and masculinoid traits, the adrenal inferior will have a low
blood pressure and suffer from a constant weakness and fatigability.
So each form of reaction to the critical ages is individualized
according to the predominating glandular influence in the constitution
of the woman. When the womb has atrophied, and the breasts have
shrunk, the typical tan complexion, and the angular masculinoid
figure, face and psyche follow, and the transfiguration has been
completed.

Man has his critical age of sex cell deterioration as well as woman.
The age period swings between forty-five and fifty-five. Here enters
upon the scene that organ of external and internal secretion, the
prostate, the most important of the accessory sex glands in the male.
Experiments with its extract upon growing tadpoles have demonstrated
it to have the same differentiating effects as thyroid, but without
the poisoning effects. Furthermore, the microscope reveals cyclic
changes in its cells comparable to the menstrual phenomena of the
uterus. Indeed it is accepted as the homologue or male representative
of the uterus. Small and undeveloped during childhood, its growth at
puberty parallels that of the other reproductive organs. Its secretion
has been shown to be necessary to the vitality of the sperm cells.
The regression of the prostate, its retirement from the field of
sex competition, is the central episode of the male climacteric.
Accompanying its shrinking are prominent an irritable weakness,
despondency, and melancholia, which may emerge at any time if there is
disease or disturbance of it. The influence of the prostate upon man's
mental condition, and its contribution to the sex index, still remains
to be investigated in detail.

SEX CRISES

At the periods of interstitial cell hyperactivity, when a wave
of radicalism in the blood sweeps through the tissues, the other
endocrines are tested, and their latent stability or instability is
made manifest. Even before puberty, cyclic variations of health and
conduct may be observed in boys and girls which undoubtedly depend
upon currents among the internal secretions. Children, who, in the
best of circumstances, habitually are attacked by a wanderlust and run
away from home, or suffer from fits of naughtiness, are samples of
such endocrine lability. Children specialists have found that at about
the end of the second year their charges begin to individuate. In a
certain percentage, sex traits appear prett
