Tracing the development of sex life there is a certain order of events in a normal history. Before puberty, the ova have lain asleep, as it were, in a cocoon state. Now with puberty they awaken. And with them all those profound mechanisms and inventions that have to do with their nutrition up to ripening. Then revolve the cycles that are translated as menstruation, the propulsion, fertilization and implantation of the ova in the uterus,--the full development of the fetus,--its birth, and feeding after birth--all of which are ductless gland controlled. Samuel Butler once noted that: "All our limbs and sensual organs, in fact, our whole body and life, are but an accretion round and a fostering of the spermatozoa. They are the real "He." A man's eyes, ears, tongue, nose, legs and arms are but so many organs and tools that minister to the protection, education, increased intelligence and multiplication of the spermatozoa, so that our whole life is in reality a series of complex efforts in respect of these, conscious or unconscious according to their comparative commonness. They are the central fact in our existence, the point towards which all effort is directed." Nothing could be said more truly of Woman, and the ova she carries. All that transpires during pubescence is symptomatic of the underlying tidal stir in the cells. The uterus becomes gorged with blood periodically, to provide an enriched soil for the perhaps to be fertilized ovum to plant itself. The breasts grow, and fat is deposited in particular places as reserve material for the making of milk. The qualities which are to appeal to the eye and ear and even nostrils of the male appear. Instincts dawn, an independence of spirit germinates, emulsified with a curious shyness and coyness and a desperate loneliness and secrecy. And all because there have been let loose in the blood from the glands of internal secretion the chemical substances that set going the clockwork of sequential incidents elaborated and repeated through countless aeons of time. FEMININE PRECOCITY Ordinarily, in the north temperate climate, puberty begins about the fourteenth year, but may begin anywhere from the tenth to the sixteenth. Feeding and environment indirectly, the state of the internal secretions as a whole directly, determine this. In girls, those definite signs, menstruation and the growth of the breasts, before the age of ten, mean premature awakening of the ovaries and a concomitant co-reaction of the other endocrines, creating the ensemble of maturity.
