,
the general lines of his life, diseases, tastes, idiosyncrasies and
habits.

11. Within limits, if the previous history of an individual is known,
his physical appearance may be approximately described, and his future
outlined.

12. Conversely, given the physical and psychic composition of an
individual, and his past history, one may deduce the internal
secretion type to which he belongs.

Examples:

A. One Thyroid-centered Type has
Bright eyes
Good clean teeth
Symmetrical features
Moist flushed skin
Temperamental attitude toward life
Tendency to heart, intestinal and nervous disease

B. One Pituitary-centered Type
Abnormally large or small size
Musical--acute sense of rhythm
Asymmetrical features
Tendency to cyclic or periodic diseases

C. One Adrenal-centered Type
Hairy
Dark
Masculinity marked
Tendency to diphtheria and hernia

These are some of the master types. They have their variants depending
upon the influences of the other glands, especially the interstitial
cells of the sex glands.

ANTE-NATAL DEVELOPMENT

In their ensemble, the glands of internal secretion wield a
determining influence upon the development of the individual from
his very inception. If his various powers may be conceived of as an
orchestra, they may be said to conduct it from the very beginning of
its movements, and to cease only with its termination. From the moment
when the spermatozoon penetrates and fecundates the ovum, the fate
of the future being is settled by their disposition. The seal of his
destiny is soaked with their substance.

POST-NATAL DEVELOPMENT

Every particle of protoplasm, every granule of the impregnated ovum
carries the representatives of the parental ductless glands. As a
consequence, they transmit chemically, with no figure of speech
involved, the peculiar familial, racial and national characters from
progenitors to offspring. They confer upon the child a number of the
properties commonly recognized as inherited. All those features which
distinguish Caucasian from Mongolian, Scandinavian from Italian,
Italian from Jew are determined by them.

In short, at every step of his life, in every relation and
association, in every expression of the inner forces that control his
being, the normal individual is influenced by his internal secretions.
Let us now see how.
