physically
enervated. Those who become dissipated by the use of intoxicating
beverages are not only weak, trifling, and foolish, but walk with an
unsteadiness which betrays their condition. These illustrations show
that this part of the brain is destitute of energy. Diseases of the
digestive organs also indicate it. Cholera, whether induced by invisible
animalcules in the air, or in water, takes the route of the alimentary
canal, opens the vital gates, and myriads of victims are swept down to
death. It proves remarkably fatal to those having this cerebral
conformation. Perhaps enough has been said to indicate the relaxing and
enfeebling tendencies of this region of the brain. They may be
classified as follows:

_REGION OF FEEBLENESS._

/ SERVILITY,
/ CAUTIOUSNESS,
/ FEAR,
Cerebral Functions: { ANXIETY,
\ SENSIBILITY,
\ CUNNING,
\ PROFLIGACY.

/ ATONIC,
Physiological conditions / EXCITABILITY,
and tendencies: { RELAXATION,
\ FEEBLENESS,
\ DISEASE.

This classification shows their tendencies to chronic disease,
functional derangement, insanity, and suicide.

GENERAL CONSIDERATIONS.

Before the structure of the brain was understood, Buffon spoke of it as
a "mucous substance of no great importance." Its functional significance
was so slightly appreciated that some people hardly suspected they had
any brains, until an _accident_ revealed their existence. Latterly,
however, it is generally understood that the perfection of an animal
depends upon the number and the development of the organs controlled by
the nervous system, the sovereign power of which is symbolized by a
grand cerebrum, the throne of Reason. That animal which is so low in the
scale of organization as to resemble a vegetable, belongs to an
ascending series ending in man. The lowest species have no conscious
perception, and their movements do not necessarily indicate sensation or
volition. Instinct culminates in the _Articulates_, especially in
Insects; while created intelligence reaches its acme in man, the highest
representative of the _Vertebrates_.

From mere existence unto life, from life
