formation of Life

THE MYSTERIES OF THE FORMATION OF LIFE.
1. SCIENTIFIC THEORIES.—Darwin, Huxley, Haeckel, Tyndall, Meyer, and other renowned scientists, have tried to find the missing link between man and animal; they have also exhausted their genius in trying to fathom the mysteries of the beginning of life, or find where the animal and mineral kingdoms unite to form life; but they have added to the vast accumulation of theories only, and the world is but little wiser on this mysterious subject.
2. PHYSIOLOGY.—Physiology has demonstrated what physiological changes take place in the germination and formation of life, and how nature expresses the intentions of reproduction by giving animals distinctive organs with certain secretions for this purpose, etc. All the different stages of development can be easily determined, but how and why life takes place under such special condition and under no other, is an unsolved mystery.
3. OVARIES.—The ovaries are the essential parts of the generative system of the human female in which ova are matured. There are two ovaries, one on each side of the uterus, and connected with it by the Fallopian tubes. They are egg-shaped, about an inch in diameter, and furnish the germs or ovules. These germs or ovules are very small, measuring about 1/120 of an inch in diameter.
4. DEVELOPMENT.—The ovaries develop with the growth of the female, so that finally at the period of puberty they ripen and liberate an ovum or germ vesicle, which is carried into the uterine cavity of the Fallopian tubes. By 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 one ovum monthly into the Fallopian tubes and uterus, is not completed until between the twelfth and fifteenth years.
5. WHAT SCIENCE KNOWS.—After the sexual embrace we know that the sperm is lifted within the genital passages or portion of the vagina and mouth of the uterus. The time between the deposit of the semen and fecundation varies according to circumstances. If the sperm-cell travels to the ovarium it generally takes from three to five days to make the journey. As Dr. Pierce says: The transportation is aided by the ciliary processes (little hairs) of the mucous surface of the vaginal and uterine walls, as well as by its own vibratile movements. The action of the cilia, under the stimulus of the sperm, seems to be from without, inward. Even if a minute particle of sperm, less than a drop, be left upon the margin of the external genitals of the female, it is sufficient in amount to impregnate, and can be carried, by help of these cilia, to the ovaries.
6. CONCEPTION.—After intercourse at the proper time the liability to conception is very great. If the organs are in a healthy condition, conception must necessarily follow, and no amount of prudence and the most rigid precautions often fail to prevent pregnancy.
7. ONLY ONE ABSOLUTELY SAFE METHOD.—There is only one absolutely safe method to prevent conception, entirely free from danger and injury to health, and one that is in the reach of all; that is to refrain from union altogether.
