chanisms of suppression of the mind render it incapable of
appreciating horror until encountered. And so thousands with
dangerously unstable adrenals were plunged into the most trying
conditions possible. Hundreds of them, already shaken, on the
borderland of instability, reacted with the phenomena of breakdown
of control, lumped with a host of other phenomena, under the general
rubric of "shell shock."

That alone was not all. If hundreds collapsed, thousands approached
the verge of collapse. They survived and were discharged from the
armies as normal. They reappear in civil life as cases of "nerves."
Ordinarily that would mean that they would be classed as failures. But
such have been the psychologic reactions to the war that all kinds
of compensations in the way of dangerous mental states have become
frequent in these inadequate adrenal types. A trend to violence and a
resentful emotionalism are combined with desperate attempts to spur
the jaded adrenals with artificial excitements. Consequent melancholia
and depression, the "blues," are inevitable. A survey of drug addicts
would probably show a definite percentage of this type. The same
applies to certain petty criminals and law breakers.

The adrenal element in the personality must be considered in every
disturbance, morbid, personal, or social involving brunette types,
Huxley's dark white, Mediterranean-Iberians, red-haired persons, and
even pigment-spotted fair people. Historians have traced the earliest
civilization to the doings of a brunette people, the Sumerians, the
first to build cities in the Euphrates-Tigris region more than five
thousand years before Christ was born. An adrenalized people one
would, expect to be the first to take advantage of possibilities
because of their energy capacity. The earliest Sumerian stone carvings
of warriors exhibit an undersized skeleton compared with the large
head, broad face, a low hair line and prominent nose that would fit
into the ensemble of the adrenal type. Certain other historical
aspects of the adrenal personality have yet to be worked out.

THE PITUITARY PERSONALITIES

The presence of two antagonistic elements in the one gland complicates
any attempt at even the most abstract analysis of a personality
dominated by that gland. The pituitary, composed of an anterior lobe
and posterior lobe, supplies two fairly uncomplicated corresponding
types, best described as the masculine pituitary type, and the
feminine
