The feminine pituitary personality, in whom there is predominance of the post-pituitary over the ante-pituitary, occurs in men. The type is short, rounded and stout. They have heads that seem too large for their bodies, the general hair distribution on the trunk and extremities is poor, although that of the scalp and face is plentiful, and they acquire an abdominal paunch early. They exhibit the feminine tendency to periodicity of function, their moods, activities, efficiency are cyclic, reminding one of the menstrual variations of the female. This rhythmicity saturates their personalities, so that poetry and music almost morbidly appeal to them. A number of the great poets and musicians are to be classified as of the feminine pituitary species. Last, but not least, they are the hen-pecked lovers and husbands. Sex difficulties are frequent in their history. The determination of endocrine type and tendencies, the prediction of the future personality, during childhood is one of the developments confidently to be looked for, as our knowledge of the internal secretions will grow. The possibilities of control loom as one of the most magnificent promises of science. Yet the high expectations for tomorrow should not depress our respect for the achievements of today. In the case of the pituitary, for instance, a hint as to the method of approach is furnished by the tabulation of the traits of pituitary dominance and pituitary inferiority in children. Pituitary sufficient and dominant: Large, spare, bony frame Eyes wide apart Broad face Teeth, broad, large, unspaced Square, protruding chin and jaws Large feet and hands Early hair growth on body Thick skin, large sex organs Aggressive, precocious, calculating, self-contained Pituitary inferior: Small, sometimes delicate skeleton Rather adipose, weak muscles Upper jaw prognathous Dry, flabby skin Small hands and feet Abnormal desire for sweets Subnormal temperature, blood pressure and pulse Poor control of lower vegetative functions Mentally sluggish, dull, apathetic, backward Loses self-control quickly, cries easily, discouraged promptly, psychic stamina insufficient The pituitary personality in childhood produced by limitation of the size of the gland, because its bony box is completely or partially closed, presents typical hall-marks. He supplies the second and third offenders in the juvenile courts, the delinquents and pathological liars of childhood, the incorrigibles, the precocious hoboes, mental and moral deficients and defectives, the prey of the sentimental complexes of elderly virgins and helpful futility all around. Not utilitarianism or futilitarianism is needed, but pituitarianism. The feeding of pituitary gland in large enough quantities to these unfortunates may do more than ten charity organizations, with the most patrician board of directors complete.
