Post-pituitary in excess, without compensation or balancing by one or some of the other endocrines, is associated with an instability of mood and the organic outlook. Concomitant is a defective self-control. Typically, one sees the effects in the mental abnormalities of women during the premenstrual period.
And as Life always has worked with a large margin of safety, and always played for safety first as regards quantity, these variations have not become of much significance for the history and destiny of the animal. But variations among the endocrines made a tremendous difference.
Let there be relatively too much of it, too little of the other glands, and the grosser transfigurations and ailments of the child-bearing period follow. Once pregnancy is terminated by labor, the placenta is expelled from the body as the after-birth. The placenta removed, a new arrangement of the balance of power among the endocrines becomes necessary.
This masculine element causes a rearrangement of the balance of power between the endocrines towards the side of masculinity. They push down the pan of the scale to inhibit the post-pituitary. So menstruation, the menstrual wave which follows the increasing tide of post-pituitary secretion, is postponed.
But a new-comer appears upon the scene to take up the function left vacant by the absent placenta. This new-comer is the secretion of the activated breasts, the mammary glands. They make for a persistence of the state of equilibrium among the endocrines attained during pregnancy. The mammary glands are typical glands of external secretion.
Training or education involves, beside other effects, a training of the endocrines, and hence of the entire vegetative apparatus, to respond in a particular way to a particular stimulus. Experience is like the introduction of new push-buttons, levers, and wheels into the mechanism.
Variation and resemblance are large issues, crucial material of the science of biology upon which much has been thought and written. That the proportion of the endocrines determines variation and resemblance, heredity and evolution is a hypothesis advanced, supported by a large amount of facts, and capable of the most interesting experimental verification and observation.
The endocrines control the transport, and course, combinations and permutations in the history of lime's progress among the cells, and are in turn themselves affected by it. Man is relatively free of these liabilities, and so remains man by his freedom from the recurrent crises involving the lime salt reserve which constitute the essence of the life story of woman.
The whole system, viscera, visceral nerves and the endocrines gradually united into a complete autonomous organism within the organism, and as such functions as the vegetative apparatus. In the course of evolution, variations occurred in all three components of the apparatus, the viscera, the nerves, and the endocrines.
Before menstruation, there is a stage of preparation, a stir and twittering of the endocrines, the premenstrual state. Currents of communication flow between the different glands, messages and replies pass to and fro. When these are properly balanced, so that all goes well, the consciousness of the woman will be disturbed by no knowledge of them.
