roper educational stimulus is supplied. Men
of brains, practical and theoretical, philosophers, thinkers, creators
of new thoughts and new goods, belong to this group. The distinction
between men of theoretical genius, whose minds which could embrace
a universe, and yet fail to manage successfully their own personal
everyday lives, and the men of practical genius, who can achieve and
execute, the great engineers, and industrial men lies in the balance
between the ante-pituitary and the adrenal cortex primarily. Men like
Abraham Lincoln and George Bernard Shaw belong to this ante-pituitary
group.

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.
