ing crises especially, control the production and
supply of energy to the various organs and tissues called upon to
function to the utmost in emergencies. When the adrenals fail, as they
do readily in these labile adrenocentrics, it is as if the adrenals
were cut out of the body. And it has been repeatedly shown that
extirpation of the adrenals is immediately followed by degeneration
and breakdown of the brain cells.

These facts explain the reactions of Lieut. B. The acute call upon his
adrenals made by his dangerous situation probably soon exhausted them
of their content of reserve secretions. Overwhelming fatigue with loss
of muscle tone followed. The changes in the brain caused him to talk
as he did in the wilderness. Returned to safety, the news that his
reputation was under fire because of C.'s letter brought out another
adrenal characteristic: the excessive instinct of pugnacity, easily
stimulated, with its emotion of anger and the tendency to violence.
What is spoken of as a quick temper is an adrenocentric trait.
Returned to New York, an infection, tonsillitis, attacked him.
Infections in adrenocentrics use up the content of the adrenals as
rapidly as physical exhaustion or emotion. So the tonsillitis, which
in another type of individual would have been combatted continuously
by the adrenals and so passed by as a mere sore throat, presented him
with a high temperature, and the brain disturbance described by the
medical officer as exhaustion-psychosis, with again a tendency to
violence. In short, the history of his adventure is the history of his
adrenals under stress and strain. It illustrates the mechanism of a
typical endocrine neurosis.

THE UNCONSCIOUS AND THE VISCERA

In the chapter on the glands of internal secretion as an interlocking
directorate, certain generalities were stated as the laws of the
government of the organism's life by them in association with the
vegetative apparatus. It was put forward as a fundamental revision of
the theory, hitherto accepted, of the limitation of mind to the brain
cells. We think and feel not alone with the brain, but with our
muscles, our viscera, our vegetative nerves, and last but not least
our endocrine organs. In short, we think and feel with each and every
part of ourselves.

Among these pristine factors determining the content of consciousness,
the endocrines are most important, because they alone to start with,
of all the other factors, are different in e
