Endocrine inferiority is indeed the most frequent organic inferiority.  And we may explain a number of mental types upon that basis.  Thus the inferior gonado-centric, who has something wrong with his reproductive organs, will evolve in one of two directions.  If his adrenal and thyroid are of poor quality, he will become the secluded introvert, shut off from the interests of normal life.  He will enter the borderland of insanity if pituitary difficulties supervenes.  If, on the contrary, the adrenal, thyroid and pituitary are present in a certain proportion, he will become the active, aggressive, never-resting, keen, and relentless fanatic reformer.  A woman who is gonad deficient with a superior adrenal will suffer from virilism and specialize in the extreme tactics and mythology of the feminist movement.  A number of life reactions are classifiable as the strivings of endocrine inferior individuals to overcome their sense of inferiority.  The unconscious vegetative system and the system of consciousness are both modified by the weakness of a link in the glandular chain.

What, therefore, is to be recommended in the prophylaxis of the natural deterioration of the wells of life, the ductless glands?  For even if we may be able to replenish them when they dry up, would it not be better to delay their dessication?  The hormones reply to every call of life and respond in every reaction.  The normal constructive process of their cells remanufactures what has been lost, and the original capacity to respond is restored.  If, though, the rate of destruction and loss outruns the rate of repair and construction, they will be permanently damaged.  This is what occurs in shock, serious, severe accidents and injuries, prolonged infections and diseases, profound continued emotions, and the wear and tear of overwork.  The prevention of these excessive fatigues of the endocrine system in one or all of its parts, and especially the prevention and enfeeblement of the diseases of children which injure them at a period when they are most sensitive to injury, is the task of the endocrine hygienist.  Periodic examinations, to check up the balance sheets of the hormone factories and to measure the amount of their damage by means of blood analyses, will provide the most valuable method in the campaign to lengthen the productive and enjoying span of life.

THE TREATMENT OF CRIME

Endocrine hygiene will discover no wider or more fruitful area for exploration and control than that of crime.  For more than a generation there have been attempts at a criminology, and a new understanding and control of crime.  In the United States a concomitant sentimentalism has concocted measures like the honor system which, naturally failing of their purpose, have undermined confidence in the idea of scientific diagnosis and treatment of crime.  As someone has noted, to ask a criminal to promise not to misbehave, when discharged
